A 32-year-old multiparous woman with menorrhagia and dysmenorrhea seeks long-acting reversible contraception. She has no contraindications to hormonal methods. Which IUCD is the drug of choice for her presentation?

Explanation

## Clinical Scenario Analysis The patient presents with two key features: - **Menorrhagia** (heavy menstrual bleeding) - **Dysmenorrhea** (painful periods) - Desire for long-acting reversible contraception (LARC) ## Why LNG-IUS is the Correct Choice **Key Point:** The levonorgestrel-releasing IUCD (LNG-IUS) is the drug of choice for women with menorrhagia and dysmenorrhea who need contraception, because it provides dual therapeutic benefit: contraception AND treatment of the underlying menstrual pathology. ## Mechanism of Benefit 1. **Endometrial suppression**: LNG-IUS releases 20 μg/day of levonorgestrel directly into the uterine cavity, causing: - Endometrial atrophy and decidualization - Reduced endometrial proliferation - Decreased prostaglandin production (reduces dysmenorrhea) 2. **Menstrual reduction**: Achieves 90% reduction in menstrual blood loss over 12 months 3. **Dysmenorrhea relief**: Marked improvement in pain due to reduced prostaglandins and decreased uterine contractility ## Comparison Table: IUCD Types in Menorrhagia | Feature | Copper T 380A | LNG-IUS | Copper T 200 | Progesterone-IUS | | --- | --- | --- | --- | --- | | **Menorrhagia** | Worsens (↑ bleeding 20–30%) | Improves (↓ 90%) | Worsens | Improves | | **Dysmenorrhea** | No benefit | Improves significantly | No benefit | Improves | | **Contraceptive efficacy** | 99.2% | 99.8% | 98% | 98% | | **Duration** | 10 years | 5–7 years | 3 years | 1 year | | **Ideal for menorrhagia** | No | **Yes** | No | No | **High-Yield:** LNG-IUS is the ONLY IUCD that improves both menorrhagia AND dysmenorrhea. Copper IUCDs typically worsen bleeding and are contraindicated in menorrhagia. ## Clinical Pearl Women with menorrhagia who choose copper IUCDs often discontinue them due to worsening bleeding. LNG-IUS not only provides contraception but also serves as a therapeutic intervention, making it the preferred choice in this scenario. **Mnemonic:** **LNG-IUS = Lighter, Nicer, Gentler** (reduced bleeding, improved comfort, therapeutic benefit).
