Levonorgestrel is a synthetic hormone commonly used in emergency contraception pills, such as Plan B, to prevent pregnancy after unprotected sex or contraceptive failure. It works by preventing ovulation, fertilization, or implantation of a fertilized egg in the uterus.

It is important to note that Levonorgestrel should not be used as a regular form of contraception and is intended for emergency use only. It is not effective in terminating an existing pregnancy and should not be used as an abortion pill.

When taken as directed within 72 hours of unprotected sex, Levonorgestrel is highly effective in preventing pregnancy. However, it is most effective when taken as soon as possible after intercourse. It is available over-the-counter without a prescription for individuals of all ages.

Like any medication, Levonorgestrel may cause side effects in some individuals. Common side effects include nausea, vomiting, fatigue, headache, and breast tenderness. These side effects are usually mild and temporary.

It is important to consult with a healthcare provider before taking Levonorgestrel, especially if you have any underlying medical conditions or are taking other medications. Your healthcare provider can provide guidance on the appropriate use of Levonorgestrel and answer any questions you may have.

In conclusion, Levonorgestrel is a safe and effective option for emergency contraception when used correctly. It is important to be informed about how to use it properly and to seek medical advice if needed. Remember, emergency contraception should not be used as a regular form of birth control.
