Levonorgestrel works primarily by preventing ovulation, which is the release of an egg from the ovaries during the menstrual cycle. It does this by suppressing the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland, which are hormones that are necessary for ovulation to occur.Levonorgestrel also thickens the cervical mucus, making it more difficult for sperm to reach and fertilize an egg. In addition, it can make changes to the lining of the uterus, making it less receptive to implantation of a fertilized egg.

As an emergency contraceptive, levonorgestrel can be taken within 72 hours of unprotected sex to help prevent pregnancy. When taken as directed, it is highly effective in reducing the risk of pregnancy. However, it is important to note that it is not effective in preventing sexually transmitted infections (STIs), and should not be used as a regular form of birth control.
