Allergy Not Recorded: Medical Negligence Claims in Ireland
Author: Gary Matthews, Principal Solicitor, Law Society of Ireland PC No. S8178 • 3rd Floor, Ormond Building, 31-36 Ormond Quay Upper, Dublin D07 • 01 903 6408 •
This is general information, not legal advice. Every case depends on its specific facts. Consult a solicitor for advice on your situation.
A failure to record your known drug allergy is a recognised breach of Irish healthcare standards. HIQA's National Standard for the Electronic Patient Summary requires that the allergy section shall identify the substance a patient reacts to (HIQA, 2018). Between 2016 and 2022, Irish hospitals reported 974 drug allergy incidents to the State Claims Agency's National Incident Management System (O'Keeffe et al., 2025), and in 37% of penicillin cases the patient's allergy was already on file (SCA, 2020). If a hospital, GP, or pharmacist failed to record, check, or communicate your allergy and you were harmed as a result, you may have a medical negligence claim for compensation in Ireland.
Quick answers: Your allergy should appear on every drug chart, prescription, and discharge summary. A blank allergy field is not the same as "no known allergies." If that blank led to you receiving a contraindicated drug, the prescribing and administration chain failed you. Two-year time limit applies from the date you knew (or should have known) the reaction was caused by a recording failure. Sources: HIQA Patient Summary Standard (2019); O'Keeffe et al., Irish Journal of Medical Science (2025).
Just had an allergic reaction in hospital or at your GP? Do these five things now:
1. Ask the treating team to confirm in writing which drug was given, the dose, and the time it was administered. 2. Ask whether an incident report has been filed on NIMS. You are entitled to know. 3. Photograph any visible reaction (rash, swelling, IV lines) while it is still present. 4. Write down the names of every doctor, nurse, and pharmacist involved while you remember them. 5. Keep all medication packaging, discharge paperwork, and prescription copies. Do not sign any waiver or statement about the incident without legal advice. Under the Patient Safety Act 2023, the hospital must disclose notifiable incidents to you. If nobody has mentioned an incident report, ask.

Do I have an allergy-not-recorded claim? Quick check
What counts as an allergy-not-recorded claim in Ireland?
An allergy-not-recorded claim arises when a healthcare provider fails to document, update, or communicate a patient's known drug allergy, and a contraindicated drug is then prescribed, dispensed, or administered, causing harm. The failure is administrative and systemic. It sits in the recording and communication chain, not in the clinical decision to treat.
An allergy-not-recorded claim is not the same as a dosage error, where the right drug is given in the wrong amount. The allergy case involves the wrong drug entirely, given because nobody recorded or checked the allergy. The distinction matters: a blank allergy box on a Kardex (the bedside prescription chart) provides a false sense of safety to every clinician who reads it.
Under Irish law, the test for medical negligence follows the principles set out in Dunne v National Maternity Hospital. You must show the healthcare provider owed you a duty of care, breached that duty by failing to meet the standard expected of a reasonably competent practitioner, and that the breach caused your injury. In allergy cases, the breach is typically clear-cut: HIQA standards require the allergy to be recorded, and it wasn't.
Does it matter whether your chart says "allergy" or "intolerance"?
Yes. The label on your medical record directly affects what drugs a prescriber considers safe to give you. A true drug allergy (mediated by the immune system, with a risk of anaphylaxis) is a hard contraindication. An intolerance (nausea from codeine or stomach upset from erythromycin) may only require caution, not avoidance. If your chart labels a genuine anaphylactic allergy as a mere "intolerance," a prescriber reading it might decide a related drug (such as a cephalosporin for a penicillin-allergic patient) is safe to give. That mislabelling is itself a recording failure.
HIQA's patient summary standard says the record SHOULD include the reaction type and severity. A chart entry that says only "penicillin" with no reaction detail fails to meet those SHOULD fields. The downstream risk is real: without knowing whether the original reaction was a rash or full anaphylaxis, the next clinician cannot properly assess cross-reactivity risk. The difference between "allergy" and "intolerance" on a drug chart is not a matter of clinical preference. It is a safety-critical classification, and getting it wrong can cause the same harm as leaving the field blank entirely.
