Medications for Heavy Menstrual Bleeding
NSAIDs and tranexamic acid are the most effective first-line medications for reducing heavy menstrual bleeding, with tranexamic acid showing superior efficacy in reducing blood loss by 26-60%. 1, 2
First-Line Treatment Options
NSAIDs
- NSAIDs like ibuprofen are effective for short-term treatment (5-7 days) of heavy menstrual bleeding 1
- They work by inhibiting prostaglandin synthesis, reducing uterine contractions and menstrual fluid prostaglandin levels 3
- NSAIDs have been shown to significantly reduce menstrual blood loss compared to placebo 1
- Standard dosing of ibuprofen (400mg three times daily) during days of bleeding can effectively reduce menstrual blood loss 3
Tranexamic Acid
- Tranexamic acid is a non-hormonal option that significantly reduces menstrual blood loss by 26-60%, making it more effective than NSAIDs 2, 4
- The recommended oral dosage is 3.9-4g/day for 4-5 days starting from the first day of the menstrual cycle 2
- Tranexamic acid works by inhibiting fibrinolysis, preventing fibrin degradation in the endometrium 4
- It significantly improves quality of life in women with heavy menstrual bleeding 5
- Important contraindication: tranexamic acid should not be used in women with active thromboembolic disease or history/risk of thrombosis 1, 2
Hormonal Options
Combined Oral Contraceptives
- Estrogen-progestin oral contraceptive pills effectively reduce bleeding symptoms and are considered first-line therapy 6, 7
- They provide the additional benefit of contraception while managing heavy bleeding 7
Progestin-Containing IUDs
- Levonorgestrel-releasing intrauterine devices (LNG-IUDs) are highly effective at reducing menstrual blood loss 1, 7
- Over time, bleeding generally decreases with LNG-IUD use, with many women experiencing only light menstrual bleeding or amenorrhea 1
- LNG-IUDs have been shown to reduce blood loss more effectively than tranexamic acid (96% reduction after 12 months) 4
Second-Line Treatment Options
GnRH Agonists and Antagonists
- For persistent heavy bleeding, GnRH agonists (e.g., leuprolide acetate) and oral GnRH antagonists (e.g., elagolix, linzagolix, relugolix) can be considered 1, 7
- These medications reduce bleeding symptoms and significantly decrease fibroid volume by 18-30% 7
- Side effects include hypoestrogenic effects (headaches, hot flushes, bone mineral density loss) 1
- Combination treatment with low doses of estrogen and progestin can mitigate these side effects 1
Treatment Algorithm for Heavy Menstrual Bleeding
Initial Assessment: Rule out underlying gynecological problems (e.g., fibroids, polyps, IUD displacement) 1
First-Line Treatment:
If First-Line Treatment Fails:
If Medical Management Fails:
- Consider surgical options or referral to specialist care 1
Important Considerations and Caveats
- Tranexamic acid has few adverse effects, mainly mild gastrointestinal symptoms 2, 4
- NSAIDs may cause gastric irritation, though ibuprofen shows less gastric irritation than aspirin 3
- For women with copper IUDs experiencing heavy bleeding, NSAIDs are particularly helpful 1
- Combination of treatments may be more effective than single agents for some women 8
- If bleeding persists despite treatment and is unacceptable to the patient, consider alternative contraceptive methods or referral for further evaluation 1
