Review the following four patient profiles. Each patient is seeking a reliable method of contraception. Match each clinical scenario with the most medically appropriate contraceptive method based on the United States Medical Eligibility Criteria (US MEC) for Contraceptive Use.
- A 35-year-old woman with active estrogen receptor-positive breast cancer currently undergoing adjuvant tamoxifen therapy.Copper T380A intrauterine device
- A 29-year-old woman with a history of a Roux-en-Y gastric bypass procedure two years ago, who reports severe baseline dysmenorrhea and heavy menstrual bleeding.Levonorgestrel-releasing intrauterine system
- A 24-year-old woman taking phenytoin for generalized tonic-clonic seizures, who requests a highly effective, non-daily, non-intrauterine hormonal contraceptive.Depot medroxyprogesterone acetate injection
- A 38-year-old woman who smokes 20 cigarettes per day and specifically requests a daily oral contraceptive.Progestin-only oral pill
Answer
The breast cancer patient receives the Copper IUD; the bariatric surgery patient receives the Levonorgestrel IUS; the patient on phenytoin receives the DMPA injection; and the 38-year-old smoker receives the Progestin-only pill.
Each assignment rigorously adheres to the US MEC guidelines. The Copper IUD avoids hormone exposure in active breast cancer; the LNG-IUS bypasses gastric malabsorption while treating dysmenorrhea; the DMPA injection provides sufficient hormone levels to overcome hepatic enzyme induction by phenytoin; and the progestin-only pill provides a requested oral method while avoiding the severe cardiovascular risks of estrogen in older smokers.

Key Concept
Application of the US Medical Eligibility Criteria (MEC) for Contraceptive Use in patients with complex medical comorbidities, including malignancy, malabsorption, enzyme-inducing medications, and cardiovascular risk factors.
