What is Duavee?
Duavee is a prescription medicine that contains a mixture of estrogens and bazedoxifene.
What is Duavee used for?
Duavee is used after menopause for women with a uterus to:
- reduce moderate to severe hot flushes Estrogens are hormones made by a woman's ovaries. The ovaries normally stop making estrogens when a woman is between 45 and 55 years old. This drop in body estrogen levels causes the “change of life” or menopause (the end of monthly menstrual periods). Sometimes both ovaries are removed during an operation before natural menopause takes place. The sudden drop in estrogen levels causes “surgical menopause.”
When the estrogen levels begin dropping, some women get very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden intense episodes of heat and sweating (“hot flashes” or “hot flushes”). In some women, the symptoms are mild, and they will not need to take medicines. In other women, symptoms can be more severe.
- help reduce your chances of developing osteoporosis (thin, weak bones) If you use Duavee only to prevent osteoporosis due to menopause, talk with your healthcare provider about whether a different treatment or medicine without estrogens might be better for you.
Duavee should be taken for the shortest time possible and only for as long as treatment is needed.
You and your healthcare provider should talk regularly about whether you still need treatment with Duavee.
Duavee is not for use in children.
It is not known if Duavee is safe and effective in people with kidney problems.

- have unusual vaginal bleeding. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause.
- currently have or have had certain cancers. Estrogens may increase the chances of getting certain types of cancers, including cancer of the breast or uterus. If you have or have had cancer, talk with your healthcare provider about whether you should use Duavee.
- currently have or have had liver problems
- have been diagnosed with a bleeding disorder
- think you may be pregnant. Duavee is not for pregnant women. If you think you may be pregnant, you should have a pregnancy test and know the results. Do not take Duavee if the test is positive and talk to your healthcare provider.
