By Mayo Clinic staffIt's not necessary to lower your child's fever to stop a febrile seizure. So don't try to give your child fever medications during a seizure. For the same reason, don't place your child in a cooling tub of water. It's much more practical, more comfortable — and safer — for your child to remain lying on the carpet or a bed.
Most febrile seizures stop on their own within a couple of minutes. If your child has a febrile seizure that lasts more than five minutes — or if your child has repeated seizures — call for emergency medical attention.
More serious episodes
In rare cases, the seizure may continue until your child arrives at the emergency room. If this happens, a doctor may order medication that's administered either through your child's rectum or intravenously to stop the seizure.
If the seizure is prolonged or accompanied by a serious infection or if the source of the infection can't be determined, your doctor may want your child to stay in the hospital for further observation. But a hospital stay isn't routinely necessary for simple febrile seizures.
