An adverse reaction is a harmful and unintended effect of a medicine. This applies regardless of whether or not the medicine has been used as described in the product information.
The definition also includes harmful and unintended effects linked to:
- overdoses
- misuse (incorrect use)
- abuse
- medication errors
- dosing errors
- off-label use (treatment not covered by the approved indication for use)
- occupational exposure
