Wyeth has settled lawsuits with two women who developed breast cancers. The drug maker of Premarin and Prempro is facing more than 5,000 lawsuits. Hormone replacement therapy is used to treat symptoms that accompany menopause. In 2002, a hormone replacement study conducted by the National Institutes of Health (NIH) determined that Prempro, Premarin and similar drugs increased the risk of stroke, heart attacks, blood clots and breast cancer. The researchers who composed the study suggested that many of the women who took these drugs should quit and seek alternatives.
He lawsuit that these two women have filed claimed Wyeth failed to adequately warn them about the drugs’ breast cancer risks. Wyeth has since settled with both women for an undisclosed amount. So far, Wyeth has lost four of seven cases over these drugs since they began going to trial in 2006.
