A new synthetic conjugated estrogen product (Cenestin - Duramed) was recently approved by the US Food and Drug Administration for treatment of vasomotor symptoms due to estrogen deficiency.

The FDA has approved Bijuva (TherapeuticsMD), a fixed-dose combination of estradiol and progesterone, for oral treatment of moderate to severe vasomotor symptoms (hot flashes) due to menopause in women with an intact uterus. The manufacturer is marketing Bijuva as "the first and only FDA-approved combination of bio-identical estradiol and bio-identical progesterone in a single daily oral capsule".

Estrogen is the most effective treatment for menopausal vasomotor symptoms (hot flashes), but the Women's Health Initiative study found that women who took estrogen plus a progestin for more than 5 years were at increased risk for myocardial infarction, stroke, pulmonary emboli, deep vein thrombosis, breast cancer, and possibly dementia. Are there effective alternatives?

Three low-dose transdermal estrogens were recently approved by the FDA for treatment of menopausal vasomotor symptoms. Elestrin and Divigel are transdermal estradiol gels and Evamist is an estradiol spray. Elestrin has been marketed in Europe since 1976.
