Allergic Rhinitis
Red Flags — features suggesting non-allergic rhinitis, polyps, or malignancy
| Red flag | Why dangerous | Action |
|---|---|---|
| Unilateral nasal obstruction or unilateral nasal mass | Unilateral nasal polyp or mass is malignancy until proven otherwise. Sinonasal tumours (squamous cell carcinoma, adenocarcinoma, olfactory neuroblastoma) present with unilateral obstruction, epistaxis, facial swelling. Allergic polyps are bilateral. Any unilateral nasal mass requires urgent ENT referral and CT/MRI. | Urgent ENT referral; CT sinuses; 2-week wait pathway if malignancy suspected |
| Purulent or bloodstained nasal discharge | Clear watery discharge = AR. Purulent (yellow/green) = bacterial sinusitis or foreign body (especially children). Bloodstained = local trauma, polyp, malignancy, Wegener's granulomatosis. Unilateral bloodstained discharge with facial pain: ENT urgently. | ENT referral; CT sinuses; consider ANCA if vasculitis suspected (Wegener's) |
| Anosmia — sudden or progressive loss of smell | Mild hyposmia is common in AR (from obstruction). Sudden anosmia with no preceding AR: viral (post-COVID; post-viral); zinc deficiency; intracranial cause (olfactory groove meningioma). Progressive anosmia with nasal polyps: chronic rhinosinusitis with nasal polyps (CRSwNP). Anosmia severely affects QoL and safety (cannot smell gas, smoke, food spoilage). | ENT referral; CT sinuses; consider MRI if intracranial cause suspected; safety counselling (gas detector) |
| Severe uncontrolled asthma with AR | Poorly controlled AR is one of the most common and underrecognised causes of difficult-to-control asthma. United airways: treating AR improves asthma control in the majority of cases. A patient with severe asthma who also has AR should have both conditions assessed and treated simultaneously. | Asthma review; FeNO; spirometry; treat AR simultaneously; consider immunotherapy if both conditions are moderate-severe |
| Nasal polyps with aspirin/NSAID intolerance | Samter's triad (aspirin-exacerbated respiratory disease — AERD): nasal polyps + asthma + aspirin/NSAID hypersensitivity. NSAIDs can precipitate severe life-threatening bronchospasm in these patients. Must identify before prescribing any NSAID or aspirin. Prevalence of AERD in patients with nasal polyps and asthma: approximately 10–15%. | Avoid aspirin and NSAIDs; document allergy prominently; ENT; dupilumab biologic consideration; NSAID desensitisation protocol (specialist) |
| Nasal symptoms in child under 2 years | AR is rare under 2 years. Persistent unilateral nasal obstruction in an infant: foreign body (beads, food); choanal atresia; nasal dermoid. Bilateral obstruction in a neonate: obligate nasal breathers — choanal atresia is a medical emergency. Allergic rhinitis is an overdiagnosis in very young children. | ENT review; exclude foreign body; examine carefully for structural cause; do not diagnose AR <2 without specialist input |
Safeguarding Considerations in Allergic Rhinitis
🚗 Driving and Sedating Antihistamines
- Sedating antihistamines (chlorphenamine, promethazine): significantly impair driving ability — equivalent to moderate alcohol intoxication; 30% increased accident risk in studies
- DVLA: patients must not drive if impaired; they may be prosecuted for driving under the influence of a sedating antihistamine
- Non-sedating antihistamines (cetirizine, loratadine, fexofenadine) do not impair driving at standard doses; however at high doses or in susceptible individuals, some sedation occurs — counsel patients to assess their own response before driving
- Chlorphenamine (Piriton): still frequently prescribed for acute allergy — if prescribed, must warn about driving; not appropriate as regular hay fever treatment for drivers
🤰 Pregnancy and Breastfeeding
- AR is common in pregnancy; untreated AR impairs sleep, causes mouth breathing, and worsens QoL; treatment is justified
- Safest INCS in pregnancy: budesonide (most safety data); fluticasone also commonly used; INCS systemic absorption negligible at standard intranasal doses
- Antihistamine in pregnancy: cetirizine and loratadine are most commonly used and generally considered safe based on available data; avoid chlorphenamine (limited safety data; sedation)
- Decongestants (oxymetazoline, xylometazoline): avoid in first trimester; systemic decongestants (pseudoephedrine): avoid in pregnancy
🧒 Children and Sedating Antihistamines
- Sedating antihistamines paradoxically cause excitation in some children — avoid in young children; non-sedating preferred
- AR in children: significantly impairs academic performance (concentration, sleep); treat adequately; INCS safe in children from age 6 (mometasone) or 4 years (fluticasone furoate — Avamys)
- School performance in exam periods: ensure treatment is optimised before exams; hay fever season overlaps with GCSE and A-Level periods — a significant public health concern
🦺 Occupational Rhinitis
- Occupational allergens causing AR: flour dust (bakers); latex (healthcare workers); isocyanates (painters, sprayists); wood dust (carpenters); animal dander (veterinarians, laboratory workers); grain dust (farmers)
- Occupational rhinitis often precedes occupational asthma — early identification and allergen removal is critical
- Reporting: health and safety obligations for employers; RIDDOR reporting if occupational; referral to specialist occupational health
🏫 Occupational Impact for a Teacher
A teacher's core professional tools are voice projection, sustained concentration, and emotional regulation. Nasal obstruction affects all three: nasal congestion → mouth breathing → voice fatigue and changed vocal quality; fatigue → reduced concentration; sneezing and nasal discharge in a classroom setting → embarrassment; eye symptoms → reading difficulties. Emily's symptoms are professionally significant and justify treatment escalation.
