Our 14 year old daughter was taking cephalexin for a urinary infection. She had been on the medication for a little over 24 hours. While at a friend\'s house playing video games, she had a seizure. She has never had a seizure before. We would like to find out if there are other seizure incidents related to this drug as the emergency room physician felt the drug had no bearing on the seizure. She had a cat scan and her blood was checked at the ER. Neither showed any problems. Her seizure dropped out of nowhere!
