User Instructions and Safety Information in Medical Device Regulations (MDR)
The Medical Device Regulation (MDR) introduced by the European Union in 2017 has brought about significant changes in the way medical devices are designed, manufactured, and marketed. One of the key aspects of MDR is the requirement for user instructions and safety information to be included with each device. This article will delve into the details of user instructions and safety information in MDR, including the format and content requirements.
