You can try cleansing techniques to eliminate the synthetic hormone from where it is stored in your body's tissues. For example, drink lots of water every day, eat lots of fresh raw organic vegetables, drink raw vegetable juice, sweat in a steam room or sauna, do lots of exercise and get fresh air. You can also ask at a health food store about herbal formulas or teas that help detoxify your body or that balance female hormones, or talk with a naturopathic physician or herbalist. Weight gain, depression, breast tenderness, allergic reactions, and menstrual irregularities may continue until Depo Provera is cleared from a woman's body, which takes about 6 to 8 months after the last injection.
There is no scientific study proven to get Depo injection out of the system. Depo Provera is a birth control method given every three months. Women may be able to conceive from four to ten months after the last injection but it could take up to two years before fertility goes back to normal.
