E-cigarette use or vaping: reporting suspected adverse reactions

The Medicines and Healthcare products Regulatory Agency (MHRA) is requesting that healthcare professionals report any suspected side effects or safety concerns with e-cigarettes and the e-liquids used for vaping to the Yellow Card Scheme.

Healthcare professionals are advised to have a high index of suspicion for lung injury in patients with respiratory symptoms who have a history of e-cigarette use in the past 30 days. Case definitions are provided in this letter to facilitate identification of probable or possible cases of e-cigarette or vaping association lung injury.

Information received from healthcare professionals about their suspicions regarding e-cigarette or vaping use as a possible cause of lung injury is important for evaluation of a potential public health risk.
