Seizure first aid – what to do and what not to do

How to help someone having a convulsive seizure, why you must never put anything in their mouth, and exactly when a seizure becomes an emergency.

What to do

  1. Note the time. How long it lasts decides whether this is an emergency, and afterwards nobody can remember.
  2. Move furniture and hard objects out of the way. Do not move the person unless they are in danger, such as in water, on a road or near a fire.
  3. Put something soft under their head.
  4. Loosen anything tight around the neck.
  5. Stay with them and let the seizure run its course.
  6. Once the jerking stops, roll them onto their side so the airway stays clear and any vomit can drain.
  7. Stay until they are fully awake and oriented, and tell them calmly what happened — people are often confused and frightened afterwards.

What not to do

  • Do not hold them down or try to stop the movements. You will not shorten the seizure and you may cause injury.
  • Do not give water, food or tablets until they are fully awake and swallowing normally.
  • Do not throw water on them or slap them.
  • Do not crowd around. Give space, and ask onlookers to move back — dignity matters here and so does air.

When to call an ambulance

For a person with known epilepsy having their usual kind of seizure, which stops within a few minutes and is followed by a normal recovery, an ambulance is not automatically needed. It is still worth telling their clinic, because a change in pattern or frequency is information their treatment depends on.

Seizures that do not involve convulsions

Not every seizure involves falling and shaking. Someone may stare blankly, not respond, wander, pluck at their clothing or repeat a movement, then have no memory of it. Guide them gently away from danger such as traffic or stairs, do not grab or restrain them, stay with them, and wait for them to come round on their own.

Common questions

Should I put something in the mouth of someone having a seizure?
Never. People cannot swallow their tongue, and forcing anything in breaks teeth, causes choking and gets rescuers bitten. Clear the space around them and roll them onto their side once the jerking stops.
How long should a seizure last before I call an ambulance?
Five minutes. Also call if another seizure starts before they recover, if they do not regain consciousness, if it is a first-ever seizure, if it happened in water, or if they are injured, pregnant or have diabetes.
What do I do after a seizure stops?
Roll them onto their side so the airway stays clear, stay with them until they are fully awake and oriented, and tell them calmly what happened. Do not give food, drink or tablets until they are swallowing normally.
