Product Description

Product Description

Levonorgestrel (Lee-voh-nor-jest-rel) is a medicine which is used in emergency hormonal contraception. Levonorgestrel is a hormone which is similar to the hormoneprogesterone that is produced by the body. It is used as emergency contraception to prevent a pregnancy after unprotected sex or after failure of a contraceptive method. It is thought to work by preventing the release of eggs from the ovary and preventing the sperm from penetrating an egg. It may also change the lining of the uterus which makes it difficult for an egg to develop.

Levonorgestrel should be taken as soon as possible. It should be taken within 12 hours but no later than 72 hours after unprotected sex. It can be taken at any time of the menstrual cycle but not if your menstrual period is overdue.

Usage:

Oral contraception

At low doses, levonorgestrel is used in monophasic and triphasic formulations of combined oral contraceptive pills, with available monophasic doses ranging from 100-250 µg, and triphasic doses of 50 µg/75 µg/125 µg.
At very low daily dose of 30 µg, levonorgestrel is used in some progestogen only pill formulations. Preliminary evidence suggests that for women above 75 kilograms(165 pounds) the oral contraceptive may lose some of its effectiveness, and for women above 80 kilograms(176 pounds) the oral contraceptive may lose effectiveness entirely.
