I take Topamax for fibromyalgia -- 200 mg/day: 100 mg/a.m., 100 mg/p.m., and have been on it for about five months now. It has helped some with the pain, but I still need painkillers and muscle relaxers daily. I think you're having worse pain now because (if it works like Imitrex) the blood vessels may still be restricted or expanded. I forgot what exactly it does with the vessels. Phentermine and Topamax are two very different types of medications. Phentermine is intended to be used as a weight loss aid, while Topamax is intended to be used to treat certain seizure disorders or prevent migraines from occurring. Both medications, however, may cause weight loss. Dear breakingfree2013: It is possible that bupropion (Wellbutrin) may cause your symptoms of tremors and joint pain. Please contact your provider and pharmacist to report the adverse effects and have them confirm by conducting a complete medication review, including prescription, over-the-counter, and any dietary and herbal supplements.

Topamax is the brand name of topiramate, an anticonvulsant drug used to prevent seizures and reduce the frequency of migraines. While its exact mechanism of action is unknown, studies suggest. I was on Paxil for anxiety for about 2 years and gained almost 40 pounds. The Paxil was initially very helpful, however, the weight gain was not something that I was willing to deal with and the drugs effectiveness waned.
