Keep calm and reassure other people who may be nearby, (clear away as many people as possible).
Don't hold the person down or try to stop their movements.
Do not move the person.
Time the seizure with your watch.
Clear the area around the person of anything hard or sharp.
Loosen ties or anything around the neck that may make breathing difficult.
Put something flat and soft, like a folded jacket, under the head.
What to do if someone has a seizure:
Turn them gently onto one side.
This will help keep the airway clear.
Do not try to force the mouth open with any hard implement or with fingers.
It is not true that a person having a seizure can swallow his tongue.
Efforts to hold the tongue down can cause injury.
Don't attempt artificial respiration except in the unlikely event that a person does not start breathing again after the seizure has stopped.
Stay with the person until the seizure ends naturally.
Be friendly and reassuring as consciousness returns.
Offer to call a taxi, friend or relative to help the person get home if they seems confused or unable to get home by them self.
