When you need emergency contraception, the quickest way to stop an unwanted pregnancy is to use a method that works after sex. Emergency contraception is a short‑term, high‑dose hormonal or device‑based approach taken within days of unprotected intercourse. It’s designed to prevent fertilization or implantation. Also known as post‑coital birth control, it gives you a backup when your regular method fails or you didn’t use one. This topic covers everything from over‑the‑counter pills to prescription options and even a copper IUD, so you can pick the right choice for your situation.
One of the most widely available pills is levonorgestrel, often recognized by the brand name Plan B. Levonorgestrel is a synthetic progestin that mainly works by delaying ovulation. When taken within 72 hours, it can reduce the chance of pregnancy by up to 89 %. Its over‑the‑counter status makes it a go‑to option for many people, but timing is critical – the sooner you take it, the better the protection. If you need a longer window, ulipristal acetate (brand name Ella) offers up to five days of effectiveness. Ulipristal acetate is a selective progesterone receptor modulator that blocks the hormone surge that triggers ovulation. Clinical studies show it remains highly effective even on day 4 or 5 after intercourse. Because it requires a prescription, you’ll usually get it from a pharmacy after a short consultation.
For those who want the most reliable, long‑lasting backup, the copper intrauterine device (IUD) is a top choice. Copper IUD works by creating an inflammatory environment in the uterus that is toxic to sperm and eggs, preventing fertilization and implantation. Inserted by a healthcare professional within five days of unprotected sex, it offers over 99 % effectiveness and continues as a regular birth‑control method for up to ten years. While the insertion requires a clinic visit, many users appreciate the dual benefit of emergency protection plus ongoing contraception.
All three methods share a common requirement: they must be used as soon as possible after intercourse to maximize effectiveness. Side effects are generally mild – such as nausea, headache, or temporary spotting – and disappear quickly. If you have underlying health conditions, are taking other medications, or are unsure which option fits you best, a brief chat with a pharmacist or clinician can clear up doubts. Below you’ll find a curated set of articles that dive deeper into each option, compare costs, explain how to order safely online, and answer the most common questions about timing, side effects, and follow‑up care. Explore them to find the answer that matches your needs.
