Topiramate
migraine prevention
"Prescribed a half 50 mg tab at bedtime for a week.  It's been two days and I have no more headaches! Finally!  I have a strange side effect of pain in my private area though.  Does anyone else have this issue?  It's just annoying.  I hope it doesn't get any worse.  I've been looking for a migraine med that actually helps without too many side effects."
