A member asked:
Does 100 mg of topomax a day interfere with the birth control ortho novum 7/7/7?
A doctor has provided 1 answer
Can: Topomax (topiramate) may decrease the serum concentration of contraceptives (estrogens) and contraceptive failure is possible, particularly at higher topiramate doses (i.e., 200mg/day or greater). At 100 mg of topmax, recommend at least 50 mcg of ethinyl estradiol. A non-hormonal form of contraception should be considered if a greater certainty of pregnancy prevention is desired.
