Are you looking to file a Zofran lawsuit? If your child suffered a birth defect as a result of taking Zofran you are not alone. A Zofran lawsuit lawyer may be able to help advise you of the legal options you may have. Zofran, or Ondansetron, is a drug that was marketed as an antiemetic (anti-nausea) used to treat the side effects of cancer chemotherapy, radiation therapy, and surgery. In the last decade, however, Zofran has become the most commonly prescribed antiemetic for pregnant women, despite the fact that it has never been approved for such use nor its safety established. In fact, the only FDA-approved drug for treating nausea and vomiting in pregnancy is one called Diclegis (generic name: doxylamine/pyridoxine).
