I am new to this drug. I'm taking 200 mg and wondering how the side effects are for others on it. I'm on it now for almost a week and feel Eh. ## Have you experienced any other side effects, so far? The FDA lists the typical ones for this medication as possibly including nausea, drowsiness, dizziness, memory problems, menstrual pain and nervousness. It contains the active ingredient Topiramate and is classified as an antiseizure medication. Can anyone that's taken it chime in, please?
