Ortho-Prefest is a combination of hormones (estrogen and progestin) used to treat symptoms of menopause (e.g., hot flashes, vaginal dryness) and to prevent bone loss (osteoporosis) in people at high risk. If you are only being treated for vaginal menopause symptoms, products applied locally such as vaginal creams, tablets, or rings should be considered before products taken by mouth or absorbed through the skin. There are several medications (e.g., raloxifene or bisphosphonates) that are safe and effective to prevent or treat bone loss. These medicines should be considered for use before estrogen/progestin HRT therapy for osteoporosis. If you have other medical conditions as well, and are prescribed estrogen/progestin HRT for more than one condition, consult your doctor about your treatment plan and its options.
