Progesterone is a female hormone important for ovulation and menstruation. Progesterone causes changes in the lining of your uterus, making it easier for a fertilized egg to attach to the uterus at the beginning of pregnancy. Progesterone then helps your body maintain the pregnancy.

FIRST-Progesterone VGS 200 (for use in the vagina) is used to cause menstrual periods in women who have not yet reached menopause but are not having periods due to a lack of progesterone in the body.

FIRST-Progesterone VGS 200 is also used in fertility treatment as part of Assisted Reproductive Technology (ART) for women unable to get pregnant due to a lack of natural progesterone in the body.

FIRST-Progesterone VGS 200 is also used to prevent overgrowth in the lining of the uterus in postmenopausal women who are receiving estrogen hormone replacement therapy.

Desogestrel and ethinyl estradiol combination is used to prevent pregnancy. It is a birth control pill that contains two types of hormones, desogestrel and ethinyl estradiol, and when taken properly, prevents pregnancy. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.

No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective than birth control pills. Discuss your options for birth control with your doctor.

This medicine does not prevent HIV infection or other sexually transmitted diseases. It will not help as emergency contraception, such as after unprotected sexual contact.

This medicine is available only with your doctor's prescription.
