Chapter I described what benzodiazepines do when they are in the body and how tolerance and dependence develop. Chapter II discussed the need for slow withdrawal and gave practical examples of dosage tapering. This chapter is concerned with what happens as benzodiazepines leave the body in the course of withdrawal and afterwards. The focus is on withdrawal symptoms, and how to cope with them if they occur.

It cannot be too strongly stressed that withdrawal symptoms can be minimised and largely avoided by slow tapering, tailored to the individual's needs as outlined in Chapter II. However, some long-term benzodiazepine users begin to experience "withdrawal" symptoms even though they continue taking the drug. This is due to the development of drug tolerance (Chapter I) which sometimes leads doctors to increase the dosage or add another benzodiazepine. Analysis of the first 50 patients who attended my benzodiazepine withdrawal clinic showed that all of them had symptoms on first presentation while still on benzodiazepines (12 of them were taking two prescribed benzodiazepines at once). Their symptoms included the full range of psychological and physical symptoms usually described as benzodiazepine withdrawal symptoms. The process of slow benzodiazepine tapering in these patients caused only slight exacerbation of these symptoms, which then declined after withdrawal.

People who develop severe symptoms on benzodiazepine withdrawal have usually come off the drugs too rapidly. Lack of explanation of the symptoms has often added to their distress and has introduced fears ("Am I going mad?") which themselves magnify the symptoms. A few, because of these frightening experiences, have ended up with a condition akin to post-traumatic stress disorder (PTSD). But a proper understanding of the reasons for and nature of any symptoms that arise can do much to allay the bewilderment and fear associated with benzodiazepine withdrawal and can also help prevent long-term sequelae. Withdrawal reactions are in fact a normal response to the discontinuation of many chronically used drugs including alcohol, opiates, antipsychotics, antidepressants, and even some medications for angina and hypertension.

Mechanisms of withdrawal reactions. Drug withdrawal reactions in general tend to consist of a mirror image of the drugs' initial effects. In the case of benzodiazepines, sudden cessation after chronic use may result in dreamless sleep being replaced by insomnia and nightmares; muscle relaxation by increased tension and muscle spasms; tranquillity by anxiety and panic; anticonvulsant effects by epileptic seizures. These reactions are caused by the abrupt exposure of adaptations that have occurred in the nervous system in response to the chronic presence of the drug. Rapid removal of the drug opens the floodgates, resulting in rebound overactivity of all the systems which have been damped down by the benzodiazepine and are now no longer opposed. Nearly all the excitatory mechanisms in the nervous system go into overdrive and, until new adaptations to the drug-free state develop, the brain and peripheral nervous system are in a hyperexcitable state, and extremely vulnerable to stress.

Acute withdrawal symptoms. The most prominent effect of benzodiazepines is an anti-anxiety effect - that is why they were developed as tranquillisers. As a consequence, nearly all the acute symptoms of withdrawal are those of anxiety. They have been described in anxiety states in people who have never touched a benzodiazepine and were recognised as psychological and physical symptoms of anxiety long before benzodiazepines were discovered. However, certain symptom clusters are particularly characteristic of benzodiazepine withdrawal. These include hypersensitivity to sensory stimuli (sound, light, touch, taste and smell) and perceptual distortions (for example sensation of the floor undulating, feeling of motion, impressions of walls or floors tilting, sensation of walking on cotton wool). There also appears to be a higher incidence than usually seen in anxiety states of depersonalisation, feelings of unreality, and tingling and numbness. Visual hallucinations, distortion of the body image ("my head feels like a football/balloon"), feelings of insects crawling on the skin, muscle twitching and weight loss are not uncommon in benzodiazepine withdrawal but unusual in anxiety states.

Table 1 gives a list of symptoms which were spontaneously described by patients in my withdrawal clinic. It is clearly a long list and is probably not inclusive. Of course, not all patients get all the symptoms, and none of the symptoms are inevitable. Withdrawal often seems to seek out the individual's most vulnerable points: if he is prone to headaches, worse headaches may feature in withdrawal; if he is prone to "irritable bowel", digestive symptoms may be aggravated. Such symptoms are nearly always temporary and can be minimised. They are less frightening and seem less important or bizarre if their cause is understood. Furthermore, patients can learn techniques to alleviate or control many of the symptoms: there is a lot they can do to help themselves.

INDIVIDUAL SYMPTOMS, THEIR CAUSES AND HOW TO DEAL WITH THEM

Insomnia, nightmares, sleep disturbance. The sleep engendered by benzodiazepines, though it may seem refreshing at first, is not a normal sleep. Benzodiazepines inhibit both dreaming sleep (rapid eye movement sleep, REMS) and deep sleep (slow wave sleep, SWS). The extra sleep time that benzodiazepines provide is spent mainly in light sleep, termed Stage 2 sleep. REM and SWS are the two most important stages of sleep and are essential to health. Sleep deprivation studies show that any deficit is quickly made up by a rebound to above normal levels as soon as circumstances permit.

In regular benzodiazepine users REMS and SWS tend to return to pre-drug levels (because of tolerance) but the initial deficit remains. On withdrawal, even after years of benzodiazepine use, there is a marked rebound increase in REMS which also becomes more intense. As a result, dreams become more vivid, nightmares may occur and cause frequent awakenings during the night. This is a normal reaction to benzodiazepine withdrawal and, though unpleasant, it is a sign that recovery is beginning to take place. When the deficit of REMS is made up, usually after about 4-6 weeks, the nightmares become less frequent and gradually fade away.

Return of SWS seems to take longer after withdrawal, probably because anxiety levels are high, the brain is overactive and it is hard to relax completely. Subjects may have difficulty in getting off to sleep and may experience "restless legs syndrome", sudden muscle jerks (myoclonus) just as they are dropping off or be jolted suddenly by a hallucination of a loud bang (hypnagogic hallucination) which wakes them up again. These disturbances may also last for several weeks, sometimes months.

