Menstrual cramps, or dysmenorrhea, are throbbing pains in your lower abdomen. They result from the uterus' strong contractions. Many women have cramps before and during their periods. Menstrual pain symptoms include:  Intense, throbbing pain in your lower abdomen Dull, constant ache in your abdomen Pain that radiates to your lower back and thighs Nausea Loose stools Headache Dizziness Begin taking the pain reliever at the beginning of your period or when you feel menstrual cramp symptoms. Continue taking the medication as indicated on the packaging (or by your doctor) for 2 to 3 days. You also may stop taking medication if your cramps subside. There are many options available for pain relievers:  Over-the-counter pain relievers like ibuprofen (Advil, Motrin IB, etc.) or naproxen sodium (Aleve) can help relieve your cramps.  The menstrual pain reliever Midol contains the pain reliever acetaminophen plus the stimulant caffeine and antihistamine pyrilamine maleate. Midol works to decrease menstrual pains, headaches, and bloating. If your cramps do not subside with pain killers, talk to your doctor about hormonal birth control pills. These pills contain hormones that prevent ovulation and reduce the severity of menstrual cramps. You can also receive hormones in other forms including via injection, an arm implant, a skin patch, a vaginal ring, or an intrauterine device (IUD). All these methods can reduce your cramps. Talk to your doctor about which is right for you. If over-the-counter pain relievers don't work for you, you can talk to your doctor about prescription-strength nonsteroidal anti-inflammatory drugs (NSAIDs). If your menstrual pain is extreme, talk to your doctor about tranexamic acid (Lysteda). This prescription drug is taken to reduce heavy bleeding and severe cramps. You only need to take it during your menstrual cycle.
