Emergency Contraception: Quick Answers for Unexpected Situations

When you hear the term Emergency contraception, a short‑term, hormone‑based or device method used after unprotected sex to prevent pregnancy. Also known as EC, it steps in when regular birth control fails or isn’t used. Emergency contraception works by delaying ovulation, thickening cervical mucus, or altering the uterine lining so a fertilized egg can’t implant. The key factor is timing—most options lose effectiveness after 72 hours, though some still work up to five days. Knowing what’s available, how they differ, and when to take them makes the difference between a calm conversation with your doctor and a rushed pharmacy visit. Below we break down the science, the choices, and the practical points you’ll need to decide fast.

What Types Exist and How Do They Compare?

There are three widely accepted forms of emergency contraception: the levonorgestrel pill, the ulipristal acetate tablet, and the copper intrauterine device. Each has its own profile of efficacy, timing, and side‑effects. Levonorgestrel, a synthetic progestin sold over the counter in many countries is the most familiar. It blocks or delays ovulation if taken within 72 hours and reduces pregnancy risk by about 75 % when used promptly. Its dosage is usually 1.5 mg taken as a single dose or two 0.75 mg pills 12 hours apart. Ulipristal acetate, a selective progesterone receptor modulator that can be prescribed up to five days after intercourse works a bit longer because it can inhibit ovulation even after the LH surge begins. Studies show a 85 % reduction in pregnancy risk when taken within 120 hours, making it the most reliable oral option for delayed use. The third option, the copper IUD, is a non‑hormonal device inserted by a clinician within five days of unprotected sex. It creates an inflammatory reaction toxic to sperm and eggs, offering over 99 % effectiveness and continuing protection for up to ten years. Semantic connections emerge: Emergency contraception encompasses oral pills like levonorgestrel and ulipristal acetate, while copper IUDs provide a durable, device‑based method; timing influences effectiveness of each, and the choice often depends on access and personal health factors.

Beyond the core methods, practical considerations shape which option works best for you. Levonorgestrel is available OTC, making it the quickest pick‑up, but its efficacy drops sharply after the first 24 hours. Ulipristal acetate requires a prescription in some regions, yet it maintains high effectiveness through the full five‑day window, and it isn’t affected by body weight as much as levonorgestrel. Copper IUD insertion demands a clinic visit, so it’s ideal for those who can schedule an appointment and want long‑term contraception without hormones. Side‑effects vary: levonorgestrel may cause mild nausea or fatigue, ulipristal can lead to headache or menstrual changes, and the copper IUD might cause heavier periods or cramping initially. Drug interactions matter too—certain anticonvulsants and herbal supplements can lower pill efficacy, while copper IUDs have no known pharmacologic interactions. Understanding these nuances helps you match the method to your lifestyle, health profile, and how soon you need protection.
