topamax will interfere with the effectivness of birth control pills.

Since Topamax is one of my main medications, this was an issue. I have tried depo shots and other methods in the past and had major problems. I have many allergies to all sorts of things, and would have a lot of problems when trying to use condoms, diaphrams, or spermacides.

My gyno suggested the plain copper IUD. It was a bit of a pain for a couple weeks, but has been great ever since. Doesn't interfere with any medications, and you don't have to remember to take anything. Doesn't cause any weight gain etc. Have had no side effects at all. Well, maybe a bit more cramps - but I am close to menopause and was having them anyway. It's good for up to 10 years, so will carry me until I won't need birth control any more. Occasionally get a bit of discharge mid cycle, but nothing I can't put up with compared to the risks of birth control pills. I love it and wish I had used one years ago!
