Medroxyprogesterone (By injection)
Uses of This Medicine
Medroxyprogesterone injection is used to prevent pregnancy. It is a birth control method that works by stopping a woman’s egg from fully developing each month. The egg can no longer accept a sperm and fertilization is prevented.
No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective than birth control pills. Discuss your options for birth control with your doctor.
This medicine does not prevent AIDS or other sexually transmitted diseases. It will not help as emergency contraception, such as after unprotected sexual contact.
Medroxyprogesterone injection is also used with other medicines to help relieve symptoms of inoperable, recurrent, and metastatic (cancer that has already spread) endometrial or kidney cancer.
This medicine is to be administered only by or under the immediate supervision of your doctor.
