A new bill on dietary supplements recently passed by Congress will focus on adverse reactions that consumers suffer from supplements and various over-the-counter drugs, and should help identify those products that are most dangerous. The measure, S. 3546, would require that makers of dietary supplements and over-the-counter drugs inform the U.S. Food and Drug Administration (FDA) when they learn of "serious adverse events" linked to their products. The bill defines serious events as death, life-threatening experience, inpatient hospitalization, disability, birth defect, or medical/surgical intervention.