However, all these symptoms do settle in time. The need for sleep is so powerful that normal sleep will eventually reassert itself. Meanwhile, attention to sleep hygiene measures including avoiding tea, coffee, other stimulants or alcohol near bedtime, relaxation tapes, anxiety management techniques and physical exercise may be helpful. Taking all or most of the dose of benzodiazepine at night during the reduction period may also help. Occasionally another drug might be indicated (see section on adjuvant drugs, below).

Intrusive memories. A fascinating symptom in patients undergoing benzodiazepine withdrawal is that they often mention the occurrence of what seem to be intrusive memories. Their minds will suddenly conjure up a vivid memory of someone they have not thought about or seen for years. Sometimes the other person's face will appear when looking in the mirror. The memory seems uncalled for and may recur, intruding on other thoughts. The interesting thing about these memories is that they often start to occur at the same time that vivid dreams appear; these may be delayed until one or more weeks after the dosage tapering has started. Since recent sleep research indicates that certain stages of sleep (REMS and SWS) are important for memory functions, it is likely that the dreams and the memories are connected. In both cases the phenomena may herald the beginning of a return in normal memory functions and, although sometimes disturbing, can be welcomed as a sign of a step towards recovery.

Poor memory and concentration are also features of benzodiazepine withdrawal, and are probably due to continued effects of the drug. Mentors should be prepared to repeat encouragements again and again, week after week, as their words are soon forgotten.

Panic attacks. Panic attacks may appear for the first time during withdrawal, although some patients have long experience with this distressing symptom. The actress Glenda Jackson, who was not on benzodiazepines, described them as follows: "God, those panic attacks. You think you're dying; your heart pounds so strongly it feels like it's going to jump out of your chest; you choke and begin to feel you can't breathe - and all this is accompanied by terrible shaking and tremor, and feeling freezing cold" (Sunday Times Magazine p.15, October 17, 1999). These attacks are characteristic of some anxiety states and are the result of storms of central and peripheral nervous system hyperactivity, especially the centres normally concerned with fear and flight reactions in response to emergencies. The brain centres that control these fear reactions have been damped down by benzodiazepines and may rebound with renewed vigour as the benzodiazepines leave the body.

Distressing as they are, panic attacks are never fatal and usually last little more than 30 minutes. What is more, it is possible to learn to exercise control over them. Various approaches are described below. Learning to control a panic attack is a skill that improves with practice and needs to be worked on at home. However, panic attacks (and other withdrawal symptoms) have a knack of coming on at inappropriate moments away from home. In such circumstances it is important to stand your ground, resisting the impulse to run away. Dr Peter Tyrer suggests the following manoeuvre when a severe withdrawal symptom such as a panic attack comes on when you are pushing a trolley round a supermarket:

"Take much slower and deeper breaths, making sure that you get air deep down into the lungs instead of just at the top of the chest."

"As you do this you will find that your arms and hands relax so that the whites of your knuckles no longer show as you grip the supermarket trolley."

"Do not move on until you feel the tension flowing out of your hands. With each deep breath you should feel your tension flowing away and, as it does, your symptoms will lessen or disappear."

Peter Tyrer, How to Stop Taking Tranquillisers, Sheldon Press, London 1986, p.63.

The discovery that a panic attack can be controlled without resorting to a tablet is a great boost to self-confidence, and the development of new stress-coping strategies is often the key to successful benzodiazepine withdrawal. Panic attacks usually disappear within six weeks of withdrawal.

Generalised anxiety, panics and phobias. There are many non-pharmacological techniques for helping people with anxiety. Some of these are listed below, but it is beyond the scope of this booklet to give details of each technique or to mention all of them. None of them are essential for everybody coming off tranquillisers, but can be helpful for those having difficulty.

(1) Psychological techniques

Behaviour therapy

aims to replace anxiety-related behaviours with better adapted behaviours

Progressive muscular relaxation (reduces muscle tension and anxiety)

Diaphragmatic breathing (many anxious people hyperventilate)

Guided imaging (focus on pleasant, relaxing situations; relaxation tapes with music and calm words can also be used at home)

Controlled exposure to frightening situations, gradually increasing till anxiety diminishes

Cognitive-behavioural therapy

Teaches patients to understand their thinking patterns so that they can react differently to anxiety-provoking situations

Coping skills therapy/anxiety management (learning techniques) to avoid anxiety-provoking situations and to deal with anxiety (if it occurs)

Cognitive retraining skills

(2) Complementary medicine techniques

Acupuncture

Aromatherapy

Massage, reflexology

Homeopathy

(3) Exercise and other techniques

Sports - aerobics, jogging, swimming, "pilates", walking and anything active that you find enjoyable

Yoga - Many different types and techniques

Meditation - Many different types and techniques

The choice of, and response to, each of these measures depends very much on the individual. The various psychological techniques have been formally tested and give the best long-term results. However, the outcome depends largely on the skill of the therapist, including his/her knowledge of benzodiazepines, and the rapport between therapist and client.

Of the complementary medicine techniques, all can help with relaxation during the procedure but the effects tend to be short-lived. For example, patients in my clinic who underwent a course of 12 acupuncture sessions by an acupuncturist trained in both Chinese and Western acupuncture enjoyed and felt relaxed by the sessions but they did not do any better in the long run than others who did not have acupuncture.

Certain individuals respond very well to yoga and meditation techniques. One particular patient who was confined to a wheelchair with a spastic paralysis and who was also blind, was able to come off all his benzodiazepines with the help of a meditation technique. His spasticity actually improved. However, not everyone is able to devote the mental and physical concentration required for these techniques. Physical exercise, within your own limitations, is good for everyone.

On the whole, different approaches suit different individuals and need to be personalised. If you believe in a certain approach, it will probably do you good.