"I want to understand how much this is affecting your teaching. Nasal obstruction causes real cognitive effects — it is not just discomfort. The research shows it affects concentration similarly to having a moderate cold every day. That is important to acknowledge, and it is a good reason to get the treatment right."💊 Steroid Anxiety — a Treatment Barrier
Emily's concern about steroid sprays is the single biggest barrier to her receiving optimal treatment. It is a common and understandable misconception. The clinical fact: intranasal corticosteroids at standard doses (fluticasone 200mcg/day) have negligible systemic absorption — bio-availability is less than 1% for fluticasone propionate. The skin-thinning associated with steroids requires systemic levels orders of magnitude higher than those achieved with a nasal spray. Addressing this clearly is the central therapeutic task of this consultation.
"I understand the worry about steroids — it is really common. The steroid in a nasal spray is completely different from taking steroid tablets. The amount that gets into your system from a nasal spray is less than 1% — which is why it does not cause the side effects you are thinking of. What it does do is treat the inflammation in your nose directly, which is what is causing the congestion."🐱 The Cat — a Sensitive Topic
Advising Emily that the cat is contributing to her symptoms puts her in a difficult position — it is her boyfriend's cat and involves a complex set of personal and relational factors. Dismissing the cat question ("just take antihistamines and you'll be fine") is clinically inadequate. Demanding she gets rid of the cat is socially tone-deaf. The correct approach: be honest about the cat's role, acknowledge the difficulty, offer realistic partial measures (cat out of bedroom; HEPA filter), and frame immunotherapy as the long-term solution that allows coexistence with pets in some cases.
"I want to be honest with you about the cat — it is almost certainly contributing significantly. I am not going to tell you to get rid of it, because I know that is complicated. What I would say is: keeping the cat out of the bedroom will reduce your overnight exposure significantly. A good air purifier with a HEPA filter also helps. And there are treatments — called immunotherapy — that can actually desensitise your immune system over time. That might be worth discussing if things don't improve with the spray."😴 Sleep Disruption and Fatigue
Nocturnal nasal obstruction — Emily's predominant complaint — is the most impactful symptom for QoL in AR. It causes fragmented sleep, daytime fatigue, morning headache, and cognitive impairment. This is also the symptom that antihistamines (her current treatment) address least effectively. INCS is the most effective drug for obstruction. Making the connection between her night-time blockage, her daytime fatigue, and the choice of treatment (INCS not antihistamine) is the central clinical education in this consultation.
"The blocked nose at night that is keeping you awake — that is actually the symptom that antihistamines are worst at treating, because it is not driven by histamine, it is driven by inflammation. The nasal spray directly targets that inflammation. If you can use it consistently every morning, most people notice a significant improvement in the night-time congestion within 2 weeks."🔬 "Do I Need Allergy Tests?"
Emily may ask about allergy testing. The clinical reality: in primary care, the diagnosis of AR is clinical (history and examination) and does not require allergy testing in most cases. Allergy testing (skin prick test or specific IgE) is indicated when: the allergen is uncertain and identification would change management; allergen immunotherapy is being considered; the patient has severe or atypical symptoms; occupational rhinitis is suspected. Routine allergy testing to confirm what is already clinically clear is not evidence-based.
"Allergy tests are not needed for most people with hay fever — the history tells us what we need to know. Where testing becomes useful is if we are considering a treatment called immunotherapy — which actually changes how your immune system responds to the allergen. If things don't improve on the spray, that's when we would consider testing and refer you to a specialist."🏃 Exercise and Activity
Emily reports exercise-induced wheeze in spring — this needs formal asthma assessment. Beyond this, AR affects exercise tolerance directly: nasal obstruction forces mouth breathing, which reduces warming and filtering of air, increasing bronchial irritation; dehydration of bronchial mucosa during mouth breathing worsens exercise-induced bronchoconstriction. Optimal AR treatment improves exercise tolerance in both AR-only patients and those with comorbid asthma.
