Description: Levonorgestrel is a hormone which is similar to the hormoneprogesterone that is produced by the body. It is used to prevent women from becoming pregnant. It works by increasing the thickness of vaginal fluid which can stop a sperm from reaching an egg. It also changes the lining of the uterus which makes it difficult for an egg to develop.

Levonorgestrel may increase the chances of developing breast cancer. You and your prescriber will need to weigh up the benefits and risks of taking Levonorgestrel before you start to take it. Women who take Levonorgestrel need to regularly examine their breasts for any changes or lumps.

The primary mechanism of action of levonorgestrel as a progestogen-only emergency contraceptive pill is, according to FIGO, to prevent fertilization by inhibition of ovulation.

Applications: Levonorgestrel is used in women to prevent pregnancy after birth control failure (e.g., broken condom) or unprotected sex.

It is a progestin hormone that prevents pregnancy by preventing the release of an egg (ovulation) and changing the womb and cervical mucus to make it more difficult for an egg to meet sperm (fertilization) or attach to the wall of the womb (implantation).

Using this medication will not stop an existing pregnancy or protect you against sexually transmitted diseases (e.g., HIV, gonorrhea, chlamydia).
