Pharmacy First has transformed the community pharmacist's role from supply to clinical assessment. You are no longer just recommending products — you are assessing presentations, excluding red flags, making clinical management decisions, and in some cases prescribing. The GPhC CRA tests this applied clinical decision-making. And the reality of daily community practice demands it.
This framework covers the structured approach to minor ailments — from initial assessment through management decision to referral trigger.
The WWHAM Framework and When to Upgrade It
Every pharmacy undergraduate learns WWHAM: Who is the patient? What are the symptoms? How long have they had them? Action already taken? Medications currently taking?
WWHAM is the baseline. It establishes context. But for clinical decision-making — the skill the exam tests and practice demands — you need structured escalation criteria layered on top.
The upgraded framework adds: Red flags (are any present that require immediate referral?), Exclusions (are there contraindications to OTC treatment — age, pregnancy, comorbidities, drug interactions?), Duration threshold (how long is too long for self-management before referral is warranted?), and Safety netting (what should the patient watch for, and when should they return or seek medical attention?).
The 20 Highest-Yield Minor Ailments
Headache
Key questions: onset pattern (sudden/thunderclap = red flag), associated symptoms (visual changes, neck stiffness, fever = red flag), frequency (chronic daily headache needs GP), medication overuse (analgesics >15 days/month). OTC: paracetamol or ibuprofen. Escalate: sudden severe onset, fever + neck stiffness, focal neurological signs, new headache in >50.
Cough
Key questions: duration (>3 weeks = chest X-ray referral per NICE NG12 2WW criteria if >45 + risk factors), productive vs dry, haemoptysis (red flag), weight loss, night sweats. OTC: simple linctus (limited evidence but patient-preferred), honey and lemon. Escalate: haemoptysis, >3 weeks, weight loss, smoker >45.
Sore Throat
Key questions: duration, severity, fever, unilateral swelling (peritonsillar abscess = red flag), difficulty swallowing fluids. Use Centor/FeverPAIN criteria to guide assessment. OTC: paracetamol, ibuprofen, medicated lozenges. Pharmacy First: pharmacist-prescribed antibiotics for strep throat meeting criteria. Escalate: drooling, stridor, trismus, unilateral tonsillar swelling.
Nasal Congestion / Rhinitis
Key questions: duration, seasonal pattern (allergic rhinitis), unilateral (polyps/tumour = red flag), post-nasal drip. OTC: saline irrigation, topical decongestant (max 7 days), intranasal corticosteroid for allergic rhinitis. Escalate: unilateral nasal obstruction, epistaxis, anosmia.
Hay Fever / Allergic Rhinitis
Key questions: seasonal vs perennial, eye symptoms, impact on sleep/work/school. OTC: non-sedating antihistamine (cetirizine, loratadine), intranasal corticosteroid (beclometasone, fluticasone), sodium cromoglicate eye drops. Escalate: symptoms not controlled by OTC after 2-4 weeks.
Earache
Key questions: age (children <2 = lower threshold for referral), discharge (otorrhoea), hearing loss, recent URTI, swimming (otitis externa). OTC: paracetamol/ibuprofen for pain. Pharmacy First: ear drops for otitis externa in some pathways. Escalate: mastoid tenderness, facial nerve palsy, vertigo, persistent discharge.
Conjunctivitis
Key questions: unilateral vs bilateral, discharge character (purulent = bacterial, watery = viral/allergic), pain (red flag — iritis, keratitis, glaucoma), visual disturbance, contact lens wearer. OTC: chloramphenicol 0.5% eye drops (P medicine — pharmacist supply). Escalate: pain, visual disturbance, photophobia, contact lens wearer with red eye, neonatal conjunctivitis.
Oral Thrush
Key questions: immunocompromised? (HIV, inhaled corticosteroid use — check inhaler technique), denture wearer, recurrent episodes. OTC: miconazole oral gel. Escalate: dysphagia (oesophageal candidiasis), recurrent without identifiable cause, immunocompromised patient.
