Levonorgestrel BP: What It Is, How to Use It & What to Expect

If you’ve ever needed a backup plan after unprotected sex, you’ve probably heard of Levonorgestrel. It’s the active ingredient in many over‑the‑counter “morning‑after” pills and is listed on our site as Levonorgestrel BP. In plain English, it’s a synthetic hormone that can stop an egg from being fertilized or prevent it from implanting if you’ve already become pregnant.

The "BP" part stands for the British Pharmacopoeia – a set of standards that ensures the drug meets quality and safety rules. That means the tablets you buy in pharmacies should contain the right amount of Levonorgestrel, no more, no less. Knowing this helps you trust what’s on the label.

How to Take Levonorgestrel BP

You only need one dose, taken as soon as possible after intercourse – ideally within 72 hours. The sooner, the better: effectiveness drops from about 95% in the first 24 hours to around 58% at three days.

Most products come in a single tablet of 1.5 mg. Swallow it with water; you don’t need food or special timing. If you vomit within two hours, repeat the dose with a new tablet because your body may not have absorbed the medication.

Common Side Effects and When to Seek Help

After taking Levonorgestrel BP, many people feel mild nausea, headache, or fatigue. Spotting (light bleeding) can happen, especially if you’re close to your next period. These symptoms usually fade in a day or two.

If you get severe abdominal pain, heavy bleeding, or signs of an allergic reaction – like rash, swelling, or trouble breathing – call a doctor right away. Those are rare but need medical attention.

Remember, Levonorgestrel BP doesn’t protect against STIs and isn’t meant for regular birth control. If you find yourself needing it often, talk to a healthcare provider about longer‑term options such as the pill, patch, or IUD.

Where can you get it? Most pharmacies stock Levonorgestrel BP without a prescription in many countries. Online drugstores also sell it, but make sure they’re reputable – check for a valid license and read customer reviews. Our site links to trusted sources where you can compare prices and delivery times.

Finally, keep track of your next menstrual cycle. Your period may arrive a few days early or late; this is normal after taking emergency contraception. If it’s more than a week late, take a pregnancy test to be sure.

Levonorgestrel BP is a safe, effective backup when used correctly. Knowing how it works, the right timing, and possible side effects empowers you to make quick decisions and stay in control of your reproductive health.
