By Cat Way. Last updated 30 October 2025. When we are sick, we trust that healthcare professionals will treat us to the correct standard. Unfortunately, if that doesn’t happen, it can lead to patients suffering allergic reactions to their medication that would have otherwise been avoidable. We understand how devastating this can be for your health and finances, and we could help you make a drug allergic reaction claim for your unnecessary suffering and loss.
Our medical negligence solicitors have years of experience, always taking an empathetic approach throughout the drug allergic reaction compensation claims process. If you claim with one of them, you can rest assured that they will be by your side from start to finish, so you stay focused on your recovery. Please feel free to contact our team for more information.
What You Need To Know About Drug Allergy Claims:
- How do medical professionals check for drug allergies? They may consult with patient records, alongside skin prick or blood tests.
- What are the symptoms of a drug allergy? Some common symptoms of a drug allergy include sneezing, a runny nose, breathlessness, wheezing, or hives.
- How can a drug allergy be treated? Drug allergies can be treated through antihistamines, steroids, or adrenaline auto-injectors (in the case of severe allergic reactions).
- How do drug allergic reactions occur because of medical negligence? They may occur if healthcare professionals misread prescriptions, fail to check for allergies, or administer the wrong medicine.
- Do I have to preserve the medicine packaging for my drug allergy claim? While it isn’t necessary, retaining the packaging and other evidence can help support your claim.
How To Make A Drug Allergic Reaction Claim
Having an allergic reaction to your medication won’t always form the basis of a valid claim; allergic reactions are fairly common, and many don’t have serious consequences. However, if you can prove that medical negligence occurred, then you may be able to make a drug allergic reaction claim. But what is medical negligence?
Essentially, medical negligence occurs when:
- You are owed a duty of care
- This duty is breached
- You suffer avoidable harm as a result
All medical professionals, from surgeons to pharmacists, owe their patients a duty of care. This applies as soon as they treat you, and it means they need to make sure that they provide care that meets a minimum standard.
The steps that your medical professional needs to take to fulfil this duty of care can vary. For example, the Royal Pharmaceutical Society provides standards and guidance for its members to follow.
For example, if you have a known allergy to penicillin and it says so in your chart, you should not be prescribed penicillin. However, if a doctor diagnosed your rash as a bacterial infection and prescribed penicillin anyway, this could be a breach of their duty of care. If you then had an allergic reaction that caused you to go into cardiac arrest, you could potentially make a drug allergic reaction compensation claim.

Drug Allergic Reaction Compensation Claims Against A GP
When you visit your GP because you’re unwell, they have a duty of care to ensure your safety. This means that they should follow correct procedures when treating you. It also means they should use systems that are effective. For instance, they should have a system for recording any drugs to which you are allergic. If these systems are inadequate or aren’t used when prescribing medicines, you could receive medication that you’re allergic to. If that happens, you could be entitled to claim compensation for any suffering caused.
Drug Allergic Reaction Compensation Claims Against A Hospital
In the same way as a GP, a hospital doctor should check your medical records before prescribing medicines. There are many scenarios within a hospital when this might happen. For instance:
- During or following surgery.
- While on a ward recovering from treatment.
- When being discharged.
If at any point you are prescribed medication that you’re known to be allergic to, you could be entitled to compensation if it caused you suffering. That could even be the case in emergency situations. For instance, if you were incapacitated and couldn’t tell the doctor but the allergen was listed in your medical records, then you could still be entitled to make a drug allergic reaction claim.
Drug Allergic Reaction Compensation Claims Against A Pharmacy
While prescriptions are written by doctors, it is a pharmacist who has the responsibility for dispensing the correct medication. While the doctor will make checks for allergens prior to prescribing, if the pharmacist makes a mistake, those checks could be in vain. In this scenario, you could sue the pharmacist for any suffering their mistake caused.
The same is true when you purchase over the counter medication. Failure to highlight an allergen could also entitle you to make a drug allergic reaction claim.
Claiming For An Allergic Reaction To Drugs – Evidence You Could Gather
If you have had an allergic reaction to drugs that a medical professional prescribed to you, you might be able to make a medical negligence claim. However, you will need to prove that you suffered unnecessary harm due to a medical professional breaching their duty of care.
An important step in the claims process is gathering evidence to help support your case. Evidence can help establish that medical negligence occurred and give details on the harm you experienced as a result, including the reactions to the drugs you experienced and the impact this has had on your life.
