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 practice.

Adverse reactions reported by ≥5 percent of subjects in controlled clinical studies of femhrt are shown in Table 1.

Table 1: Associated Adverse Reactions Reported by ≥5 Percent of Subjects by Body System *