What if they gave you a "different" drug that cross-reacted with your allergy?
A recorded allergy to one drug can mean a related drug is also dangerous, and failing to assess that cross-reactivity risk is a recognised recording and prescribing failure. The most common example in Irish hospitals involves penicillin and cephalosporins. A patient with a confirmed penicillin allergy faces a cross-reactivity risk of approximately 1-2% with cephalosporin antibiotics, but the risk is higher for specific combinations and much higher if the original penicillin reaction was anaphylaxis rather than a mild rash.
Cross-reactivity claims sit at the intersection of two failures. The first failure is in the recording: the allergy was documented but the reaction type and severity were not, so the prescriber couldn't assess the cross-reactivity risk properly. HIQA's SHOULD fields for reaction type and severity exist precisely to prevent this. The second failure is in the prescribing: even when an allergy is documented, the prescriber has a duty to check whether the new drug shares a chemical structure with the known allergen. A quick settlement can be tempting in cross-reactivity cases, but it may undervalue the claim if the psychological impact of a second allergic reaction (after believing the hospital was managing your allergy safely) is not separately assessed.
Cross-reactivity failures are not limited to antibiotics. Patients allergic to NSAIDs (such as ibuprofen) may react to aspirin. Patients allergic to one type of anaesthetic agent may react to a chemically similar alternative. If your records show a known allergy and you were given a drug from the same chemical family without the cross-reactivity risk being assessed or discussed with you, that prescribing decision may constitute a breach of duty even though the drug was not the exact substance you were allergic to.
How does an allergy get missed? Three failure points
An allergy recording failure is rarely a single mistake. It's a cascade across the medication-use chain. The State Claims Agency and the Irish Medication Safety Network (IMSN) break the medication process into three stages: prescribing, dispensing, and administration. An allergy can be lost at any of them.
Prescribing: the doctor doesn't check or record
The admitting doctor or GP fails to ask about allergies, or asks but doesn't transfer the answer onto the drug chart, electronic record, or referral letter. The Irish Medical Council's Guide to Professional Conduct and Ethics (9th Edition, effective ) requires doctors to keep accurate, up-to-date records, which includes drug allergies. A detail that catches many claimants off guard: even if the allergy was in the GP referral letter, it won't help if the hospital doctor didn't carry it onto the active prescription chart.
Dispensing: the pharmacist relies on a blank field
Hospital and community pharmacists have an independent duty to check for allergies and interactions before dispensing. Under Regulation 12 of the Regulation of Retail Pharmacy Businesses Regulations 2008, pharmacists must maintain a Patient Medication Record (PMR) for each patient. The PSI's Guidelines on the Keeping of Records (Version 4, March 2024) state that the PMR should contain "any known allergies or adverse drug reactions." When the allergy field on the prescription is blank and the pharmacy's own PMR also lacks allergy data, the pharmacist has no signal to investigate further. The IMSN calls this a "false sense of security." A pharmacy that dispensed a contraindicated drug without checking the PMR for allergy data may share liability alongside the prescriber.
Administration: the nurse gives the drug
The NIMS data confirms that 75.8% of drug allergy incidents in Irish hospitals occurred at the administration stage (O'Keeffe et al., 2025). The nurse preparing or giving the medication is the final safety check. If the allergy is not flagged on the drug chart, the wristband, or the electronic prescribing system, the nurse has no reason to stop. Nursing and midwifery staff reported 65.8% of all drug allergy incidents, indicating they're often the ones who catch these errors after the fact.
Electronic systems: when the alert exists but gets overridden
Hospitals with electronic prescribing systems may have the allergy coded in the database, yet the prescriber still orders the contraindicated drug. The difference between assessment and acceptance often comes down to "alert fatigue": clinicians who receive dozens of low-priority system warnings per shift learn to click past them. A published study of drug-allergy interaction alerts found that 46% of alerts for "definite anaphylaxis" were overridden by prescribers. Many Irish hospitals have not yet adopted electronic prescribing. Where paper Kardex charts remain in use, there is no automated alert at all, and the allergy check depends entirely on a human reading the box. Where electronic systems are in place, allergy data coded in one department may not trigger alerts in another if the systems lack interoperability. Both failure modes (no system and a system that is ignored) can ground a negligence claim.
