Understanding the claim
What can amount to medication errors?
A poor outcome alone does not prove negligence. The investigation considers what a reasonably competent healthcare professional should have done and whether any failure made a material difference to the outcome.
Wrong medication
This can justify investigation depending on the clinical circumstances, available evidence and harm caused.
Incorrect dose
This can justify investigation depending on the clinical circumstances, available evidence and harm caused.
Known allergy overlooked
This can justify investigation depending on the clinical circumstances, available evidence and harm caused.
Drug interaction not considered
This can justify investigation depending on the clinical circumstances, available evidence and harm caused.
Dispensing error
This can justify investigation depending on the clinical circumstances, available evidence and harm caused.
Failure to monitor medication safely
This can justify investigation depending on the clinical circumstances, available evidence and harm caused.

- Rehabilitation and treatment
- Equipment, travel or accommodation needs

Questions answered
Medication Errors FAQs
Can pharmacy errors be included?
Potentially. A dispensing error or failure to follow appropriate pharmacy processes can require investigation.
What if the wrong medication caused only short-term symptoms?
The seriousness of harm affects the viability and value of a claim. The circumstances still need to be assessed individually.
