Seizures
"I am a 47 year old male with seizure disorder/Epilepsy. I had my first Grand Mal seizure at 28. Since then I have been taking Dilantin 100mg 3 times a day. At first (the first 3 months I experienced unbearable side effects lightheadedness, etc.) so my doctor changed me to Keppra. The cost of Keppra was way to expensive so I went back on Dilantin. After several more months my body got used to it and I started having zero side effects . After taking it now for 19 years I NEVER have seizures whatsoever but I never miss a dose. 100 mg 3 times a day. I think it is a wonderful medicine and is very inexpensive."
