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.

ELESTRIN was studied in a placebo-controlled trial that included a total of 484 postmenopausal women. The adverse reactions that occurred at a rate greater than 5 percent in any of the treatment groups are summarized in Table 1.
