Medroxyprogesterone injection

Generic name: Medroxyprogesterone (injection)

Usage of Medroxyprogesterone injection

Medroxyprogesterone is a form of progesterone, a female hormone that prevents ovulation (the release of an egg from an ovary). medroxyprogesterone also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Medroxyprogesterone is used as contraception to prevent pregnancy. It is also used to reduce pain caused by endometriosis.

Medroxyprogesterone may also be used for purposes not listed in this medication guide.

Before taking Medroxyprogesterone injection

You may need to have a negative pregnancy test before you start this medicine.

You should not use medroxyprogesterone if you are pregnant, or if you have:

abnormal vaginal bleeding that has not been checked by a doctor;

liver disease;

breast cancer; or

a history of stroke or blood clot.

Medroxyprogesterone can decrease the calcium stored in your bones, which may cause bone loss (osteoporosis) when the medicine is used over long periods of time. Bone loss may not be reversible.

You may be more likely to have a broken bone if your bones get weak from calcium loss, especially after menopause. You should not use this medicine for longer than 2 years unless other birth control methods are not right for you. Ask your doctor.

Tell your doctor if you have ever had:

light or irregular menstrual periods;

risk factors for osteoporosis (such as low bone mineral density, a family history of osteoporosis, drinking large amounts of alcohol, or if you smoke);

a breast lump, an abnormal mammogram, or bleeding from your nipples;

kidney disease;

high blood pressure;

breast cancer (in you or a family member);

diabetes;

depression, or an eating disorder;

seizures;

asthma; or

migraine headaches.

Tell your doctor right away if you become pregnant, or if you plan to become pregnant soon after you stop using medroxyprogesterone.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

How to use Medroxyprogesterone injection

Medroxyprogesterone is injected into a muscle or under the skin. A healthcare provider will give you this injection once every 3 months (12 to 14 weeks).

You may have breakthrough bleeding while using medroxyprogesterone. Tell your doctor if this bleeding continues or is very heavy.

medroxyprogesterone can affect the results of certain medical tests. Tell any doctor who treats you that you are using medroxyprogesterone.

Your doctor will need to see you on a regular basis while you are using medroxyprogesterone. If you use this medicine long-term, your bone density may need to be checked during treatment.
