Hi,

Thanks for the query.

Topamax makes the implanon less effective, this is true. The quantitative assessment has not been done in studies so it is difficult to comment how much less effective does it make. You should discuss other family planning options with your family planning doctor, may be intrauterine contraceptive devices are better choice for you.

Let me know if I can assist you further.

Best wishes.
