Dysfunctional Uterine Bleeding


Dysfunctional uterine bleeding (DUB) is abnormal uterine bleeding that is caused by a problem with your hormones. You may have bleeding from your uterus at times other than your normal monthly period. Your monthly periods may last longer or shorter, and bleeding may be heavier or lighter than usual.



  • Hormones help decrease bleeding by making your monthly periods more regular. Sometimes this medicine may be given as birth control pills.
  • NSAIDs help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
  • Iron supplements may be given if your blood iron level decreases because of heavy bleeding. Iron may make you constipated. Ask your healthcare provider for ways to prevent or treat constipation. Iron may also make your bowel movements turn dark or black.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.


  • Apply heat on your lower abdomen for 20 to 30 minutes every 2 hours for as many days as directed. Heat helps decrease pain and muscle spasms.
  • Include foods high in iron if needed. Examples of foods high in iron are leafy green vegetables, beef, pork, liver, eggs, and whole-grain breads and cereals.
  • Keep a diary of your menstrual cycles. Keep track of the number of tampons or pads you use each day.
  • Talk to your healthcare provider before you start a weight loss program. You may need to wait until the abnormal bleeding has stopped before you try to lose weight. The amount of iron in your blood should be normal before you lose weight.

Contact your healthcare provider if:

  • You need to change your sanitary pad or tampon more than once an hour.
  • Your medicine causes nausea, vomiting, or diarrhea.
  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • You continue to bleed heavily, or you feel faint.
