Hay Fever Injection London 2026: What's Available Now After Kenalog Discontinuation
Medically reviewed by The Online GP by The Wellness clinical team | Last updated: April 2026
The hay fever injection that millions of people in the UK searched for over the past two decades, Kenalog, was discontinued by its manufacturer in June 2025 and was never licensed for hay fever in the UK in the first place. The MHRA has taken regulatory action against clinics advertising Kenalog as a hay fever treatment. This guide explains exactly what happened, what is available instead in London in 2026, what each option costs, and how to choose the right pathway based on the severity of your symptoms. At The Online GP by The Wellness in Marylebone, we offer every licensed alternative to Kenalog, from a £150 consultation with optimised prescription medication through to full allergen immunotherapy.
If you have been searching for a hay fever injection in London this season, the answer has changed since 2024. There are now better, safer, and more clinically appropriate options. Here is the complete picture.

Can I still get a hay fever injection in London in 2026?
The historical hay fever injection, Kenalog (triamcinolone acetonide), was discontinued in the UK in June 2025 by manufacturer Bristol-Myers Squibb. It was never licensed in the UK for hay fever, meaning all private use was off-label, a fact most patients were never told. Some private clinics still hold pre-discontinuation stock, but the MHRA and the Committee of Advertising Practice (CAP) have actively pursued enforcement action against clinics advertising Kenalog for this indication. The treatment is also no longer available on the NHS, having been withdrawn in 2018 over safety concerns.
What this means in 2026: the era of the steroid jab for hay fever is effectively over. Reputable London clinics are pivoting to licensed, evidence-based alternatives. The Online GP by The Wellness does not offer Kenalog, in line with MHRA guidance and current best practice. We offer every other licensed pathway including optimised prescription medication, short oral steroid courses where clinically appropriate, comprehensive allergy testing, and allergen immunotherapy (the actual hay fever vaccine).
For patients who specifically want a single injection for symptom control, the available licensed alternative is subcutaneous allergen immunotherapy (allergy shots), which is fundamentally different from Kenalog because it treats the underlying allergic disease rather than suppressing the immune system. SCIT requires regular clinic visits over three years rather than a single seasonal injection.
Why was the hay fever injection discontinued?
Kenalog was discontinued for a combination of regulatory, clinical, and commercial reasons that converged in 2025. The regulatory position has been clear for years: the Medicines and Healthcare products Regulatory Agency (MHRA) never licensed Kenalog for hay fever in the UK, so every prescription was off-label. The MHRA and CAP issued public guidance in 2023 and 2024 making clear that advertising Kenalog as a hay fever treatment misleads patients about its licensed use, and pursued enforcement action against several private clinics.
The clinical rationale concerns the risk-benefit balance for a non-life-threatening condition. Kenalog is a long-acting corticosteroid that suppresses the entire immune system for several weeks after injection. The NHS withdrew it from routine use in 2018 because the systemic side effects, which include increased risk of infection (chickenpox, shingles, severe flu), weight gain, mood changes, insomnia, raised blood pressure, fluid retention, and rare but serious complications including avascular necrosis of the femoral head and adrenal suppression, were judged to outweigh the benefit when targeted nasal corticosteroids and antihistamines achieve similar symptom control with much lower systemic exposure.
The commercial decision in June 2025 by Bristol-Myers Squibb to discontinue UK supply reflected falling demand from licensed indications (joint injections, certain dermatological conditions, allergic asthma) combined with the regulatory pressure on off-label hay fever use.
The result is a market shift. Generic triamcinolone is still available in some forms, but most licensed UK supply has now exhausted, and patients searching for "hay fever injection London" in 2026 are increasingly being directed to safer, evidence-based alternatives.

