Medical uses

It is also occasionally used for agoraphobia, generalized anxiety disorder, premenstrual dysphoric disorder and menopausal hot flashes. Depression
A variety of meta analyses have been conducted to evaluate the efficacy of paroxetine in depression. They have variously concluded that paroxetine is superior or equivalent to placebo and that it is equivalent or inferior to other antidepressants. Despite this, there was no clear evidence that paroxetine was better or worse compared with other antidepressants at increasing response to treatment at any point in time. Anxiety disorders

Several studies have concluded that paroxetine is superior to placebo in the treatment of panic disorder.Paroxetine has demonstrated efficacy for the treatment of social anxiety disorder in adults and children. It is also beneficial for people with co-occurring social anxiety disorder and alcohol use disorder.

Comparative efficacy of paroxetine is equivalent to that of clomipramine and venlafaxine.
