Have you ever been given the wrong dosage or the wrong medicine?
Medication can cause illness or injury under some conditions, according to the Institute of Medicine (IOM). For example, a very strong drug may carry a greater risk of harmful side effects.
But sometimes doctors, pharmacists or patients make errors — in prescribing a medication, in filling the prescription, or in taking the drug. These errors can be prevented. According to the IOM, approximately 1.5 million preventable adverse drug effects occur in the United States each year.
