Levonorgestrel Common side effects include nausea, breast tenderness, headaches, and increased, decreased, or irregular menstrual bleeding. When used as a form of emergency contraception, if pregnancy occurs, there is no evidence its use harms the baby. It is safe to use during breastfeeding. Birth control that contains levonorgestrel will not change the risk of sexually transmitted infections. It works mostly by decreasing ovulation and closing off the cervix to prevent the passage of sperm.
Levonorgestrel The primary mechanism of action of levonorgestrel as a progestogen-only emergency contraceptive pill is, according to International Federation of Gynecology and Obstetrics (FIGO), to prevent fertilization by inhibition of ovulation and thickening of cervical mucus. FIGO has stated that: "review of the evidence suggests that LNG [levonorgestreol] ECPs cannot prevent implantation of a fertilized egg. Language on implantation should not be included in LNG ECP product labeling." In November 2013, the European Medicines Agency (EMA) approved a change to the label saying it cannot prevent implantation of a fertilized egg.
Levonorgestrel Other studies still find the evidence to be unclear. While it is unlikely that emergency contraception affects implantation it is impossible to completely exclude the possibility of post-fertilization effect.
Levonorgestrel Its "in vitro" relative binding affinities at human steroid hormone receptors are: 323% that of progesterone at the progesterone receptor, 58% that of testosterone at the androgen receptor, 17% that of aldosterone at the mineralocorticoid receptor, 7.5% that of cortisol at the glucocorticoid receptor, and <0.02% that of estradiol at the estrogen receptor.
Levonorgestrel Levonorgestrel is a manufactured hormone 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. 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 pill. Within an IUD, sold as Mirena among others, it is effective for long term prevention of pregnancy. An implantable form of levonorgestrel is also available in some countries.
Levonorgestrel Levonorgestrel was first made in the 1960s and its use as a method of birth control began in the 1980s. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. It is available as a generic medication. The wholesale cost in the developing world costs between 0.23 and 1.65 USD for the dose required for emergency birth control. In the United States it is over the counter for all ages.
Levonorgestrel At very low daily dose of 30 µg, levonorgestrel is used in some progestogen only pill
Levonorgestrel After intake of levonorgestrel 1.5 mg in clinical trials, very common effects (reported by 10% or more) included: dizziness, headache, nausea, abdominal pain, uterine pain, delay of menstruation, heavy menstruation, uterine bleeding, or fatigue; common effects (reported by 1% to 10%) included diarrhea, vomiting, or painful menstruation; these effects usually disappeared within 48 hours.
Levonorgestrel Levonorgestrel is an estrane steroid derived from testosterone and is also known as 17α-ethynyl-18-methyl-19-nortestosterone or as 17α-ethynyl-18-methylestr-4-en-17β-ol-3-one. Levonorgestrel (levo=left) is one form of a steroid, norgestrel, that exists in two mirror image left and right forms (see Chirality (chemistry)). It is the hormonally active levorotatory enantiomer of the racemic mixture. It is a gonane progestin derived from 19-nortestosterone.
Levonorgestrel There are many brand names for levonorgestrel-only ECPs, including: Nogestat, AfterPill, Escapelle, Plan B, Levonelle, Glanique, NorLevo, Postinor-2, i-pill, Next Choice, 72-HOURS.