"The wheeze you get when exercising in spring is something I want to assess properly — it could be that your hay fever is affecting your airways more than just the nose. I'd like to do a breathing test called spirometry to check. Treating the hay fever well often improves exercise-induced symptoms too."- Not addressing the steroid concern — Emily will not use INCS unless this misconception is corrected
- Not screening for asthma — united airways is a core component of AR management
- Prescribing or recommending chlorphenamine (sedating) — Emily is a professional driver of public safety; non-sedating is mandatory
- Telling Emily to get rid of the cat without empathy or realistic alternatives
- Not asking about current treatment pattern (PRN vs regular)
999 / A&E
Immediate action- Anaphylaxis — allergen exposure with systemic reactionUrticaria + wheeze + hypotension → 999; IM adrenaline 0.5mg; antihistamine + hydrocortisone after stabilisation
- Severe acute asthma triggered by allergenSpO2 <94%; PEFR <50% predicted; unable to complete sentences → 999; nebulised salbutamol; systemic steroid
- Angioedema with airway compromiseLip/tongue/throat swelling + stridor or difficulty swallowing → 999; IM adrenaline; airway priority
Within 2–6 Weeks
ENT / Allergy / Respiratory- Unilateral nasal mass or obstructionENT urgently (2-week wait if malignancy suspected); CT sinuses
- Severe AR + asthma not controlled on pharmacotherapyAllergy specialist; immunotherapy assessment; consider dupilumab for CRSwNP
- Rhinitis medicamentosa — decongestant dependencyStop decongestant; start INCS; counsel on withdrawal; primary care manages
GP Management
Primary care first-line- Seasonal AR — inadequate antihistamine responseAdd INCS; regular antihistamine; allergen avoidance; review in 6–8 weeks
- Perennial AR — new allergen identifiedINCS + antihistamine; allergen avoidance counselling; asthma screen
- AR + possible asthma — united airwaysSpirometry + reversibility; FeNO if available; diagnose both; treat both
- Not identifying that Emily's symptoms are moderate-severe (sleep + work affected) — determines treatment escalation
- Not triaging the united airways question (wheeze) as requiring formal assessment
- Not examining the nasal mucosa — misses polyps; polyps change management significantly
- Routinely ordering specific IgE before treating — not required for first-line AR diagnosis and management; delays treatment unnecessarily
- Not arranging spirometry when respiratory symptoms are reported
"Hay fever — or more broadly, allergic rhinitis — is your immune system overreacting to something harmless in the environment, like grass pollen or cat dander. The first time your body encountered these allergens, it made antibodies. Every subsequent exposure causes those antibodies to trigger mast cells in your nasal lining to release chemicals — histamine being the most famous one — and this causes all your symptoms: the sneezing, itching, runny nose, and swollen lining. The swelling that blocks your nose at night is driven mainly by inflammation, not just histamine — which is why antihistamines alone don't fully fix the blockage. The steroid spray works directly on the inflammation in the nasal lining. Used every day, it reduces the swelling that is blocking your nose at night and causing the fatigue. The reason your symptoms have become year-round is almost certainly the cat — cat dander is an extremely powerful allergen and has been added on top of your existing grass pollen allergy."
"I've heard steroid sprays thin your skin and cause facial changes."
"That is a very understandable concern — and you are right that steroid tablets and skin creams can cause those effects at certain doses. The nasal spray is completely different. The amount of steroid that gets absorbed into your bloodstream from a nasal spray is less than 1% — compared with a steroid tablet, which is 100 times more. At the doses used in a nasal spray, there is no meaningful systemic absorption, and no risk of skin thinning or facial changes. The spray stays in your nose where it's needed."
"Why isn't my antihistamine working well enough?"
"Antihistamines are very good for sneezing, itching, and runny nose — because those are driven by histamine. But the blocked nose, especially at night, is mainly caused by inflammation and swelling of the nasal lining — which is not a histamine effect. The steroid spray works on that inflammation directly. Using both together gives you the best of both worlds: the spray for the blockage, the antihistamine for the sneezing and itch."
Non-Allergic Rhinitis
No IgE mechanism; triggered by irritants (smoke, scent, cold air); no seasonal pattern; negative IgE; INCS still helps; antihistamines less effective.
Chronic Rhinosinusitis
Persistent facial pressure + purulent discharge + anosmia; CT sinuses; prolonged INCS + nasal irrigation; ENT if refractory.
Rhinitis Medicamentosa
Rebound from nasal decongestant overuse; INCS during withdrawal; stop decongestant; max 7 days rule.
Unilateral Nasal Mass
Malignancy until proven otherwise — urgent ENT; CT sinuses; 2-week wait.
Nasal Polyps + Asthma + NSAID Sensitivity
Samter's triad — avoid aspirin/NSAIDs; ENT; dupilumab.
Undiagnosed Asthma
United airways — spirometry; FeNO; diagnose and treat simultaneously.
- Not explaining why INCS is more effective than antihistamine for obstruction — Emily needs this explanation to understand why treatment is being changed
- Not mentioning immunotherapy as a future option — it is the only disease-modifying treatment and is particularly relevant for Emily's cat allergy
Address the steroid misconception directly
Emily's concern about INCS causing skin thinning is the single most important barrier to effective treatment. It must be addressed with a specific mechanistic explanation, not dismissed with "they're fine." The explanation: systemic steroid effects require blood levels orders of magnitude higher than those achieved from nasal absorption of INCS at standard doses.
