Fluoroquinolones can definitely make things worse for people in benzo wd. I had 2 doses of Cipro in the middle of my first CT withdrawal and it really worsened my situation and led to me being put on a stronger benzo after 4 months of intensified symptoms. I think it is probably a factor in my severe protracted wd, I just don't know how much of a factor. I know it felt like it was causing the same damage as benzos, only much faster.
