In a New York Times Op-Ed piece on Monday, Eric Topol comments on last week’s announcement by the FDA that it was changing the label for statins. Topol focuses on the new warning that statins raise the risk of diabetes. He opens with a provocative statement: We’re overdosing on cholesterol-lowering statins, and the consequence could be a sharp increase in the incidence of Type 2 diabetes. Topol does the math and calculates that 20 million Americans taking statins equates to 100,000 new statin-induced diabetics: Not a good thing for the public health and certainly not good for the individual affected with a new serious chronic illness… If there were a major suppression of heart attacks or strokes or deaths, that might be justified. But in patients who have never had heart disease and are taking statins to lower their risk (so-called primary prevention), the reduction of heart attacks and other major events is only 2 per 100. And we don’t know who the 2 per 100 patients are who benefit or the one per 200 who will get diabetes! Moreover, the margin of benefit to risk is quite narrow.