Sensory hypersensitivity. A characteristic feature of benzodiazepine withdrawal is a heightened sensitivity to all sensations - hearing, sight, touch, taste and smell. When extreme, these sensations can be disturbing. One lady had to stop all the clocks in the house because their ticking sounded unbearably loud; many have had to don dark glasses because ordinary light seemed dazzlingly bright. Some find that the skin and scalp becomes so sensitive that it feels as if insects are crawling over them. Heartbeats become audible and there may be a hissing or ringing sound in the ears (tinnitus - see below). Many people complain of a metallic taste in the mouth and several notice strange, unpleasant, smells which seem to emanate from the body. These sensations, including an unpleasant smell (which usually no-one else can detect) have been described in anxiety states in the absence of benzodiazepines. Like insomnia and panics, they are probably reflections of heightened activity in the central nervous system. Such hypervigilance is part of the normal fear and flight response which is damped down by benzodiazepines but undergoes a rebound during withdrawal.

These sensations return towards normal as withdrawal progresses, and some people are pleased with the new, seemingly extraordinary, clarity of their perceptions. Only in withdrawal do they realise how much their senses have been obscured by benzodiazepines. One lady described how thrilled she was when she could suddenly see individual blades of grass in her newly bright green lawn; it was like the lifting of a veil. Thus, these sensations need not give rise to fear; they can be viewed as signs of recovery.

Depersonalisation, derealisation. Feelings of depersonalisation and of unreality are associated with benzodiazepine withdrawal, although they also occur in anxiety states. They occur most often during over-rapid withdrawal from potent benzodiazepines and are, anecdotally, particularly marked on withdrawal from clonazepam (Klonopin). In these states, the person seems detached from his body and seems almost to be observing it from the outside. Similar experiences are described in near-death states when the individual feels that he is hovering above his body, detached from the events occurring below. They are also described by people involved in extreme emergencies and in individuals subjected to torture. They are clearly not specific to benzodiazepines.

Such experiences probably represent a normal defensive reaction evolved as a protection against intolerable suffering. They may involve a primitive brain mechanism similar to the "freezing" of some animals when presented with an inescapable danger. Like other benzodiazepine withdrawal symptoms, these feelings resolve in time and should not be interpreted as abnormal or crazy.

Hallucinations, illusions, perceptual distortions. The benzodiazepine withdrawal symptom that raises most fear of going mad is hallucination. Terrifying hallucinations have occurred in people undergoing rapid or abrupt withdrawal from high doses, but the reader can be reassured that they are exceedingly rare with slow dosage tapering as outlined in Chapter II. If hallucinations occur, they are usually visual - patients have described hallucinations of a large bat sitting on the shoulder, or the appearance of horns sprouting from a human head - but auditory, olfactory and tactile hallucinations can also occur. Somewhat less frightening are hallucinations of small creatures, usually insects, which may be associated with the sensations of insects crawling on the skin (similar hallucinations occur in cocaine and amphetamine withdrawal). Sometimes hallucinations merge with illusions and misperceptions. For example, a coat hanging on the door may give the illusion of being a person. Floors apparently tilting and walls that seem to slope inwards are perceptual distortions.

The mechanisms of these bizarre symptoms are probably similar to those which cause delirium tremens (hallucinations, classically of pink elephants or rats, in the "DTs" of alcohol withdrawal). As mentioned in Chapter I, benzodiazepines cause profound perturbations throughout the brain, and abrupt withdrawal may be accompanied by uncontrolled release of dopamine, serotonin and other neurotransmitters which cause hallucinations in psychotic disorders as well as in alcohol withdrawal and cocaine, amphetamine and LSD abuse.

Once the hallucinations, which seem real at the time, are recognised as "merely" hallucinations, they quickly become less alarming. They do not herald the onset of madness; they are simply instances of benzodiazepines playing tricks on the brain which will right itself in time. A good mentor can usually reassure and "talk down" a person suffering from benzodiazepine withdrawal-induced hallucinations. In any case they should not worry anyone undergoing slow withdrawal.

Depression, aggression, obsessions. Depressive symptoms are common both during long-term benzodiazepine use and in withdrawal. It is not surprising that some patients feel depressed considering the amalgam of other psychological and physical symptoms that may assail them. Sometimes the depression becomes severe enough to qualify as a "major depressive disorder", to use the psychiatric term. This disorder includes the risk of suicide and may require treatment with psychotherapy and/or antidepressant drugs.

Severe depression may result from biochemical changes in the brain induced by benzodiazepines. Benzodiazepines are known to decrease the activity of serotonin and norepinephrine (noradrenaline), neurotransmitters believed to be closely involved in depression. Antidepressant drugs including the selective serotonin reuptake inhibitors (SSRIs such as Prozac) are thought to act by increasing the activity of such neurotransmitters.

Depression in withdrawal may become protracted (see section on protracted symptoms) and if it does not lift within a few weeks and is unresponsive to simple reassurance and encouragement, it is worth seeking a medical opinion and possibly taking an antidepressant drug (see section on adjuvant medication). Depression in withdrawal responds to antidepressant drugs in the same way as depressive disorders where benzodiazepines are not involved. If, as in many cases, an antidepressant drug is already being taken along with the benzodiazepine, it is important to continue the antidepressant until after benzodiazepine withdrawal is complete. Withdrawal from the antidepressant can be considered separately at a later stage (See Chapter II, Schedule 13).

Aggressive disorders are also associated with low serotonin activity (among other factors) and the appearance of anger and irritability during benzodiazepine withdrawal may involve similar mechanisms as depression. However, these symptoms usually disappear spontaneously and do not last very long. Obsessive disorders (Obsessive Compulsive Disorder, OCD) also respond to SSRIs, suggesting a similar mechanism. Obsessive traits may be temporarily increased during withdrawal and seem to reflect a mixture of anxiety and depression. These tend to settle spontaneously as anxiety levels decline.

Muscle symptoms. Benzodiazepines are efficient muscle relaxants and are used clinically for spastic conditions ranging from spinal cord disease or injury to the excruciating muscle spasms of tetanus or rabies. It is therefore not surprising that their discontinuation after long-term use is associated with a rebound increase in muscle tension. This rebound accounts for many of the symptoms observed in benzodiazepine withdrawal. Muscle stiffness affecting the limbs, back, neck and jaw are commonly reported, and the constant muscle tension probably accounts for the muscle pains which have a similar distribution. Headaches are usually of the "tension headache" type, due to contraction of muscles at the back of the neck, scalp and forehead - often described as a "tight band around the head". Pain in the jaw and teeth is probably due to involuntary jaw clenching, which often occurs unconsciously during sleep.

