Duavee (conjugated estrogens/bazedoxifene) is a prescription drug that’s used to manage certain symptoms of menopause. The drug comes as a tablet you swallow. It’s usually taken once per day.
Duavee is prescribed for females* who have a uterus to:
- help prevent osteoporosis after menopause
- treat moderate to severe vasomotor symptoms of menopause, including hot flashes, flushing, and night sweats
Duavee contains two active ingredients: conjugated estrogens (a mixture of several types of estrogen) and bazedoxifene. (An active ingredient is what makes a drug work.) Conjugated estrogens are a type of hormone replacement therapy, and bazedoxifene belongs to a group of drugs called selective estrogen receptor modulators (SERMs).
