What is FIRST-Progesterone VGS 200?

Progesterone is a female hormone that plays a key role in ovulation and menstruation. It causes changes in the lining of the uterus, making it easier for a fertilized egg to attach to the uterus at the start of pregnancy. Progesterone also helps your body keep the pregnancy going.

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

FIRST-Progesterone VGS 200 is also used in fertility treatments as part of Assisted Reproductive Technology (ART) for women who cannot get pregnant because of a lack of natural progesterone in the body.

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

FIRST-Progesterone VGS 200 may also be used for reasons not listed in this medication guide.
