How to treat heavy menstrual bleeding caused by an Intrauterine Device (IUD)?

Management of Heavy Menstrual Bleeding Associated with IUD Use

For heavy menstrual bleeding caused by an IUD, first rule out underlying gynecological problems, then use NSAIDs as first-line treatment for 5-7 days during bleeding episodes. 1

Initial Assessment

When a patient presents with heavy menstrual bleeding with an IUD:

1. Rule out underlying conditions first:

   • Check for IUD displacement
   • Screen for STDs
   • Exclude pregnancy
   • Evaluate for pathologic uterine conditions (polyps, fibroids)
   • Consider coagulation disorders 1, 2

2. If an underlying gynecological problem is found:

   • Treat the specific condition or refer for appropriate care 1

Treatment Algorithm for Heavy Bleeding with IUD

First-Line Treatment:

• NSAIDs for 5-7 days during bleeding days 1, 3
  • Reduces menstrual blood loss by 26-60% 2
  • Options include:
    • Naproxen
    • Mefenamic acid
    • Ibuprofen

Second-Line Treatment:

• Tranexamic acid for 4-5 days starting from first day of menstrual cycle 2, 3
  • Reduces menstrual blood loss by approximately 50%
  • CAUTION: Contraindicated in women with active thromboembolic disease or history/risk of thrombosis 1, 2

For Copper IUD Users:

• NSAIDs are particularly effective for copper IUD users with heavy bleeding 2, 4
• Consider vitamin B1 which has shown to reduce the number of pads used per day and fewer bleeding days (low-certainty evidence) 3

For LNG-IUD Users:

• Heavy bleeding is uncommon with LNG-IUD use 1
• If it occurs, NSAIDs can still be used as first-line treatment

When to Consider IUD Removal

If bleeding persists despite treatment and the woman finds it unacceptable:

1. Counsel on alternative contraceptive methods
2. Offer another method if desired 1

Important Clinical Considerations

• Heavy bleeding with LNG-IUD is uncommon and should raise suspicion for underlying pathology 1
• Unscheduled spotting or light bleeding is expected during the first 3-6 months of IUD use and generally decreases with continued use 1
• Approximately 50% of LNG-IUD users experience amenorrhea or oligomenorrhea by 2 years of use 1
• Enhanced counseling about expected bleeding patterns can improve method continuation 1

Pitfalls to Avoid

• Don't assume bleeding is solely due to the IUD without ruling out other causes, especially with new onset of heavy bleeding after months of use 1, 2
• Don't use high-dose aspirin for treatment as it may increase blood loss in women with baseline menorrhagia 4
• Don't overlook cardiovascular risk factors when considering alternative hormonal methods 2
• Don't delay evaluation of persistent heavy bleeding, as it could mask underlying pathology 2

Remember that while bleeding irregularities are common with IUD use, they are generally not harmful and often improve with time. Proper management can significantly improve quality of life and prevent unnecessary IUD discontinuation 1, 3.
