Levonorgestrel Uses

Levonorgestrel is used for emergency contraception. It provides a safe and effective way to prevent an unintended pregnancy after unprotected sex or contraceptive failure.

How Levonorgestrel works

Levonorgestrel is a progestin (female hormones). It works to prevent pregnancy by temporarily stopping the release of an egg from the ovary, or preventing fertilization (union) of the egg by sperm. It may also alter the lining of the uterus (womb) to stop a fertilized egg from attaching to the uterus.

Q. Can Levonorgestrel protect against Sexually Transmitted Disease (STDs) and HIV / AIDS?

No, it does not offer any protection from HIV / AIDS or other Sexually Transmitted Disease (STDs). You can use condoms to protect yourself from STDs and HIV / AIDS.

Q. What is the difference between 'emergency contraceptive pill' and 'abortion pill'?

Pregnancy starts once the fertilized egg gets attached to the lining of the uterus (womb). Abortion pills contain medicine, which hinders the development of a pregnancy after it has occurred and also alters the character of the womb lining in a way that the fertilized egg gets detached, hence causing abortion. On the other hand, emergency contraceptive pills like Levonorgestrel contain female hormones which delay the release of egg or prevent movement of sperm towards the egg. This prevents fertilization and hence pregnancy. Levonorgestrel does not have any effect on a fertilized egg and hence does not cause abortion.

Q. Is Levonorgestrel effective if frequent acts of intercourse have occurred in a short duration of time?

Yes. It is effective if you have had several acts of intercourse in a short span of time. However, it is important that these acts have occurred within 72 hours before taking Levonorgestrel. Also, since there is a chance of unintended pregnancy after frequent acts of unprotected sex in the same cycle, it is advisable to use a barrier contraceptive method (e.g. condom) until the next period even after using Levonorgestrel.
