Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about Duavive. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking DUAVIVE against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.
What DUAVIVE is used for
This medicine is used for the treatment of symptoms, such as “hot flushes” and sweating, which are associated with menopause in women who still have their uterus (womb).
How Duavive works
This medicine contains two active substances called conjugated estrogens and bazedoxifene. Conjugated estrogens belong to a group of medicines called menopausal hormone therapy (MHT). Bazedoxifene belongs to a group of non-hormonal medicines called selective estrogen receptor modulators (SERMs).
Menopause occurs naturally in women, typically between the ages of 45 and 55. During menopause, your body produces less estrogen than it did beforehand. This can cause symptoms such as “hot flushes”.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is not addictive.
This medicine is available only with a doctor’s prescription.
