Medroxyprogesterone, a synthetic progestin hormone, is available in oral tablet and injectable forms and is commonly used to address various conditions related to the menstrual cycle, hormone balance, and contraception. This article provides a comprehensive overview of medroxyprogesterone, its uses, potential side effects with a focus on weight changes, and important considerations for individuals considering or currently taking this medication.
What is Medroxyprogesterone?
Medroxyprogesterone is a progestin hormone that is used to treat certain menstrual problems or prevent thickening of the uterine lining in postmenopausal women taking estrogen. The injection form is used to prevent pregnancy or relieve pain from endometriosis.
Common Uses of Medroxyprogesterone:
- Menstrual Irregularities: Management of missed periods (amenorrhea) or irregular bleeding.
- Hormone Replacement Therapy (HRT): Preventing thickening of the uterine lining in postmenopausal women taking estrogen.
- Contraception: Preventing pregnancy (injectable form).
- Endometriosis: Relieving pain caused by endometriosis (injectable form).
- Other Conditions: As determined by a healthcare provider, such as endometrial hyperplasia or endometrial cancer.
How Medroxyprogesterone Works
Medroxyprogesterone works by mimicking the effects of the natural hormone progesterone in the body. This helps to regulate the menstrual cycle, thin the uterine lining, and prevent the growth and release of eggs from the ovaries. Some medroxyprogesterone products prevent pregnancy by stopping the growth and release of an egg from your ovaries and by thickening the mucus in your cervix to block sperm from reaching the uterus.

- Oral Tablets: 2.5 mg, 5 mg, and 10 mg

Provera (Medroxyprogesterone): Regulating Menstrual Cycles
Provera is a progestin, a synthetic form of the hormone progesterone, which is naturally produced by the body after ovulation. Provera mimics progesterone, which helps regulate your menstrual cycle and thin your uterine lining. After taking Provera, your period will become more regular. Some people experience lighter periods than usual when taking this medication.
Provera is used to regulate periods and can also be used to delay periods. Healthcare providers typically prescribe the lowest effective dose and for the shortest amount of time possible.
Dosage and Administration
Your healthcare provider will instruct you to take Provera on certain days during your menstrual cycle. When used to treat amenorrhea (missing periods), Provera is taken for up to 10 days during the second half of the planned menstrual cycle. You should take Provera at the same time every day. Provera must be taken at certain times, so follow all instructions carefully.
