If medication errors, such as a wrong prescription or administration, have caused you harm, you may be entitled to compensation in NSW.
A visit to the hospital or clinic is meant to help you feel better, not worse. But every year, thousands of Australians are harmed because a healthcare professional prescribed the wrong medication, a pharmacy dispensed the wrong medicine, or a critical interaction was missed. These medication errors are more common than many people realise, yet many are preventable. And when they cause injury, NSW law gives patients clear rights to seek compensation.
What Are Medication Errors?
Medication errors occur when a patient receives the wrong medicine prescribed, the wrong dose, or incorrect instructions, resulting in harm or a risk of harm. They can happen at any stage of care—during prescribing, dispensing, or administration.
Common scenarios include:
- A doctor or nurse practitioner prescribing medication that is not appropriate for your condition
- Errors in writing or transcribing a prescription
- Confusing medicines with similar names, leading to the wrong drug being prescribed
- A dosage that was too high or too low
- Failure to check allergies or existing medications
- A pharmacy dispensing the wrong drug or strength
In many cases, medication errors are preventable.
Medication Errors in Australia and beyond: How Big Is the Problem?
Studies show that roughly 250,000 hospitalisations in Australia are caused by medication-related errors and cost the health system about $1.4 billion every year. Sadly, 2/3 of these are preventable (Lim et al., 2020).
More specifically, an estimated 124,000 medication dispensing errors occur every year, or around 340 mistakes every day (Poole et al., 2021).
Research by the University of Manchester indicates that globally, about 1 in 20 patients experiences preventable medication-related harm (Panagioti et al, 2024). Additionally, dispensing errors happen at a rate of 1.6% across hospitals, communities, and pharmacies, highlighting that mistakes can occur at multiple points in the healthcare system (Um et al., 2024).
Common Medication Errors Examples
Medication mistakes are not abstract concepts—they cause real damage to real people. Some common medication errors examples seen include:
Wrong Medicine Prescribed
A patient is diagnosed incorrectly and given a drug that is inappropriate or contraindicated for their actual condition. In some cases, doctors prescribe medications with similar names, leading to serious adverse reactions.
Incorrect Dosage
Even the correct medication can become dangerous if prescribed at the wrong strength. Overdosing can cause toxicity, internal bleeding, organ damage, or neurological injury. Underdosing may allow a condition to worsen or become life-threatening.
Dangerous Drug Interactions
Many patients—particularly older Australians—take multiple medications. When a doctor prescribed the wrong medication without checking interactions, the combination can amplify side effects or cancel out essential treatments.
Ignoring Known Allergies
Prescribing a drug that a patient is known to be allergic to is a serious breach of care. Reactions can range from skin rashes to anaphylaxis requiring emergency treatment.
Pharmacy Dispensing Errors
Sometimes the prescription is correct, but the pharmacy supplies the wrong medicine or wrong dose. These errors can occur due to labelling mistakes, workload pressures, or poor checking systems.
The Real Impact on Patients and Families
When the wrong medication is given, the consequences often extend far beyond physical symptoms.
Patients may face:
- Extended hospitalisation or readmission
- Permanent organ damage or disability
- Chronic pain or ongoing medical complications
- Psychological distress, anxiety, and loss of trust in healthcare
- Loss of income and financial stress
- Reduced quality of life for themselves and their families
Medical negligence claims frequently involve patients who did nothing wrong—yet were left dealing with the fallout of a preventable medical mistake.
What to Do If You Receive the Wrong Medication
If you suspect you have been harmed by a medication error, acting quickly is critical.
- Prioritise Your Health
If you experience unexpected or severe symptoms, seek urgent medical attention. Do not continue taking the medication unless advised by a medical professional.
- Preserve Evidence
Keep the medication, packaging, prescription labels, and receipts. These items can later prove exactly what was prescribed and dispensed.
- Document Everything
Write down:
- The name and dosage of the medication
- When you started taking it
- Your symptoms and side effects
- When you realised something was wrong
Photographs of labels and visible injuries can be very helpful.
- Get a Second Medical Opinion
An independent doctor can assess the harm caused and help correct the error. Their records may later support a negligence claim.
- Report the Incident
You can report serious medication errors to:
- The treating doctor or medical practice
- The dispensing pharmacy
- Service NSW
- AHPRA, if professional conduct is in question
Medication Errors and Medical Negligence in NSW
Not every mistake with medication automatically gives you the right to compensation. In NSW, you can only make a claim if the error amounts to medical negligence.
To prove medical negligence, four key elements must be established:
- Duty of care: The doctor, pharmacist, or healthcare provider owed you a duty to act carefully.
- Breach of that duty: They failed to provide the standard of care expected from a reasonable health professional.
- Harm: You suffered actual injury, loss, or damage as a result of the mistake.
- Causation – Your injury was directly caused by the medication error.
When a doctor prescribes the wrong medication, courts consider whether a competent practitioner in the same situation would have acted differently. Again, not every error counts as negligence—there must be clear evidence that the care fell below professional standards.
Because these cases involve complex medical issues, expert medical evidence is usually required. Experienced Compensation Lawyers like ours can review your treatment, explain what should have been done, and confirm how the medication error caused your injury.
Who Can Be Held Liable?
Several people or entities may be responsible if a medication error causes harm:
- Doctors or specialists – for prescribing the wrong medication, dose, or failing to check for interactions or allergies.
- Pharmacists – for dispensing the wrong medicine, incorrect dosage, or failing to provide proper instructions.
- Hospitals or clinics – when systemic errors, poor procedures, or staff negligence contribute to the mistake.
- Nurses or other healthcare professionals – if they administer medication incorrectly or fail to follow proper protocols.
- Medical institutions or health services – if organisational failures, such as poor record-keeping or insufficient training, lead to an error.
In some cases, more than one party may be jointly liable, and identifying the responsible person or entity is crucial for a successful claim.
Time Limits for Medication Error Claims in NSW
NSW law sets strict time limits for medical negligence claims. In most cases, you must start your claim within three years from the date you first knew, or reasonably should have known, that your injury was caused by negligence.
Some exceptions apply, including for:
- Children
- People with limited decision-making capacity
If you miss these deadlines, you could permanently lose your right to compensation, regardless of how serious your injury is.
What Compensation Can Cover
A successful claim for medication errors may include compensation for:
- Past and future medical expenses
- Hospital and rehabilitation costs
- Lost income and reduced earning capacity
- Ongoing care and assistance
- Pain and suffering
- Loss of enjoyment of life
NSW law places limits on certain damages, and calculations can be complex. Early legal advice is essential.
How Much Compensation Might I Receive?
The amount of compensation depends on the seriousness of your injury and its impact on your life. Our experienced Sydney Medical Negligence Lawyers can help assess your case and provide a realistic estimate.
Accountability Improves Patient Safety
Holding healthcare providers accountable isn’t just about compensation. It helps make the system safer for everyone. Your actions can lead to better prescribing practices, stronger pharmacy checks, improved staff training, and a culture where mistakes are caught before others are hurt.
By speaking up after receiving the wrong medication, you’re not only protecting yourself—you may also prevent someone else from going through the same experience.
