migraine prevention
"I was given this medication several years ago in an attempt to reduce migraines. I began using the lowest prescribed dose, as instructed by my physician. On the 3rd night, 3-4 hours after taking my 3rd dose, I woke out of a sound sleep with tachycardia (fast heart rate). I didn't know what was up. To "calm down" I took a shower. By afternoon of that day, I knew that it was the medication. I had pressure in my head, tachycardia, nausea. This is about the worst I have ever felt. Needless to say, I had to discontinue Topamax immediately. I long for the day when medications can be chosen based on genetic coding information. For many people, Topamax is a God-send; but not for me."
