16 May 2017 - Sometimes a drug can be used exactly as FDA approved it, taken just the way a doctor prescribed it, and a patient can still experience adverse events. When it comes to drugs, not all risks are known – even after approval.
Sadly, however, harm from medications also may come from known risks that could have been prevented. The Institute of Medicine (now called the National Academy of Medicine) estimated that at least 1.5 million preventable adverse drug events occur within our health care system each year. It’s a complex system where safety issues can arise at any turn.
