Field safety notices: information from medical device manufacturers

List of field safety notices (FSNs) received by MHRA.



An FSN is a communication sent by medical device manufacturers, or their representatives, in connection with a field safety corrective action (FSCA).

If you receive an FSN from a manufacturer, always act on it.

You can see copies of field safety notices in our filecamp folder.

See the flyer on FSNs for more information on what they are and why it’s important to act on them. You can circulate this to customers.

Older FSNs are available on the National Archives website.
