How common are medication errors?

Most people trust that the medication that they receive from the pharmacy or treatment nurse is just what the doctor ordered. Unfortunately, problems with the wrong medication or wrong dosage being dispensed cause numerous serious injuries and cost many lives each year. According to the Institute of Medicine, every year 1.5-million patients suffer from mistakes with the medicine they're given.

An Auburn University study projected the odds of being the victim of a prescription error that results in a serious, health-threatening issue is about 1 in 1,000, a rate that could amount to 3.7 million such errors a per year.