Medication reconciliation: the safety step that should have caught it first
Before any of those three stages begin, there is an upstream safety process that should catch allergy recording gaps: medication reconciliation. The WHO identifies transitions of care (admission, ward transfer, discharge) as the highest-risk moments for medication errors. Both HIQA and the HSE require a formal medication reconciliation at every care transition. Reconciliation means a clinician compares the patient's current medication list, including allergies, against what is being prescribed in the new care setting. If reconciliation was not done at your admission, or was done but the allergy was not carried across, that is a separate provable failure from "the drug chart was blank." Reconciliation failures are often the easiest breach to prove because the process has a paper trail. Either the reconciliation form exists and shows the allergy was missed, or the form doesn't exist at all.
How common are allergy errors in Irish hospitals?
Irish hospitals reported 974 drug allergy incidents to NIMS between 2016 and 2022, with two-thirds rated moderate severity (meaning medical treatment was required). This is from a peer-reviewed study published in the Irish Journal of Medical Science (O'Keeffe et al., November 2025). Penicillins were involved in 16.2% of all drug allergy incidents by medication subgroup.
| Measure | Figure | Source |
|---|---|---|
| Total drug allergy incidents (2016-2022) | 974 | O'Keeffe et al. (2025) |
| Severity: moderate (treatment required) | 66.2% | O'Keeffe et al. (2025) |
| Stage: administration | 75.8% | O'Keeffe et al. (2025) |
| Penicillin cases where allergy was already known | 37% (15 of 41) | SCA Report (2020) |
| Allergic reaction as top injury in medication litigation | 9 of 48 paid claims | McCullagh et al. (2019) |
| Median total cost per medication claim | €60,991 | McCullagh et al. (2019) |
A separate six-year review of medication-related litigation in Ireland found that allergic reaction (including anaphylaxis) was the single most commonly pleaded injury, appearing in 9 of 48 claims that closed with a payment to the plaintiff. Five claims involved penicillin antibiotics, and in all but one the patient's allergy status was previously documented. Two of those penicillin cases had fatal outcomes (McCullagh et al., British Journal of Clinical Pharmacology, 2019).
Irish audit evidence: how often is the allergy box actually completed?
A clinical audit at the Department of Psychiatry, Midland Regional Hospital Portlaoise found that only 25% of inpatient medication charts had a completed allergy documentation section at baseline. After targeted intervention (introducing a formal assessment proforma with a designated allergy section and promoting awareness among NCHDs), compliance rose to 58.1%. In admission notes, allergy documentation went from 65% to 80.9%. Even after intervention, the gap never fully closed. Source: Irish Journal of Psychological Medicine (2018). While this audit was conducted in a psychiatric setting, the allergy documentation standards and medication chart formats are common across Irish hospital departments. These audits show allergy recording failures are not rare edge cases. They are a systemic weakness in Irish hospital documentation, and that systemic weakness is exactly what makes these claims provable.
Irish cases: when an unrecorded allergy led to death or serious harm
Murphy v HSE (High Court, April 2024): A 76-year-old woman was admitted to University Hospital Waterford in September 2018. Her notes recorded a penicillin allergy (anaphylaxis type). During the admission, she was given a penicillin-containing antibiotic. She collapsed, became unresponsive, and required emergency adrenalin. The antibiotic was discontinued and she was given an alternative. She was discharged five days later. The hospital's discharge summary failed to record the anaphylactic reaction or the allergy to that antibiotic. When she returned for review a month later, no reference was made to the episode. In January 2019, her GP, unaware of the hospital reaction, prescribed the same antibiotic for back pain. She suffered a fatal anaphylactic reaction. The family settled for €400,000 before Ms Justice Emily Egan, who described it as an "appalling loss" (Irish Times, April 2024).
Why it matters: The allergy was known inside the hospital. The anaphylactic reaction was witnessed and treated. Yet the discharge summary, the one document the GP relied on, omitted both. The GP had no way to know the drug was dangerous. The breach was a communication failure, not a clinical judgment error.
