Kneel by the patient's head place one arm under it, and undo collar and belt. Insert in the mouth something that he cannot swallow, such as a stick, or a pocket-knife wrapped in handkerchief, to prevent the tongue from being bitten. Get him away from anything against which he might strike and injure himself, but do not try to open his hands or restrain his movements. When the attack has passed, do not rouse, but let him sleep, with warmth to the feet.
Do nothing. Appear quite indifferent. A show of sympathy will only make matters worse.