"The nasal spray contains a steroid, but the amount absorbed into your bloodstream is less than 1% — compared with a steroid tablet, it's tiny. The skin thinning you've heard about happens with steroid tablets or with skin creams applied repeatedly in the same place. The nasal spray doesn't reach those concentrations in your blood or skin."Explain why the spray beats the antihistamine for her main symptom
Emily's dominant symptom is nocturnal nasal obstruction. Antihistamines address sneezing and itch (histamine-mediated). Obstruction is driven by vascular engorgement and mucosal inflammation — INCS addresses both. Once Emily understands why the spray is the right treatment for her specific dominant symptom, adherence becomes clinically motivated, not instruction-compliance.
"The blocked nose at night is driven mainly by inflammation and swelling in your nasal lining — that's an anti-inflammatory spray's job, not an antihistamine's. The antihistamine is still useful for the sneezing and the itch. But to fix what's keeping you awake, the spray is the right tool."The cat — honest, empathetic, practical
Be honest that the cat is contributing significantly. Offer realistic partial measures without demanding an impossible choice. Frame immunotherapy as the long-term solution that makes continued cat coexistence more sustainable. Do not catastrophise, but do not pretend the cat is irrelevant.
"I'm not going to tell you to get rid of the cat — I know that's complicated. But I do want to be honest: while the cat is there, the medication is working against an ongoing allergen source. The most practical immediate steps are: cat out of the bedroom, HEPA air filter, wash hands after touching. And if things don't settle with the spray, immunotherapy might actually be the best answer for you."Check daily pollen count (Met Office app; BBC Weather). On high-pollen days: keep windows closed (especially morning); dry washing indoors; shower and change clothes after outdoor activity; wear wraparound sunglasses (reduces ocular allergen load by ~50%); apply petroleum jelly (Vaseline) inside nostrils (traps pollen particles before mucosal contact). Avoid mowing grass or walking through long grass during peak season.
Start INCS 2 weeks before pollen season onset (mid-April for tree; end of May for grass) — allows anti-inflammatory effect to be established before peak exposure. Cetirizine: start regular from first symptom or prophylactically at season start.
Bedroom exclusion: cat never in bedroom — cat-free sleeping environment is the single most impactful practical measure. Fel d 1 (major cat allergen) is carried on ultrafine particles that penetrate bedding deeply and persist for months. HEPA air purifier in bedroom: reduces airborne cat allergen by up to 60%. Weekly hoovering with HEPA vacuum; microfibre cloths. Wash hands after cat contact before touching face. Wipe cat down with damp cloth to reduce surface allergen shedding.
If symptoms remain poorly controlled despite pharmacotherapy and partial avoidance: cat-specific allergen immunotherapy — now available (specialist referral); offers desensitisation over 3 years. Not a first-line option but a realistic long-term solution for patients who cannot or will not remove the pet.
Mite-proof mattress, duvet, and pillow covers (reduces HDM allergen exposure during sleep — most significant 8 hours of allergen contact). Wash bedding weekly at ≥60°C (kills mites). Replace pillows every 1–2 years. Remove carpets from bedroom if possible; hard floors. Reduce humidity (target <50%): dehumidifier; adequate ventilation. Avoid soft toys in bed or wash weekly at 60°C. HEPA vacuum cleaner. Air purifier with HEPA filter.
HDM avoidance measures individually have modest evidence; combined multi-intervention approach is more effective. Mite-proof covers + weekly hot washing is the most evidence-based single combination measure. Total allergen elimination from a home environment is not realistic; reduction is the achievable goal.
Sodium cromoglicate 2% eye drops: first-line for allergic conjunctivitis; mast cell stabiliser; OTC available; must be used regularly (4 times/day); prophylactic use from season start. Olopatadine 0.1% (Opatanol): antihistamine + mast cell stabiliser; OD or BD; faster onset than cromoglicate; prescription required. Ketotifen (Zaditen): OTC; dual action. Avoid: topical decongestant eye drops (naphazoline, xylometazoline) — rebound hyperaemia with prolonged use.
Wraparound sunglasses outdoors (reduces airborne allergen reaching conjunctiva). Cold compresses for acute relief. Remove contact lenses during symptomatic periods — daily disposables preferred during pollen season.
Nasal saline irrigation (NeilMed Sinus Rinse; Neti pot; saline nasal spray) has good evidence as an adjunct to pharmacotherapy for both AR and chronic rhinosinusitis. Mechanism: flushes allergens and mucus from nasal cavity; reduces allergen dwell time on nasal mucosa; improves mucociliary clearance. Isotonic saline: symptom relief; hypertonic saline: more effective for rhinorrhoea reduction. Safe in pregnancy and children from 6 months.