SCA penicillin fatality pattern (2011-2016): A six-year review of medication litigation managed by the State Claims Agency identified five penicillin allergy claims. In four of the five, the patient's allergy was already documented. Two resulted in death. The median total cost per medication-related claim was €60,991 (McCullagh et al., 2019).
Why it matters: The pattern is consistent. Known allergies being ignored or not carried forward is a recurring, documented problem in Irish hospitals, not an isolated incident.
What Irish standards should have been followed?
Multiple Irish regulatory frameworks require healthcare providers to record drug allergies. A blank allergy field breaches HIQA information standards, the Medical Council's ethics guide, and HSE medication safety policy.
HIQA National Standard for the Electronic Patient Summary
HIQA's standard states that the patient summary shall identify the substance the patient has a susceptibility to. It should also record the reaction type, severity, and onset date. Critically, if the patient has no allergies, the record must explicitly state "No Known Drug Allergies" (NKDA). A blank allergy field does not mean NKDA. It means nobody asked or nobody recorded the answer. Source: HIQA National Standard (December 2018).
| Field | Obligation | Legal significance if missing |
|---|---|---|
| Substance (the drug or substance you react to) | SHALL (mandatory) | Omission is an automatic breach of the national standard. Strongest evidence of failure. |
| Reaction type (rash, anaphylaxis, bronchospasm) | SHOULD | Without reaction type, downstream prescribers cannot assess severity or cross-reactivity risk. |
| Severity (mild, moderate, severe) | SHOULD | A missing severity field may lead a clinician to underestimate the danger and prescribe a related drug. |
| Onset date | SHOULD | Helps distinguish a confirmed allergy from an unverified patient report. Absence weakens the record's reliability. |
| No Known Allergies flag | SHOULD | A blank field does NOT satisfy this. The standard requires an explicit NKDA entry. Blank = failure to assess. |
The gap between SHALL and SHOULD carries legal weight. If only the substance was recorded but the reaction type was omitted, and a prescriber then gave a cross-reactive drug because they didn't know the original reaction was anaphylaxis, the missing SHOULD fields become the breach evidence. The standard was designed to prevent exactly that scenario.
Medical Council Guide to Professional Conduct and Ethics (9th Edition, 2024)
Section 38.1 of the Medical Council's Guide (effective 1 January 2024) requires doctors to keep accurate, legible, and up-to-date records contemporaneously. The Guide explicitly warns that poor records compromise a practitioner's ability to defend their clinical decisions. One aspect the official guidance doesn't cover: in practice, many Irish hospitals still use paper-based Kardex charts where allergy recording depends entirely on the admitting doctor writing it in ink.
IMSN Safety Alert on Allergy and Anaphylaxis (2016)
The Irish Medication Safety Network published a Safety Alert on Allergy and Anaphylaxis to Known Drug Allergens (October 2016) confirming that harm from known drug allergens is preventable. The alert requires allergy checking at every stage: prescribing, dispensing, and administration.
HSE Surgical Safety Checklist: the pre-anaesthesia allergy step
For patients undergoing surgery, the HSE's National Policy and Procedure for Safe Surgery requires a structured Surgical Safety Checklist based on the WHO model. Before anaesthesia induction, the "Sign In" phase includes an explicit allergy verification step: the team must confirm whether the patient has a known allergy. If this step was skipped or the allergy box was left blank, and the patient then received a contraindicated anaesthetic agent (such as a muscle relaxant or antibiotic prophylaxis containing a known allergen), the checklist failure becomes direct evidence of breach. The checklist is designed to be read aloud. If the anaesthetist or circulating nurse did not ask the allergy question, the surgical team records should reflect that gap. In surgical allergy cases, the central dispute is usually whether the checklist was actually completed verbally or merely ticked retrospectively.
A blank allergy field is not the same as "No Known Drug Allergies." HIQA information standards require an explicit NKDA entry. If the field was left blank, it indicates a failure to assess your allergy status, and this failure can form the basis of a negligence claim.