What are the best alternatives to the hay fever injection?
The best Kenalog alternative depends entirely on the severity and pattern of your symptoms. There is no longer a one-size-fits-all "jab" answer. A structured approach moves through four progressively more intensive options, with most patients achieving full control at step 1 or 2.
Step 1: Optimised prescription medication. Around 70 percent of people who think they need a hay fever injection have not yet used standard medications correctly. Maximum licensed doses of second-generation antihistamines (fexofenadine 180mg, cetirizine 10mg, or loratadine 10mg, all once daily), combined with consistent twice-daily intranasal corticosteroid spray (mometasone, fluticasone, or beclometasone) using correct technique, plus antihistamine or mast cell stabiliser eye drops where eye symptoms predominate, will fully control symptoms in most patients. The catch is that "consistent" means daily for the entire pollen season, not as needed when symptoms flare.
Step 2: Short oral steroid course for severe acute symptoms. For severe symptoms requiring rapid relief, particularly around major life events (exams, weddings, important presentations, sporting competitions), a short course of oral prednisolone (typically 30mg daily for 5 to 7 days) provides comparable relief to a Kenalog injection with substantially shorter steroid exposure. Risks of a 5-to-7-day course are minimal in most adults. This is a recognised, evidence-based option supported by BSACI guidelines for severe seasonal flares, and is the modern licensed equivalent of the historical "jab".
Step 3: Allergen immunotherapy (the actual hay fever vaccine). For patients with persistent severe symptoms across multiple seasons, MHRA-licensed sublingual immunotherapy (Grazax for grass pollen, Acarizax for house dust mite, Itulazax for birch pollen) or subcutaneous immunotherapy retrains the immune system over three years and produces sustained relief lasting many years. This is the only disease-modifying treatment.
Step 4: Specialist combined approach. For complex cases including multi-allergen sensitivities, co-existing asthma, or non-allergic rhinitis components, full specialist assessment combines targeted immunotherapy with optimised pharmacotherapy and lifestyle management.
How effective is a short oral steroid course compared to a Kenalog injection?
A 5-to-7-day course of oral prednisolone produces similar symptom control to a Kenalog injection but with two crucial advantages: much shorter steroid exposure (peak 5 to 7 days versus several weeks) and reversibility (you can stop if side effects develop). For severe acute hay fever, this is the modern licensed equivalent.
A typical regimen is 30mg of prednisolone once daily for 5 to 7 days, taken in the morning to minimise insomnia. Symptom relief usually begins within 24 hours and is substantial within 48 to 72 hours. This is comparable to Kenalog, which typically takes 24 to 48 hours to produce effect. Where Kenalog suppresses the immune system continuously for 3 to 6 weeks, oral prednisolone exposure ends within days of stopping, returning your immune function to baseline rapidly.
Side effects of a single 5-to-7-day course are typically minor: mild fluid retention, some sleep disturbance if taken too late in the day, and occasionally mood elevation or irritability. Compare this with documented Kenalog complications: increased infection risk extending weeks beyond the injection, weight gain that can persist for months, persistent mood changes, raised blood pressure, and rare but severe complications including avascular necrosis.
This option is suitable for adults without contraindications including poorly controlled diabetes (where short steroid courses can transiently affect blood glucose and require monitoring), active infection, severe osteoporosis, or pregnancy. It requires individual assessment by a GMC-registered doctor and is not a routine prescription, but for clinically appropriate patients facing severe symptoms around important events, it is the closest licensed equivalent to the historical hay fever jab.

What does a hay fever consultation cost in London?
Hay fever consultation costs in London vary widely, from £49 for a basic phone consultation to £500 or more for a consultant-level allergy specialist on Harley Street. The right level depends on the complexity of your case, whether you need testing, and whether you are seeking a quick prescription or a structured long-term plan.

