When a device is failing frequently due to improper use, revising the labeling is an appropriate action because it addresses potential user misunderstandings or misuse by providing clearer instructions and warnings. Effective labeling is crucial in informing users how to properly use the device, thereby reducing the occurrences of improper use that lead to failures.

Improvement of labeling can include enhanced instructions for use, illustrations, or specific warnings about potential misuse, which can help users understand the proper operation of the device. This approach is often considered a first step before more drastic measures such as redesigning the product or recalling it, as it directly targets the root cause of the problem—user misunderstanding—without unnecessarily burdening the healthcare system or interrupting the availability of the product.

Recalls and redesigns are more extreme responses that can be resource-intensive and may be unnecessary if the issue can be managed through improved communication via labeling. A Dear Doctor letter may also inform healthcare providers about potential issues, but does not provide direct guidance to users who operate the device.
