GlaxoSmithKline (GSK), the manufacture of Paxil, has agreed to settlements in nearly 200 individual cases alleging that the antidepressant caused birth defects. Most of the cases alleged that babies born to mothers taking Paxil suffered from heart defects. The Food and Drug Administration warned doctors about a study showing that babies born to women who took Paxil during the first trimester of pregnancy had a higher rate of major birth defects. The terms of the recent settlement are confidential. At least 600 cases have been filed alleging that Paxil is responsible for congenital birth defects. Up to 100 other cases have already settled. GSK has also paid approximately $1 billion in settlements of Paxil-related cases not involving birth defects. The drug is used to treat a wide variety of psychological maladies, including depression, anxiety, and obsessive-compulsive disorder.
