Patient Education

Estrogen and Progestin (Hormone Replacement Therapy)


Combinations of estrogen and progestin are used to treat certain symptoms of menopause. Estrogen and progestin are two female sex hormones. Hormone replacement therapy works by replacing estrogen hormone that is no longer being made by the body. Estrogen reduces feelings of warmth in the upper body and periods of sweating and heat (hot flashes), vaginal symptoms (itching, burning, and dryness) and difficulty with urination, but it does not relieve other symptoms of menopause such as nervousness or depression. Estrogen also prevents thinning of the bones (osteoporosis) in menopausal women. Progestin is added to estrogen in hormone replacement therapy to reduce the risk of uterine cancer in women who still have their uterus.

Medroxyprogesterone


Medroxyprogesterone is used to treat abnormal menstruation (periods) or irregular vaginal bleeding. Medroxyprogesterone is also used to bring on a normal menstrual cycle in women who menstruated normally in the past but have not menstruated for at least 6 months and who are not pregnant or undergoing menopause (change of life). Medroxyprogesterone is also used to prevent overgrowth of the lining of the uterus (womb) and may decrease the risk of cancer of the uterus in patients who are taking estrogen. Medroxyprogesterone is in a class of medications called progestins. It works by stopping the growth of the lining of the uterus and by causing the uterus to produce certain hormones.

Medroxyprogesterone Injection


Medroxyprogesterone intramuscular (into a muscle) injection and medroxyprogesterone subcutaneous (under the skin) injection are used to prevent pregnancy. Medroxyprogesterone subcutaneous injection is also used to treat endometriosis (a condition in which the type of tissue that lines the uterus (womb) grows in other areas of the body and causes pain, heavy or irregular menstruation [periods], and other symptoms). Medroxyprogesterone is in a class of medications called progestins. It works to prevent pregnancy by preventing ovulation (the release of eggs from the ovaries). Medroxyprogesterone also thins the lining of the uterus. This helps to prevent pregnancy in all women and slows the spread of tissue from the uterus to other parts of the body in women who have endometriosis. Medroxyprogesterone injection is a very effective method of birth control but does not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) or other sexually transmitted diseases.
