Reporting suspected adverse drug reactions

The Yellow Card Scheme is run by the Medicines and Healthcare products Regulatory Agency (MHRA). The Scheme is used to collect information from Healthcare Professionals and patients on suspected Adverse Drug Reactions (ADRs). It is vital in helping the MHRA monitor the safety of the medicines and vaccines that are on the market.


Both Healthcare Professionals and patients can submit information through the Yellow Card website.


Further information is available on the Yellow Card website.