What the Patient Safety Act 2023 changed for allergy claims
Since , a patient death associated with a medication error is a notifiable incident under the Patient Safety (Notifiable Incidents and Open Disclosure) Act 2023. Schedule 1, Item 1.8 of the Act covers an "unintended and unanticipated patient death associated with a medication error." If a failure to record an allergy led to a fatal anaphylactic reaction, the hospital must now:
Disclose the incident to the patient's family under mandatory open disclosure rules. Report the incident to HIQA within 7 calendar days via NIMS. The Act applies to both public and private health services. Non-compliance carries a criminal sanction of up to €5,000 (Class A fine under Section 77).
England has had a statutory duty of candour since 2014 under Regulation 20 of the Health and Social Care Act 2008 (Regulated Activities) Regulations 2014, enforced by the CQC. Ireland's 2023 Act differs in three ways that matter for allergy claims. First, the Irish Act carries criminal sanctions (a Class A fine of up to €5,000 under Section 77) directed specifically at health service providers who fail to disclose a notifiable incident. Second, Ireland's Act explicitly protects the apology: Section 10 provides that information and apologies made during the disclosure meeting cannot be used as an admission of fault in subsequent legal proceedings. Third, in Ireland, prior to the 2023 Act, open disclosure was only voluntary under Part 4 of the Civil Liability (Amendment) Act 2017. The mandatory regime is new. The timing matters more than most guides suggest: if your family has not been offered open disclosure following a severe allergy-related medication incident, that failure to disclose may itself be a breach of the Act.
Where allergy recording fails: GP, hospital, pharmacy, discharge
Allergy documentation failures happen in specific, recognisable settings. The failure pattern differs depending on where in the Irish healthcare system the error occurs.
If the failure happened at your GP: Your GP prescribed a drug you told them you were allergic to. Check whether the allergy appears in their electronic patient record. GPs in Ireland use systems like Socrates or Health One, which have allergy alert fields. If the allergy was entered but the alert was overridden, the question becomes why. If it was never entered despite you telling the GP, the failure is straightforward.
If the failure happened at hospital admission: You told the triage nurse about your allergy, but it didn't make it onto the drug chart or electronic admission record. This is the most common scenario in our experience, especially in busy emergency departments where handover omissions occur.
If the failure happened during a care transfer: You were referred from a GP to a hospital consultant, or moved between wards. The allergy information from the referral letter or previous ward notes wasn't carried forward to the new team's active drug chart. Transition-of-care failures are a recognised high-risk point for allergy errors.
If the failure happened at the pharmacy: Your community pharmacist dispensed a drug you're allergic to without checking your medication history. The PSI requires pharmacists to maintain patient medication records, including allergy status.
If the failure happened at discharge: You were discharged from hospital with a medication you're allergic to because the allergy wasn't included in the discharge summary sent to your GP. The GP then continues the prescription. HIQA's patient summary standard specifically requires allergy data in discharge documentation.
Proving your claim: the four legal tests applied to allergy failures
Irish medical negligence law requires you to prove four elements: duty of care, breach, causation, and damage. For allergy-not-recorded claims, the breach is often the clearest element because Irish standards explicitly require allergy documentation. For detailed guidance on how to prove medical negligence generally, see our step-by-step guide to proving medical negligence in Ireland.
| Element | What you must show | How allergy cases work |
|---|---|---|
| Duty of care | A doctor-patient (or provider-patient) relationship existed | Usually straightforward: you were a patient in their care |
| Breach of duty | Care fell below the standard of a reasonably competent practitioner | HIQA, Medical Council, and IMSN standards explicitly require allergy recording. A blank field breaches these standards. |
| Causation | The breach directly caused or materially contributed to your injury | If the allergy had been recorded, the drug would not have been given, and the reaction would not have occurred |
| Damage | You suffered a compensable injury | Allergic reaction, anaphylaxis, prolonged hospital stay, psychological harm, or death |
Causation is where defence teams push hardest. They may argue the drug would have been given regardless, or that you failed to tell staff about your allergy. The HSE's "Know Check Ask" campaign encourages patients to carry a medicines list. However, this patient-side initiative does not remove the clinician's duty to actively ask, record, and verify allergy status before prescribing. The legal burden remains on the healthcare provider. Running the Allergy Record Audit before instructing an expert helps your solicitor pinpoint exactly which link in the chain broke.
Who do you actually claim against in an allergy case?
