Next Steps

Causes

Cause

  • The medical name for painful cramping during a girl's period is dysmenorrhea.
  • Normal cramps happen in over 60% of girls.
  • This cramping is caused by strong muscle squeezing of the uterus. This is triggered by a high prostaglandin (a hormone) level.
  • An egg release from the ovary (ovulation) is needed to cause cramping. Therefore, the onset is most often 12 months or more after the first period.
  • Medical causes of severe menstrual cramps include pelvic inflammatory disease (PID) and endometriosis. An ovarian cyst can also cause very bad cramping.

Age of Onset of Menstrual Cramps

  • Peak age of onset: 1 to 2 years after periods first start
  • During the first year after periods start, only 7% or less of teens will have cramping. Some of these girls will have a medical cause such as a blockage.

Pain Scale

  • Mild: Your child feels pain and tells you about it. But, the pain does not keep your child from any normal activities. School, play and sleep are not changed.
  • Moderate: The pain keeps your child from doing some normal activities. It may wake him or her up from sleep.
  • Severe: The pain is very bad. It keeps your child from doing all normal activities.

Care Advice for Menstrual Cramps

 

  1. What You Should Know About Menstrual Cramps:
    • Cramps happen in over 60% of girls.
    • Pain medicines can keep cramps to a mild level.
    • Cramps can last 2 or 3 days.
    • Here is some care advice that should help.
  2. Ibuprofen for Pain:
    • Give 2 ibuprofen 200 mg tablets 3 times per day for 3 days.
    • The first dose should be 3 tablets (600 mg) if the teen weighs over 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.
  3. Naproxen if Ibuprofen Doesn't Help:
    • If your teen has tried ibuprofen with no pain relief, switch to naproxen. No prescription is needed.
    • Give 220 mg (1 tablet) every 8 hours for 2 or 3 days.
    • The first dose should be 2 tablets (440 mg) if the teen weighs over 100 pounds (45 kg).

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