What is Zofran?

Zofran (ondansetron) is a powerful anti-nausea drug manufactured by GlaxoSmithKline. It was approved by the FDA in 1991 to help cancer patients with the severe nausea and vomiting side effects of chemotherapy and radiation treatments. It also was approved to prevent and treat nausea and vomiting after surgery. GSK never conducted randomized controlled research studies to investigate the drug’s possible side effects in pregnant women. Zofran has never been approved by the FDA for use by pregnant women to treat morning sickness.

How Does Zofran Work?

Zofran works by blocking serotonin receptors in the brain and gut to prevent nausea messages from being sent to the part of the brain that initiates and controls the act of vomiting. When taken by pregnant women, it crosses the placenta barrier and is exposed to the fetus.

Generic Zofran

The GSK patent on Zofran expired in December 2006 and ondansetron, the generic version, began to be sold in the U.S..

Zofran for Morning Sickness?

Most pregnant women suffer nausea and vomiting (“morning sickness”) during the first trimester of pregnancy. Extreme morning sickness, called hypermemisis gravidarum, affects about 1% of pregnancies.

Zofran has never been approved by the FDA for use by pregnant women to treat morning sickness. Nonetheless, lawsuits claim GSK marketed Zofran “off label” as a safe and effective treatment for morning sickness. About a million pregnant women each year in the U.S. take the drug to treat morning sickness and nausea.

Zofran Settlement

In 2012, GlaxoSmithKline reached a $3 billion settlement agreement with the government regarding the marketing of several drugs including Zofran.

GSK’s agreement with the U.S. Department of Justice settled claims that GlaxoSmithKline:

    (a) “promoted the sale and use of Zofran for a variety of conditions other than those for which its use was approved as safe and effective by the FDA (including hyperemesis and pregnancy-related nausea)”

    (b) “made and/or disseminated unsubstantiated and false representations about the safety and efficacy of Zofran concerning the uses described in subsection (a) [hyperemesis and pregnancy-related nausea]”

    (c) “offered and paid illegal remuneration to health care professionals to induce them to promote and prescribe Zofran”
