Ibuprofen and naproxen sodium are common over-the-counter medications that can help relieve menstrual cramps. A heating pad or hot water bottle may also make you feel better. Other measures to reduce or prevent cramps include:

• Walk or exercise regularly, including pelvic rocking exercises.
• Follow a diet rich in complex carbohydrates, like whole grains, fruits, and vegetables -- but low in salt, sugar, alcohol, and caffeine.
• Practice relaxation techniques like meditation or yoga.
