Interaction between Birth Control Pills and Topamax

Pregnancy and Topamax. The active ingredient in Topamax is called topiramate. Women should be aware of the fact that topiramate may alter the effectiveness of birth control pills. Women should also consider the risks of combining the use of Topamax and pregnancy. This side effect of Topamax should be made known to women of child-bearing age. The other side effects of Topamax such as oral cleft birth defects should be considered as well if a woman is taking this prescription medication while pregnant. Studies have suggested that women who use Topamax and birth control pills at the same time are at a higher rate of contraceptive failure. An increase in the metabolism of estrogen and progesterone has been indicated by these studies. This side effect of Topamax leads to the failure of the hormone-based birth control pills. The U.S. Food and Drug Administration (FDA) also considered the risks of using Topamax. Earlier this year, Topamax was moved from Pregnancy Category C to Pregnancy Category D. The Topamax warning changed after data from studies indicated a higher risk of babies being born with oral clefts when women took the drug during the early months of pregnancy. For this drug to be in the Pregnancy Category D, it means there is evidence from studies using human data that suggests a fetus is at risk for Topamax birth defects when women take the drug during pregnancy. It is important to consider the risks of having a child with a Topamax birth defect versus the benefits before committing to take this medication.
The North American Antiepileptic Drug (AED) Pregnancy Registry provided data that indicated infants who are exposed to Topamax during the first three months of pregnancy were born with a Topamax cleft lipat a significantly higher number when compared to the rate of birth defects experienced as a result of other antiepileptic drugs. If you or someone you know has given birth to a child with a side effect of Topamax, you should contact a Topamax lawyer as soon as possible for a consultation so they can advise you on filing a Topamax lawsuit.
