A good way to get rid of menstrual cramps is to take two Tylonol or Motrin tablets. A good way to prevent cramps and menstrual symptoms is to eat bananas or foods high in potassium, calcium, vitamin D, and iron.

If you dont like the medication route you can do some crunches that helps, or use a heating pad. If you do use medication take 800 mg of ibuprofin the 72 hours leading up to your cycle to help with prevention.
