Can I make a medication error claim?

Medication error claims can be made when a mistake in prescribing, dispensing or administering medication causes you avoidable harm. This can happen in GP surgeries, hospitals or pharmacies, and the impact on your health and daily life can be significant. Medication errors can have serious consequences, and our specialist medical negligence team is here help.

You may be able to make a claim if you were given the wrong medication, the wrong dose or medication for the wrong length of time, or if a pharmacist dispensed the wrong drug or strength. These are just examples, and medication errors can happen in many different ways, including when a known allergy is overlooked, when a prescriber fails to check whether a new medication will interact with drugs you are already taking, or when a repeat prescription is issued without a proper review.

What is important to note, is that if the care you received fell below a reasonable standard, and you suffered harm as a result, a claim may be possible. If you are unsure whether your situation qualifies, or if some time has passed since the error occurred, it is still worth speaking to us. We will listen to what happened and tell you honestly whether you have a case.

Example of a medication error claim

Imagine a patient with a documented penicillin allergy who is prescribed an antibiotic belonging to the same drug family by their GP. The allergy is clearly recorded in their medical notes, but the prescription is issued without checking. After taking the medication, the patient suffers a severe allergic reaction requiring hospital treatment. If the prescribing doctor failed to review the patient’s allergy record before issuing the prescription, this could be a valid medication error claim.

What compensation can help with

Recovering lost income and covering future care

When you are given medication, you put trust in the GP or other medical professional who prescribed it. You rightly expect that you have been given the correct drug, the appropriate dose, and that it is safe for you to take. A medication error can break that trust and compromise your general health and wellbeing. Compensation might help you manage the effects more easily – perhaps by funding further treatment or therapies that you need to regain stability in your daily life.

A successful medication error claims may help fund:

  • Additional medical treatment and corrective care costs
  • Rehabilitation and physiotherapy
  • Psychological support and counselling
  • Loss of earnings, both current and future
  • Ongoing care and support needs
  • Travel and transport costs related to your recovery
  • Out-of-pocket expenses incurred as a result of the error
Understanding the potential value

We secured a five-figure settlement in a recent case where our client suffered a life-threatening internal bleed, after being given medication that was not appropriate for their condition. This was a serious and life-altering case, and the financial award helped to support our client’s recovery and ongoing care. This is just one example, and outcomes vary depending on each person’s circumstances. When medication is prescribed or supplied in a way that falls below the standard of care you should be able to rely on, the consequences can be significant. We work with independent medical experts to understand the full impact on your health and wellbeing and ensure your claim reflects that properly.

Understanding special and general damages

When valuing your medication error claim, we will consider two types of damages: general damages and special damages. General damages compensate for the pain, distress and disruption to your daily life, and special damages compensate for the financial losses you can evidence, including treatment, rehabilitation, lost earnings and travel costs. In more serious cases, compensation can also address the ongoing cost of managing a condition that has worsened or developed because of the error, as well as the psychological impact of experiencing an avoidable harm. We will look carefully at your circumstances so your claim reflects the full impact the medication issue has had on your life.

FAQs about medication error claims

How long will my medication error claim take?

It does take time to investigate your case properly to ensure we achieve the best possible outcome for you. Each case is unique and we will need to obtain copies of your medical records, dispensing and other relevant paperwork.

We also need to prepare witness statements and obtain independent medical reports to establish if your treatment has been negligent. If it has, we must then determine what harm you have suffered as a result of that negligence.

We must get an independent medical opinion about your current condition, what assistance you need immediately and what help you are likely to require on an ongoing basis. These things could all form part of your compensation claim. We would also need to take account of the financial losses you have incurred as a result of the negligence, such as lost earnings if you cannot return to work.

All this takes time, but is vital to properly assess and investigate your claim and recover the maximum amount of compensation to which you’re entitled. The attitude of the other side also influences how long a claim may take to settle.

Cases in which liability (i.e. fault) is admitted settle faster than if liability is denied.

Many claims settle through negotiation (sometimes even if liability is denied), but sometimes these cases can and do go to Trial. We can in certain cases obtain interim payments to fund any immediate needs that you might have as a result of the negligence.

What types of medication errors can I claim for?

Medication errors can happen in many ways, and you may still have a claim even if the mistake seems small.

Examples include being given the wrong drug or dose, receiving medication intended for another patient, being prescribed a drug you were known to be allergic to, or being given medicines that interact dangerously. Errors can also happen with repeat prescriptions if your medication is renewed without proper review.

If you are unsure whether your experience counts as a medication error, we can talk it through.

How do I prove a medication error claim?

In order to make a successful compensation claim for an injury caused by a prescription or medication error, it will be necessary to prove that those involved in prescribing or dispensing the drug to you were negligent (e.g. gave you the wrong drug or too high a dose of the right drug) and that you suffered harm or injury as a direct result.

Negligence on the part of a doctor, nurse or pharmacist could be established if the standard of care that they provided was below that which you could reasonably expect of similar professionals in that area. For example, a doctor or nurse could potentially be negligent if they gave you medication when your medical records showed you had a known allergy to that medication and as a result of taking the medication you had a severe reaction.

Other cases of potential negligence might exist where a doctor or nurse fails to check if the medication given will have an adverse effect when combined with any existing drugs that you might be taking, or where a chemist or pharmacist may not notice that the medicine they dispensed was the incorrect dosage for you and your condition. Every case will turn on its own specific facts.

Whatever the cause of the mistake, if you believe that you may have been the victim of a prescription or medication error, then the most important thing to do, first and foremost, is to seek medical help.

What is the time limit for making a medication error claim?

In most cases, you have three years from the date of the medication error – or from the date you became aware that the error caused your harm – to make a claim. It is important not to leave it too long, as gathering evidence and building a thorough case takes time.

If you are unsure whether you are still within the time limit, speak to us as soon as possible. There are some exceptions to the three-year rule, and we can advise you on your specific situation.

What evidence is needed for a medication error claim?

We will gather the evidence needed on your behalf, including your medical records, prescription information and any relevant documentation. This helps us understand how the error happened and the impact it has had on your health.

We also work with independent medical experts who can review your care and provide an opinion on whether the treatment you received fell below a reasonable standard.

The most important thing you can do is to seek medical advice if you have not already done so, and to keep a simple record of how your health has been affected.

Can I claim if the medication error was partially my fault?

Possibly. If you were partly responsible – for example, if you did not disclose relevant information about your medical history – this may affect your claim, but it does not necessarily prevent you from making one. This is known as contributory negligence, which means that the compensation awarded may be reduced to reflect your share of responsibility. We will give you honest advice about how this applies to your situation.

What support will I receive during my claim?

We will handle every part of the legal process on your behalf, keeping you informed at every stage in plain, clear language. If your case involves serious or ongoing harm, we will also look at whether interim payments can be secured to cover your immediate needs while your claim is underway.

Where appropriate, we can help you access the right medical care and rehabilitation support as early as possible – so you are not waiting until the end of your claim to get the help you need. Our goal is to make the process as straightforward as possible for you, so you can focus on your recovery.
