There have been several studies looking at the effects of Paxil CR for a variety of conditions.
Studies have shown Paxil CR to be effective for depression treatment in adults. In these studies, people taking it had more improvement in their depression symptoms than people who were not taking the medication. Also, long-term studies have shown that Paxil CR can help prevent relapse (or a return of depression symptoms).
Several studies have looked at using Paxil CR to treat adults with panic disorder. In these studies, people taking it had fewer panic attacks and less severe panic attacks when compared to people not taking the medicine. Also, in long-term studies, Paxil CR helped to prevent panic attacks from coming back.
Social Anxiety Disorder
Short-term studies have shown that Paxil CR is effective at treating social anxiety disorder in adults. In these studies, up to 64 percent of people taking Paxil CR felt that their social anxiety symptoms were "very much improved" or "much improved," compared to only 34.7 percent of those not taking the drug.
Premenstrual Dysphoric Disorder (PMDD)
Paxil CR was studied in three clinical trials for PMDD. Two studies looked at using it every day for PMDD treatment. These two studies did not include women who were on oral contraceptives (birth control pills). The third study looked at using Paxil CR only for the last two weeks of the menstrual cycle. All three studies showed Paxil CR to be effective for treating PMDD.
