Potential SSRI/SNRI and benzodiazepine withdrawal symptom list

Psychiatric drug withdrawal
Psychiatric drug withdrawal

The SSRI/SNRI symptoms are originally from this website on Effexor withdrawal.

I thought after this list I would also put a benzo withdrawal symptom list. Unfortunately there has not been enough study of other psychotropic drug classes to come up with comprehensive lists, though in my experience in all my groups I’ve seen there is a lot of crossover among all psychiatric drugs even when they have different methods of action. This is, most likely, due to the fact that they all effect the autonomic nervous system.

Certainly mood stabilizers and antipsychotics have all sort of similar issues and the withdrawal syndromes also can look quite similar.

I made a list last year of my symptoms but I did not look at these lists. Might be interesting to compare and contrast. I imagine I left stuff out. Here was my list which I’ve not revisited at this time. (my list got longer and more complicated later in the process: here they are revisited later)
