What anti-seizure drugs can affect birth control pills?

ANSWER

Some anti-seizure drugs can make birth control pills less effective. These drugs include:

Be sure to use another form of birth control (like an IUD, a diaphragm, or a condom) if you take anti-seizure medication.

Birth control medication won't interfere with how well your anti-seizure drugs work.

  • Carbamazepine (Carbatrol, Epitol, Equetro, Tegretol)
  • Felbamate (Felbatol)
  • Oxcarbazepine (Trileptal)
  • Phenobarbital (Luminal)