At the same time, the nerves to the muscles are hyperexcitable, leading to tremor, tics, jerks, spasm and twitching, and jumping at the smallest stimulus. All this constant activity contributes to a feeling of fatigue and weakness ("jelly-legs"). In addition, the muscles, especially the small muscles of the eye, are not well co-ordinated, which may lead to blurred or double vision or even eyelid spasms (blepharospasm).

None of these symptoms is harmful, and they need not be a cause of worry once they are understood. The muscle pain and stiffness is actually little different from what is regarded as normal after an unaccustomed bout of exercise, and would be positively expected, even by a well-trained athlete, after running a marathon.

There are many measures that will alleviate these symptoms, such as muscle stretching exercises as taught in most gyms, moderate exercise, hot baths, massage and general relaxation exercises. Such measures may give only temporary relief at first, but if practised regularly can speed the recovery of normal muscle tone - which will eventually occur spontaneously.

Bodily sensations. All sorts of strange tinglings, pins and needles, patches of numbness, feelings of electric shocks, sensations of hot and cold, itching, and deep burning pain are not uncommon during benzodiazepine withdrawal. It is difficult to give an exact explanation for these sensations but, like motor nerves, the sensory nerves, along with their connections in the spinal cord and brain, become hyperexcitable during withdrawal. It is possible that sensory receptors in skin and muscle, and in the tissue sheaths around bones, may fire off impulses chaotically in response to stimuli that do not normally affect them.

In my clinic, nerve conduction studies in patients with such symptoms revealed nothing abnormal - for example, there was no evidence of peripheral neuritis. However, the symptoms were sometimes enough to puzzle neurologists. Three patients with a combination of numbness, muscle spasms and double vision were diagnosed as having multiple sclerosis. This diagnosis, and all the symptoms, disappeared soon after the patients stopped their benzodiazepines.

Thus these sensory symptoms, though disconcerting, are usually nothing to worry about. Very occasionally, they may persist (see section on protracted symptoms). Meanwhile, the same measures suggested under muscle symptoms (above) can do much to alleviate them, and they usually disappear after withdrawal.

Heart and lungs. Palpitations, pounding heart, rapid pulse, flushing, sweating, and breathlessness are usual accompaniments of panic attacks, but may occur without panics. They do not signify heart or lung disease but are simply the expression of an overactive autonomic nervous system. Slow deep breathing and relaxation, as described under panic attacks, can do much to control these symptoms. Do not worry about them: they would be accepted as normal if you were running for a bus, and will do no more harm than if you really were!

Problems with balance. Some people during benzodiazepine withdrawal report feeling unsteady on their feet; sometimes they feel they are being pushed to one side or feel giddy, as if things were going round and round. An important organ in controlling motor stability and maintaining equilibrium is a part of the brain called the cerebellum. This organ is densely packed with GABA and benzodiazepine receptors (See Chapter I) and is a prime site of action of benzodiazepines. Excessive doses of benzodiazepines, like alcohol, cause unsteadiness of gait, slurred speech and general incoordination, including inability to walk in a straight line. It may take some time for the cerebellar systems to restabilise after benzodiazepine withdrawal and the symptoms can last until this process is complete. Exercises, such as standing on one leg, first with eyes open, then with eyes closed, can speed recovery.

Digestive problems. Some people have no problems at all with their digestive systems during or after withdrawal, and may even notice that they are enjoying their food more. Others, perhaps more prone constitutionally, may complain of a range of symptoms associated with "irritable bowel syndrome" (IBS). These can include nausea, vomiting, diarrhoea, constipation, abdominal pain, flatulence, gaseous distension and heartburn. Quite a few have found these symptoms so uncomfortable that they have undergone hospital gastrointestinal investigations, but usually no abnormality is found. The symptoms may be partly due to overactivity in the autonomic nervous system, which controls the motility and secretions of the gut and is very reactive to stress, including the stress of benzodiazepine withdrawal. In addition, there are benzodiazepine receptors in the gut. It is not clear what the functions of these receptors are or how they are affected by benzodiazepines or benzodiazepine withdrawal, but alterations in these receptors may play some part in increasing gut irritability.

Considerable loss of weight (8-10lb or more) sometimes occurs in withdrawal. This may be due to a rebound effect on appetite, since benzodiazepines have been shown to increase appetite in animals. On the other hand, some people gain weight in withdrawal. In any case, weight changes are not severe enough to worry about and normal weight is soon regained after withdrawal. A few people have difficulty in swallowing food - the throat seems to tighten up especially if eating in company. This is usually a sign of anxiety and is well-known in anxiety states. Practising relaxation, eating alone, taking small well chewed mouthfuls with sips of liquid and not hurrying make things easier and the symptom settles as anxiety levels decline.

Most digestive symptoms get better after withdrawal but in a few people they persist and become a protracted symptom, raising fears of food allergy or candida infection. These questions are discussed further in the section on protracted symptoms.

Immune system. "Why do I get so many infections?" This question is commonly asked by patients withdrawing from benzodiazepines. They seem to be prone to colds, sinusitis, ear infections, cystitis, oral and vaginal thrush (candida), other fungal infections of the skin and nails, cracked lips, mouth ulcers and influenza. Also common are complaints of adverse reactions to antibiotics used to treat some of the bacterial infections.

It is not clear whether there really is an increased incidence of infections in people undergoing benzodiazepine withdrawal, because there have been no comparisons with otherwise similar populations who have not been exposed to benzodiazepines. However, many factors affect the immune system. One of these is stress, with increased output of the stress hormone, cortisol, which inhibits immune responses. Another factor is depression, also related to stress and associated with increased cortisol secretion. Increased cortisol levels can reduce resistance to infection and also cause flare-ups of incipient infection. Benzodiazepine withdrawal can clearly be stressful but, strangely, in patients that I have tested, blood cortisol concentrations have been low. So this subject remains a mystery and probably merits further research. The message for people undergoing benzodiazepine withdrawal is to try to lead a healthy lifestyle, which includes a balanced diet, plenty of exercise and rest, and avoidance of extra stress where possible. Slow dosage tapering (Chapter II) is the best way to reduce the stress of withdrawal.

