“Febrile seizures are seizures triggered by a fever of at least 100.4° F (about 38° C).
Most febrile seizures are harmless and caused by fever from a minor infection.
Less often, a febrile seizure is the first sign of a previously unrecognized neurologic disorder.
Doctors sometimes do blood tests and a spinal tap to check for serious disorders that can cause seizures.
Children generally need drugs to end the seizure only if it lasts 5 minutes or more to minimize the risk of a long-lasting seizure or status epilepticus.
Most children do not need to take drugs to prevent febrile seizures.”
