The Institute of Medicine estimates that at least 1.5 million preventable injuries and deaths result each year from overdosing, mix-ups and unintended exposure to prescription drugs. Children are often the victims — one study found that, between 2003 and 2006, more than 9,000 children were accidentally exposed to prescription drugs such as codeine and morphine.
