Approach to selection of emergency contraception after unprotected intercourse
Approach to selection of emergency contraception after unprotected intercourse
UPI includes instances in which no contraception was used, a method was used imperfectly, or intercourse was forced without use of contraception.
UPI: unprotected intercourse; EC: emergency contraception; IUD: intrauterine device; BMI: body mass index; LNG: levonorgestrel; DMPA: depot medroxyprogesterone acetate; UPA: ulipristal acetate. * Pregnancy rates are 0.1% for the copper IUD, up to 1.8% for UPA, and up to 2.6% for LNG. ¶ Information on IUD device types, candidates, and device selection can be found in related UpToDate content. Δ Contraceptive failure can include missing more than one dose of oral contraceptive pills; failure to resume the DMPA injection, patch, or vaginal ring at the correct time; having a diaphragm, cervical cap, or contraceptive sponge slip; or having a condom break. ◊ Treatment with UPA requires a prescription. § After receiving EC, the patient can expect her period within three weeks. Patients who do not have a period after three weeks should perform a pregnancy test. ¥ For patients in the United States, oral LNG is available over-the-counter for individuals ages 17 and older. Individuals younger than age 17 may require a prescription, which varies by state.
