Of the many drugs that have been developed to help combat menopausal symptoms PremPro is a one of the most widely prescribed treatments. PremPro is a Combined Hormone Replacement Therapy (CHRT) manufactured by Wyeth. Women who take PremPro need to be aware of the considerable risks and the side effects of taking the drug. In July 2002, the National Institute of Health (NIH) halted a $700 million, eight year publicly funded study of the benefits of HRT, by The Women's Health Initiative (WHI) three years earlier than planned because of the risks associated with these drugs. Unfortunately, the risks associated with the treatments exceeded the benefits of the drug. Specifically, the study found a higher incidence of serious injury for women who took PremPro compared to those who received a placebo. The main conclusions of the study included: * The estrogen plus progestin combination does not prevent heart disease. * Those consuming estrogen as well as progestin combinations also found that the serious side effects exceeded the beneficial side effects. The study found that long-term use of PremPro is dangerous because PremPro significantly increases the risk of the following: * Stroke by 41%. * Blood Clots by 113%. * Heart Attacks - Cardiovascular Disease by 22%. * Breast Cancer by 26%. The risks were so alarming that the NIH canceled the study in advance of the planned end date citing the risks to the study's participants. Additionally, the Women's Health Initiative Memory Study (WHIMS), a sub study of the WHI, recently concluded that women treated in the study with PremPro, conjugated estrogens 0.625mg combined with medroxyprogesterone acetate 2.5mg, have a greater risk of developing probable dementia than those on placebo. A recent study by Newcomer et al., which found that there was a nearly 210 percent risk of developing lobular breast cancer among patients taking a CHRT therapy, PremPro, compared to those not undergoing any type of hormonal therapy treatment. This risk may be as high as 430%. Another large study that was conducted in the United Kingdom also was stopped prematurely because the founders of the study considered it unlikely that the trial would provide evidence to influence clinical practice in the next 10 years. Per the request of the U.S. Food and Drug Administration (FDA) in early 2003, Wyeth developed a 'Dear Health Care Professional" letter. Within the letter were details of the new black box warning label of PremPro, which also included information on the estrogen and progesterone combination treatments were not satisfactory in treating heart disease. Additionally, the warning included information from the Women's Health Initiative/National Institute of Health study detailing the potential adverse side effects of taking PremPro, and advised health care providers to prescribe PremPro for the shortest duration consistent with treatment goals. As a series of new study results from the WHI becomes available, the FDA has encouraged manufacturers to update their labels for estrogen- and progestin-containing drug products for postmenopausal women to include new information from these studies. This information will allow individuals to understand the risks as they are identified. In March 2003, the FDA approved a new, lower dose of PremPro to help with these goals. Numerous class action lawsuits have been filed because of injuries caused as a result of taking PremPro.
