What is Duavive?
Duavive is a combination medication that includes both conjugated estrogens and bazedoxifene acetate.
Duavive is indicated for use as a treatment for severe vasomotor symptoms that are associated with menopause, in women that still have an intact uterus.
It’s important to remember that Duavive shouldn’t be taken with a progestin, additional estrogens, or selective estrogen receptor modulators (SERMs).
For more resources, including a full list of the risks and benefits of Duavive, please review the product monograph.
How does Duavive work?
As women enter the menopausal transition, and move into menopause/postmenopause, their bodies begin producing less natural estrogen.
Duavive replaces some of those missing hormones. In turn, this helps relieve vasomotor symptoms that are associated with reduced estrogen levels.
Duavive also contains bazedoxifene, a selective estrogen receptor modulator, which also helps reduce the risk of endometrial hyperplasia (an overgrowth of the lining of the uterus).
It’s important to note that Duavive is only indicated for use by women with an intact uterus.
What is Duavive used to treat?
Duavive is used to treat women with an intact womb (uterus), who are experiencing moderate to severe vasomotor symptoms associated with menopause.
It’s very important to note that Duavive shouldn’t be used by people who have had their uterus removed.
Also, Duavive shouldn’t be taken with progestin, additional estrogen, or any additional selective estrogen receptor modulators (i.e., raloxifene).
How do you take Duavive?
Duavive tablets are to be taken once daily, orally. Pills can be taken with or without food, and should be swallowed whole. Never chew, break, or dissolve Duavive tablets for use.
Although it doesn’t matter what time of day you take your Duavive dosage, it’s a good idea to take it at the same time each day.
This will help the hormone levels remain as stable as possible in your system.

MHT is the most effective treatment for menopausal symptoms and has been shown to prevent bone loss.
In menopausal women who start appropriately-dosed MHT prior to age 60 OR within 10 years of their last period, the health benefits outweigh the risks.
Risks of MHT are considered very rare (~1 case per 1000 to 10,000 women on MHT per year) and may include:
- risks of stroke or blood clots in legs or lungs with oral estrogen (much lower risk with estrogen gel or patch)
- risks of dementia in women older than 65 years,
- risk of breast cancer (less than ~1 case per 1000 women on MHT per year)
These conditions are all rare, but they highlight the importance of having a full discussion with your healthcare practitioner; especially if you’re experiencing moderate to severe side effects.
Individualization is key, and your MHT treatment plan should be reassessed (at least) once a year to monitor your health, as well as ensure that you are on the correct dosage and formulation.
Your practitioner can help you find balance between treating your symptoms safely, and avoiding increased risks.
