the last one didn't work (celexa). I cheked with BB and she said suicide is a fairly common side effect of some drugs used to treat depression.
It has been suggested that SSRIs may cause depression to worsen and even lead to suicide in a small number of patients. These potential side effects are difficult to evaluate in depressed patients because depression can progress with or without treatment, and suicide is itself a consequence of depression. Moreover, the evidence supporting these potential side effects is weak. Therefore, no conclusions can yet be drawn about the relationship between SSRIs and worsening depression and suicide. Until better information is available, patients receiving SSRIs should be monitored for worsening depression and suicidal tendencies. from http://www.medicinenet.com/citalopram/article.htm
