Midwest:
That is wonderful news that your prescriber is willing to prescribe an FDA-approved oral solution of diazepam!
Like everyone else here on BenzoBuddies, I am not an expert - just a peer trying my best to support other peers on this difficult journey.
What I can share is that, after considerable reading and research, if I had the option of using an FDA-approved oral solution of my benzodiazepine (unfortunately, one for mine is not available in the US), that’s what I would do.
Re: your question about dividing your doses ...
You’ve indicated in your signature that you are currently at 10mg valium (2mg morning & 8mg night). If this has been working for you, then if I were you, I’d keep to that split at least to begin. One of the advantages of using an oral solution is that you can make small reductions in one or both of these doses. It’s totally up to you to determine what works best for you - let your withdrawal symptoms be your guide.
Have you decided what taper rate you want to follow?
Are you comfortable with using an oral syringe to measure your doses?
Oops! I forgot to add ...
You and your pdoc can look up the drug information pamphlets from the different manufacturers of a diazepam oral solution at:
DailyMed
https://dailymed.nlm.nih.gov/dailymed/Just enter “diazepam” in the search box. When the new page opens, look for the entries that have the word “solution” in them (there are also injections and, of course, regular tablets). Most of the manufacturers make both a 5mg/5mL solution and an Intensol (concentrate). For tapering purposes, the former (lower concentration) is preferable.
