Trace the medicine through five handovers
A medication error is rarely explained by the box alone. The drug may have been chosen incorrectly, written ambiguously, transcribed into the wrong chart, dispensed in the wrong strength, administered to the wrong patient or continued without appropriate monitoring. A useful Kenyan claim review follows the medicine through five handovers: prescribing, transcription, dispensing, administration and monitoring.
That sequence also prevents an easy mistake in the legal analysis. A harmful reaction to a correctly selected and supplied medicine is not automatically negligence. Neither is every prescribing or dispensing error compensable. The evidence must identify the actual departure, the person or system responsible, and the injury that the departure probably caused or made worse.
Seek clinical help before collecting proof
If the patient has breathing difficulty, swelling, collapse, severe rash, confusion, seizures, persistent vomiting, heavy bleeding, marked drowsiness or another acute change after medication, obtain urgent medical help. Take the container, label, remaining tablets or liquid and current medication list if this can be done without delay. Do not induce vomiting, alter a dose or abruptly stop an essential medicine unless a qualified clinician directs it.
Tell the treating team the name on the label, strength, quantity taken, route, time, allergies, other medicines and the symptoms observed. Ask that these details and the immediate findings are placed in the clinical record. Preserve discharge summaries, laboratory results, treatment for the reaction and the clinician’s working diagnosis.
The Pharmacy and Poisons Board provides official channels for reporting adverse events and suspected poor-quality medicines. A safety report can support regulatory surveillance, but it does not itself establish negligence or replace urgent treatment. Keep the submission and reference number separate from the civil evidence file.
Freeze the physical and digital evidence
Photograph every side of the original container, blister, sachet, ampoule or bottle before moving its contents. Capture the patient name, drug name, strength, dosage instructions, dispensing date, pharmacy, batch and expiry details. Keep the original receipt and bag. Do not combine tablets from different packages or mark the label. Store the product safely as directed, away from children, while clinical advice is obtained.
Save the original prescription or electronic message, not only a retyped list. Preserve pharmacy texts, refill notifications, mobile payment records and any call log showing clarification. If the error occurred in hospital, request the medication chart, prescribing order, pharmacy issue record, nursing administration record, stock or controlled-drug documentation where relevant, observation chart and incident material that can lawfully be disclosed.
A later corrected label or prescription should be retained as a new version. Record who supplied it, when and why. Do not surrender the only original without a receipt identifying the item and purpose. Where a regulator or laboratory needs the product, document the transfer and maintain an accountable chain of custody.
Handover one: what was prescribed and why?
Start with the consultation record. Identify the diagnosis or symptom being treated, available test results, allergies, pregnancy status where relevant, age, weight, kidney or liver information, other medicines and the intended duration. Then compare those facts with the drug, dose, route, frequency and instructions actually ordered.
The information obligation in section 8 of the Health Act extends to the user’s health position and the available options, with their relevant advantages, risks, expense and consequences. The informed-consent rule appears separately in section 9 and operates subject to the exceptions stated there. The practical question is what information mattered for this patient: the purpose of the medicine, important risks, alternatives, interaction warnings, monitoring and what to do if a serious reaction appeared.
A poor outcome does not prove that the initial choice was unreasonable. The prescriber may have selected an accepted option and the patient experienced an unpredictable reaction. A specialty-matched expert should assess the decision using the information reasonably available at the time, not hindsight created by the later injury.
Handover two: was the order copied correctly?
Between prescription and supply, an order may be entered into a hospital chart, electronic system, discharge summary or pharmacy queue. Compare each version character by character. Check the medicine, formulation, strength, decimal point, units, route, frequency, duration, stop date and patient identifier. Preserve the sequence rather than presenting only the final version.
Where handwriting or an abbreviation is disputed, do not guess at its meaning. Record the ambiguity and look for contemporaneous clarification: a call to the prescriber, pharmacist note, electronic audit entry or corrected order. An expert can explain whether the ambiguity should have prompted clarification and which professional controlled the next step.
Handover three: inspect the dispensing transaction
Compare the prescription with the product and label supplied. Determine whether the pharmacy selected the correct active ingredient, formulation, strength, quantity and instructions for the correct patient. If a generic product was supplied, distinguish an authorised equivalent from an entirely different medicine. Note any counselling, measuring device, storage direction or warning provided, but keep the patient’s recollection separate from documents.
The Pharmacy and Poisons Act governs pharmacy practice and trade in drugs and poisons, while the Pharmacy and Poisons Board regulates within its statutory mandate. Verify the pharmacy premises and the professional involved through official material where possible. A regulatory concern about licensing or supply may be important, but civil liability still requires proof connecting the particular failure to injury.
If the suspected problem is contamination, falsification, degradation or a recalled batch rather than selection or labelling, preserve batch and expiry details. Check the Board’s official safety communications and recalls. Do not send a sample to an informal tester and treat the result as conclusive; product identity and quality may require an accredited analysis with a documented chain of custody.
Handover four: establish what the patient actually received
In a facility case, the written order and dispensed item do not prove administration. Build a dose table from the medication administration record: scheduled time, actual time, dose, route, person recording it, omission or refusal, and any later correction. Cross-check infusion sheets, nursing notes, observation charts and stock movement where relevant.
At home, use the remaining quantity, refill dates, caregiver notes and the patient’s account to reconstruct use. Avoid pretending the count is exact if tablets were lost, shared or discarded. If the patient misunderstood the label, examine whether the direction was clear and what counselling occurred. If the patient knowingly took more than instructed, disclose that fact; it may affect causation and responsibility.
