Carbatrol has controlled my seizures for months now. This weekend, though, I had two. The only thing I can think of is that the medicine was accidentally left sitting on the stovetop which caused it to become warm. If this was the cause, my main question is: Does improper storage of Carbatrol cause it to be temporarily less effective and will improve once properly stored? Or, has the whole bottle been permanently rendered ineffective due to the heat? (not scorching hot, just warmed a little)