Allergy-not-recorded claims often involve more than one defendant, because the recording failure typically spans multiple people and organisations. Your solicitor can name all potentially liable parties in the same proceedings. The court then apportions responsibility.
Where did the allergy recording failure happen?
Select the setting where your allergy was missed. This general guidance shows the likely defendant and key records to request. It is not legal advice.
If the error happened in a public hospital (HSE): The claim is managed by the State Claims Agency under the Clinical Indemnity Scheme. The SCA handles the defence and any settlement on behalf of the HSE. You do not sue the individual doctor or nurse personally. You claim against the HSE as the employer.
If the error happened in a private hospital: The hospital's own professional indemnity insurer handles the defence. Private hospitals are not covered by the State Claims Agency. Since September 2024, the Patient Safety Act 2023 extends HIQA's regulatory oversight to private hospitals for the first time.
If the error happened at a GP practice: GPs carry personal professional indemnity insurance, typically through Medisec Ireland or the Medical Protection Society (MPS). The claim is against the GP personally (or the practice, depending on the structure). GP claims do not go through the State Claims Agency.
If the error happened at a pharmacy: Pharmacists are required by the PSI to hold professional indemnity insurance. The claim is against the pharmacist or pharmacy business. If the pharmacist dispensed a contraindicated drug because the prescription's allergy field was blank, both the prescriber and the dispenser can be named as defendants.
In the Murphy case, the hospital failed to include the allergy in the discharge summary and the GP then unknowingly re-prescribed the drug. Both the hospital (via the HSE) and the prescribing chain could be liable. The IRB does NOT handle medical negligence claims in Ireland. Your claim goes directly through the court process, typically the High Court for significant injuries. From handling these cases, the sticking point is usually getting records from multiple defendants who each blame the other for the gap.
What evidence do you need for an allergy-not-recorded claim?
The strongest evidence in these cases comes from the medical records themselves. You are looking for the gap: the place where your allergy should have been recorded and wasn't. We call this the Allergy Record Audit: a systematic check of five record types to identify exactly where documentation failed. For guidance on how to request your records, see our page on requesting medical records in Ireland.
The Allergy Record Audit targets these records and documents:
GP patient record (check the allergy alert field in their software system). Hospital admission clerking form and Kardex (the bedside drug chart). Electronic prescribing system allergy entries (if the hospital uses one). HSE Surgical Safety Checklist (if surgery was involved). Discharge summary sent to GP (check whether allergy was included). Pharmacy dispensing records (community or hospital). Nursing notes (look for any reference to allergy reported verbally). Incident report filed on NIMS (if one exists). Ambulance or paramedic records (if relevant to the admission).
Allergy Record Audit: Check Your Records
Tick each record you have obtained and reviewed. The more gaps you find, the stronger the evidence of a documentation breach. This is general guidance, not legal advice.
An independent medical expert will review these records and provide an opinion on whether the allergy should have been recorded and whether recording it would have prevented the harm. In Ireland, experts are often sourced from the UK to ensure impartiality, given the small size of the Irish medical community.
What if you suspect the allergy box was filled in after the reaction?
Retrospective completion or alteration of medical records after an adverse event is a known problem, and it can be detected. The Medical Council's Guide (Section 38.1) requires records to be made contemporaneously. If the allergy box on your drug chart was blank when the drug was administered but appears to be ticked when you receive your records weeks later, that discrepancy itself is evidence of awareness that the record was deficient.
Electronic health records maintain audit trails that log every entry, amendment, and the exact time it was made. If the allergy entry was added after the reaction occurred, the timestamp will show it. Paper records are harder to interrogate but not impossible. Handwriting analysis can determine whether entries were made by the same person at different times. Ink analysis (though rarely needed) can distinguish entries made at different sittings. The sequence of entries on a physical Kardex can reveal whether the allergy box was completed in a different pen or ink colour from the original admission clerking.
Record alteration does not help the defendant. If a court or expert finds that records were amended after an incident without a transparent correction trail, the alteration undermines the defendant's credibility on every contested fact. The Guidelines state that corrections to records should be made by drawing a single line through the original entry (leaving it legible), adding the correction, and signing and dating the amendment. Any alteration that does not follow this protocol raises questions about what the record originally said. If you suspect records have been changed, tell your solicitor before requesting the file. Your solicitor can request the electronic audit trail alongside the records, and can preserve the paper originals before any further changes are made.