Cold Sores
Key questions: frequency, location (always perioral — intraoral = different pathology), immunocompromised. OTC: aciclovir 5% cream (most effective if applied at prodrome stage). Escalate: periorbital involvement (herpes keratitis risk), immunocompromised, severe/frequent recurrence.
Indigestion / Heartburn
Key questions: duration, frequency, alarm symptoms (dysphagia, weight loss, haematemesis, persistent vomiting = 2WW referral per NICE NG12). OTC: antacids (rapid relief), alginates (Gaviscon), H2RA (ranitidine alternatives — famotidine), short-course PPI (omeprazole OTC 10mg). Escalate: any alarm symptom, >55 with new dyspepsia (NICE NG12 2WW criteria), NSAID use, persistent despite OTC.
Constipation
Key questions: duration, diet and fluid intake, new onset in >50 (red flag — possible colorectal pathology), alternating with diarrhoea (IBS vs colorectal cancer), medications causing constipation (opioids, anticholinergics). OTC: bulk-forming (ispaghula husk first-line), osmotic (macrogol), stimulant (senna, bisacodyl — short-term). Escalate: new onset >50, blood in stool, weight loss, alternating bowel habit.
Diarrhoea
Key questions: duration (>7 days = investigate), blood/mucus (red flag), recent travel (tropical infection), recent antibiotics (C. diff risk), dehydration signs. OTC: oral rehydration salts (first-line), loperamide (short-term symptomatic relief in adults). Escalate: bloody diarrhoea, severe dehydration, recent antibiotics + fever, immunocompromised.
Haemorrhoids
Key questions: bleeding pattern (bright red on paper/toilet = typically haemorrhoidal), prolapse, pain, duration, age >50 with new rectal bleeding (2WW pathway). OTC: topical preparations (anusol, hydrocortisone-containing — short course only), bulk-forming laxative. Escalate: persistent bleeding, change in bowel habit, >50 with new symptoms.
Uncomplicated UTI (Cystitis)
Key questions: age (16-64 women), pregnant (red flag — always refer), fever/loin pain (pyelonephritis = red flag), recurrent, male (always refer). Pharmacy First: supply trimethoprim or nitrofurantoin for uncomplicated lower UTI in women 16-64 (check local pathway). Escalate: pregnancy, male, fever, loin pain, recurrent (>3/year).
Athlete's Foot
OTC: topical antifungal (clotrimazole, terbinafine cream). Escalate: extensive involvement, immunocompromised, suspected secondary bacterial infection.

Eczema (Mild)
OTC: emollients (first-line — generous, frequent application), mild topical corticosteroid (hydrocortisone 1% — 7-day course max for face). Escalate: infected eczema, severe flare, unresponsive to emollients and mild steroid.
Insect Bites
OTC: topical antihistamine or hydrocortisone 1% for localised reaction, oral antihistamine for widespread. Escalate: signs of systemic allergic reaction, signs of cellulitis (spreading erythema, fever).
Musculoskeletal Pain
OTC: paracetamol, topical NSAIDs (ibuprofen gel, diclofenac gel), oral ibuprofen. Check for contraindications (renal, cardiac, GI history). Escalate: traumatic injury with deformity (fracture), inability to weight-bear, hot swollen joint (septic arthritis/gout).
Pharmacy First: The Expanded Clinical Service
Pharmacy First allows pharmacists to supply prescription-only medicines for specific conditions without a GP prescription. Current conditions include uncomplicated UTI (women 16-64), impetigo, infected insect bites, shingles (within 72 hours of rash onset), acute sore throat, acute sinusitis, and acute otitis media.
For each Pharmacy First condition, the pharmacist conducts a structured clinical assessment, applies the clinical pathway criteria (each condition has specific inclusion and exclusion criteria), prescribes the appropriate POM where criteria are met, documents the consultation (including clinical findings, decision rationale, and safety netting advice), and refers to the GP if the patient does not meet inclusion criteria or if red flags are identified.