Endocrine problems. Benzodiazepines undoubtedly have effects on the endocrine system, but these have not been closely studied in humans, either during long-term benzodiazepine use or in withdrawal. Many women complain of menstrual problems but these are common in the general population and there is no clear evidence that they are directly attributable to benzodiazepines. A proportion of female long-term benzodiazepine users have had hysterectomies, but again there is no evidence of a direct link with benzodiazepine use. Occasionally both men and women on benzodiazepines complain of breast swelling or engorgement and it is possible that benzodiazepines affect secretion of the hormone prolactin. Endocrine symptoms that are due to benzodiazepines improve after withdrawal.

Fits, convulsions. Benzodiazepines are potent anticonvulsants. They can be life-saving in status epilepticus (repeated fits, one after another) and in fits caused by overdose of certain drugs (for example, tricyclic antidepressants). However, rapid withdrawal, especially from high potency benzodiazepines, can precipitate epileptic fits as a rebound reaction. Such an occurrence is extremely rare with slowly eliminated benzodiazepines (e.g. diazepam) or with slow dosage tapering. If a fit does occur in these circumstances, it is usually only a single fit and causes no lasting damage. Other phenomena seen in rapid withdrawal are psychotic symptoms, severe confusion and delirium, but again these hardly ever occur with slow dosage tapering. By following the withdrawal schedules outlined in Chapter II, you can be confident of avoiding these complications.

EXTRA MEDICATION DURING BENZODIAZEPINE WITHDRAWAL

"Is there any medication I can take to help me through withdrawal?" This question is sometimes asked by people embarking on a benzodiazepine tapering program. In contrast, others are so against drugs when they decide on withdrawal that they are loth to take anything, even the simplest pain killer. The answer to the first question is that there is no medication which will substitute for a benzodiazepine, unless it is another benzodiazepine, or a drug with benzodiazepine-like properties (such as barbiturates or zolpidem [Ambien]). All such drugs should be avoided as they only substitute one type of dependence for another. (There is a method, advocated by some US doctors, in which phenobarbitone, a long-acting barbiturate, is substituted for a benzodiazepine and then slowly withdrawn, but this method has no particular advantages over tapering directly from a long-acting benzodiazepine).

However, there are some drugs which may help to control particular symptoms in withdrawal and which deserve consideration in certain situations though not recommended for routine use. Usually they will only be required temporarily, but they can sometimes ease a difficult situation and enable the user to proceed with the withdrawal program.

Antidepressants. Antidepressants are the most important adjuvant drugs to consider in withdrawal. As mentioned before, depression can be a real problem in withdrawal and can sometimes be severe enough to pose a risk of suicide, though this is unusual with slow tapering. Like any other depression, the depression in withdrawal responds to antidepressant drugs and is probably caused by the same chemical changes in the brain. Both the "old fashioned" tricyclic antidepressants (doxepin [sinequan], amitriptyline [Elavil]) and the selective serotonin reuptake inhibitors (SSRIs; fluoxetine [Prozac], paroxetine [Paxil]) can be effective and an antidepressant drug may be indicated if depression is severe. There is a school of thought, mainly amongst ex-tranquilliser users, that is opposed to the taking of any other drugs during withdrawal. But suicides have occurred in several reported clinical trials of benzodiazepine withdrawal. If depression is severe during benzodiazepine withdrawal as in any other situation, it seems foolhardy to leave it untreated.

There are, however, some disadvantages with antidepressants. One is that they take 2-3 weeks or more to become really effective. This means that the patient, and his/her mentor, must be on the look-out for depression so that treatment, if advised by the doctor, can start early. The second drawback is that anxiety may be temporarily worsened at the start of treatment either with tricyclics or SSRIs. This is a particular risk during benzodiazepine withdrawal when anxiety levels are usually high. To avoid aggravation of anxiety, it is important to start with the lowest possible dose of an antidepressant and then work up slowly, over two or three weeks. Do not be persuaded by your doctor to start immediately on the "therapeutic" dose for depression. There are also fears that antidepressants such as Prozac may in some patients induce an agitated, violent or suicidal state at the start of treatment; low initial dosage and careful monitoring may avoid this risk.

It is usually possible to continue with slow benzodiazepine tapering while starting on an antidepressant, although some may prefer to halt their programme for 2-3 weeks until the antidepressant has "taken hold" (but increasing the benzodiazepine dose should be strenuously avoided). Antidepressants not only alleviate depression but also, after 2-3 weeks, have anti-anxiety effects. They are in fact a better long-term treatment than benzodiazepines for anxiety, panic and phobic disorders, and may in some cases actively help the benzodiazepine withdrawal process.

Once started on an antidepressant for depression, the treatment should be continued for some months (usually about 6 months) to avoid recurrence of the depression. Benzodiazepine tapering can continue during this time, and the antidepressant will sometimes act as a welcome umbrella during the last stages of withdrawal. It is important to finish the benzodiazepine withdrawal before starting to withdraw the antidepressant. Quite often, people taking long-term benzodiazepines are already taking an antidepressant as well. In this case they should stay on the antidepressant until the benzodiazepine withdrawal is complete.

Another drawback of antidepressants is that they, too, cause withdrawal reactions if they are stopped suddenly, a fact which has not always been appreciated by doctors. Antidepressant withdrawal symptoms include increased anxiety, sleep difficulties, influenza-like symptoms, gastrointestinal symptoms, irritability and tearfulness - not much different, in fact, from benzodiazepine withdrawal symptoms. These reactions can be prevented by slow tapering of the antidepressant dosage over about 1-3 months (See Table 2). Most people who have withdrawn from benzodiazepines will be experts at tapering dosages when the time comes to stop the antidepressant and will be able to work out a rate of withdrawal that suits them.

