How to Document a Medication Error
If you make or discover a medication error, the first job is the patient. The second is an honest, factual record. Both depend on knowing what goes where.
The short answer
Make sure the patient is safe, assess and monitor, notify the prescriber and your supervisor promptly, chart the facts of what was given and what you observed, and complete your employer's incident report separately. The College of Nurses of Ontario expects nurses to take action to prevent or minimize harm and to report errors, near misses and adverse reactions in a timely manner, and the Canadian Nurses Protective Society (CNPS) stresses prompt, honest reporting.
Step 1: Patient first
Assess the patient, take vital signs as appropriate, and get help. Report the error as soon as possible so that the patient can be treated. Follow your employer's process for urgent situations.
Step 2: Notify
Tell the prescriber and your manager or charge nurse promptly. Your employer's disclosure policy governs who talks to the patient or family and how; do not improvise a disclosure on your own.
Step 3: Chart the facts
- What was actually given: drug, dose, route, time, and the discrepancy from the order, described neutrally.
- Your assessment of the patient with measurements, and any monitoring plan.
- Who was notified, when, and what was ordered or advised.
- What the patient or family was told, by whom and when, if your policy has that in the clinical record.
- Your own entry only. Do not document medications that someone else administered.
Example (fictional patient)
0830: Patient L received 10 mg of a medication that was ordered at 5 mg PO. Discrepancy found at 0845 on second check of the order. Patient alert, BP 130/78, HR 76, RR 16, no complaints. Dr. notified at 0850; orders received for vitals every 30 minutes for 2 hours and a repeat assessment at 1100. Charge nurse informed at 0852. Patient told by Dr. at 0900 of the dose given and the plan.
Step 4: Keep the incident report separate
CNPS guidance advises documenting the event factually in the health record and completing the incident report through your employer's process, rather than writing "see incident report" in the chart. Incident reports serve risk management and trend tracking, so follow your employer's policy on what goes where.
What to avoid
- Blame or speculation ("pharmacy sent the wrong thing").
- Hiding or altering earlier entries. Use labelled late entries if you need to add information.
- Guessing at times or details you do not know.
- Delaying the report to avoid discussion.
Why honesty matters
CNPS notes that consequences can follow a medication error even when the patient is not harmed, which is why prompt, honest reporting and an accurate record matter. A factual, contemporaneous record is usually the strongest position for you and for the patient's ongoing care.

Where Fiabita fits
Fiabita's "Clean up my note" tool can help you reword rough notes into clearer, more objective language, and its SBAR handoff and incident-report tools ask guided questions so fewer details get lost under pressure. The output is a draft: you remain responsible for what goes into the record, and it does not check compliance with your regulator or employer. Do not enter information that could identify a real patient, and follow your workplace policy on which tools may be used.
FAQ
Q: Should I write "medication error" in the chart?
Practice varies. CNPS guidance recommends factual descriptions in the health record. Follow your employer's policy and describe what happened in neutral terms.
Q: What about near misses?
The CNO medication standard expects near misses to be reported too. Follow your employer's reporting process.
Q: Do students report errors?
Yes. Tell your instructor or preceptor immediately and follow your placement site's process.