Handover five: identify the missed monitoring point
Some medicines require assessment before starting, review after dose changes or testing during treatment. The necessary monitoring depends on the particular drug and patient. Ask the relevant expert what was reasonably indicated, what results were available, who was expected to review them and what action should have followed.
Create a results timeline showing the first abnormal symptom or test, the first report to a clinician or pharmacist, advice given, later doses, referral and treatment. This can distinguish a reasonable initial prescription followed by a negligent failure to react from a case in which the complication was recognised promptly. Do not invent a universal monitoring interval or stopping rule.
Connect the error to a defined injury
Write a short causal hypothesis before instructing an expert: the patient received a named drug or dose through an identified error; the medicine can cause the observed mechanism; the timing and clinical findings fit that mechanism; and competing explanations are less likely. Each part needs evidence. Temporal sequence alone is not enough.
Relevant proof may include drug levels, kidney or liver tests, clotting results, electrocardiograms, imaging, allergy assessment, toxicology, treatment response and a documented dechallenge or rechallenge where this occurred clinically. No one should deliberately repeat a suspected harmful medicine to create evidence.
The expert must consider the underlying illness, other medicines, infection, alcohol or substance exposure and independent disease. The Herman Nyangala Tsuma decision is a useful reminder that medical negligence is evaluated through evidence about duty, clinical conduct and outcome, not inferred simply because treatment was followed by harm.
Separate prescriber, pharmacy, facility and manufacturer issues
Map responsibility to the stage controlled. A prescriber may be responsible for selection, dose or interaction assessment. A pharmacy may control interpretation, product selection, labelling and counselling. A facility may control electronic systems, storage, staffing and administration processes. A manufacturer or distributor issue may concern product quality, but it should not be alleged merely because the medicine produced a recognised adverse effect.
Obtain the full legal names of the practitioners, pharmacy, facility and any company identified on the package. Use receipts, admission documents, registers and official searches. Do not name every participant defensively; a vague group allegation makes it harder to prove who did what.
Measure only the harm added by the medication event
Compare the actual course with the likely course if the correct medicine had been prescribed, supplied and monitored. The underlying illness may itself have required consultation, tests, admission or time away from work. Identify what the medication event added: emergency treatment, antidote, dialysis, longer admission, organ injury, relapse caused by omission of the intended drug, rehabilitation or disability.
Keep receipts and invoices for the added care, travel and medicine. Employment or business loss needs records showing absence and reduced capacity. Future treatment requires a clinical plan and realistic costing. A short-lived reaction and a permanent injury are different claims even when the underlying error is identical.
Use records lawfully and protect confidentiality
The patient’s file should include the clinical and medication evidence needed to understand the event. The medical-records guide explains how to request records from each holder and preserve versions. Section 11 of the Health Act protects information concerning health and treatment subject to recognised statutory grounds. Share only what is necessary with authorised reviewers.
Where the alleged error arose from a wrong diagnosis rather than the physical dispensing transaction, the misdiagnosis and treatment guide provides a separate method for testing the diagnostic decision. Keep the two theories distinct so that a prescribing allegation does not become a catch-all criticism of the consultation.
Protect the civil timetable while complaints are pending
The starting rule in section 4(2) of the Limitation of Actions Act is that a tort action may not be brought after three years from accrual. For a qualifying personal-injury action, sections 27 and 28 contain a narrow procedure connected to decisive material facts that were outside the claimant’s knowledge. Late recognition of a drug reaction does not automatically bring a case within that procedure.
Record the prescription, dispensing, administration, first symptom, diagnosis and explanation dates. Obtain advice early. Reporting an adverse event, submitting a complaint to the Pharmacy and Poisons Board or another regulator, asking the facility to investigate, or negotiating with an insurer should not be assumed to suspend the civil clock.
Choose the route that matches the evidence
A provider or facility complaint may seek an explanation, corrected record, apology or safety change. A Board report may address pharmacy practice, product quality or pharmacovigilance within its mandate. A civil claim needs a proved duty, breach, causal injury and loss. One event may justify more than one route, but each process has a different decision and remedy.
Before making an allegation, create a five-column medication map: stage, source document, precise error, responsible person or system, and resulting injury. Add the relevant expert beside each disputed point. If the map shows a recognised adverse reaction despite reasonable prescribing, supply and monitoring, the evidence may support no negligence claim.
Request a Kenyan medication-error review with the original prescription, medicine and packaging, label photographs, receipt, consultation and dispensing records, hospital medication chart where relevant, symptom and dose timeline, adverse-event or complaint references, emergency treatment records, tests, expert material, expense evidence and the dates on which the error and possible injury were explained.
Frequently asked questions
Is a serious side effect proof that the medicine was wrongly prescribed in Kenya?
No. A serious adverse reaction can occur despite reasonable prescribing, dispensing and monitoring. A claim needs evidence of a defined error, such as the wrong patient, drug, dose, route, label or monitoring response, plus expert support that the error probably caused or added to the particular injury.
What should I preserve after receiving the wrong medicine or dose?
Keep the original prescription, product, package, label, receipt, remaining medicine and any corrected version. Photograph the patient name, drug, strength, directions, batch and expiry details, and save pharmacy messages and payment records. Also obtain the consultation, dispensing and administration records and the clinical record of the reaction.
Does reporting the error to the Pharmacy and Poisons Board stop the time for a civil claim?
It should not be assumed to do so. A Board report or complaint serves a regulatory and safety purpose, while a civil claim follows separate proof and limitation rules. The ordinary tort period under section 4(2) of the Limitation of Actions Act is three years from accrual, subject only to applicable legal rules and limited statutory exceptions.
