FDA limits use of testosterone drugs, warns of possible heart risk
(Reuters) - The U.S. Food and Drug Administration has asked makers of prescription testosterone therapies to change their labeling to clarify that their products are approved only for men with specific medical conditions and could increase the risk of heart attacks and strokes.
Prescriptions for low testosterone, or "Low T" have soared over the past decade, driven by a surge in use by men facing falling testosterone levels as they age.
The number of men being prescribed testosterone jumped more than 75 percent, to 2.3 million, between 2009 and 2013. About 70 percent of these patients were between the ages of 40 and 64, the FDA said.
Tuesday's ruling restricts companies from marketing or promoting their products for age-related low testosterone.
