Estrogen therapy for postmenopausal vasomotor symptoms (hot flashes) was ubiquitous until the Women's Health Initiative Trials demonstrated increased breast cancer and stroke among hormone users (1), however, at 10 years all cause mortality was similar between he treated and control groups.(2) Currently, the Endocrine Society guidelines recommend a risk based approach to treating vasomotor syndromes with estrogen in women younger than 60.(3)  Most experts recommend against using compounded bio-identical hormone therapy due to a availability of FDA approved medications and a lack of demonstrated efficacy of the compounded agents. However, recent data suggests that bio-identical hormones are both safe and effective in reducing hot flashes in postmenopausal women.  Bijuva (estradiol and progesterone) capsules, 1 mg/100 mg,  a bio-identical hormone therapy combination for the treatment of moderate to severe vasomotor symptoms due to menopause in women with a uterus was recently approved by the FDA. Approval was based on the Replenish Trial, a phase 3 study that demonstrated that both estradiol 1 mg/progesterone 100 mg and estradiol 0.5 mg/progesterone 100 mg significantly better than placebo at reducing the frequency and severity of hot flashes and reported no endometrial hyperplasia or malignancy.
