What should you know about febrile seizure duration?

During a febrile seizure, a child may stiffen, jerk, stare or become unresponsive while fever is present. The event can feel much longer than it is, so start a timer as soon as the movements begin. Note whether the child responds, whether one side is affected and how quickly normal awareness returns.

A short event that ends on its own still needs medical advice when it is the first seizure. A longer event, repeated seizures or incomplete recovery can signal a more serious problem and may require emergency treatment. Fever does not rule out conditions such as meningitis or low blood sugar.

Place the child on their side on a clear, safe surface and protect the head. Loosen tight clothing, keep the airway unobstructed and watch breathing. Do not restrain the child, place anything in the mouth, or give fluids or medicine during the event. Keep timing the seizure until all stiffening and jerking stop, then observe recovery.

Call emergency services when the seizure lasts five minutes or longer, starts again before the child recovers, affects breathing or causes an injury. Seek urgent care for persistent unresponsiveness, a stiff neck, unusual rash, severe illness or a first seizure. If a clinician has provided a rescue medicine plan, follow that plan exactly while awaiting help.

Ask how to use the timer, when a prescribed rescue medicine should be given, which fever symptoms need review and what recovery interval is expected. Ask whether the child needs follow-up after this event and how to document another episode.