Apart from their therapeutic effects in depression and anxiety, some antidepressants have a sedative effect which patients who are particularly plagued with insomnia have found helpful. Low doses (10-50mg) of amitriptyline (Elavil) or doxepin (Sinequan) are remarkably effective in promoting sleep if taken at bed-time. These can be taken for short periods of a few weeks and stopped by reducing the dosage stepwise or taking the drug every other night. Withdrawal is not a problem when small doses are taken for short periods or intermittently.

Beta-blockers. In a few cases, severe palpitations, muscle tremors or motor jerks develop during benzodiazepine withdrawal and hinder progress. These symptoms can be controlled or ameliorated by beta-blocking drugs such as propranolol (Inderal). Drugs of this type inhibit the effects of excess epinephrine and norepinephrine (adrenaline and noradrenaline) released by an overactive sympathetic nervous system. They slow the heart and prevent excess muscle activity. Although they have little effect on psychological symptoms, they can cut the vicious circle in which palpitations or tremor create anxiety which leads to yet more palpitations. Some people in benzodiazepine withdrawal take small doses of these drugs (10-20mg Inderal three times daily) regularly, while others reserve them to take only if the physical symptoms of a panic attack seem uncontrollable. They are not a cure, but can sometimes help people through a difficult situation. In larger doses, beta-blockers are used for raised blood pressure and angina, but such doses are not advised in benzodiazepine withdrawal. They should not be taken by anyone who has asthma as they can cause constriction of the bronchial tubes. If beta-blockers have been used regularly for any length of time, they should be withdrawn slowly by tapering the dosage, as they too can cause a withdrawal reaction of increased heart rate and palpitations.

Hypnotics and sedatives. Most other hypnotics and sedatives act in a similar way to benzodiazepines, including barbiturates, chloral derivatives (Noctec), ethchlorvynol (Placidyl), zopiclone (Zimovane, Imovane), zolpidem (Ambien), zaleplon (Sonata) and, incidentally, alcohol. None of these drugs should be used as alternative sleeping pills or sleeping draughts during benzodiazepine withdrawal. All can cause a similar type of dependence and some are more toxic than benzodiazepines.

If sleep is really a problem, a small dose of a tricyclic antidepressant with sedative effects (see antidepressants, above) is a possible option. Alternatively, an antihistamine with sedative effects (e.g. diphenylhydramine [benadryl], promethazine [Phenergan]) may be used temporarily. Neither antidepressants nor antihistamines act by the same mechanisms as benzodiazepines.

Some drugs related to major tranquillisers have sedative effects and are also used for nausea, vertigo and motion sickness. These are sometimes prescribed during withdrawal, especially prochlorperazine (Compazine). However, such drugs can have serious side effects (motor disorders like Parkinson's disease) and are not recommended for long-term use or as a substitute for benzodiazepines.

Other drugs. Several other drugs have been tested in clinical trials of benzodiazepine withdrawal to see if they could speed the process, prevent or alleviate withdrawal symptoms, or improve the long-term success rate. Many of these trials have involved what is considered here as over-rapid withdrawal. For example, a recent US study of benzodiazepine withdrawal in long-term users (Rickels, Schweizer et al. Psychopharmacology 141,1-5,1999) tested the effects of a sedative antidepressant (trazodone, Desyrel) and an anticonvulsant drug (sodium valproate, Depakote). Neither drug had any effect on the severity of withdrawal symptoms, but the rate of taper was 25% of the benzodiazepine dose each week - a rather fast withdrawal! Other drugs which have been found to be of little or no value in withdrawal trials over 4-6 weeks include buspirone (BuSpar, an anti-anxiety drug), carbamazepine (Tegretol, an anticonvulsant), clonidine (Catapres, an anti-anxiety drug sometimes used in alcohol detoxification), nifedipine (Adalat) and alpidem.

There have been some reports that gabapentin (Neurontin), tiagabine (Gabitril) and possibly pregabalin (yet to be licensed) help with sleep and anxiety in withdrawal. However, there have been no controlled trials and it is not clear whether these drugs themselves cause withdrawal effects. In practice additional drugs are seldom needed with very slow benzodiazepine tapering. Only in special situations there might be a place for an antidepressant, beta blocker, sedative antihistamine or anticonvulsant. There is no need to avoid ordinary pain killers such as Tylenol, Feldene etc. for everyday aches and pains.

BENZODIAZEPINE USE DURING AND AFTER WITHDRAWAL

What happens if someone who is in the course of benzodiazepine withdrawal or has successfully withdrawn needs a surgical operation? Benzodiazepines are of value as premedication before major operations and for sedation and amnesia during minor surgical procedures. Yet many ex-users are terrified that if they are given a benzodiazepine for these purposes they will become dependent all over again. They can be reassured: a single dose of a benzodiazepine given for an operation does not bring back the addiction, although the stress of an operation may re-awaken the anxiety symptoms experienced during benzodiazepine withdrawal. Symptoms reported under these circumstances have usually been the result of fear. Many personally observed patients have had repeated doses of midazolam (Versed, Hypnovel), a short-acting benzodiazepine, for dental procedures (dental phobia is common in withdrawal), and other benzodiazepines including diazepam for major and minor surgery and have recovered without complications.

Also, people who have gone back on benzodiazepines, having failed at the first attempt at withdrawal, can be just as successful at tapering as first-timers.

DIET, FLUIDS AND EXERCISE

There has been increasing interest in the question of diet in benzodiazepine withdrawal, particularly in North America. What food/drinks should be excluded? What supplements should be added? These are frequent questions. In my opinion there is no need to be over-obsessive about diet. Some people advise that caffeine and alcohol should be completely ruled out. However, the point about gradual dosage tapering at home is that people should get used to living a normal lifestyle without drugs. In my experience, coffee or tea in moderation (about two cups a day), or reasonable amounts of cocoa, chocolate or coca cola, are perfectly compatible with benzodiazepine withdrawal - except in the few individuals who are exquisitely sensitive to caffeine or those with very high anxiety levels. Clearly one should not take caffeine late in the evening or drink cups of tea/coffee (unless decaffeinated) in the middle of the night if insomniac, but to prohibit a cup of tea/coffee at breakfast is in general unduly restrictive. One is, after all, striving to be normal and sociable, not fussy.

