Levonorgestrel Postinor 1

Learn about Levonorgestrel Postinor 1, a popular emergency contraceptive pill. Find out how it works, its effectiveness, and possible side effects.

Levonorgestrel Postinor 1 is a type of emergency contraceptive pill commonly known as the morning-after pill. It is used to prevent unwanted pregnancies after unprotected sex or contraceptive failure. The pill contains a synthetic hormone called levonorgestrel, which works by delaying ovulation or preventing fertilization of an egg.

How does Levonorgestrel Postinor 1 work?

Levonorgestrel Postinor 1 works by preventing or delaying ovulation. Ovulation is the release of an egg from the ovary, which happens once every menstrual cycle. By delaying ovulation, the pill makes it less likely for sperm to fertilize an egg. If fertilization has already occurred, the pill may prevent the fertilized egg from implanting in the uterus.

How effective is Levonorgestrel Postinor 1?

Levonorgestrel Postinor 1 is most effective when taken within 72 hours (3 days) of unprotected sex or contraceptive failure. It is about 95% effective in preventing pregnancy if taken within 24 hours of unprotected sex. However, the effectiveness decreases the longer you wait to take the pill. It is important to note that Levonorgestrel Postinor 1 does not protect against sexually transmitted infections (STIs).

What are the possible side effects of Levonorgestrel Postinor 1?

Common side effects of Levonorgestrel Postinor 1 include nausea, vomiting, fatigue, headaches, and menstrual changes. These side effects usually go away on their own within a few days. If you experience severe abdominal pain, dizziness, or heavy bleeding, seek medical attention immediately.

Who should not take Levonorgestrel Postinor 1?

Levonorgestrel Postinor 1 is not recommended for women who are pregnant or breastfeeding. It is also not recommended for women who have a history of blood clots, liver disease, or certain types of cancer. If you are taking any medications, including herbal supplements or over-the-counter drugs, consult your healthcare provider before taking Levonorgestrel Postinor 1.

Conclusion

Levonorgestrel Postinor 1 is a safe and effective emergency contraceptive pill that can prevent unwanted pregnancies if taken within 72 hours of unprotected sex or contraceptive failure. It works by delaying ovulation or preventing fertilization of an egg. While it may cause some side effects, they are usually mild and go away on their own. However, it is important to consult your healthcare provider before taking Levonorgestrel Postinor 1, especially if you have any medical conditions or are taking any medications.