Once or twice daily (morning and evening during symptomatic periods); use before INCS if combined — irrigation clears the mucosa allowing better INCS deposition. Technique: head tilted forward; solution entered one nostril, exits other. Sterile water or specific saline sachets — never tap water alone (infection risk).
GCSE and A-Level exam season (May–June) coincides with grass pollen peak. Emily's students and her own performance are both at risk. Ensure INCS is started by end of May (2 weeks before peak). Non-sedating antihistamine taken at night or morning (cetirizine is effective for 24 hours; loratadine similarly). Classroom: keep windows closed during high-pollen mornings; air conditioning (recirculating, not fresh air inlet) where available. Emily: voice projection may be affected by nasal obstruction — INCS significantly improves this.
Emily is a professional: her job requires alertness and clear cognition. Cetirizine and loratadine do not impair driving or cognition at standard doses in most people. Fexofenadine has the least sedating profile. Avoid chlorphenamine entirely for regular use — significant cognitive impairment even at standard doses.
INCS: fluticasone propionate (Flixonase) or mometasone (Nasonex) — most effective class for AR
- Use every day (not PRN) — anti-inflammatory effect requires consistent use; full effect in 1–2 weeks
- Technique: slightly forward head tilt; spray directed towards lateral wall (away from septum); sniff gently after administration; do not blow nose immediately
- Systemic absorption <1% (fluticasone propionate); no meaningful systemic steroid effects at standard doses
- Non-sedating antihistamine alongside: cetirizine 10mg OD or loratadine 10mg OD — addresses sneezing and itch that INCS addresses less effectively acutely
- Eye drops if ocular symptoms: sodium cromoglicate 2% QDS or olopatadine 0.1% BD
- Check INCS technique first — the commonest reason for failure is spraying towards the septum or using PRN rather than regularly
- Intranasal antihistamine (azelastine): fast onset (15 minutes); useful for breakthrough symptoms; add to INCS if still inadequate
- Dymista (azelastine + fluticasone combination spray): superior to either component alone; convenient; reduces tablet burden; good option when Step 1 is partially effective
- Leukotriene receptor antagonist (montelukast 10mg OD): modest benefit for both AR and asthma; MHRA black box neuropsychiatric warning — depression, anxiety, suicidal ideation; warn patient; PHQ-9; prefer Dymista before montelukast where possible
- Allergen immunotherapy (AIT): the only disease-modifying treatment for AR — changes immune response, not just symptoms; 3-year course; persists after stopping
- SLIT (sublingual) — grass pollen: Grazax (Timothy grass pollen tablet) — once daily sublingual; NICE-approved for severe SAR; taken for 3 years; start 4 months before pollen season. Also SCIT (subcutaneous) for multiple allergens
- SCIT (subcutaneous immunotherapy): hospital-administered; weekly then monthly injections; anaphylaxis risk — 30-minute post-dose observation; more effective than SLIT for multiple allergens
- Dupilumab (Dupixent): biologic (anti-IL-4/IL-13); NICE-approved for CRSwNP (chronic rhinosinusitis with nasal polyps) refractory to surgical and medical therapy; also licensed for asthma and eczema
- Neuropsychiatric adverse effects: depression, anxiety, suicidal ideation, aggression, sleep disturbances, hallucinations, obsessive-compulsive symptoms — black box warning
- MHRA (2020): risks highlighted; GPs should review all patients on montelukast; assess whether it is still indicated and whether benefit outweighs risk
- If prescribing: document that risk was discussed; PHQ-9 at initiation and at each review; warn patient and family/carer to report mood changes
- Prefer INCS + antihistamine ± azelastine over montelukast where possible — equivalent or better efficacy without the neuropsychiatric risk
- Montelukast is useful when AR coexists with asthma (modest benefit for both) — LTRA has bronchodilator properties
- Pregnancy: budesonide INCS (most safety data); cetirizine or loratadine antihistamine (generally considered safe); avoid decongestants; cromoglicate eye drops safe
- Rhinitis medicamentosa: stop oxymetazoline/xylometazoline (max 7 days rule — this is mandatory counselling when prescribing); start INCS during washout; taper decongestant if dependent; full recovery takes 2–4 weeks
- Nasal polyps: INCS first-line; if bilateral polyps not responding to 3 months INCS: ENT referral; dupilumab for CRSwNP; Samter's triad: avoid aspirin/NSAIDs; NSAID desensitisation at specialist centre
- Children: fluticasone furoate (Avamys) licensed from age 6; mometasone from age 3; non-sedating antihistamine; avoid chlorphenamine in children <6 (risk of paradoxical excitation)
Select patient scenario — personalised AR drug recommendations
"Tilt your head slightly forward; with your right hand, spray into your left nostril — that way you naturally spray towards the side wall rather than the middle dividing wall. Do the opposite for the right nostril. Sniff gently to bring the spray into the nose, but don't blow your nose straight away. Use it every morning — not just when it's bad. It takes 1–2 weeks to reach full effect."