Similarly with alcohol: a glass or two of wine is perfectly permissible (and even said by some to be advisable for health). Although it is important not to substitute increasing doses of alcohol for decreasing doses of benzodiazepines, there is no need to deny oneself small pleasures. Moderation is the key: there is no call to be puritanical.

The same principles apply to food. Humans are singularly well adapted through evolution to obtain the nutrients they need from a wide variety of diets and to eliminate unwanted products. A normal healthy diet which includes generous amounts of fruit and vegetables and a source of protein and fats (from meat or vegetables), and not too much pure sugar or "junk foods", provides all the nutrients a person needs. There is no general need for dietary supplements or extra vitamins or minerals or for "detoxifying" measures. All these can be harmful in excess. Advice to cut out white flour, white sugar etc. may help certain individuals but I have also observed that overly restrictive diets can have adverse effects. Some people say they have felt much better after going on a particular diet - this makes one wonder what sort of diet they were eating before!

Individuals may find they are intolerant of certain foods although this is not usually a true allergy. In this case, let common sense prevail and avoid such foods for a while. If in doubt, get the advice of a reliable and unbiased nutritionist, but in general stick to a normal healthy diet without food fads. Before diets became "fashionable" thousands of people successfully came off their benzodiazepines in many different countries with widely varying dietary habits without restriction - and this continues today.

A normal diet includes a normal amount of fluid consumption. Requirements for water and salt vary with body size, environmental temperature, amount of exercise, etc. so cannot be stated categorically. However, there is no need to drink extra amounts of fluid during withdrawal with the idea of "flushing out impurities/toxins". The body is very good at doing this, even at minimal fluid consumption, and surplus water is simply excreted.

Regular moderate exercise is recommended during withdrawal as it maintains general fitness, builds up stamina, increases the circulation to brain, muscle and skin and improves mood, but there is no point in slavishly doing exercises that you hate. The aim is to lead a healthy lifestyle which by definition includes some exercise in a form that is enjoyable for you.

Smoking. I hardly dare to mention smoking in view of present day attitudes to this unfortunate addiction, but for those who are smokers it is probably asking too much to attempt to stop smoking and withdraw benzodiazepines at the same time. Many people have found that giving up smoking is easier when they are off benzodiazepines, when the desire for nicotine may even wane somewhat. In general, excessive worrying over your undesirable habits (or your diet) can add to the stress of withdrawal. It is better to relax a bit and be gentle with yourself.

COURSE OF WITHDRAWAL

During benzodiazepine withdrawal, symptoms characteristically wax and wane, varying in severity and type from day to day, week to week, and even during the course of a day. Some symptoms come and go; others may take their place. There is no need to be discouraged by these wave-like recurrences; the waves become less severe and less frequent as time passes. Typically "Windows" of normality, when you feel positively well for a few hours or days, appear after some weeks; gradually the "Windows" become more frequent and last longer, while any intervening discomfort ebbs away.

It is impossible to give an exact time for the duration of withdrawal symptoms. It depends on where you start from, how much support you need and receive, how you manage your taper and many other factors. With slow tapering, some long-term users have virtually lost all their symptoms by the time they take their last tablet, and in the majority symptoms disappear within a few months. Vulnerability to extra stress may last somewhat longer and a severe stress may - temporarily - bring back some symptoms. Whatever your symptoms, it is best not to dwell on them. Symptoms are just symptoms after all and most of them in withdrawal are not signs of illness but signals of recovery. Furthermore, as your mind clears, you can work out more and more effective ways to deal with them so that they become less significant.

One reassuring finding from many clinical studies is that eventual success in withdrawal is not affected by duration of use, dosage or type of benzodiazepine, rate of withdrawal, severity of symptoms, psychiatric diagnosis, or previous attempts at withdrawal. Thus from almost any starting point, the motivated long-term user can proceed in good heart.

PROTRACTED WITHDRAWAL SYMPTOMS

A minority of people who have withdrawn from benzodiazepines seem to suffer long-term effects - protracted symptoms that just don't go away after months or even years. It has been estimated that perhaps 10-15 per cent of long-term benzodiazepine users develop a "post-withdrawal syndrome". Many of these people have taken benzodiazepines for 20 years or more and/or have had bad experiences in withdrawal. The incidence of protracted symptoms in those who have undergone a slow taper under their own control is almost certainly very much lower.

Table 3 shows the symptoms most likely to be long-lasting. These include anxiety, insomnia, depression, various sensory and motor symptoms, gastrointestinal disturbances, and poor memory and cognition. The reasons why these symptoms persist in some people are not clear. Probably many factors are involved, some directly due to the drug and some to indirect or secondary effects (See Table 4).

Anxiety - Gradually diminishing over a year

Depression - May last a few months; responds to antidepressant drugs

Insomnia - Gradually diminishing over 6-12 months

Sensory symptoms: tinnitus, tingling, numbness, deep or burning pain in limbs, feeling of inner trembling or vibration, strange skin sensations - Gradually receding but may last at least a year and occasionally several years

Motor symptoms: muscle pain, weakness, painful cramps, tremor, jerks, spasms, shaking attacks - Gradually receding but may last at least a year and occasionally several years

Poor memory and cognition - Gradually receding but may last at least a year and occasionally several years

Gastrointestinal symptoms - Gradually improving but may last a year and occasionally several years

TABLE 4. SOME POSSIBLE CAUSES OF PROTRACTED BENZODIAZEPINE WITHDRAWAL SYMPTOMS

Possible mechanisms

Effects

1. Learning of stress-coping strategies blocked by benzodiazepine use exposed on withdrawal Anxiety, vulnerability to stress

