    Progestogens, Steroid hormone




    Levonorgestrel (or l-norgestrel or D-norgestrel) (Plan B, Next Choice, Postinor, "the morning after pill," and others) is a second generation 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.






    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.
