Deep sleep after a seizure: what to know

After a seizure, someone may be confused, exhausted, have a headache or sleep deeply. Recovery time varies. Stay nearby, place the person on their side if they are breathing, loosen tight clothing and check that the airway remains clear. Do not restrain them, put anything in their mouth or give food, drink or medicine until they are fully alert. Note when the seizure started and ended and what recovery looked like.

Remain calm and reduce noise and bright light. Check breathing and responsiveness regularly without shaking the person. Once awake, reassure them and help them rest. Arrange medical review after a first seizure, an unexplained seizure, an injury, or a change from their usual pattern. Possible triggers can include low blood sugar, alcohol withdrawal or infection, so tell the clinician about illness, medicines, alcohol and missed meals.

Call emergency services if the seizure lasts longer than usual, repeats without recovery, causes serious injury, happens in water, or breathing remains abnormal. Get urgent help if the person cannot be woken, has a severe headache, stiff neck, fever, new weakness or ongoing confusion. A first seizure always needs prompt assessment.

Ask what recovery pattern is expected, how to use any prescribed rescue medicine, whether driving or bathing needs temporary precautions, and which symptoms should prompt emergency help. Ask whether testing for hypoglycaemia, meningitis or alcohol-related causes is relevant.
