Is this your symptom?

  • Cramps in the lower belly or pelvis. They start during the first 1 or 2 days of your period.
  • Cramps only happen during menstrual bleeding
  • Report of similar cramps in the past are helpful

Cause

  • The medical name for painful cramping during a period is dysmenorrhea.
  • Normal cramps happen in over 60% of women.
  • This cramping is caused by strong muscle squeezing of the uterus. This is triggered by a high prostaglandin (a hormone) level.
  • Medical causes of severe menstrual cramps include pelvic inflammatory disease (PID) and endometriosis. An ovarian cyst can also cause very bad cramping.

Pain Scale

  • Mild: the pain does not keep you from any normal activities. Work, activities and sleep are not changed.
  • Moderate: the pain keeps you from doing some normal activities. It may wake you up from sleep.
  • Severe: the pain is very bad. It keeps you from doing all normal activities.

Care Advice for Menstrual Cramps

What You Should Know About Menstrual Cramps:

  • Cramps happen in over 60% of women.
  • Pain medicines can keep cramps to a mild level.
  • Cramps can last 2 or 3 days.
  • Here is some care advice that should help.

Ibuprofen for Pain:

  • Take 2 ibuprofen 200 mg tablets 3 times per day for 3 days.
  • The first dose should be 3 tablets (600 mg) if you weigh more than 100 pounds (45 kg).
  • Take with food.
  • Ibuprofen is a very good drug for cramps. Advil and Motrin are some of the brand names. No prescription is needed.
  • The drug should be started as soon as there is any menstrual flow. If you can, start it the day before. Don't wait for cramps to start.
  • Note: acetaminophen products (such as Tylenol) are not helpful for menstrual cramps.

Naproxen if Ibuprofen Doesn't Help:

  • If you have tried ibuprofen with no pain relief, switch to naproxen. No prescription is needed.
  • Take 220 mg (1 tablet) every 8 hours for 2 or 3 days.
  • The first dose should be 2 tablets (440 mg) if you weigh more than 100 pounds (45 kg).
  • Take with food.

Use Heat for Pain:

  • Use a heating pad or warm washcloth on your lower belly. Do this for 20 minutes 2 times per day. This may help to reduce pain.
  • A warm bath may also help.

What to Expect:

  • Cramps last 2 or 3 days.
  • They will often happen with each period.
  • The cramps sometimes go away for good after the first pregnancy and delivery.

Call Your Doctor If:

  • Neither ibuprofen or naproxen helps the pain
  • Cramps cause you to miss work, school or other events
  • Pain lasts over 3 days
