SIDE EFFECTS

The following serious adverse reactions are discussed elsewhere in the labeling:

Clinical Trials Experience

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 clinical practice.

In a 12-week, randomized, placebo-controlled trial of Evamist in 454 women, 80 to 90 percent of women randomized to active drug received at least 70 days of therapy and 75 to 85 percent randomized to placebo received at least 70 days of therapy.

The adverse reactions that occurred in at least 5 percent of women in any treatment group are shown in Table 1.

Application site reactions were reported in 3 out of 226 (1.3%) women treated with Evamist.

DRUG INTERACTIONS

No drug interaction studies have been conducted for Evamist.

Metabolic Interactions

In vitro and in vivo studies have shown that estrogens are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen drug metabolism. Inducers of CYP3A4 such as St. John's wort (Hypericum perforatum) preparations, phenobarbital, carbamazepine, and rifampin may reduce plasma concentrations of estrogens, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile. Inhibitors of CYP3A4 such as erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir and grapefruit juice may increase plasma concentrations of estrogens and may result in side effects.
