For Seizures "I had my dosage increased 100 mg last year to 400 mg/day and noticed an increase in side effects. My short-term memory is awful, especially with names. I've also noticed mood swings, weight gain, and sensitivity have increased, and I'm still having seizures. It appears it's not the drug for me."

For Epilepsy "I have been on Dilantin and phenobarbital, both taken at night. I haven't had any grand mal seizures in two years. I've noticed some type of rash on my side that doesn't seem to ever go away, and I feel a lot more stress and some weight gain, but with the two mixed together, it works great. I sleep well and have a lot of energy."

For Seizures "I have been on Dilantin since I was about 17. It has been working a lot better than the Depakene I was taking before. When I was pregnant and started to gain a lot of weight, my doctor had to increase the dose. I am 31 now and my seizures are very well controlled while on Dilantin."
