Comments

Zonegran were bad news. They put me in a 'mental fog' and it took me forever to realize what was causing it. The rash went away after a week, however the tiredness I was feeling as a result of them turned into confusion and seemed to take my thought process away. (Hard to explain.) I stopped taking the Zonegran and I now am feeling more clear headed and have had less flare ups. I'm done experimenting with pills! I always seem to have bad side effects and they don't do anything for the pain, so forget it. My main goal now is more aggressive physical therapy along with HBOT*. But, I wanted to let you know about the Zonegran. (And I was only taking one pill at night, thankfully didn't step up to taking two of them.) Cheryl - Las Vegas, Nevada, USA
*HBOT
stands for Hyperbaric Oxygen Therapy. You will find details on the HBOT page in "Treatments on RSD Alert"

I took Zonegran, and the first three times there was a definite increase in RSD pain after the dose accompanied by a very thick mental fog (considering the dose of 1/2 of 100 mg. capsule). It was not like my daily memory trouble, but the kind of mental fog one gets from a general anesthetic or narcotics they are unaccustomed to taking. I have decided not to "fool around" with a drug that was increasing my pain and, with my doctor's permission, stopped it. I am sure now what I think about the drug: No good for RSD. However, each patient is individual, and it may be of use to someone. Amanda - Pennsylvania, USA

My doctor ramped me up to 300 mg of Zonegran a night. It did not help the pain, did help headaches, but worst of all caused petite mal seizures. The doctor abandoned my care immediately when the seizures started. I weaned myself off the drug and am seeking a new doctor. Maybe zonegran has helped some people, and I wish them the best, but I was in a fog, forgetful, in constant pain... pretty much more a mess than before the drug. Donna - Arlington, Texas

Remember - RSD/CRPS is rooted in the nervous system. The discovery that epilepsy drugs may have beneficial effects for RSD patients does not imply that they have epilepsy.
