How to help period pains? My friend is laying on her bed in agony, what can she so that will work fast!?

Well. If she has no contraindications, give her 800 mg of ibuprfin every 6 hours with extra strength tylenol, (acetaminophen) 2 every 6 hours. If she is becomming disabled then the pill may be in order. Good luck.
See below. If she is in agony - this could be an emergency such as an ovarian torsion - get her to an emergency room.
