Due to documented incidences of violent and suicidal behaviors in persons taking the antidepressant drug Effexor, Wyeth, the drug's manufacturer, along with the recommendation of the U.S. Food & Drug Administration, has now issued warnings regarding these potential side effects of the drug. There were also reports of increased deaths in patients with coronary artery disease who were also taking Effexor. However, many people reportedly suffered such side effects from taking Effexor by prescription, long before any such warnings became public. As a result, a variety of lawsuits have been filed against Wyeth for failure to adequately warn of Effexor's side effects, as well as allegedly dishonest marketing about Effexor's success rates. Since Effexor is Wyeth's biggest selling drug, it is likely that there are many people whose Effexor use resulted in unwanted and unanticipated side effects. Therefore, if you or a loved one has experienced such side effects from taking Effexor, you should be sure to contact an attorney with expertise in products liability litigation.
