I started Topamax over a year ago and titrated up slowly, 25 mg a week until I got to 125 mg a day, split dosing. I was started for migraine prophylaxis. Once it kicked in, it did an amazing job of keeping my headaches away. But, here is something really important: if you are going to have surgery, there are contraindications with Topamax and anesthesia. No one either knew this or told me this and I only found out weeks after I went through a really lousy experience. What I believe happened is that the combination threw my body's pH balance off. I felt like my insides were burning and it was only at that point that I started to experience the severe diarrhea and weight loss, fatigue, and general malaise. It lasted for weeks. All I could figure at the time was that it was just taking me a really long time to recover from my surgery (ovarian cyst removal and unilateral oophorectomy), but that didn't make sense. I felt like I had a horrible flu for weeks. I kept seeing my doctor saying something was wrong with the way I was healing (ie, i had an infection or something). Anyway, this eventually stabilized as I back off the Topamax. I was so weak that I didn't even realize the memory issues or word finding problems, but when I started to feel better physically, I did notice those. That REALLY bugged me. I like to be sharp. So, I tapered off. About 1.5 months later, my headaches started coming back. I decided to try Topamax again feeling that now I understood it much better and could watch it more closely. Maybe this time I could ride out the side effects. Well, this time several months passed at the same dose. My headaches were still there and I had no side effects. We upped the dosage. Still having headaches, but no diarrhea, no weight loss (in fact, weight gain of 15 pounds over the last 9 months since last Topamax round), no real problem with word finding, etc. Up to about 200 mg daily by this time. It has been about 6 months and I have started tapering down and about to give up, down to 150 mg daily right now. NOW, here is something interesting: I just have another surgery, but no anesthesia. It was oral surgery. I did, however, have to take a round of antibiotics. It seems that this round of antibiotics has kicked the cycle into gear because I started having gastric problems, perhaps because of the antibiotics (although in the past, I have not had problems with antibiotics before, ALTHOUGH I did have to take them last year with my in-hospital surgery), I don't know, but I have finished the round of antibiotics and I am still having diarrhea. My appetite is suppressed, and I have lost 5 pounds in this last week. Many people say you cannot lose weight if you stop Topamax and restart it later. That is an interesting. I wonder why that is. Topamax is such a strange drug. Why did it not work for me the second time I took it, or at least for 9 months? Is it just now kicking in with its side effects as the result of upsetting my gastric system? Will it start working now for my headaches, too? I think I will continue to taper off or maybe see if I can prevent headaches on a very low dose. Oh, another interesting thing: I found the first time I took Topamax, it made me feel energized. I found that this time, it made me feel the opposite. I sleep a lot more and feel more sleepy during the day.
