Can I make a wrong prescription claim?

You may be able to make a wrong prescription claim if a healthcare professional made a medication error that caused you avoidable harm. Prescription errors can range from being given the wrong drug entirely, to receiving an incorrect dosage, to a pharmacist dispensing the wrong medication. Whatever happened, if it caused you harm that could have been prevented, you may have grounds to claim.

Claims can be made by the person directly affected, by a parent or guardian on behalf of a child, or by a family member or representative where someone lacks capacity to manage their own legal affairs. If a prescription error led to a death, dependents of the deceased may be able to pursue a wrongful death claim.

To succeed in a claim, we first need to establish three things for you; first, that a healthcare professional owed you a duty of care – which all doctors, pharmacists and prescribers do – second, that they breached that duty by making an avoidable error. Thirdly, we need to demonstrate that the error directly caused you harm, whether that’s a physical injury or a worsening condition.

In most cases, you have three years from the date of the error – or from the date you first became aware that the medication caused harm – to begin legal proceedings. If you’re unsure whether you’re within that window, speak to us. There are exceptions, and we’ll give you an honest assessment of where you stand.

Example of a wrong prescription claim

Imagine a patient with a documented penicillin allergy, who is prescribed an antibiotic containing penicillin by a GP who failed to check their medical history.

After taking the medication, the patient suffers a severe allergic reaction requiring hospital treatment. If the prescriber had access to the allergy information and failed to review it, this could form the basis of a valid prescription error claim.

What compensation can help with

Covering the costs of recovery and easing financial pressure

Our team will work with you to build a thorough picture of everything the error has cost you, now and in the future, so that any settlement reflects the full impact of what happened. Seeking compensation after a prescription error, isn’t simply about acknowledging what went wrong. It’s about making sure you have the means to access any treatment you now need to recover properly.

A successful wrong prescription claim may help fund:

  • Medical expenses for any treatment required as a result of the error
  • Private treatment, corrective medication and therapy costs
  • Lost earnings if the error affected your ability to work
  • Ongoing care costs if long-term support or assistance is required
  • Psychological support and counselling for anxiety, depression or PTSD related to the error
  • Travel and transport costs for hospital visits and rehabilitation
  • Other financial losses linked to the medication mistake
Understanding the potential value

To illustrate what might be possible, here are some examples of cases we’ve settled for people who came to us for support. We secured a £4,100 settlement for a 94-year-old man who was given the incorrect dosage of a drug, leading to six months of pain and suffering. We also secured £5,500 for a client who was prescribed 10 times the intended dose of medication they actually needed. The value of a wrong prescription claim depends on the specific harm caused, your circumstances, and the longer-term impact on your health and finances. We’ll work with you to make sure your case reflects your experience.

Understanding special and general damages

When we calculate the value of a claim, we look at two categories of loss. The first is general damages, which compensates for the pain and disruption you’ve experienced, alongside the wider impact on your independence and quality of life. The second is special damages, which cover the financial costs you’ve faced as a direct result of what happened. Both matter, and both will be pursued in full.

You're not alone

We understand the physical, emotional and financial impact.

Many of our clients tell us they felt let down by a system they trusted, and that the experience left them anxious, confused, or reluctant to seek medical help again. Suffering harm because of a medication error is a deeply unsettling experience. You may be dealing with physical symptoms, a worsening health condition, or the aftermath of a serious reaction – while also trying to make sense of what went wrong and who was responsible.

The financial impact can add to that pressure. If the error has affected your ability to work, led to additional treatment costs, or required ongoing care, the practical consequences can feel just as overwhelming as the physical ones.

We’ve supported many people in exactly this position. We’re experienced in securing positive outcomes for people like you, and we work alongside independent experts who can help build a full picture of what went wrong and how your wellbeing is affected. We’ll handle the legal process from start to finish, keep you informed at every stage, and work to secure compensation that reflects the full impact of what happened to you.

FAQs about wrong prescription claims

How long do I have to make a wrong prescription claim?

In most cases, you have three years from the date of the prescription error, or from the date you first became aware that the error caused you harm. This is known as the ‘date of knowledge’.

