WASHINGTON (AP) — Federal health experts say there is little evidence that testosterone-boosting drugs are effective for treating common signs of aging and large studies are needed to support their continued use in millions of American men.
A panel of Food and Drug Administration advisers is recommending new prescribing language on blockbuster testosterone treatments to make clear they have not been proven to reverse common aging issues like low libido, fatigue and muscle loss. But even as experts recommended narrower use of the drugs, they acknowledged it will be difficult to change physician prescribing habits.
Testosterone drugs have grown into a multibillion dollar market driven by industry advertisements for new pills, patches, gels and injections that promise relief from "Low-T." Company promotions link low testosterone to a variety of ailments in older men.
