Levonorgestrel is a progestin. Progestins are hormones used in many birth control pills. Although levonorgestrel and similar emergency contraception pills contain a higher dose of levonorgestrel than birth control pills, they work in a similar way to prevent pregnancy, mainly by stopping the release of an egg from the ovary Levonorgestrel emergency contraceptive side effects.

Clinical significance. Levonorgestrel is twice as potent as, and more commonly used than, norgestrel. Primarily, the documented side effects mentioned here are all for levonorgestrel. Alder et al (1995) reported 57 cases of intracranial hypertension or papilledema from a spontaneous reporting system and there are an additional 70 cases known to the manufacturer (Weber et al 1995), all possibly. Levonorgestrel has an array of contraceptive actions: thickening of the cervical mucus, inhibiting sperm survival and motility, suppression of the endometrium, and for some people, anovulation due to systemic absorption of levonorgestrel. The three LNG containing IUDs available at University Health Services are Mirena, Kyleena and Skyla Levonorgestrel is the levorotatory form of norgestrel and synthetic progestogen with progestational and androgenic activity. Levonorgestrel binds to the progesterone receptor in the nucleus of target cells, thereby stimulating the resulting hormone-receptor complex, initiating transcription, and increasing the synthesis of certain proteins. This results in a suppression of luteinizing hormone. With the progestogen-only intra-uterine device, levonorgestrel is released close to the site of the main contraceptive action (on cervical mucus and endometrium) and therefore progestogenic side-effects and interactions are less likely; in particular, enzyme-inducing drugs are unlikely to significantly reduce the contraceptive effect of the progestogen-only intra-uterine system and additional contraceptive precautions are not required
Once bound to the receptor, progestins like levonorgestrel will slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH (luteinizing hormone) surge. Loss of the LH surge inhibits ovulation and thereby prevents pregnancy Levonorgestrel is well-absorbed from the gastrointestinal tract and is extensively bound to plasma proteins (97 to 99%), including albumin and sex hormone binding globulin Kuhnz et al. (1995). It is not subject to first-pass hepatic metabolism and is around 100% bioavailable Goldzieher (1989) Levonorgestrel-releasing intrauterine system is a device that contains the female hormone, levonorgestrel. It is placed in the uterus (womb) where it slowly releases the hormone to prevent pregnancy for up to 3 years for Skyla®, up to 5 years for Kyleena™, or up to 6 years for Liletta® or Mirena®
Our previous study indicated that emergency contraception, including levonorgestrel and progesterone, could lead to ectopic pregnancy following contraception failure. However, our understanding of the effects of levonorgestrel and progesterone on oviductal physiology is limited. The receptivity of the fallopian tubal epithelium after levonorgestrel and progesterone treatment was examined. IUD delivers approximately 14 mcg/day of levonorgestrel after 24 days. This rate decreases progressively to approximately 6 mcg/day after 1 year and to 5 mcg/day after 3 years. The average in vivo release rate of LNG is approximately 8 mcg/day over the first year of use and 6 mcg/day over a period of 3 years After an 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% to 10%) included diarrhea, vomiting, and painful menstruation; these side effects usually disappeared within 48 hours • Possible side effects of Levonorgestrel 1.5 mg tablets You might feel sick, have tender breasts, headaches, tummy pain, diarrhea, feel dizzy or tired after taking Levonorgestrel 1.5 mg tablets.

Levonorgestrel is not effective once the process of implantation has begun. Clinical efficacy and safet Methods We evaluated the effects of a 2-mg/kg dose of levonorgestrel and quinestrol and a 1:1 mixture of the two (EP-1) on reproductive behavior as well as changes in the reproductive system, reproductive hormone levels, and toxicity in Brandt's voles Objective: The objective of this study was to compare the effects of the levonorgestrel-releasing intrauterine system (LNG-IUS) with those of systemic progestogen in perimenopausal and postmenopausal women taking systemic estrogen therapy (ET). Methods: We searched Medline (August 8, 2009), Embase (August 8, 2009), the Cochrane Central Register of Controlled Trials on the Cochrane Library.
