The CDC US Medical Eligibility Criteria (US MEC) is the evidence based framework NPs use to determine contraceptive safety for patients with specific medical conditions.
The CDC US Medical Eligibility Criteria (US MEC) is the evidence-based framework NPs use to determine contraceptive safety for patients with specific medical conditions. The US MEC categorizes each combination of medical condition and contraceptive method into four categories: Category 1 (no restriction), Category 2 (advantages generally outweigh risks), Category 3 (theoretical or proven risks usually outweigh advantages), and Category 4 (unacceptable health risk). The framework addresses conditions affecting estrogen safety (VTE risk, cardiovascular disease, migraine with aura), conditions affecting IUD use (pelvic infection, uterine anomalies), and conditions requiring special consideration (breastfeeding, postpartum timing, drug interactions).
