A pharmacy dispensing error claim in Ontario may arise when the wrong medication, dose or instructions cause harm. Seek medical care, preserve the label and packaging, request pharmacy records and record what happened. The outcome depends on the evidence and circumstances.
Key takeaways: Preserve the medication container, prescription, receipts, pharmacy communications and medical records; document symptoms and follow-up care.
Methadone and why accuracy matters
Methadone is used to treat opioid use disorder and, in some cases, pain. A prescriber sets an individualized dose based on the patient’s history and tolerance, often adjusting it gradually. The pharmacist’s role is to dispense exactly what was prescribed, to the right patient, and in many programmes to supervise the patient taking the dose.
Because methadone is potent and a safe dose varies from person to person, even a modest error can be dangerous. A dose that is safe for one patient may be harmful to another.
How dispensing errors happen
Examples of dispensing errors include:
• a decimal or measurement error, for example dispensing 100 mL instead of 10 mL;
• giving one patient another patient’s dose;
• dispensing the wrong medication or the wrong strength;
• incorrect labelling or instructions.
Factors that may contribute include high prescription volumes, understaffing, fatigue and disorganized dispensing processes. These factors do not excuse errors, but they can be relevant to understanding how an error occurred and whether systems were reasonable.
If you suspect an overdose
An opioid overdose is a medical emergency. Call 911. Naloxone can temporarily reverse the effects of an opioid overdose, and Health Canada provides information about how to obtain and use naloxone kits. Anyone who receives methadone, and their family members, may wish to have naloxone available.
Stigma and being believed
People who receive treatment for opioid use disorder may face stigma, and some worry that they will not be believed if they report an error. Evidence is therefore particularly important. A clear record of what was prescribed, what was dispensed and what happened afterwards can make a significant difference.
Evidence to preserve
• Keep the medication container, bottle or cup, and any label, even if empty.
• Take photos of the label and the medication.
• Write down when and where you received the dose, who dispensed it and what you noticed.
• Ask for copies of your prescription and dispensing records.
• Keep hospital and medical records documenting your symptoms and treatment.
• Note the names of any witnesses, including family members or staff.
A claim in negligence
A civil claim arising from a dispensing error is usually framed in negligence against the pharmacy and, in some cases, the individual pharmacist or other staff. In general terms, the injured person must show that the defendant owed a duty of care, that the standard of care was breached, and that the breach caused injury and losses. Expert evidence about pharmacy practice standards is often needed.
Damages may include compensation for the physical and psychological effects of the error, medical expenses, lost income and other losses, depending on the facts. Where a person dies as a result of an error, family members may have claims under Ontario law.
Complaints to the regulator
Pharmacists and pharmacies in Ontario are regulated by the Ontario College of Pharmacists. A complaint to the College is a separate process from a civil claim. The College’s process is concerned with professional conduct and public protection; it does not award compensation. The details of the complaints process should be confirmed on the College’s website.
Dispensing errors beyond methadone
Although this article focuses on methadone, dispensing errors can occur with any medication. Errors involving blood thinners, insulin, opioids, heart medications and medications for children can be particularly dangerous. Look-alike and sound-alike drug names, illegible prescriptions and similar packaging have been described as common sources of error. If you notice that a medication looks different from usual, has a different label or seems to have different instructions, ask the pharmacist before taking it.
Who may be responsible
Depending on how the error occurred, responsibility may rest with the pharmacy business, the pharmacist who dispensed or checked the medication, or other staff. In some cases, an error may originate with the prescription itself, which could involve the prescriber. Identifying where the error happened is an important part of assessing a claim, and pharmacy records, including dispensing logs and electronic records, may help show what occurred.
Time limits
Claims arising from a dispensing error are subject to limitation periods. Because the effects of an error are sometimes not understood immediately, it is advisable to get advice soon after an error is discovered.