The documentation requirement is critical. Pharmacy First consultations are clinical encounters that generate a prescribing record. They must be documented to the same standard as a GP consultation — including the clinical assessment findings that justified the prescribing decision, the medication supplied, the dose and duration, and the safety netting advice provided. Inadequate documentation creates governance risk and undermines the credibility of the service.
What Pharmacy First changes for the CRA: The GPhC exam now tests the clinical assessment and prescribing decision-making skills that Pharmacy First demands — not just OTC product knowledge. Questions may present a patient meeting Pharmacy First criteria and ask whether the pharmacist should supply the POM, refer to the GP, or recommend self-care. This requires applied clinical judgment, not product recall.
Red Flags: The Systematic Approach
Every minor ailment consultation must screen for red flags — symptoms or features that indicate a potentially serious underlying condition requiring medical referral. The challenge is not knowing what red flags exist (most pharmacists learn these during MPharm training) but systematically screening for them during a busy counter consultation where the default cognitive mode is "recommend a product and move on."
A systematic approach uses the acronym REDS: Rapid onset (sudden, severe symptoms suggesting acute pathology), Extremes of age (very young or elderly patients have different risk profiles and lower thresholds for referral), Duration (symptoms persisting beyond the expected self-limiting timeframe), and Systemic features (fever, weight loss, night sweats, malaise suggesting an underlying systemic process rather than a localised minor ailment).
Rapid onset: A headache that comes on suddenly and severely ("thunderclap") is a red flag for subarachnoid haemorrhage — regardless of how the patient describes it. A sore throat with drooling and stridor is a red flag for epiglottitis. Sudden unilateral leg swelling is a DVT until proven otherwise. The common thread: suddenness and severity suggest an acute process that OTC management cannot address.
Extremes of age: Neonatal conjunctivitis requires urgent ophthalmology referral (gonococcal ophthalmia risk). Earache in children under 2 has a lower threshold for medical review. New-onset headache in patients over 50 should trigger consideration of temporal arteritis. New-onset constipation or rectal bleeding in patients over 50 requires investigation for colorectal pathology per NICE NG12 2-week-wait criteria.
Duration: A cough lasting over 3 weeks requires chest X-ray referral in patients over 45 with risk factors (NICE NG12). Diarrhoea lasting over 7 days requires investigation. Hoarseness lasting over 3 weeks requires ENT referral. The duration thresholds are specific to each condition and must be known — they are heavily tested in the CRA.
Systemic features: Weight loss, night sweats, persistent fever, and unexplained fatigue suggest underlying pathology (malignancy, infection, autoimmune disease) that a minor ailment consultation should not attempt to manage. Any minor ailment accompanied by systemic features should be referred for medical evaluation.
Age-Specific Considerations
Paediatric patients. Many OTC medicines are contraindicated or require dose adjustment in children. Aspirin is contraindicated in under-16s (Reye's syndrome risk). Codeine is contraindicated in under-12s and in under-18s post-tonsillectomy/adenoidectomy. Loperamide is not recommended in under-12s. Ibuprofen requires weight-based dosing in children. The BNFc (not BNF) should be referenced for all paediatric OTC recommendations — and the pharmacist must confirm the child's age and weight before making a recommendation.
The safeguarding dimension is also relevant: a child presenting repeatedly with minor injuries, a child whose symptoms do not match the parent's account, or a child who appears neglected or distressed should trigger safeguarding awareness — not necessarily a referral, but a professional judgment about whether the situation raises concern.
Elderly patients. Polypharmacy interactions are common. An elderly patient requesting ibuprofen may already be on an ACEi plus a diuretic — creating the "triple whammy" nephrotoxicity risk. Anticholinergic OTC medicines (older antihistamines like chlorphenamine, hyoscine for travel sickness) increase anticholinergic burden in patients already on anticholinergic prescriptions. Falls risk is increased by sedating OTC medicines. The medication history check (the "M" in WWHAM) is especially important in elderly patients.
