Is it safe to insert an Intrauterine Device (IUD) during a heavy menstrual period?

IUD Insertion During Heavy Menstrual Period

Yes, it is safe to insert an intrauterine device (IUD) during a heavy menstrual period, and in some cases, it may even be advantageous. 1

Safety and Benefits of IUD Insertion During Menstruation

• IUDs can be safely inserted at any time during the menstrual cycle, including during heavy menstrual flow 2, 1
• The copper T 380A IUD specifically can be inserted in non-pregnant women at any time in the menstrual cycle 3
• Potential advantages of insertion during menstruation:
  • Ensures the woman is not pregnant
  • The cervical os may be more dilated, potentially making insertion easier
  • Bleeding from the insertion procedure blends with menstrual bleeding

Considerations for Different Types of IUDs

Copper IUD

• Can be inserted at any time during the menstrual cycle with no backup contraception needed 1
• May increase menstrual bleeding, which is the main side effect of the copper T 380A IUD 3
• NSAIDs can reduce menstrual blood loss by 26-60% when used for 5-7 days during bleeding days for copper IUD users experiencing heavy bleeding 1

Levonorgestrel-releasing IUDs (LNG-IUDs)

• The prescribing information recommends insertion during the first seven days of menses 3
• Requires backup contraception for 7 days if inserted >7 days after menses started 1
• May actually help reduce heavy menstrual bleeding over time, making it a therapeutic option for women with menorrhagia 1

Risks to Consider

Expulsion Risk

• Heavy menstrual bleeding is associated with a greater risk of IUD expulsion (aHR 2.84,95% CI 2.66-3.03) 4
• Women should be counseled about this increased risk and taught how to check for IUD strings

Perforation Risk

• The absolute risk of uterine perforation is low overall (0.21% at 1 year) 4
• Heavy menstrual bleeding is associated with a slightly elevated perforation risk 4
• Proper insertion technique with bimanual examination and cervical inspection before insertion is essential 1

Management of Bleeding After Insertion

• Unscheduled spotting or light bleeding, as well as heavy or prolonged bleeding, is common during the first 3-6 months of Cu-IUD use 2
• For women who experience problematic bleeding with a copper IUD, NSAIDs for short-term treatment (5-7 days) during days of bleeding can be effective 2, 5
• If bleeding persists and is unacceptable to the woman, consider alternative contraceptive methods 2

Clinical Approach

1. Perform bimanual examination and cervical inspection before insertion 1
2. Ensure the woman is not pregnant
3. Counsel about expected changes in bleeding patterns:
   • For copper IUD: Potential increase in menstrual bleeding
   • For LNG-IUD: Initial irregular bleeding that typically improves over time
4. Provide information about the slightly increased risk of expulsion with heavy menstrual bleeding
5. Teach the woman how to check for IUD strings
6. Schedule follow-up if needed, though routine follow-up visits are not required 1

Common Pitfalls to Avoid

• Delaying IUD insertion unnecessarily when reasonably certain the woman is not pregnant 1
• Requiring unnecessary examinations or tests before initiating contraception 1
• Failing to counsel about expected bleeding changes and management options 2
• Not discussing the slightly increased risk of expulsion with heavy menstrual bleeding 4

In summary, IUD insertion during heavy menstrual bleeding is safe and may be convenient for both the provider and patient. The benefits of immediate contraceptive protection generally outweigh the slightly increased risk of expulsion.
