any psychiatric drug can cause problems if it is misprescribed. for example, if you give an antidepressant to someone with bipolar disorder, it can wreak havoc.
however, the problem is not necessarily the fault of the drug.
also, many psychotics and sociopaths have probably been put on antidepressants at some point. if they kill someone, does that mean the drug made them do it?
overall, these drugs have saved many lives. however, trial lawyers dont't care about that.