Pregnant and breastfeeding patients. Most OTC medicines require pregnancy and breastfeeding safety checks. Ibuprofen is avoided after 28 weeks' gestation. Aspirin has specific gestational considerations. Many herbal and complementary remedies are not safety-tested in pregnancy. Ask iatroX can verify pregnancy safety quickly — "Is chlorphenamine safe in the first trimester?" — with BNF-cited answers.
Worked Clinical Vignettes
Vignette 1: A 28-year-old woman presents with dysuria and urinary frequency for 2 days. No fever, no loin pain, not pregnant, no previous UTI in the last 3 months, no renal history. She is not taking any regular medication.
Decision: This meets Pharmacy First criteria for uncomplicated UTI in a woman aged 16-64. Supply trimethoprim 200mg BD for 3 days (or nitrofurantoin 100mg MR BD for 3 days if local pathway prefers). Document the consultation. Safety net: return if symptoms worsen, develop fever or loin pain, or do not improve within 48 hours.
Vignette 2: A 55-year-old man presents requesting "something for his indigestion" that has been present for 3 weeks. He has lost half a stone in weight without trying. He is not taking NSAIDs.
Decision: Do NOT recommend an OTC antacid or PPI. This is a 2-week-wait referral under NICE NG12 — new-onset dyspepsia in a patient over 55 with weight loss meets the criteria for urgent investigation for upper GI malignancy. Refer to GP urgently. Document your reasoning.
Vignette 3: A mother brings her 3-year-old with a cough that has been present for 5 days. The child is eating and drinking normally, has no fever, and is playful in the pharmacy. The cough is worse at night.
Decision: This is likely a viral upper respiratory tract infection with post-nasal drip. Simple honey-based preparation for nighttime cough (honey is evidence-supported for nocturnal cough in children over 1 year). No OTC cough suppressants for under-6s. Safety net: return if fever develops, breathing becomes difficult, child stops eating/drinking, or cough persists beyond 3 weeks.
Vignette 4: A 42-year-old woman presents with a red, painful eye. She wears daily disposable contact lenses. Vision is unaffected.
Decision: Do NOT supply chloramphenicol. Contact lens wearer with a red eye requires same-day medical or optometry assessment — the differential includes microbial keratitis, which is sight-threatening. Refer urgently. Advise her to remove the contact lens and not reinsert it until assessed.
Vignette 5: A 70-year-old man requests ibuprofen for knee pain. He takes ramipril 10mg, amlodipine 5mg, and furosemide 40mg daily. He has CKD stage 3a (eGFR 52).
Decision: Do NOT supply ibuprofen. The combination of ACEi (ramipril) + diuretic (furosemide) + NSAID (ibuprofen) is the "triple whammy" — significantly increased risk of acute kidney injury in a patient who already has CKD. Recommend paracetamol as first-line analgesic. If pain is not controlled, recommend topical ibuprofen gel (minimal systemic absorption) or advise GP review for alternative analgesia. Document the interaction risk you identified and the alternative recommended.
Interaction Checking During Counter Consultations
The medication history check — the "M" in WWHAM — is where counter consultations most frequently identify serious potential harm. A patient requesting an OTC product may be taking prescribed medicines that interact with it, and the pharmacist is often the only healthcare professional in the pathway who will catch this.
The highest-risk OTC interactions to be aware of include: NSAIDs (ibuprofen, aspirin) with anticoagulants (warfarin, DOACs — increased bleeding risk), NSAIDs with ACEi/ARB plus diuretics (the triple whammy), antacids and PPIs with levothyroxine (reduced absorption — separate by 4 hours), St John's Wort with combined oral contraceptives, anticoagulants, SSRIs, and many other drugs (potent CYP3A4 inducer), antihistamines (sedating — chlorphenamine, promethazine) with other CNS depressants and in patients at falls risk, and decongestants (pseudoephedrine, phenylephrine) in patients with uncontrolled hypertension or those taking MAOIs.
