Confidence is an injectable hormonal contraceptive made from synthetic progestin, similar to the natural hormone progesterone that is made by a woman’s body. Confidence contains a sterile aqueous suspension of Medroxyprogesterone Acetate 150 mg/ml. After Confidence is given intramuscularly, the hormone is released slowly into the bloodstream. A Confidence injection must be taken every three months. Confidence can be used throughout breastfeeding. However, the first injection should not be given to a breastfeeding mother until at least six weeks after birth.
