What is Levonorgestrel?

Levonorgestrel is a progestin and has effects similar to those of the hormone progesterone. It works mostly by preventing ovulation and closing off the cervix to prevent the passage of sperm.

Levonorgestrel is a hormonal medication which is used in a number of birth control methods. In pill form, sold under the brand name Plan B among others, it is useful within 120 hours as emergency birth control.[2] It becomes less effective the longer after sex and only works before pregnancy has occurred. It is also combined with an estrogen to make combined oral birth control pills. Within an intrauterine device (IUD), sold as Mirena among others, it is effective for long-term prevention of pregnancy.

Levonorgestrel Usage

Levonorgestrel is used by women to prevent pregnancy after birth control failure (such as a broken condom) or unprotected sex. This medication is an emergency contraceptive and should not be used as a regular form of birth control. It is a progestin hormone that works mainly by preventing the release of an egg (ovulation) during your menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and changes the lining of the uterus (womb) to prevent attachment of a fertilized egg.


Levonorgestrel Side Effects

After intake of 1.5 mg levonorgestrel in clinical trials, very common side effects (reported by 10% or more) included: hives, dizziness, headache, nausea, abdominal pain, uterine pain, delayed menstruation, heavy menstruation, uterine bleeding, and fatigue; common side effects (reported by 1% zu 10%) included diarrhea, vomiting, and painful menstruation; these side effects usually disappeared within 48 hours