Some examples of evidence that you could collect include:
- Medical records: Your medical records may show what medication you were given and might record any allergies to drugs that you had previously disclosed. This can help establish who is liable for your reaction.
- Correspondence with your healthcare practitioner regarding the treatment you received.
- A diary detailing the symptoms you suffered and how they have impacted your daily life.
These are just a few examples of the kinds of evidence you could use to support your claim. To find out how one of our solicitors could help you collect evidence and further strengthen your claim, you can contact our team of friendly advisors.
Drug Allergic Reaction Compensation Claims Calculator
Now that we’ve explained how and why an allergic reaction to medical treatment might happen, we’re going to look at compensation amounts. The amount of compensation that could be paid is different in each case. Therefore, instead of using a personal injury claims calculator, we’ve provided the table below.
The entries in the table are based on a document known as the Judicial College Guidelines (JCG), except for the first row. This document is used by courts, insurers and solicitors to value payouts, as it contains suggested brackets for compensation relating to various injuries. None of the rows guarantees compensation.
| Injury | Compensation |
|---|---|
| Severe Harm And Special Damages, Including The Cost Of Medical Treatments And Lost Earnings | Up to £150,000+ |
| Injuries To The Digestive System (i) | £46,900 to £64,070 |
| Injuries To The Digestive System (ii) | £11,640 to £23,430 |
| Injuries To The Digestive System (iii) | £4,820 to £11,640 |
| Injuries To The Digestive System (iv) | £1,110 to £4,820 |
| Severe Psychiatric Damage | £66,920 to £141,240 |
| Moderately Severe Psychiatric Damage | £23,270 to £66,920 |
| Severe PTSD | £73,050 to £122,850 |
| Moderately Severe PTSD | £28,250 to £73,050 |
You’ll notice that each injury is compensated based on how severe it was. Therefore, it’s important that your solicitor can show the true extent of your suffering. Otherwise, you might not receive the correct level of compensation. To help with this, our solicitors arrange for a medical assessment by an independent doctor as part of the drug allergic reaction claim process. This will usually be arranged locally to try and reduce the amount of travelling required.
Special Damages For A Medication Allergy Claim
A personal injury solicitor or medical negligence solicitor will include general and special damages in your claim. General damages are claimed to compensate you for the pain, suffering and loss of amenity caused by your injuries. The table from the previous section included examples of general damages amounts. Therefore, in this section, we’ll explain what special damages cover. Essentially, they are paid to compensate you for any financial losses caused by your injuries. They could include:
- Medical Expenses. It’s possible that you’ll have to pay for prescription medication or over the counter treatments while recovering from the allergic reaction. Therefore, you could include these expenses in your claim.
- Travel Costs. If you need to travel to and from medical appointments while recovering, you might incur fuel, parking or public transport costs. These could also be claimed back.
- Care Expenses. The cost of a carer is something else you could claim back if one is required to assist you while recovering. This could include professional carer’s fees or the time of a family member who supported you.
- Lost Earnings. It’s possible that any time off work to recover or attend medical appointments could result in reduced pay. If that’s the case, you could ask for the lost earnings back.
- Future Loss of Income. Finally, if your allergic reaction impacts on your ability to work in future, it could cause future lost income too. Factors considered in this part of your claim include your age, salary and job prospects.
You’ll need to provide evidence to support the special damages part of your drug allergic reaction claim. This could include receipts and bank statements. It can also be useful to keep a diary of your expenses so it’s easier to explain them to your solicitor when asked.
No Win No Fee Drug Allergic Reaction Compensation Claims
We believe you should be able to claim compensation without worrying about the costs involved. That’s the reason that we work on a No Win, No Fee basis. This service gives you peace of mind and the confidence to claim because the financial risk is reduced.
The solicitor will begin by assessing your claim to see if a successful outcome is possible. If they think there is, you’ll be given a No Win, No Fee agreement to sign. This is also referred to as a Conditional Fee Agreement (CFA).
The CFA will explain that there are no upfront fees to pay and nothing to pay during the claim either. It will also explain that the solicitor will ask for a contribution towards their fees if they win the case for you. This is called a success fee and it’s deducted from your compensation at the end of the claim. Don’t worry, though, as the percentage for these success fees is legally capped.
To find out if you could make a drug allergic reaction claim on a No Win, No Fee basis, please call an advisor today.
