What is it?

The Yellow Card Scheme is run by the Medicines and Healthcare Products Regulatory Agency (MHRA). It collects, collates and investigates reports of suspected adverse drug reactions (ADRs).  The MHRA and its predecessor organisations have collected reports of suspected ADRS through the YCS since its introduction in 1964. Over 1 million yellow card reports have been collected since the scheme was established. It was the world’s first spontaneous reporting scheme for the reporting of suspected adverse drug reactions and is the cornerstone of post marketing drug safety surveillance in the UK. The scheme is voluntary and relies on the identification and reporting of adverse drug reactions by health professionals and patients.