Compensation for allergy negligence in Ireland
Compensation for an allergy-not-recorded claim follows the same framework as any medical negligence case in Ireland, based on the Judicial Council's Personal Injuries Guidelines (2021). Awards depend on the severity of the reaction, the period of recovery, any lasting effects, and proven financial losses. For a full breakdown, see our medical negligence compensation guide.
| Injury type | Indicative range | Relevant factors |
|---|---|---|
| Severe anaphylaxis with ICU admission and lasting effects | €58,400 to €117,000+ (general damages) | Duration of ICU stay, organ damage, ongoing anxiety, IBS or incontinence |
| Moderate allergic reaction with hospital admission | €23,300 to €52,500 | Length of stay, treatment required, recovery period |
| Mild reaction with short-term effects | €8,000 to €23,300 | Rash, short illness, full recovery within weeks |
| Fatal claim (dependants) | Solatium + dependency + funeral | Civil Liability Act 1961 applies. Solatium capped at €35,000 total. |
Ranges derived from Personal Injuries Guidelines (2021) and draft second edition. Every case is different. Awards vary based on individual facts and evidence. Consult a solicitor for an assessment of your specific situation.
Special damages (financial losses) are calculated separately and may include medical treatment costs, lost earnings during recovery, travel expenses for treatment, future care needs, and home adaptations. These are added on top of general damages for pain and suffering.
Psychological injury after an allergic reaction: a separate head of damage
Anaphylaxis is a terrifying experience, and the psychological aftermath is independently compensable in Ireland. The McCullagh litigation review found that PTSD was pleaded in 8 of 48 medication-related claims (McCullagh et al., 2019), making it the second most common injury after allergic reaction itself. Patients who survived anaphylaxis from an unrecorded allergy commonly describe the feeling of not being able to breathe, losing consciousness, and believing they were dying. The resulting anxiety, fear of hospitals, fear of all medication, and diagnosed PTSD can persist long after the physical recovery is complete.
Psychological injury does NOT need to involve a physical brain injury. Anxiety, PTSD, and adjustment disorder caused by the traumatic experience of anaphylaxis are compensable as separate heads of damage on top of the physical injury award. The Personal Injuries Guidelines include specific brackets for psychological and psychiatric conditions. If your allergy reaction left you with lasting fear or avoidance behaviour around medication or medical settings, that harm has its own compensation value. Your solicitor should arrange for a psychological or psychiatric assessment alongside the physical expert report.
Time limits for allergy-not-recorded claims in Ireland
The standard time limit is two years from the date of knowledge under the Statute of Limitations 1957 (as amended). The "date of knowledge" is the date you knew, or should reasonably have known, that your injury was caused by the failure to record the allergy. This may be later than the date of the reaction itself. In England and Wales, the limitation period for personal injury is three years under the Limitation Act 1980. Ireland's two-year window is shorter, meaning claimants who move between jurisdictions or rely on UK-based guidance may underestimate the urgency.
If the claimant is an adult: Two years from the date of knowledge. If you had a severe allergic reaction and only later discovered the allergy was not recorded, the clock starts when you learned of the recording failure.
If the claimant is a child: The two-year clock does not start until the child turns 18. A claim can be brought any time before the child's 20th birthday.
If the claimant lacks mental capacity: The limitation period may be paused until capacity is regained.
For detailed guidance on limitation periods, including the "date of knowledge" concept, see our dedicated page on time limits for medical negligence in Ireland.

What if your situation doesn't fit the standard pattern?
Not every allergy claim is straightforward. The sections above cover the core process, but many people find their case has a wrinkle. The questions below address the edge cases, procedural doubts, and specific scenarios that come up most often when clients contact us about allergy recording failures. If your situation doesn't match any of them, that doesn't mean you lack a claim. It means you need individual advice.
Common Questions
Is a blank allergy field on my chart the same as "no known allergies"?
No. In Ireland, under HIQA's National Standard for the Electronic Patient Summary, a blank allergy field indicates a failure to assess your allergy status. If a patient has no allergies, the record must explicitly state "No Known Drug Allergies" (NKDA). The absence of an entry is clinically unacceptable.
