Dom-Medroxyprogesterone

The recommended adult dose of medroxyprogesterone varies widely and depends on the condition being treated and the response to treatment.

For hormone replacement therapy, the dose ranges from 2.5 mg daily to 10 mg daily for several specific days of the month.

To control unusual and heavy bleeding of the uterus, or for treating unusual stopping of menstrual periods, a typical dose of medroxyprogesterone is 5 mg to 10 mg daily for 10 to 14 days per month.

A typical dose to treat breast cancer is 400 mg daily, and a typical dose **for endometrial cancer treatment **is 200 mg to 400 mg daily.

Medroxyprogesterone may be taken with or without food.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

**Unless medroxyprogesterone is being taken as part of breast cancer treatment, **this medication should not be taken by women without an intact uterus.

Important information about estrogen and progesterone:

• This medication should be used at the lowest dose that relieves your menopausal symptoms for the shortest time period possible.

• You should not use estrogens with or without progestins to prevent heart disease, heart attacks, or strokes.

Many of these warnings apply to medroxyprogesterone because it is often taken with estrogen. It is not clear whether they are as likely to occur if medroxyprogesterone is taken alone or with medications to treat cancer. People taking this medication to treat cancer should discuss the risks and benefits of progestins with their doctor.

If you have a history of clotting, you may be at increased risk of experiencing blood-clot-related problems such as heart attack, stroke, or clots in the deep veins of your leg.
