1. What is Levonorgestrel powder?
Levonorgestrel powder is a a progestin that is used as contraception, sold under the brand name Plan B among others. It is useful within 120 hours as emergency birth control after unprotected sex or after failure of another birth control method(such as condom breakage, or missing 2 or more birth control pills). It works by preventing a woman’s egg from fully developing. It may also prevent the attachment of the woman’s egg to the wall of the uterus. but it will not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases. Levonorgestrel CAS: 797-63-7 is marketed mostly as a combination oral contraceptive under several brand names such as Alesse, Triphasil, and Min-Ovral.

Levonorgestrel CAS: 797-63-7 gives the users many non-contraceptive benefits: the amount of menstrual bleeding and the number of days of menstrual bleeding are reduced, which makes it suitable for the treatment of menorrhagia (heavy menstrual blood loss).
Dysmenorrhoea (painful menstruation) and premenstrual symptoms are also relieved. In addition, Levonorgestrel provides protection for the endometrium during hormone replacement therapy. The local release of levonorgestrel into the uterine cavity results in a strong uniform suppression of the endometrial epithelium as the epithelium becomes insensitive to estradiol released from the ovaries. This accounts for the reduction in menstrual blood loss. All possible patterns of bleeding are seen among users of Levonorgestrel; however, most of the women who experience total amenorrhoea continue to ovulate. The first months of use are often characterised by irregular, scanty bleeding, which in most cases resolves spontaneously. The menstrual pattern and fertility return to normal soon after Levonorgestrel is removed. The contraceptive efficacy is high with 5-year failure rates of 0.5-1.1 per 100 users. The absolute number of ectopic pregnancies is low, as is the rate per 1000 users. Levonorgestrel is equally effective in all age groups and the bodyweight of the user is not associated with failure of the method. In Western cultures continuance rates among users of Levonorgestrel CAS: 797-63-7 are comparable with those of other long-term methods of contraception. Premature removal of the device is most often associated with heavy menstrual bleeding and pain, as with other long-term methods of contraception, and is most common in the youngest age group. When adequately counselled about the benign nature of oligo- or amenorrhoea, most women are very willing to accept life without menstruation. The risk of premature removal can be markedly diminished with good pre-insertion counselling, which also markedly increases user satisfaction. User satisfaction is strongly associated with the information given at the time of Levonorgestrel insertion. Thus, the benefits of the levonorgestrel make it a very suitable method of contraception for most women.
