Phenytoin for Epilepsy "I had my first grand mal seizure out of the blue at 26 years of age, 39 years ago! Dilantin has kept me free from seizures when I have remembered to take the medication. Over the years, I have had several other seizures, but only due to neglecting to take the tablets. I am on 330 mg per day (130 mg in the morning and 300 mg in the evening). I am very thankful to God for Dilantin! I do have a real tendency to be always tired and swollen gums, but otherwise no other side effects."

Phenytoin for Seizures "I began having focal seizures in 2011, not knowing what was going on. I wasn't diagnosed until 2013 after my first Grand Mal. Began taking Dilantin 500 mg per day. Seizures were much better, but my memory is worse, and I have no libido. I am way more easily agitated. If I miss a dose, I will generally have a focal seizure. Doctor wants to add Keppra, but I am a little scared because of the depression possibility. I have withdrawn from friends a little already and do not need to add to that. Plus, when I took it last week, I was in bed exhausted at 7:30 for no apparent reason."

Phenytoin for Seizures "After about 8 days of being on Dilantin, I had a horrible allergic reaction. I woke up at like 4:30 with unbearably itchy hives that literally covered my whole body... face, shoulders, chest, stomach, back, buttocks, and legs... even on the backs of my hands and feet, with a few spots on the palm of my hand. It sucked, needless to say. It also made me really tired all day, even though I'd take it at night. I'm now starting on Keppra. Hope it works."

For Seizures "After 4 known grand mal seizures, my doctor put me on phenytoin 2 months ago. Do not have too many complaints except my head feels like something is crawling in it sometimes, forgetting things, like common names for things, people's names, and being tired. I am 48 years old, never would take aspirin but want to be safe for myself and others. My last seizure... there was no telltale sign before, and I was just moments from getting into my car."
