Vigabatrin is a drug that helps with hard-to-control epilepsy and baby spasms. It works by blocking something called GABA transaminase, which makes more GABA in your brain. You can get it as 500 mg pills or in a powdered form.
The usual amount to take is between 1 and 3 grams a day, split up throughout the day. There are 100 tablets in each bottle.
