seizures
"I became ill in 1982 at age 33 with encephalitis, brain damage on temporal lobe, and grand mal seizures.  The next year I was also diagnosed with Lupus in addition to epilepsy.  It took 5 years and NIH treatment of 250 mg of Mysoline/ 3 times a day to control my seizures.
It has been controlling my seizures and I am now 65.
AARP denied my brand name Mysoline for seizures even though I was going to pay high co-pays. We pay our own insurance so this is a real problem.  The worst is fighting AARP to pay their part when I know Mysoline works for 27 years.  How  can a person at a desk just suggest other medicines to take when your doctor and you state that this is the best one for you.  "
