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.

|Body System / Signs and Symptoms||Number (%) of Subjects|
(n = 137)
|ELESTRIN 0.87 g/day
(n = 136)
|ELESTRIN 1.7 g/day
(n = 142)
|Reproductive system & breast disorders|
|Breast tenderness||5 (3.6)||9 (6.6)||11 (7.7)|
|Metrorrhagia||3 (2.2)||6 (4.4)||13 (9.2)|
|Respiratory, thoracic & mediastinal disorders|
|Nasopharyngitis||10 (7.3)||14 (10.3)||12 (8.5)|
|Upper respiratory tract infection||5 (3.6)||8 (5.9)||5 (3.5)|
