Provera is a contraception given to women for preventing pregnancy. The drug is also prescribed for reducing pain and other symptoms caused by endometriosis, metastatic uterine or kidney cancer in women.

A progesterone, Provera works by preventing ovulation. It also alters the uterine lining and brings changes in the cervical mucus. These changes make it hard for the sperm to strike the fertilized egg and also for the fertilized egg to cling on to the uterus wall.

Provera has to be injected into the muscle. The normal dosage is once per week or once every three months, depending on your usage. You should not self inject the drug unless you fully know how to take injections.
