What is the management approach for a woman with an implanted contraceptive device (intrauterine device (IUD)) experiencing menstrual irregularities, such as irregular bleeding, heavy bleeding, or amenorrhea?

Management of Menstrual Irregularities with Implanted Contraceptive Devices

For Copper IUD (Cu-IUD) Users

If a woman with a copper IUD experiences bleeding irregularities, reassure her that spotting and heavy bleeding during the first 3-6 months are generally not harmful, then systematically rule out underlying gynecological problems before offering short-term NSAIDs (5-7 days) during bleeding days. 1

Initial Counseling and Reassurance

• Unscheduled spotting, light bleeding, heavy or prolonged bleeding are common during the first 3-6 months of Cu-IUD use and generally decrease with continued use 1
• These bleeding irregularities are not harmful and do not indicate a medical problem 1

Systematic Evaluation for Underlying Problems

When bleeding occurs, especially if it develops after the first few months of use or represents a new pattern, evaluate for: 1

• Cu-IUD displacement - check string position 1
• Pregnancy - always rule out 1
• Sexually transmitted diseases (STDs) 1
• New pathologic uterine conditions - polyps or fibroids 1

Treatment Options if No Underlying Problem Found

If the woman requests treatment and no gynecological problem is identified: 1

• NSAIDs for 5-7 days during bleeding episodes - multiple studies show statistically significant reductions in menstrual blood loss with indomethacin, mefenamic acid, flufenamic acid, and diclofenac sodium 1
• Aspirin is NOT recommended as it showed no benefit or increased bleeding in some women 1

When to Consider Method Change

• If bleeding persists despite treatment and the woman finds it unacceptable, counsel on alternative contraceptive methods and offer another method 1

For Levonorgestrel IUD (LNG-IUD) Users

Women with LNG-IUDs should be counseled that unscheduled spotting is expected during the first 3-6 months, bleeding typically decreases over time with many experiencing amenorrhea by 2 years, and heavy bleeding is uncommon—if it occurs, rule out underlying pathology. 1

Expected Bleeding Patterns

• Unscheduled spotting or light bleeding is expected during the first 3-6 months 1
• Bleeding generally decreases with continued use 1
• Approximately 50% of users experience amenorrhea or oligomenorrhea by 2 years 1
• Heavy or prolonged bleeding is uncommon with LNG-IUD use 1

Management of Irregular Bleeding (Spotting, Light Bleeding, or Heavy Bleeding)

Evaluate for underlying problems: 1

• LNG-IUD displacement
• STDs
• Pregnancy
• New pathologic uterine conditions (polyps or fibroids)

If an underlying problem is found, treat or refer for care 1

Management of Amenorrhea

• Amenorrhea requires no medical treatment—only reassurance 1
• If regular bleeding pattern changes abruptly to amenorrhea, rule out pregnancy if clinically indicated 1
• If amenorrhea persists and is unacceptable to the woman, counsel on alternative methods 1

Treatment Limitations

• No direct evidence exists for therapeutic treatments of bleeding irregularities during LNG-IUD use 1
• If bleeding persists and is unacceptable, counsel on alternative contraceptive methods 1

For Contraceptive Implant (Implanon/Nexplanon) Users

For women experiencing spotting after one year of implant use, provide reassurance that it is generally not harmful, systematically rule out pregnancy, STDs, and uterine pathology, then offer NSAIDs (5-7 days) or low-dose combined oral contraceptives (10-20 days) during bleeding days if treatment is desired. 2

Initial Assessment

• Approximately 34% of women experience infrequent spotting throughout implant use 2
• Unscheduled spotting or light bleeding is most common during the first year 2
• Bleeding changes do not indicate a medical problem and may or may not decrease with continued use 2

Systematic Evaluation Required

Rule out the following before attributing bleeding to the implant: 2

• Pregnancy - always evaluate first 2
• Medication interactions 2
• STDs 2
• New pathologic uterine conditions - polyps or fibroids 2

If any underlying problem is identified, treat or refer before attributing bleeding to the implant 2

Medical Treatment Options

If no underlying problem is found and the patient desires treatment: 2

• NSAIDs for 5-7 days during days of active bleeding 2
• Low-dose combined oral contraceptives for 10-20 days during bleeding days 2
• Estrogen alone for 10-20 days (if medically eligible) 2

Management of Amenorrhea with Implant

• Approximately 22% of implant users experience amenorrhea 3
• Amenorrhea requires no medical treatment—only reassurance 3
• Rule out pregnancy if regular bleeding pattern changes abruptly to amenorrhea 3
• No additional testing is required if amenorrhea is the only symptom 3

When to Consider Method Discontinuation

• If irregular bleeding persists despite treatment and the patient finds it unacceptable, counsel on alternative methods and offer another option 2
• Bleeding significantly impacts quality of life and is a valid reason for discontinuation 2

Critical Pitfalls to Avoid

• Never assume all bleeding is benign - always rule out pregnancy, STDs, and structural uterine pathology before attributing bleeding solely to the device 2
• Do not dismiss patient concerns - bleeding impacts quality of life and is a valid reason for method discontinuation if unacceptable 2
• Inadequate pre-insertion counseling is the most common mistake - discussing expected bleeding patterns before insertion reduces discontinuation rates 1, 2
• Do not use aspirin for Cu-IUD bleeding as it is ineffective or may worsen bleeding 1
