What is Topamax?

Topamax (topiramate) is a prescription drug approved for use in the United States to treat both epilepsy and severe migraine headaches. An off-label use for Topamax is as a weight loss treatment.

Who takes it, and for what condition?

People with epilepsy who have certain types of seizures may use Topamax as a FDA-approved anticonvulsant medication prescribed to be taken alone or with other medications. Topamax is also FDA-approved for use to prevent migraine headaches, but not to relieve the pain of migraine headaches when they occur. From January 2007 through December 2010, approximately 32.3 million topiramate prescriptions were dispensed and approximately 4.3 million patients filled topiramate prescriptions from the outpatient retail pharmacies in the U.S.

Topamax and Birth Defects

On March 4, 2011, the FDA announced that, based on new data from the NAAED Pregnancy Registry, Topamax will be reclassified from a Pregnancy Category C to a Category D. The new data suggests that babies exposed to Topamax during the first trimester of pregnancy have a significant increased risk of cleft lip and cleft palate, as well as genital deformities and other fetal or skeletal malformations. These findings follow a 2008 study by the medical journal Neurology that reported similar findings linking Topamax to an unusually high rate of serious birth defects like oral clefts.

We are currently reviewing cases involving women who took Topamax® or one of its generic versions while in their first trimester of pregnancy and had a baby born with an oral cleft lip and/or cleft palate or serious fetal or skeletal malformations.
