What non‑hormonal treatments are available for managing heavy menstrual bleeding (menorrhagia)?

Non-Hormonal Options for Heavy Menstrual Bleeding

Tranexamic acid is the most effective non-hormonal medication for heavy menstrual bleeding, demonstrating consistent 26-54% reductions in menstrual blood loss with improvement in quality of life. 1, 2

First-Line Non-Hormonal Medical Options

Tranexamic Acid (Antifibrinolytic Agent)

• Most effective non-hormonal option with the greatest mean reductions in menstrual blood loss among all non-hormonal medications 1
• Reduces bleeding by 26-54% in women with heavy menstrual bleeding 2
• Superior to NSAIDs for menstrual bleeding reduction 2
• Well-tolerated with documented improvement in health-related quality of life 1
• Works by inhibiting fibrinolysis, stabilizing clot formation in the endometrium 3

NSAIDs (Nonsteroidal Anti-Inflammatory Drugs)

• Second-line non-hormonal option - less effective than tranexamic acid 2, 4
• Reduce menstrual blood loss by 10-52% 2
• Mefenamic acid is the most commonly studied NSAID for this indication 4, 3
• More effective than placebo but less effective than tranexamic acid, danazol, or levonorgestrel IUS 4
• Additional benefit: reduces dysmenorrhea (menstrual cramping) 4
• Work by reducing elevated prostaglandin levels in the endometrium 4

Non-Hormonal Procedural Options

When medical management fails or is contraindicated, several non-hormonal procedural interventions are available, particularly for women with fibroids:

Uterine Artery Embolization (UAE)

• Highly effective minimally invasive option for heavy menstrual bleeding, especially with fibroids 5
• Reduces menstrual bleeding with average fibroid size decrease >50% at 5 years 5
• Superior to MR-guided focused ultrasound with better symptom relief, quality of life, and lower reintervention rates 5
• Lower reintervention rate (13% at 2 years) compared to MRgFUS (30%) 5
• Shorter procedure time (2.3 hours vs 6.75 hours for MRgFUS) 5
• Pregnancy remains possible after UAE 5

Endometrial Ablation

• Destroys the endometrial lining to reduce or eliminate menstrual bleeding 6
• Not first-line but appropriate for women who have completed childbearing 6
• Less effective in presence of adenomyosis 5
• Important caveat: Not suitable for women desiring future fertility

Myomectomy (Surgical Fibroid Removal)

• For women with fibroids causing heavy bleeding who wish to preserve fertility 5
• Can be performed hysteroscopically (for submucosal fibroids), laparoscopically, or via open surgery 5
• Laparoscopic approach offers shorter hospital stays and faster recovery than open surgery 5
• Pregnancy remains possible after myomectomy 5

MR-Guided Focused Ultrasound (MRgFUS)

• Non-invasive thermal ablation of fibroids 5
• Associated with higher reintervention rates (30% at 2 years) and less symptom control compared to UAE 5
• Longer procedure time and occasionally requires two days 5
• Lower major adverse event rate (0.2%) compared to surgical approaches (12.6%) 5

Clinical Algorithm for Non-Hormonal Management

Step 1: Initial Medical Management

• Start with tranexamic acid as first-line non-hormonal medication
• Add or substitute NSAIDs (mefenamic acid) if dysmenorrhea is prominent or tranexamic acid is contraindicated
• Both can be used together for additive effect

Step 2: Evaluate for Structural Causes

• If medical management fails, investigate with imaging (transvaginal ultrasound, saline infusion sonohysterography) or hysteroscopy 6
• Identify fibroids, polyps, adenomyosis, or other structural abnormalities

Step 3: Procedural Interventions (if medical management fails)

• For submucosal fibroids: Hysteroscopic myomectomy 5
• For intramural/subserosal fibroids with no fertility concerns: UAE (preferred) or MRgFUS 5
• For fibroids with fertility preservation desired: Laparoscopic or open myomectomy 5
• For no structural abnormalities and completed childbearing: Endometrial ablation 6

Step 4: Address Iron Deficiency

• Screen all women with heavy menstrual bleeding for anemia and iron deficiency 7, 8
• Oral iron is first-line for iron deficiency/anemia 8
• Intravenous iron for severe anemia, non-responders, or before surgery 8

Important Caveats

Common Pitfalls to Avoid:

• Don't overlook screening for bleeding disorders, especially von Willebrand disease, particularly in adolescents with heavy menstrual bleeding 9
• Endometrial ablation has reduced efficacy in adenomyosis 5
• Medical management should be trialed before pursuing invasive therapies 5
• UAE and ablative procedures require counseling about fertility implications, though pregnancy remains possible 5

Quality of Life Considerations:

• Heavy menstrual bleeding significantly impacts work/school attendance and cognitive function 7
• Iron deficiency, even without anemia, adversely affects daily quality of life 7
• Tranexamic acid specifically demonstrates improvement in health-related quality of life measures 1
