First aid for tonic-clonic seizures

Once a tonic-clonic seizure has started there is nothing you can do to stop it.

• If there are sharp or dangerous objects near the person, move those objects if possible. You should only move the person if they are near water or some other dangerous situation.

• Try to cushion the person’s head. You could do this with a rolled up jumper or coat or even with your hands.

• It is likely that the jaw will be clenched during this type of seizure. Do not try to open their mouth or to put any objects in their mouth as this could damage their teeth or gums or block their airway.

• When the seizure is over, turn the person on to their left side, into the recovery position. At this stage make sure their airway is clear and let the person recover. This procedure is taught on first aid courses, and so will be familiar to trained first aiders at work. You might also consider if it’s appropriate for other members of staff to be shown how to put someone in the recovery position.

• Stay with the person if possible, until you are satisfied the seizure is over and that they do not need any further assistance.

• Some people need to rest for some time after a seizure and your general first aid policy for supervising staff who are unwell could then be applied.
