Especially shocked the scientific community that the risk persists for 2 years after discontinuation of the drug.

What to do for the patient?

In a sense, the news about the side effects of statins can discipline the potential group of patients that break all the doctors ‘ orders and secretly hope for the miraculous power of tablets, which they must prescribe.
