Ten-Year Study Confirms Topamax Birth Defects

On Behalf of | Aug 22, 2012 | Dangerous Drugs

Prior studies have demonstrated a convincing connection between Topamax and serious side effects to unborn children. The research linked the use of Topamax by pregnant women to birth defects, including cleft lips and cleft palates. However, a recently concluded study provides the most comprehensive research spanning a decade.

The research, published in the American Journal of Obstetrics & Gynecology, shows that Topamax use during the first trimester of pregnancy is the most risky for unborn children. The data shows that mothers who use Topamax during their first trimester have a fivefold increase in the chance of their child being born with a cleft palate or lip.

Cleft palates or lips, sometimes referred to as notched lips, can contribute to problems with speech, eating and ear infections. The defects typically necessitate corrective surgery. Further, the conditions create cosmetic concerns.

Unfortunately, the manufacturers of Topamax didn’t sufficiently warn mothers about its risks. The drug’s label now bears an explicit warning about concerns with Topamax and the first trimester of pregnancy, but the warning came too late for many mothers and their children.

If you took Topamax during pregnancy and your child has a birth defect, contact an experienced Michigan birth defects attorney to discuss your options.
