Duavee: Uses, indications and precautions when using

This is an automatically translated article.


Duavee is a prescription medication that contains a mixture of estrogen and bazedoxifene. Duavee is effective in improving moderate to severe hot flashes during menopause in women entering middle age. Since the ovaries normally stop producing estrogen in women between the ages of 45 and 55, the drop in estrogen levels in the body causes unpleasant symptoms during menopause. Accordingly, actively supplementing with estrogen can help women feel more comfortable during this period.

1. What is the effect of Duavee?


Duavee is a combination of two ingredients including estrogen and bazedoxifene. Duavee is indicated in women for the treatment of moderate to severe hot flashes associated with perimenopause and menopause. At the same time, Duavee is also used for the prevention of postmenopausal osteoporosis.
When prescribing Duavee for the prevention of postmenopausal osteoporosis, this therapy should only be considered for women at significant risk of osteoporosis and consideration should be given to initiating non-estrogen therapy first.
Because of the exogenous hormone component, Duavee should be used for the shortest period of time consistent with treatment goals and individual risk considerations for each woman. Postmenopausal women should be periodically evaluated clinically to determine whether continued treatment with Duavee is necessary.

2. How to use Duavee?


Duavee is presented as a pink, oval, biconvex, tablet with an estroge n/bazedoxifene content of 0.45 mg/20 mg. The drug is taken orally, once daily, regardless of meals. The tablet should be swallowed whole, without chewing, crushing or breaking the structure of the tablet.
The recommended dosage in all cases is one Duavee pill per day. For indications of Duavee for the prevention of postmenopausal osteoporosis, a woman should be advised to include vitamin D and calcium in her diet or as a supplement if daily intake is inadequate. If a dose of Duavee is missed, the patient should take it as soon as he or she remembers unless it is almost time for the next dose. However, do not arbitrarily double the dose.

4.7 Hypertriglyceridemia In women with pre-existing hypertriglyceridemia, estrogen therapy may increase plasma triglycerides leading to acute pancreatitis. At this time, patients need to stop taking Duavee if they have pancreatitis.
4.8 Hypothyroidism Use of estrogen leads to increased levels of thyroid-binding globulin. Women with normal thyroid function can compensate for increased globulin levels by producing more thyroid hormone, thereby maintaining serum levels of free T4 and free T3 in the normal range. In contrast, women who are dependent on thyroid hormone replacement therapy may need an increased dose of thyroid replacement therapy if estrogen supplementation is available. At the same time, thyroid function monitoring tests should be performed periodically to maintain the level of free thyroid hormone within the therapeutic range.
