FAQs
Common questions about medroxyprogesterone
Below you’ll find answers to a few commonly asked questions about medroxyprogesterone.
What brand names are available for medroxyprogesterone?
The brand-name version of medroxyprogesterone injection* is Depo-Provera. The brand-name version of medroxyprogesterone oral tablet is Provera.
Medroxyprogesterone is a generic medication. A generic medication is an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a medication work.) Generic drugs are considered to be just as safe and effective as brand-name drugs. And generic drugs typically cost less than brand-name drugs.
If you’re interested in a brand-name version of medroxyprogesterone, talk with your doctor.

How does medroxyprogesterone work? And how long does it take to start working?
Medroxyprogesterone is a synthetic (made in a lab) form of progesterone. This is one of the hormones involved in regulating your menstrual cycle. Medroxyprogesterone works by mimicking the effect of progesterone. How long it takes the drug to work depends on the reason you’re taking it.
For birth control:
- Medroxyprogesterone helps prevent pregnancy by stopping your ovaries from releasing an egg each month. The drug also thickens the mucus in your cervix, which makes it harder for sperm to enter your uterus (womb). And it thins the lining of your uterus, making it harder for an egg to implant (attach).
- If you receive medroxyprogesterone injection in the first 5 days of your menstrual cycle, the drug works to help prevent pregnancy right away. (Day 1 is the first day of your period.) If you have it at any other time in your cycle, the drug won’t help prevent pregnancy for 7 days.
For certain menstrual conditions:
- Medroxyprogesterone helps restore hormonal imbalances that cause your period to become irregular or stop altogether.
- You’ll take medroxyprogesterone oral tablet for 5–10 days each month as your doctor prescribes. This mimics the rise in progesterone that usually causes your period. Typically, you’ll get your period toward the end of taking the tablets. This helps make your periods regular.
For reducing the risk of endometrial cancer with estrogen hormone replacement therapy (HRT):
- Medroxyprogesterone works by opposing the effect of estrogen HRT. This type of HRT thickens the uterine lining, which increases your endometrial cancer risk. (Endometrial cancer is cancer of the lining of the uterus.)
- You’ll take medroxyprogesterone oral tablet for 12–14 days each month. This causes the lining to shed each month, similar to a period. You’ll typically experience monthly bleeding toward the end of taking the tablets. The shedding of the uterine lining helps reduce your risk of endometrial cancer.
If you have questions about how medroxyprogesterone works, talk with your doctor or pharmacist.
Uses
Uses of medroxyprogesterone
The Food and Drug Administration (FDA) approves prescription drugs such as medroxyprogesterone for certain conditions. Approved uses for medroxyprogesterone are described below. These uses differ based on the form of medroxyprogesterone prescribed.
Note: Sex and gender exist on spectrums. In this article, we use the term “female” to refer to a person’s sex assigned at birth.
Use for pregnancy prevention
Doctors may prescribe medroxyprogesterone injection for helping prevent pregnancy. It’s used for this purpose in females who’ve started menstruating. It’s usually prescribed as a long-term treatment.
Medroxyprogesterone is a long-acting form of birth control. Your doctor or another healthcare professional will inject the drug into your muscle every 3 months.
Doctors may not prescribe medroxyprogesterone injection for longer than 2 years unless other forms of birth control aren’t suitable. This is because long-term use may cause loss of bone mineral density.*
* Medroxyprogesterone injection has a boxed warning* for this side effect. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). To learn more about this, see the “Interactions and warnings for medroxyprogesterone” section.
Use for certain menstrual conditions
Doctors may prescribe medroxyprogesterone oral tablet for treating irregular periods or periods that have stopped. It’s used for this purpose in females who’ve started menstruating. It’s usually prescribed as a long-term treatment.
With irregular or no periods, you may have an imbalance of the hormones that regulate your menstrual cycle. Medroxyprogesterone oral tablet helps restore the imbalance so you have regular periods.
Doctors may not prescribe medroxyprogesterone oral tablet in certain situations. These include irregular periods caused by problems such as fibroids (unusual growths in or on the uterus).
Use as part of hormone replacement therapy to reduce endometrial cancer risk
Doctors may prescribe medroxyprogesterone oral tablet to reduce the risk of endometrial cancer* associated with estrogen hormone replacement therapy (HRT). It’s used for this purpose in certain females who’ve undergone menopause. It’s usually prescribed as a long-term treatment.
Estrogen HRT is prescribed to relieve symptoms of menopause. But in females with an intact uterus (womb), estrogen HRT causes the uterine lining to grow and build up. This can raise the risk of endometrial cancer.
Medroxyprogesterone treatment balances the effect of estrogen HRT. It makes the lining of your uterus shed, which helps lower your risk of endometrial cancer.
If you have questions about medroxyprogesterone treatment, talk with your doctor for more information.
* Endometrial cancer is cancer of the lining of the uterus.

Boxed warnings

To learn more about these warnings, read below. You can also talk with your doctor or pharmacist. Note that these risks depend on the form of the drug you’re taking.
Risk of loss of bone mineral density. Medroxyprogesterone injection* can cause a loss of bone mineral density that may weaken your bones. This may raise your risk of fractures. You may have more bone loss the longer you take medroxyprogesterone injection. Your bones may not recover fully after you stop taking the injection.
This side effect was commonly reported in studies of medroxyprogesterone injection. It’s not known whether it’s safe to take this medication while your bones are still growing. For instance, it may increase your risk of osteoporosis (thinning bones) and fractures later in life.
If you have concerns about low bone mineral density with medroxyprogesterone injection, talk with your doctor. They can help determine whether this form of birth control is right for you. They’ll likely recommend that you do not take the drug for longer than 2 years.
Your doctor may recommend taking calcium and vitamin D supplements while you’re receiving medroxyprogesterone injections. These supplements can help keep your bones strong.
Risk of breast cancer. Taking medroxyprogesterone oral tablet with estrogen for hormone replacement therapy (HRT) for menopause may increase your risk of breast cancer.
This side effect was rarely reported in studies of females† ages 50 years and older who took medroxyprogesterone with estrogen for HRT.
Symptoms of breast cancer can include a breast lump, pain in the breast, and nipple discharge (other than breast milk).
If you have concerns about this risk, talk with your doctor for more information. They can help you weigh the risks and benefits of HRT for menopausal symptoms.
Risk of heart and blood vessel problems. Taking medroxyprogesterone oral tablet with estrogen for HRT for menopause may increase your risk of certain heart and blood vessel problems. These include heart attack, stroke, and blood clots in your legs or lungs.
These side effects were rarely reported in studies of females† ages 50 years and older who took medroxyprogesterone with estrogen for HRT.

Risk of dementia. Taking medroxyprogesterone oral tablet with estrogen for HRT for menopause may raise your risk of dementia. Dementia was rarely reported in studies of females† ages 65 years and older who took medroxyprogesterone with estrogen for HRT. Different types of dementia were reported in these studies, including Alzheimer’s disease and vascular dementia.
With dementia, you have difficulty remembering, thinking, understanding, and communicating.
If you have concerns about the risk of dementia with HRT, tell your doctor. They can help you determine whether HRT is right for you.
