An Introduction to Your Dosage of Provera
The dose of Provera®
acetate) your healthcare provider recommends will vary, depending on a number of factors, including:
- Why you are taking the medicine
- How you respond to it.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Provera Dosing for Amenorrhea
The standard dosage of Provera for treating amenorrhea (absence of menstrual periods) is 5 mg or 10 mg daily for 5 to 10 days. Menstrual-like vaginal bleeding normally occurs three to seven days after the medication is stopped.
Provera Dosing for Abnormal Vaginal Bleeding
The standard dose of Provera for abnormal vaginal bleeding is 5 mg or 10 mg daily for 5 to 10 days, starting on day 16 or 21 of the menstrual cycle. The first day of your period is considered day 1 of the menstrual cycle. Vaginal bleeding normally occurs three to seven days after Provera is stopped.
Provera Dosing for Preventing Endometrial Hyperplasia
The standard dosage of Provera for preventing endometrial hyperplasia (an overgrowth of the lining of the uterus) in postmenopausal women taking 0.625 mg of estrogen is Provera 5 mg
or 10 mg daily for 12 to 14 days (approximately half of a cycle), starting on day 1 or day 16 of the menstrual cycle.
When postmenopausal women take estrogen without a progestin, they have an increased risk for endometrial cancer (cancer of the lining of the uterus). Taking a progestin such as Provera in combination with an estrogen reduces the risk for endometrial cancer by preventing an overgrowth of the uterus. Women who no longer have a uterus (women who have had a hysterectomy) may take estrogen alone without a progestin.
It is typically recommended that women use the lowest effective dose of Provera. Women should be evaluated every three to six months to determine if treatment is still needed.
