Treatment for prolonged seizures usually involves giving an anti-seizure medication and monitoring the child’s heart rate, blood pressure, and breathing. If the seizure stops on its own, anti-seizure medication is not required. After a simple febrile seizure, most children do not need to stay in the hospital unless the seizure was caused by a serious infection requiring treatment in the hospital.

After the seizure has stopped, treatment for the fever is started, usually by giving oral or rectal acetaminophen or ibuprofen and sometimes by sponging with room temperature (not cold) water.
