Management of Breakthrough Bleeding with IUD
For breakthrough bleeding with an IUD, first rule out pregnancy, infection, and IUD displacement, then treat with NSAIDs for 5-7 days during bleeding episodes as first-line therapy. 1, 2
Initial Assessment
Before initiating any treatment, evaluate for underlying pathology that could explain the bleeding:
- Check for IUD displacement by verifying string presence on pelvic examination 1, 2
- Rule out pregnancy with urine or serum hCG testing 3
- Screen for sexually transmitted infections (STDs), particularly if the patient has been using the IUD for several months and develops new-onset bleeding 1
- Consider new pathologic uterine conditions such as polyps or fibroids, especially in established IUD users with new bleeding patterns 1
If any underlying gynecological problem is identified, treat the condition or refer for specialized care rather than treating the bleeding symptomatically. 1
Counseling and Expectant Management
Reassure patients that breakthrough bleeding is common and generally not harmful, particularly during the first 3-6 months of IUD use. 1, 2
Copper IUD (Cu-IUD):
- Unscheduled spotting, light bleeding, heavy bleeding, or prolonged bleeding is expected during the first 3-6 months 1
- Bleeding typically decreases with continued use 1
Levonorgestrel IUD (LNG-IUD):
- Irregular bleeding is common in the first 3-6 months 2
- Approximately 50% of users experience amenorrhea or oligomenorrhea by 2 years of use 2
Medical Treatment Algorithm
First-Line Treatment: NSAIDs
If bleeding persists beyond the initial adjustment period and the patient requests treatment, prescribe NSAIDs for 5-7 days during bleeding episodes. 1, 2, 4
- NSAIDs reduce menstrual blood loss by 20-60% in Cu-IUD users 5, 4
- Multiple NSAIDs have demonstrated efficacy including mefenamic acid, indomethacin, flufenamic acid, and diclofenac 1, 4
- Avoid aspirin, as it may increase bleeding in some patients 1
Second-Line Treatment for LNG-IUD Users
If NSAIDs are ineffective in LNG-IUD users, add hormonal treatment with combined oral contraceptives (COCs) or estrogen for 10-20 days. 2, 3
This approach is specific to LNG-IUD users and provides additional hormonal support during the adjustment period. 2, 3
Alternative Agents (Limited Evidence)
Tranexamic acid can be considered for Cu-IUD users with heavy bleeding, though safety data are limited. 1, 5, 4
- One study showed significant reduction in menstrual blood loss with tranexamic acid 1
- Critical caveat: Tranexamic acid is contraindicated in women with active thromboembolic disease or history of thrombosis 1
- Use for 5 days during menstruation if prescribed 5
When to Consider IUD Removal
If bleeding persists despite treatment and the patient finds it unacceptable, counsel about alternative contraceptive methods and offer method change. 1, 2
The decision to remove the IUD should be made when:
- Medical treatment fails to adequately control bleeding 1, 2
- The patient's quality of life is significantly impacted 1
- Underlying pathology is identified that warrants removal 2
Common Pitfalls to Avoid
- Do not dismiss bleeding without ruling out pregnancy, infection, or structural pathology 3
- Do not routinely schedule follow-up visits—instead, advise patients to return if they have concerns or if bleeding becomes unacceptable 1
- Do not assume all bleeding is benign—new-onset heavy bleeding in established IUD users warrants investigation for pathology 1
