Description:

Levonorgestrel (or l-norgestrel or D-norgestrel) is a second generation progestin (synthetic progestogen) used as an active ingredient in some hormonal contraceptives, including combined oral contraceptive pills, progestogen only pills, emergency contraceptive pills, intrauterine systems, contraceptive implants, and hormone replacement therapy.
It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system



Application:

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 μ G, and triphasic doses of 50 μ G/75 μ G/125 μ G. At very low daily dose of 30 μ G, levonorgestrel is used in some progestogen only pill formulations.

Emergency contraception
Levonorgestrel is used in emergency contraceptive pills (ECPs), both in a combined Yuzpe regimen which includes estrogen, and as a levonorgestrel-only method. The levonorgestrel-only method uses levonorgestrel 1.5 mg (as a single dose or as two 0.75 mg doses 12 hours apart) taken within 3 days of unprotected sex, with one study indicating that beginning as late as 120 hours (5 days) after intercourse could be effective.

Intrauterine system
Levonorgestrel is the active ingredient in the Mirena & Skyla (Jaydess) intrauterine system.
