Fever-related seizure: what should you know?

During a seizure, the body may stiffen, jerk, stare, or become unresponsive. Fever can accompany a seizure, especially in children, but the fever does not explain every seizure. Other causes can include low blood sugar, withdrawal from alcohol, medication effects, or a serious infection such as meningitis. The appearance, length, recovery, age, medical history, and associated symptoms all matter.

A first seizure needs medical assessment even if movement stops quickly. Do not assume that a normal-looking recovery rules out a cause that needs treatment.

Move hard or sharp objects away and cushion the head. Do not restrain the movements, place food or fingers in the mouth, or give drinks or medicine until the person is fully alert. Turn them onto their side when possible, loosen tight clothing around the neck, and note when the seizure starts and stops. Stay nearby and check breathing after the movements end.

Call emergency services if the seizure lasts longer than expected, repeats without full recovery, causes breathing difficulty, follows an injury, happens in water, or is a first seizure. Urgent assessment is also needed for a stiff neck, severe headache, unusual rash, persistent confusion, weakness on one side, or difficulty waking. Keep the person safe while help is coming.

Ask what may have triggered the event, whether tests are needed, how to manage future fevers, and which emergency number and rescue plan your household should use.