INCS: most effective AR drug class, especially for nasal obstruction — this is the key prescribing point. Must be used REGULARLY not PRN. Negligible systemic absorption — address patient misconceptions about steroid side effects. Correct technique is essential — spraying towards septum causes epistaxis and reduces efficacy. Start 2 weeks before pollen season prophylactically for seasonal AR.
"The non-drowsy antihistamines like cetirizine are generally safe to drive on, but a small number of people do feel slightly drowsy. The first time you take it, please do not drive until you know how it affects you. If you feel any drowsiness: switch to loratadine or fexofenadine (I can give you those instead), and never take chlorphenamine — the older antihistamine in Piriton — if you need to drive."
Non-sedating antihistamines: cetirizine, loratadine, fexofenadine — all are first-line. Driving warning is mandatory: cetirizine causes mild sedation in ~10% — counsel on first dose; switch to loratadine/fexofenadine if sedation occurs. NEVER chlorphenamine for driving patients. Antihistamines address sneezing/itch better than obstruction — complementary mechanism to INCS; use both together for moderate-severe AR.
"This spray works very quickly — usually within 15–20 minutes. It can leave a bitter taste in your mouth — the way to reduce that is to tilt your head slightly forward and spray gently, then don't sniff hard afterwards. It is good as a top-up when you need quick relief, or before visiting somewhere you know has a cat."
Azelastine: intranasal antihistamine; fast onset (15 minutes); used as add-on at Step 2 when oral antihistamine + INCS are partially effective. Bitter taste is common and causes discontinuation — counsel on technique. Available as Dymista (combined azelastine + fluticasone) — superior to either alone; useful when Step 1 partially effective.
"This spray combines two medicines that work in different ways — one reduces inflammation (the steroid component), and the other blocks histamine (the antihistamine component). Together they work better than either alone. Use it twice a day, every day. The same technique applies as with the steroid spray — tilt slightly forward, spray towards the side wall, and don't sniff hard."
Dymista: combination azelastine + fluticasone; superior to either alone in trials for moderate-severe AR. Step 2 after inadequate response to INCS + oral antihistamine. Licensed from age 12. Bitter taste from azelastine component — counsel on technique. If Dymista insufficient: allergen immunotherapy referral.
"Before you start this tablet, I need to tell you about an important side effect. A small number of people experience changes in mood — feeling more anxious or low, sleep problems, or in rare cases more serious mood changes. Please tell me or your family member if you notice any of these changes, however mild. If you or someone at home notices significant mood changes, stop the tablet and contact us. This is why I am also asking about your mood today before starting it."
Montelukast: MHRA black box neuropsychiatric warning (2020) — depression, anxiety, suicidal ideation. MUST warn patient and carer before prescribing; PHQ-9 at initiation and review. Prefer INCS + antihistamine over montelukast where possible. Useful when AR + asthma: LTRA has bronchodilator properties. AERD (aspirin-sensitive): LTRA may be particularly effective. Churg-Strauss vasculitis: rare but important association with LTRA in high-dose asthma — watch for eosinophilia.
"Unlike the spray or tablets, which just control symptoms while you take them, this treatment actually changes how your immune system responds to grass pollen. It is a 3-year course, and the benefit tends to persist even after you stop. It is the closest thing to a long-term solution for hay fever. Most people get local irritation in the mouth early on — that is normal and usually settles. The main reason I would refer you to the specialist first is to confirm this is the right allergen and that you are a good candidate."
Grass pollen SLIT (Grazax): NICE-approved (TA246) disease-modifying treatment for severe grass pollen SAR not controlled on pharmacotherapy. 3-year course; effect persists post-treatment. Administered sublingually daily; first dose in clinic. Contraindicated in poorly controlled asthma (FEV1 <70%). Local oral reactions common and expected. AAI prescribed. SCIT (subcutaneous): also available; more effective for multiple allergens but requires hospital administration with 30-minute post-dose observation.
Academic and Work Performance
Studies demonstrate that AR during examination periods impairs performance equivalent to having a chronic moderate cold. UK students sitting GCSEs and A-Levels during the grass pollen season are disadvantaged if AR is untreated. Emily's ability to teach effectively, project her voice, and maintain concentration throughout the school day is directly impaired by nasal obstruction and fatigue from poor sleep.
"The research is clear that untreated hay fever affects concentration and performance at work and study as much as a persistent cold. Getting your treatment right before the summer term is genuinely clinically important — for you and for your students."Sleep and Fatigue
Nocturnal nasal obstruction — Emily's predominant complaint — disrupts sleep architecture. Nasal obstruction → mouth breathing → greater airway resistance → increased arousal → fragmented sleep → daytime fatigue and cognitive impairment. INCS is the most effective drug for nocturnal obstruction. Improvement in sleep quality is often the first and most striking benefit patients notice from starting regular INCS.
