Prempro Information

Prempro, manufactured by Wyeth-Ayerst Laboratories, was approved by the U.S. Food and Drug Administration in November 1995. It is used to relieve hot flashes, other symptoms of menopause and osteoporosis. It is a combination of two hormones, an estrogen and a progestin, and is used only by menopausal women who have not undergone hysterectomy.

Prempro was the first estrogen/progestin combination available for hormone replacement therapy (HRT), and is still one of the most common HRT's prescribed by physicians today. In 2003, it was estimated that more than 10 million postmenopausal women in the U.S. take estrogen or estrogen-progestin products to treat the symptoms of menopause.

The FDA has required a black box warning on Prempro since 2003 that postmenopausal women who use Prempro have an increased risk of heart attack, stroke, invasive breast cancer, pulmonary embolism, and deep vein thrombosis. A study on HRT medication has shown such serious results for the participants that the study was cancelled to protect the health of the women participating in the study.

The International Journal of Cancer reported a study that found postmenopausal women who took HRT medication had an increased risk of breast cancer among all ethnicities. In July of 2005 the United Nations reclassified Prempro from "possible carcinogenic" to "carcinogenic".

An older study by the National Institute of Health (NIH), found such a considerable increase in the risk of strokes, blood clots, heart attacks, and breast cancer in the study participants using Prempro that they cancelled the study 3 years before it was scheduled to end to protect the lives and health of the study participants.

If you are taking Prempro, you should consult your health care provider about the danger of side effects. If you have already been injured because you used Prempro, you may have the basis for a Prempro lawsuit. Contact us today to have experienced Prempro attorneys contact you about your case.
