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. RSD has spread to my left arm into my back and now my legs are beginning to show signs. The doctor who put me on the zonegran never told me how to get off the drug; the neurologist said not to take me off it without supervision because of the dangers of further seizures. Originally I was put on the Zonegran for headaches...not seizures.
Finally, I took myself off the drug. Withdrawal was very difficult and led to strange thoughts, total sadness and hopelessness. I am not allowed to
drive because of the seizures while on the Zonegran. Donna - Arlington, Texas

I took myself off Zonegran. Warn anyone planning on geting off Zonegran that they hould have a doctor's help. The withdrawal had potentially dangerous side effects. Somewhere in the literature I read that there may be "abnormal thoughts" but there was an incredibly sadness that overtook me and I actually slit my wrists. This is not my type of behaviour at all... I cringe at nicking my legs if I shave them, so it was quite out of character. The sadness and hoplessness were overwhelming, beyond depression. It passed after a couple of days, but was very dangerous to do on my own. Now I am more myself and feel quite well and am so glad to be free of
Zonegran. Please advise anyone not withdraw without a physicians help. Name supplied.

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.
