I took Topamax for my Neuralgia, But I feel I didn't get much relief on it. It had too many side-effects that I just couldn't handle in the end. It made me so dizzy and nauseous, and I couldn't keep food down. I was prescribed 75mg per day, but could only handle 50mg per day. I took it for 2 months, but it gave me stomach pains and constant eye pain, so my Neurologist decided I should try something else.
It probably works well for some people, but it has strong side-effects. It might work for someone who doesn't have stomach problems. I do have other stomach problems, so it didn't help me at all.
