Uniservo Medex

It is used as an emergency contraceptive tablet to prevent unwanted pregnancy in case of unprotected sex or contraception failure. As the name suggests, it should be taken as soon as possible, preferably within 72 hours of unprotected sex.
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.