There are exceptions. If a child has been harmed, a parent or guardian can bring a claim at any time before the child’s 18th birthday. Once they turn 18, they have until their 21st birthday to bring a claim themselves. For individuals who lack mental capacity, different timescales may apply – speak to us and we’ll advise on your specific situation.

If a prescription error resulted in a death, family members typically have three years from the date of death, or from the date the cause of death was confirmed. If you’re unsure whether you’re still within the time limit, contact us and we’ll give you an honest assessment.

What is the average compensation for a wrong prescription claim?

Compensation varies depending on the severity of the harm caused, how the error has affected your health and daily life, and what financial losses you’ve incurred. There is no fixed average – each case is assessed on its own facts.

Can I claim if I noticed the error before taking the medication?

If the mistake caused no actual harm, it may not qualify for compensation. However, if the error led to distress, anxiety, or financial losses – even without a physical injury – you may still have grounds to bring a claim. Speak to us and we’ll assess your situation honestly.

What happens if both my doctor and pharmacist made mistakes?

If multiple parties contributed to the prescription error, both may be held liable. Our solicitors will investigate all the circumstances of your case, identify everyone who bears responsibility, and ensure all liable parties are included in the claim.

How long does a wrong prescription claim typically take to settle?

The timeframe depends on the complexity of the case and whether liability is disputed. Straightforward claims may settle more quickly, while cases involving serious injury or contested liability can take considerably longer. We’ll keep you informed throughout the process so you always know what to expect at each stage.

What evidence is needed for a wrong prescription claim?

To build a strong claim, we typically gather:

  • Medical records showing your condition before and after the error
  • Pharmacy records confirming the incorrect prescription or dosage
  • Expert medical testimony from specialists who can assess the impact of the mistake
  • Witness statements from people who can confirm your experience
  • Financial loss records, including lost earnings, medical costs and ongoing care expenses

You don’t need to have all of this ready before contacting us. We’ll guide you through what’s needed and handle the evidence-gathering process on your behalf.

What support is offered during my wrong prescription claim?

From your first conversation with us, we’ll take the time to understand what happened and what matters most to you. We’ll explain the process clearly, keep you updated at every stage, and handle the legal complexity so you can focus on your recovery.

If you have questions at any point, our team is here to answer them. We aim to make the process as straightforward as possible, and we’ll always give you honest advice about your case.

What types of prescription errors can I claim for?

We handle a wide range of prescription error claims, including:

  • Incorrect dosage – whether too high or too low
  • Wrong medication type – prescribed or dispensed in error
  • Pharmacy dispensing mistakes, including mislabelled packaging or incorrect instructions
  • Failure to check a patient’s medical history, allergies or existing medications
  • Harmful drug interactions caused by incompatible prescriptions

If you’re unsure whether your situation qualifies, speak to us. We’ll give you a clear, honest assessment with no obligation.

How much does it cost to make a wrong prescription claim?

At Fletchers Solicitors, we work on a No Win No Fee basis, meaning there are no upfront costs and nothing to pay if your claim is unsuccessful. If your claim is successful, our fee is deducted from your final compensation. This means you can pursue your claim without any financial risk.

Who can make a prescription error claim?

Prescription error claims can be made by:

  • The affected individual, who was directly harmed due to a wrong prescription.
  • If a child has suffered harm from a prescription mistake, a parent or guardian can claim on their behalf.
  • A representative of someone lacking capacity: If an individual is unable to manage their legal affairs, a family member or appointed litigation friend can claim for them.
  • If a prescription error resulted in death, dependents or the estate of the deceased may pursue a wrongful death claim.
What are wrong prescription claims?

Wrong prescription claims arise when a medical professional makes an error in prescribing or dispensing medication, leading to avoidable harm. These errors can include issuing the wrong medication, providing incorrect dosage instructions, or failing to consider a patient’s medical history. From our clients’ experiences we have seen how all these errors can result in health complications.

Healthcare providers have a legal duty of care to ensure prescriptions are accurate and safe. When this duty is breached, patients may suffer adverse reactions, worsening health conditions, or long-term complications. In such cases, they may be entitled to pursue a prescription error claim.
