What is a good migraine medication that is comparable to Topamax, without the side effects?
I had been taking Topamax for migraines. I was on 400mg a day and it helped really well, but recently found I have a kidney stone due to using Topamax so I am trying to find a different med. I can take for it. For those of you that don’t know, Topamax is used to prevent migraines, not to help with the pain. If anyone has personal experience I would prefer your answer. I don’t want answers like imitrex, maxalt, zomig, as these are to treat the pain after you have gotten a migraine. I want an answer for a med to prevent the migraines. Thanks in advance.