"I would expect the sleep to be the first thing that improves — usually within 1–2 weeks of using the spray every morning. Once the nasal lining is less swollen, the night-time blockage reduces significantly. Better sleep has a real knock-on effect on everything else."The Cat Question and Relationships
Advising allergen avoidance when the allergen is a partner's beloved pet is one of the more interpersonally sensitive conversations in allergy practice. Emily is in a relatively new relationship; the cat arrived with her boyfriend. The GP who demands the cat be removed may be right clinically but is clinically tone-deaf interpersonally. The GP who ignores the cat is clinically inadequate. The correct approach: honest about the allergen's role; empathetic about the difficulty; practical partial measures; immunotherapy as the long-term coexistence solution.
"I'm not going to pretend the cat isn't a significant factor — it almost certainly is. But I also understand this isn't a simple decision. The most practical immediate thing is keeping the cat out of your bedroom, which will reduce the overnight allergen exposure most. Immunotherapy — if we get to that — is actually the treatment that might let you live with a cat more comfortably long-term."Medication Adherence and Beliefs
Emily's concern about steroid sprays is the most direct barrier to optimal treatment adherence. It is not a trivial concern — it reflects a rational generalisation from what she knows about systemic steroids. Addressing it with a genuine, mechanistic explanation (not dismissal) is both respectful and clinically effective. Once the misconception is resolved, adherence is much more likely because the concern that was preventing use has been genuinely addressed.
"I'm glad you raised the steroid concern — it is very commonly misunderstood. The nasal spray works locally in your nose; less than 1% gets into your bloodstream. That is why it does not cause the effects you would get from steroid tablets. I would rather spend 2 minutes explaining that now than have you not use the treatment that would actually fix the blocked nose at night."2 Weeks — First Response to INCS
Is Emily using the INCS regularly? Is the technique correct? Initial improvement in nocturnal obstruction and sleep quality expected by 2 weeks. If sedation with cetirizine: switch to loratadine or fexofenadine. Spirometry result reviewed: asthma confirmed? If yes: ICS + SABA prescribed; treat both conditions.
6–8 Weeks — Treatment Assessment
Adequate response to INCS + regular antihistamine? If yes: continue; plan for next pollen season (start INCS 2 weeks prophylactically before April). If partial response: check technique; consider Dymista (combination spray). Discuss cat avoidance measures in detail. Montelukast if AR + asthma confirmed (with black box warning counselling). Allergy specialist referral discussion if inadequate response.
If Asthma Confirmed — 4 Weeks After ICS Start
Asthma symptom control (ACQ or RCP3Q); ICS technique; preventer vs reliever use understanding; spacer assessed; smoking status. AR and asthma: treat both simultaneously — do not achieve perfect asthma control without addressing AR. Trigger avoidance for both conditions (pollen, cat). Annual asthma review.
Annual Review
Seasonal AR: review in September (end of season); plan for next pollen season. Perennial AR: annual review. INCS: still needed? Adequate control? Montelukast: PHQ-9; still indicated? United airways: annual asthma review if asthma confirmed. Immunotherapy progress if referred. HDM/cat avoidance: review implementation and effectiveness.
AR monitoring essentials
At every prescription of INCS: check technique (spray towards lateral wall, not septum); confirm regular use (not PRN). At every antihistamine review: confirm non-sedating (not chlorphenamine/promethazine); driving safety counselled. Montelukast: PHQ-9 at initiation and at every review; neuropsychiatric warning given to patient AND carer; justify ongoing prescription. United airways: asthma screen at every AR diagnosis and at every annual review; spirometry if respiratory symptoms. Nasal decongestants: never prescribe for >7 days; rhinitis medicamentosa counselling at every decongestant prescription. Immunotherapy patients: annual specialist review; AAI available; asthma well-controlled (contraindicated if FEV1 <70%). Nasal polyps: ENT referral if bilateral polyps not responding to INCS after 3 months; 2-week wait if unilateral mass; Samter's triad documented with NSAID avoidance alert in records.
⚠ Three essential safety-net phrases for allergic rhinitis
Documentation requirements
- Not prescribing INCS — the most effective class for AR, particularly for Emily's dominant symptom (obstruction)
- Prescribing chlorphenamine — sedating antihistamine; not appropriate for a professional driver or teacher
- Not addressing steroid misconception — will result in non-adherence
- Not screening for asthma — united airways is mandatory
- Not addressing cat with empathy and realistic options
- Montelukast prescribed without MHRA neuropsychiatric warning
- INCS prescribed with technique counselled; regular (not PRN); 1–2-week onset explained
- Non-sedating antihistamine (regular); driving warning; not chlorphenamine
- Steroid misconception addressed with mechanism
- United airways: spirometry arranged; asthma screen positive acknowledged
- Cat: honest, empathetic, bedroom exclusion, immunotherapy option
- ICE all three; steroid misconception addressed non-dismissively
- Cat conversation empathetic; boyfriend's cat acknowledged; realistic options
- ARIA severity: teacher/work impact validated not trivialised
- Immunotherapy as long-term option discussed
- Closing question asked
Who you are
Emily Chen, 28, Year 4 primary school teacher. In a relationship with Tom — his cat (Biscuit, a tabby) moved into your shared flat 4 months ago. You live in south London in a ground-floor flat. Active: cycling to work (2.5 miles), gym twice a week. Non-smoker. No regular medications except cetirizine PRN. No known allergies except hay fever. No previous diagnosis of asthma but have noticed you cough more after cycling in spring and sometimes get slightly breathless on uphill stretches during May/June — you assumed this was just "being unfit." Pollen season was always June–August; symptoms began to appear in March–April too this year and are now present year-round. You are embarrassed to blow your nose constantly in class. You are tired from broken sleep — wake 2–3 times per night with blocked nose. Your voice is suffering (important for teaching). You are worried about using a steroid spray because your mum used steroid skin cream on her face for a long time and developed skin thinning — you have extrapolated this to nasal sprays.
