Medical Device Alert

Medical Device Alert

A public notice introduced by the UK Medicines and Healthcare products Regulatory Agency (MHRA) in 2003, to replace the previous array of safety warnings (Hazard notice, Safety notice, Device alert, Advice notice and Pacemaker technical note). MDAs are distributed to the NHS in England via the Department of Health's Central Alerting System, and are the MHRA’s primary means of communicating safety information to medical device users in health and social care. MDAs remain valid unless they are updated or withdrawn. They are reviewed once they are five years old (and every subsequent year).
