“Progestin” is a general term for a substance that causes some or all of the biologic effects of progesterone.
- Used in medicine to treat various health diseases and conditions.
- Topical progesterone products (preparations applied to the skin) marketed as cosmetics require no FDA approval prior to marketing. There is currently no limit on the amount of progesterone allowed in cosmetic products. In 1993 the FDA proposed a rule limiting progesterone-containing cosmetic products to a maximum level of 5 mg/oz with the product label instructing users not to exceed 2 oz per month. But this rule was never finalized.
- Women take progesterone by mouth for inducing menstrual periods; and treating abnormal uterine bleeding associated with hormonal imbalance, and severe symptoms of premenstrual syndrome (PMS). Progesterone is also used in combination with the hormone estrogen to “oppose estrogen” as part of hormone replacement therapy. If estrogen is given without progesterone, estrogen increases the risk of uterine cancer.
- Progesterone is also used to ease withdrawal symptoms when certain drugs (benzodiazepines) are discontinued.
- Progesterone cream is sometimes used in hormone replacement therapy and for treating menopausal symptoms such as hot flashes. Topical progesterone is also used for treating or preventing certain allergies in which hormones play a role; and for treating bloating, breast tenderness, decreased sex drive, depression, fatigue, lumpy (fibrocystic) breasts, headaches, low blood sugar, increased blood clotting, infertility, irritability, memory loss, miscarriages, brittle bones (osteoporosis), bone loss in younger women, symptoms of PMS, thyroid problems, “foggy thinking,” uterine cancer, uterine fibroids, water retention, weight gain, and vaginal irritation (vulval lichen sclerosis).
- Progesterone gel is sometimes used inside the vagina to expand the cervix (cervical ripening), treat breast pain in women with noncancerous breast disease, and to prevent and treat abnormal thickening of the lining of the uterus (endometrial hyperplasia).
- The progesterone prescription products that have been approved by the Food and Drug Administration (FDA) are LIKELY SAFE for most people when used by mouth, applied to the skin, applied into vagina, or injected into the muscle with the advice and care of a healthcare professional. However, progesterone can cause many side effects including stomach upset, changes in appetite, weight gain, fluid retention and swelling (edema), fatigue, acne, drowsiness or insomnia, allergic skin rashes, hives, fever, headache, depression, breast discomfort or enlargement, premenstrual syndrome (PMS)-like symptoms, altered menstrual cycles, irregular bleeding, and other side effects.
