It is used as an emergency contraceptive tablet to prevent unwanted pregnancy in case of unprotected sex or contraception failure. The emergency contraceptive pill should be taken within 24-72 hours of having unprotected sex. The pill should be taken orally. Also, the sooner you take the pill, the better it is because as time passes by, the pill becomes less effective. Most of these pills are advised to be taken within 72 hours.
This tablet contains levonorgestrel as an active ingredient. When the active compound gets into the bloodstream, it blocks the formation of hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones are responsible for the development and release of eggs from the ovaries (ovulation). Hence, depending upon your reproductive cycle, the emergency pill works by delaying the process of ovulation. However, in case the ovary has already released the egg, the tablet works by disrupting the fertilization of the egg with the sperm. In case the fertilization has already occurred, it prevents the pregnancy by hindering the implantation (attachment) process in the uterus.
However, what most women need to know is the fact that the morning-after pill is not a primary form of birth control and should only be used in the case of an emergency. Moreover, it should not be confused with pills used to induce abortion. It is usually safe if tablets.
