A 28-year-old woman attends the family planning clinic requesting oral contraception. She has a history of migraine with aura, occurring 2–3 times per month, typically preceded by visual disturbances and photophobia. Her blood pressure is 118/76 mmHg, BMI 22 kg/m², and general examination is unremarkable. She is otherwise healthy with no other medical comorbidities. Which of the following is the most appropriate contraceptive choice for this patient?

Explanation

## Clinical Scenario Analysis This patient has **migraine with aura**, which is a critical contraindication to combined oral contraceptive pills (COCPs) containing estrogen. The presence of aura indicates cortical spreading depression, which increases the risk of ischemic stroke when combined with estrogen-induced hypercoagulability. ## Key Contraindication **Key Point:** Migraine with aura is an absolute contraindication (WHO Category 4) to estrogen-containing contraceptives, regardless of estrogen dose. The aura itself is the red flag, not the migraine frequency. **High-Yield:** The distinction is critical: - **Migraine WITHOUT aura** → COCPs acceptable (WHO Category 2) - **Migraine WITH aura** → COCPs contraindicated (WHO Category 4) ## Suitable Alternatives | Contraceptive Method | Suitability in Migraine with Aura | Reason | |---|---|---| | Copper IUD | ✓ Safe | No systemic hormones; no thrombotic risk | | Progestin-only pill | ⚠ Relative caution | Minimal estrogen effect, but less effective; not ideal first-line | | COCP (any dose) | ✗ Contraindicated | Estrogen increases stroke risk in migraine with aura | | Progestin-only implant | ✓ Safe | No estrogen; highly effective | | Progestin-only injection | ✓ Safe | No estrogen; highly effective | ## Why Copper IUD is Best 1. **No hormonal component** → eliminates thrombotic and stroke risk 2. **Highly effective** (>99% efficacy) → comparable to COCP 3. **Long-acting reversible** → convenient for this age group 4. **No drug interactions** → safe with any concurrent medications **Clinical Pearl:** The WHO Medical Eligibility Criteria (MEC) explicitly place migraine with aura in Category 4 (unacceptable risk) for estrogen-containing methods. This is one of the few absolute contraindications to COCPs in an otherwise healthy young woman. [cite:WHO MEC 2015; NFSG Guidelines]
