Which system is used to report adverse drug events?

• A. Vaccine Adverse Event Reporting System (VAERS)
• B. MedWatch
• C. Prescription Drug Monitoring Program (PDMP)
• D. Consumer Product Safety Commission (CPSC)

Answer: (B)

The MedWatch system is specifically designed for reporting adverse drug events. It is operated by the Food and Drug Administration (FDA) and allows healthcare professionals and the public to report any undesirable effects and product problems related to drugs and medical devices. This system plays a critical role in the post-marketing safety monitoring of medications, as it collects and analyzes reported adverse events to ensure patient safety and improve drug efficacy information.

Other systems mentioned in the options serve different purposes. For example, the Vaccine Adverse Event Reporting System (VAERS) focuses solely on vaccine-related adverse events, while the Prescription Drug Monitoring Program (PDMP) is used to track prescriptions of controlled substances to prevent misuse. The Consumer Product Safety Commission (CPSC) deals with product safety concerning consumer goods but does not directly address medication safety. Thus, MedWatch is the appropriate system for reporting adverse drug events, making it the correct choice.
