Depo-Provera? the Shot, is one of the most reliable, reversible contraceptive methods available today. It is a prescription medication that requires an almost painless injection into the upper arm or buttocks by a doctor or other health care provider once every three months. Unlike the 'Pill', it does not need to be taken every day.

Depo-Provera contains a hormone similar to the body's own natural progesterone that stops the release of a mature egg.

Depo-Provera is 99.7% effective, and only needs to be taken four times a year. If administered at the appropriate time, Depo-Provera is effective immediately. With continued use of Depo-Provera, menstrual bleeding generally decreases, and many women (55%) no longer have monthly periods at all after the first year. When the injections are discontinued, normal periods and fertility return, and most women can expect to become pregnant within nine months of their last injection. Women who are breast-feeding, or are smokers over 35 years of age are not excluded from using Depo-Provera. Because Depo-Provera does not contain estrogen, there are no estrogen-related side-effects. In addition, Depo-Provera is not affected by antibiotics, and may relieve PMS, painful periods and endometriosis. Depo-Provera may also reduce the risk of Pelvic Inflammatory Disease (PID), cancer of the uterus, and cancer of the ovaries in women using this method.

The most common side-effects of this method are changes in the menstrual cycle and change in weight (some women may lose weight while others may gain weight). The majority of Depo-Provera users report having no period after two years. Depo-Provera may not be suitable for women who have two or more conditions that may lead to a weakening of the bones including slim build, lack of exercise and smoking, or for women with a history of depression. Doctors may not prescribe Depo-Provera to women who are pregnant or have unusual vaginal bleeding, cancer of the breast, liver disease or blood clotting problems. Depo-Provera does not protect against sexually-transmitted diseases.

Depo-Provera costs about $50 CDN per shot.
