I was switched over to topiramate some time ago when, on my insurance, the Topamax I had been taking for years jumped to $1500 a month. I have occasional seizures on it, but I don't have a choice. I went to pick my refill up last week, and now they've switched manufacturers on me. I didn't really think much about it until I noticed yesterday that pop tastes funny again. That's a side effect I had with the brand name stuff. I'm wondering if it's possible that a mere switch of manufacturer could also put me at risk for more seizures?
