Levonorgestrel: What You Need to Know

Levonorgestrel is a hormone commonly used in emergency contraception and birth control pills. It helps prevent pregnancy when taken shortly after unprotected sex by stopping or delaying ovulation. Understanding how it works and when to use it can help you make better choices about your reproductive health.

This medication is most effective when taken as soon as possible after unprotected intercourse—ideally within 72 hours. The sooner you take it, the better it can prevent pregnancy. However, it doesn’t work if you’re already pregnant and won’t terminate an existing pregnancy.

Common Uses and How to Take Levonorgestrel

Levonorgestrel is often found in emergency contraceptive pills like Plan B or as part of some regular birth control methods. For emergency use, it’s a one or two-dose medication you take orally. It’s important to follow the instructions on the package or from your healthcare provider carefully.

Besides emergency contraception, Levonorgestrel is also included in intrauterine devices (IUDs) for long-term birth control, releasing a small, steady amount of hormone within the uterus. This method has a very different use case and schedule but relies on the same hormone principles.

What You Should Watch Out For

Levonorgestrel is generally safe, but some people experience side effects like nausea, headache, fatigue, or changes in their next period. These usually go away quickly. If you repeatedly need emergency contraception, it might be time to talk with a healthcare provider about a more regular birth control method.

Remember, Levonorgestrel doesn’t protect against sexually transmitted infections (STIs). Using condoms remains the best way to protect yourself beyond preventing pregnancy.

If you have any medical conditions or take other medicines, check with your doctor or pharmacist before using Levonorgestrel. Certain medications can lower its effectiveness. Also, it’s not recommended for use as regular contraception—it’s meant for emergencies.

Knowing how and when to use Levonorgestrel can make all the difference in managing your reproductive health safely and effectively. Don’t hesitate to reach out to medical professionals for advice tailored specifically to your situation.
