Topomax, neurontin, depakote, cafergot, imitrex (bad reaction, had an attack of angina, thought it was a real heart attack) you name it, I've tried it. I have Barometric Pressure migraines, and they are absolutely the hardest to treat, they don't even really know why storms, rain, very high humidity, will cause my brain to swell beyond the confines of my skull, only treatment for that is a cup of very strong cup of hot coffee, instant relief, blood vessels constrict immediately. This is then followed by the worst pain I have ever experienced, worse than post-operative pain, nothing comes near this migraine pain except demerol, 200mgs, and for at least 4-5 hours, I have true relief from pain, but not from the accompying symptoms, vertigo, ear ache, nausea, acid reflux, vision problems, inability to sleep, to name a few.
I too was on Topamax for migraines, and when the generics became avaliable they switched me to them. For all of my migraine meds. Maxalt, Imatrex, and Topamax. I got violently ill each time I took an Imarex so I stopped getting those completely. I fought to get the Maxalt switched back to the named brand and after three months of not being able to move off the couch, eat, take showers, and wanting to basically kill myself. I finally figured out that it was the generic Topamax making me sick and I had to fight with my insurance company for preauthorizaton for a year of brand name Topamax to be covered!! But it is so worth it, I will never put another generic migraine medication into my body again!! I can however take other generic meds. I don't know why, just what happens to my body when I do. I also know that the Topamx helps to keep my daily Migraines away and if it wasn't for the brand name Topamax I wouldn't be alive today, after dealing with daily headaches for over 30 years. Don't let anyone tell you not to listen to what your body tells you!!
