Prempro, a hormone replacement therapy prescription medication, is a combination of estrogen and progestin. Its intended uses are to reduce symptoms of menopause and to reduce incidents of osteoporosis.
The National Heart, Lung and Blood Institute (NHLBI) conducted a federally funded study to determine the effectiveness of Prempro as a hormone replacement therapy. The study was halted prematurely when researchers determined the side effects of Prempro were so severe that they could no longer justify giving the pharmaceutical to patients. About 16,000 women received a letter advising them to stop taking Prempro, which is made from the urine of pregnant mares just like its sister drug, Premarin
Research indicated that when compared to a placebo, the Prempro estrogen-progestin combination resulted in the follow negative side effects: 26 percent increase in breast cancer; 41 percent increase in strokes; 29 percent increase in heart attacks; 113 percent increase blood clots; and
22 percent increase in cardiovascular disease
Class action lawsuits have been filed because of injuries as a result of Prempro. If you or a family member has taken Prempro and would like more information concerning your legal rights, you should contact an attorney.