The practical challenge is that patients do not always volunteer their medication list when requesting an OTC product. A proactive "Are you taking any regular prescribed medicines?" must be a default question for every recommendation — not just when the pharmacist suspects a potential interaction. Building this habit is what the WWHAM framework enforces, and what the CRA tests through clinical scenarios where the medication history reveals a hidden interaction risk.
The Counter Consultation Structure for the CRA
The GPhC exam tests minor ailments decision-making through clinical scenarios that present a patient with specific symptoms, a medication history, and sometimes additional contextual information (age, pregnancy status, comorbidities). The correct answer requires the candidate to integrate all of this information — not just identify the symptom and recommend a product.
The structure the exam rewards follows this sequence: identify the presenting complaint, ask clarifying questions (WWHAM plus red flag screening), check for contraindications and interactions against the medication history, select the appropriate management (OTC product, Pharmacy First POM, self-care advice, or referral), provide counselling points, and safety net with clear return criteria.
Candidates who jump from "symptom" to "product" without working through the intermediate steps — interaction checking, contraindication screening, red flag assessment — lose marks on questions where the scenario deliberately includes a hidden contraindication or interaction. The CRA rewards systematic clinical reasoning, not product knowledge.
Practise this systematic approach using the iatroX GPhC Q-bank — the adaptive engine will identify which steps in your clinical reasoning are weakest and concentrate practice on those specific decision points.
Using iatroX for Minor Ailments Decision Support
Ask iatroX answers the clinical queries that arise during counter consultations — "Is trimethoprim safe in a patient taking methotrexate?" / "What is the Pharmacy First pathway for acute otitis media?" / "At what age should new-onset rectal bleeding trigger a 2WW referral?" / "Can I supply chloramphenicol to a contact lens wearer?" — with NICE/BNF-grounded answers. During a busy dispensing day, the ability to verify a clinical decision in 10 seconds rather than consulting the BNF and searching CKS manually is the difference between confident, efficient practice and uncertainty-driven delays.
iatroX Calculators provides FeverPAIN and Centor scores for sore throat assessment — directly relevant to the Pharmacy First acute sore throat pathway, where the clinical score determines whether antibiotic supply is appropriate.
The GPhC Q-bank includes minor ailments scenarios in the adaptive question bank — practising the applied decision-making that the CRA tests. The adaptive engine concentrates practice on the minor ailment areas where your decision-making is weakest — ensuring you are confident across all 20 high-yield conditions, not just the ones you see most frequently in your dispensary.
Building Minor Ailments Competence: For Trainees and Qualified Pharmacists
For foundation trainees preparing for the CRA, minor ailments competence is tested through Part 2 SBA and EMQ scenarios. The exam presents a patient with symptoms, a medication history, and contextual information — and expects you to select the appropriate management from the options provided. Practising these scenarios under timed conditions on the iatroX GPhC Q-bank builds the systematic reasoning that distinguishes a pass from a fail.
For qualified pharmacists already working in community practice, minor ailments competence is not static — it evolves with Pharmacy First expansions, NICE guideline updates, and MHRA safety alerts. A new safety alert restricting an OTC product, a new Pharmacy First condition added to the service, or a revised NICE referral threshold all change the correct management for a given scenario. Using Ask iatroX as your daily reference tool ensures you are always applying current guidance — not the guidance you learned during your MPharm programme, which may be several years out of date.
The strongest community pharmacists treat every counter consultation as a clinical encounter — applying the same systematic reasoning, the same red flag screening, and the same interaction checking that the CRA tests. The weakest treat it as a product recommendation exercise. The difference is clinical governance, patient safety, and professional satisfaction — and it is the difference between a pharmacist who is practising clinically and one who is dispensing with occasional customer interaction.
