migraine prevention
"I was on topamax for a month and lost 6lbs. I could handle the tingling in my hands and feet but I stopped taking it because my period never stopped!  It started the day after my first dose and ended three days after I stopped taking topamax. I do have the birth control Implanon implanted in my arm. So maybe those drugs combined doesn't work well. I still had migraines but they weren't intense."
