See BOXED WARNINGS, WARNINGS and PRECAUTIONS.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.

In a 12-week clinical trial, 209 postmenopausal women with vasomotor symptoms were treated with Enjuvia. Adverse events that occurred in the study at a rate greater than or equal to 5% and greater than placebo, regardless of relationship to study drug, are summarized in Table 8.

In a second 12-week clinical trial, 310 women with symptoms of vulvar and vaginal atrophy were treated (154 women with Enjuvia 0.3 mg tablets and 156 women with placebo). The only adverse event that occurred at a rate of >5% was headache; seven patients (4.55%) with Enjuvia and twelve patients (7.69%) with placebo.
