In their lawsuit filed in Washoe County District Court, three Northern Nevada women contend Wyeth minimized the risk involved with Prempro and Premarin, and failed to adequately test the drugs.
75-year-old Jeraldine Scofield of Fallon, 67-year-old Arlene Rowatt of Incline Village and 65-year-old Pamela Forrester of Yerington were diagnosed with breast cancer after taking the drugs to alleviate the symptoms of menopause.
The trial, which is expected to last six weeks, will begin tomorrow with jury selection and Tuesday with opening statements.
Both drugs remain on the market and carry the approval of the U-S Food and Drug Administration, and both continue to be prescribed annually to hundreds of thousands of women.
Delaware-based Wyeth contends the three Nevada women knew or should have known about the risk of taking Prempro and there's no connection between breast cancer and the drugs.