Hidden concerns (reveal only if ICE explored)
Steroid concern (Ideas/Concerns): Mum developed skin thinning and had visible facial changes from long-term topical steroid cream. You have generalised this to all steroids. Will only be satisfied by a specific explanation of why a nasal spray is different from a skin cream — not by "it'll be fine" dismissal.
The cat (Concerns): You love Biscuit and Tom loves Biscuit and this has become complicated. You do not want to choose between your relationship and your health. If the GP tells you bluntly to "get rid of the cat," you will become defensive. If the GP acknowledges the difficulty and offers realistic partial measures, you will engage. Immunotherapy as a long-term option for cat allergy will genuinely interest you.
Testing (Expectations): You wonder whether you should have allergy testing — "to find out what I'm allergic to." If the GP explains clearly when allergy testing IS and IS NOT needed, you will accept the explanation. You do not want to be told "we don't need to do that" without an explanation.
The wheeze (not raised unless asked): You have noticed that exercising outdoors in spring causes a tight chest and slight wheeze. You assumed this was "just not being fit enough" or "pollen in the air." You will reveal this if asked specifically about chest symptoms with exercise. If asked, you will be surprised it might be relevant — "is that connected to hay fever?"
Clinical details if asked
- Seasonal pattern: June–August for 5 years; now March–April too (likely tree pollen sensitisation); year-round since Biscuit arrived 4 months ago
- Dominant nasal symptom: blocked nose, especially at night (wakes 2–3 times); rhinorrhoea (clear, anterior); sneezing (more in morning); nasal itch; no purulent discharge; bilateral symptoms
- Ocular symptoms: itchy, watery eyes during summer (May–July); red conjunctivae; worse outdoors; not persistent year-round
- Cetirizine: taking PRN when symptoms are bad; "maybe 3–4 times a week"; admits not taking it every day
- Exercise wheeze: cycling uphill in May/June causes slight wheeze and cough that resolves within 10 minutes of stopping; no wheeze at rest or in winter; no nocturnal cough (not awoken by cough)
- No current nasal decongestant use; has used oxymetazoline in the past "for a week or two"; no rebound symptoms currently
- Family history: mother has eczema; no asthma in family; father has no atopy
Reactions at key moments
- On INCS: "But what about the steroids thinning your skin?" → engages positively with specific mechanistic explanation; resists if dismissed; very satisfied if given percentage figure and comparison to tablets
- On cetirizine PRN: "Oh — I thought I was supposed to take it only when bad?" → receptive to explanation that regular is more effective during season
- On the cat: "I was hoping you wouldn't mention Biscuit..." → if empathetic and offering realistic options: "what is this immunotherapy you mentioned — tell me more"
- On wheeze: "Is that connected? I always thought I was just a bit unfit." → surprised but receptive; will accept spirometry
- Challenge line (if chlorphenamine or sedating AH prescribed): "Won't that make me drowsy? I can't teach if I'm drowsy."
Resolution: Emily will accept the consultation as satisfactory if the GP: (1) explains the systemic absorption difference between INCS and topical/systemic steroids specifically (less than 1%); (2) prescribes INCS (fluticasone or mometasone) with technique; (3) corrects cetirizine to regular; (4) addresses the cat empathetically with bedroom exclusion and immunotherapy as long-term option; (5) takes the wheeze seriously and arranges spirometry; (6) does not prescribe chlorphenamine; (7) explains when allergy testing is and is not needed; (8) gives a follow-up plan. She will disengage if: INCS is not prescribed; steroid concern is dismissed without explanation; the cat is discussed without empathy; wheeze is ignored; chlorphenamine is prescribed.
- Anaphylaxis: IM adrenaline + 999
- Unilateral nasal mass: 2-week wait ENT (malignancy)
- Samter's triad + NSAID exposure: 999/A&E if bronchospasm
- Bilateral polyps not responding to INCS: ENT
- Moderate-severe AR + asthma failing pharmacotherapy: allergy specialist for immunotherapy
- Suspected occupational rhinitis: OH + allergy
- Step 1: INCS + non-sedating AH (regular)
- Step 2: add azelastine or Dymista; consider LTRA
- Step 3: allergy specialist; immunotherapy
