Key points:

• Intrauterine devices and implants are the most effective contraceptives at preventing pregnancy
• Non-barrier contraceptives do not protect against sexually transmitted infections
• Combined progestin-estrogen contraceptives are contraindicated in those with migraines, severe hypertension, severe liver disease, sickle cell disease, lupus, history of thromboembolism or stroke, and other diseases that increase the risk for thrombosis
• Emergency contraception includes oral ulipristal, oral levonorgestrel, and IUDs and should be taken with 72-120 hours after unprotected sexual intercourse. Only oral levonorgestrel is available without a prescription.
