Levonorgestrel – ethinyl estradiol is a progestin (levonorgestrel) and estrogen (ethinyl estradiol) combination birth control pill used for the prevention of pregnancy. The ingredients of the medication work by preventing ovulation (the release of an egg from an ovary) and causing changes in the mucus of the cervix which make it difficult for sperm to penetrate and for an egg to implant. This medication may also be taken to treat acne in women 14 years of age and older or to regulate the menstrual cycle.

Alesse is also effective as an emergency contraceptive.

MIRCETTE® (desogestrel/ethinyl estradiol and ethinyl estradiol) Tablets has excellent cycle control as demonstrated by clinical trials. The regimen begins with 21 days of 20 mcg ethinyl estradiol and 150 mcg desogestrel. The last seven days in the cycle start with two days of placebo pills, followed by five days of 10 mcg ethinyl estradiol pills.

Traditionally, oral contraceptives (OCs) have had very similar progestins. Even recently developed progestins have all had structures resembling androgens — until now.

YASMIN is the only OC with the novel, dual-property progestin, drospirenone — the only progestin that has AntiMineralocorticoid and AntiAndrogenic* properties. Drospirenone represents a unique class of progestins with an entirely different molecular structure and activity profile than the currently available progestins. Drospirenone is an analogue of spironolactone.

Triphasil is used to prevent pregnancy or to regulate your menstrual cycle. Certain brands of birth control pills may be used for treating acne or as a “morning after” pill for emergency contraception. Consult your doctor or pharmacist. Use of Triphasil does not protect you or your partner against sexually transmitted diseases (e.g., HIV, gonorrhea).