2. Impairment of memory caused by benzodiazepines prevents normal resolution of distressing life events which are exposed on withdrawal Anxiety, depression

3. Traumatic experiences during previous withdrawal Post-traumatic stress symptoms

4. (?) Biochemical alterations caused by benzodiazepines (serotonin, norepinephrine [noradrenaline], stress hormones) Depression

5. Nervous system hyperexcitability due to persisting changes in GABA/benzodiazepine receptors Sensory and motor symptoms, anxiety, insomnia

6. (?) Structural or functional damage to brain tissue Poor memory and cognition

7. (?) Changes in gut and immune systems Gastrointestinal symptoms

8. (?) Long-term retention of benzodiazepines in tissues of the body Prolongs nervous system hyperexcitability

(?) indicates possible mechanisms for which at present there is no scientific evidence

Anxiety. Anxiety persisting after the acute phase of withdrawal may be partly due to the uncovering of a learning defect caused by the benzodiazepines. These drugs specifically impair the learning of new skills, including stress-coping strategies. Such skills are normally acquired continuously from childhood to middle age or later as experience of life accumulates. Their development may be blocked for a period of years during which benzodiazepines are taken. After withdrawal the ex-user is left in a vulnerable state with a decreased ability to deal with stressful situations. Full recovery may require many months of learning new stress-coping strategies to replace the years when this facility was blanketed by pills.

Secondly, benzodiazepine withdrawal may uncover life problems that have never been fully addressed. For example, the impairment of memory caused by benzodiazepines may prevent the normal resolution of personal stresses such as bereavement or a car crash. Such buried or half-forgotten experiences may have to be faced after withdrawal and may prolong both anxiety and depression. It is not uncommon for a widow or widower, first prescribed benzodiazepines on the death of the spouse, to go through the grieving process for the first time after withdrawal, even though the bereavement had occurred many years previously.

A third factor may operate in people who have had frightening experiences during withdrawal. This is not uncommon in those who have undergone rapid withdrawal without adequate explanation, often in hospital or detoxification centres but sometimes at home when their doctor has withdrawn prescriptions. Such people may develop symptoms of post-traumatic stress disorder (PTSD) in which their experiences are constantly repeated as flashbacks or nightmares and so prolong the anxiety.

In addition, many (though by no means all) long-term benzodiazepine users are constitutionally highly strung, sensitive people with relatively low self-esteem, whose anxiety problems have led to the prescription of benzodiazepines in the first place and whose continuing anxiety (possibly heightened by the benzodiazepines) has prompted the doctor to go on prescribing the drugs. It may take a long time for these people to regain, or attain, full confidence in themselves.

Despite these factors, protracted anxiety symptoms, including agoraphobia and panics, do tend to subside gradually and rarely last more than a year. The process may be hastened by good psychological support and by the measures described under acute anxiety symptoms. Believe it or not, people often feel more self-confident after withdrawal than they did before starting to take benzodiazepines.

Depression. Depression may be caused or aggravated by chronic benzodiazepine use, but is also a feature of the withdrawal syndrome. Depressive symptoms may appear for the first time after withdrawal, sometimes after a delay of a few weeks, and it can be severe and protracted for some months. It is not clear whether people who have had depression before, or have a family history of depression, are more prone to this complication, and its causes are not understood. As discussed in Chapters I and II, benzodiazepines disrupt the function of many neurotransmitters and hormones and depression could be the result, for example, of low serotonin activity combined with the stress of withdrawal. If severe enough to require definitive treatment, the depression in withdrawal responds to antidepressant drugs and/or cognitive therapy and usually diminishes gradually over 6-12 months.

Insomnia. Poor sleep is a common accompaniment of both anxiety and depression. In anxiety there is typically a difficulty in falling asleep, while depression is associated with early morning waking as well as frequent wakings during the night. Insomnia is also common as an acute withdrawal symptom along with nightmares and other sleep disturbances. Occasionally, however, insomnia (sometimes with "restless legs" and muscle jerks) persists as an isolated symptom after other symptoms have disappeared, and may last for many months. However, poor sleepers can be reassured that an adequate sleep pattern does return at last. There are powerful natural mechanisms in the body which ensure that the brain does not become severely sleep-deprived.

Sensory and motor disturbances. There is no doubt that benzodiazepine withdrawal leaves in its wake a nervous system that is exquisitely sensitive to all sensory and motor stimuli. Usually this state settles in a few weeks but occasionally disturbing sensations persist.

One of the most distressing sensory symptoms is tinnitus, a constant ringing or hissing in the ears which has been noted in several studies of benzodiazepine withdrawal. One lady described her tinnitus as a "needle of sound" piercing deep inside her head. Tinnitus is often associated with a degree of hearing loss and is not uncommon in people with partial nerve deafness who have never taken benzodiazepines. Nevertheless, it often makes its first appearance during benzodiazepine withdrawal in people who have had hearing loss for years. Also, it may be unilateral or precisely localised, even in those with symmetrical bilateral hearing loss. Whether people who have taken long-term benzodiazepines are particularly prone to tinnitus and if so why, is not known. It can persist for years and does not always respond to the usual treatments for tinnitus (maskers, etc); nor is it always relieved by restarting benzodiazepines. However, people with persisting tinnitus after withdrawal should seek the advice of a hearing specialist and may be lucky enough to find a clinic which specialises in this symptom.

A number of unpleasant bodily sensations may persist after withdrawal including tingling, "pins and needles" or patches of numbness in the trunk, face, limbs and fingers. These may be accompanied by burning pain or aches that sometimes seem to originate deep in the muscles or bones. Some people complain of an "inner trembling" or a sense of vibration, and some have described bizarre sensations as of water or slime running over the body or a serpent-like writhing on the scalp. Motor symptoms that may persist include muscle tension, weakness, cramps, jerks, spasms.

Hi Admin..

Would it be possible to stick this to the board for folk, so they can check it out and put their mind at ease, i know I'll be checking it from time to time.

Thank you.
