Approximately 1.5 billion prescriptions are filled each year. However, these medications cannot be effective unless they are used properly. In a 1990 study (Heyduck, 1991) by the National Council on Patient Information and Education, researchers found that about one third of all patients fail to take their prescribed medications. The researchers estimated that about 7% of all prescriptions are never even filled. Of those that are filled, 4% are never picked up, and of those that are picked up, about 20% are never taken.