Why it matters: A blank field gives downstream clinicians a false sense of safety and is direct evidence of a documentation breach.
Next step: Request your medical records and check the allergy section on the admission form, Kardex, and discharge summary.
What if I told the nurse about my allergy but it wasn't written down?
You may still have a valid claim. In Ireland, the duty to record your allergy falls on the healthcare provider, not on you. Even if the information was communicated verbally, the failure to document it in the official record is the provider's breach.
Witness evidence (from a family member who was present, for example) and nursing notes that reference verbal communication can support your claim. The HSE's "Know Check Ask" campaign encourages patients to carry a medicines list, but this does not transfer the recording duty to you.
Next step: Gather any witnesses who heard you mention the allergy and request the full nursing notes.
How common are penicillin allergy errors in Ireland?
Penicillin is the most frequently cited drug in Irish allergy litigation. The State Claims Agency reported 41 penicillin allergy incidents in 2017-2018 alone, and in 37% of those cases the patient's allergy was already documented (SCA, 2020). Co-amoxiclav (Augmentin) and piperacillin/tazobactam (Tazocin) accounted for 90% of penicillin allergy incidents.
Why it matters: Penicillin allergy is one of the most common drug allergies. Failing to check for it before prescribing an antibiotic containing penicillin is a well-recognised, preventable error.
Next step: If you had an allergic reaction to a penicillin-containing antibiotic, contact a medical negligence solicitor promptly.
Can I claim if a family member died from an unrecorded allergy?
Yes. In Ireland, dependants and family members can bring a wrongful death claim under the Civil Liability Act 1961. Since September 2024, a death from a medication error is also a notifiable incident under the Patient Safety Act 2023, triggering mandatory open disclosure to the family.
The family can claim for solatium (capped at €35,000 total across all dependants under the Civil Liability Act 1961, s.49), dependency (financial support lost), funeral costs, and mental distress. If the hospital has not proactively disclosed the incident, ask your solicitor to request the NIMS incident report.
Next step: Seek legal advice immediately to protect limitation periods. Call 01 903 6408.
Can I claim against my GP for prescribing a drug I'm allergic to?
Yes, if the GP failed to record or check your allergy and that failure caused you harm. GP software systems in Ireland include allergy alert fields. If your allergy was in the system and the GP overrode the alert without justification, or if the allergy was never entered despite you reporting it, both scenarios can support a negligence claim.
Why it matters: GP negligence claims follow a different route to hospital claims and do not go through the Injuries Resolution Board (IRB). Expert evidence is required.
Next step: Our GP negligence claims guide explains the process.
Can I claim against a pharmacist who dispensed a drug I'm allergic to?
In Ireland, pharmacists have an independent professional duty to check for allergies before dispensing. If your pharmacist had access to your medication history (which they should maintain under PSI guidelines) and failed to flag the allergy, they may share liability. In many cases, both the prescriber and the dispenser are at fault.
Next step: Request your pharmacy dispensing records and your GP prescription records to compare what was prescribed versus what should have been flagged.
Will the hospital argue I should have told them about my allergy?
Defence teams sometimes raise contributory negligence, arguing the patient failed to communicate their allergy. In Ireland, the legal duty to actively solicit, record, and verify allergy status rests on the healthcare provider, not the patient. The Medical Council's Guide requires doctors to take a complete history. If you were unable to communicate (unconscious, confused, or a child), this defence fails entirely.
Why it matters: The "Know Check Ask" campaign encourages patient participation but does not shift the legal burden from the clinician.
Should the hospital have told me about the allergy error under the Patient Safety Act?
If the error caused serious harm or death, yes. The Patient Safety (Notifiable Incidents and Open Disclosure) Act 2023 requires mandatory disclosure of notifiable incidents, including deaths associated with medication errors. The hospital must notify HIQA within 7 days and disclose to the patient or family in a timely, compassionate manner.
If you have not been offered open disclosure following a severe allergic reaction, ask your solicitor to make a formal inquiry.
Next step: Patient Safety Act 2023, Schedule 1 lists all notifiable incidents.