The Wellness pricing sits deliberately at the premium-but-accessible level: priced for serious medical care with experienced doctors and full diagnostic capability, but without the consultant-fee markup of consultant-led Harley Street practices for cases that do not require consultant input.
What does the modern hay fever pathway look like at The Wellness?
A typical patient pathway at The Online GP by The Wellness moves from initial assessment through diagnostic testing to definitive treatment in a structured, evidence-based sequence designed to deliver outcomes rather than just appointments.
Day 1: Initial consultation (60 to 90 minutes for new hay fever patients, including pre-appointment forms). Your GMC-registered doctor takes a detailed history covering symptom pattern, severity, seasonality, triggers, prior treatment response, and impact on sleep, work, and quality of life. Examination focuses on nasal passages, throat, eyes, and chest. Validated questionnaires (Total Nasal Symptom Score, Rhinoconjunctivitis Quality of Life Questionnaire) are used where helpful. By the end of the appointment, you have a working diagnosis, a recommended diagnostic plan if testing is needed, and an immediate symptom control prescription if appropriate.
Days 2 to 5: Allergy testing (where indicated). Specific IgE blood testing requires a 5-minute blood draw with results in 24 to 48 hours. Skin prick testing produces immediate 20-minute results but requires antihistamine cessation 72 hours beforehand. ALEX³ molecular testing for complex cases takes 5 to 7 working days.
Day 7 to 14: Results review and treatment plan. Once diagnostic information is complete, a 30-minute follow-up consultation reviews findings, confirms the working diagnosis, and produces a written treatment plan. For most patients, this is the point at which a definitive treatment route is chosen: optimised prescription, short oral steroid course, or allergen immunotherapy.
Ongoing care. For patients on immunotherapy, 6-monthly reviews are built into the treatment package. For patients on optimised prescriptions, 12-monthly reviews ensure medication remains appropriate. WhatsApp access to your treating clinician is available throughout for urgent issues or interim queries.

Why does The Wellness not offer Kenalog injections?
We made a deliberate decision in 2025 not to offer Kenalog for hay fever, even when remaining UK-licensed stock was available. This decision rests on three considerations and reflects the position taken by every major UK allergy professional body including BSACI, the Royal College of Physicians, and the British Medical Association.
First, regulatory compliance. Kenalog is not licensed in the UK for hay fever. Prescribing it for this indication is off-label, and advertising it as a hay fever treatment has been actively pursued by the MHRA and CAP as misleading to patients. As a CQC-registered private clinic with GMC-registered doctors, The Wellness operates strictly within MHRA licensing and BSACI guidelines.
Second, clinical safety. Modern allergy medicine views the risk-benefit balance of Kenalog as unfavourable for hay fever. The systemic side effect profile of a long-acting steroid is disproportionate to the symptom control needed for a non-life-threatening condition when superior alternatives exist. Where rapid intervention is genuinely required, a short oral steroid course delivers comparable relief with substantially shorter steroid exposure and full reversibility.
Third, long-term outcomes. Patients receiving Kenalog injections year after year never address the underlying allergic disease. The steroid simply suppresses the symptoms while the allergy progresses, sometimes worsening over time and increasing the risk of developing asthma. Allergen immunotherapy retrains the immune system itself and produces lasting benefit. We believe patients deserve the option of resolution, not just suppression.
This positioning aligns The Wellness with the modern, evidence-based, MHRA-compliant approach to hay fever management taken by leading UK allergy clinics including Imperial College Healthcare, Guy's and St Thomas', and the major Harley Street consultant practices.
How do I choose the right hay fever treatment for me?
The right hay fever treatment depends on three factors: severity of symptoms, duration of suffering, and your goals (rapid one-season relief versus long-term resolution). The questions below will help you orient before your consultation.
Are your symptoms mild and intermittent? Standard over-the-counter antihistamines and intranasal sprays, used correctly and consistently, will likely control them. A pharmacy consultation may be sufficient.
Are your symptoms moderate and persistent despite OTC treatment? A GP consultation to optimise prescription medication is the right next step. Maximum-dose fexofenadine, an effective intranasal steroid, and the right eye drops controls 70 to 80 percent of these cases. The Wellness offers this from £49 (phone) or £79 (in-person).
Are your symptoms severe but seasonal, and you are coming up to a critical event (exam, wedding, presentation)? A short oral steroid course is the modern licensed equivalent of the Kenalog jab. This requires individual assessment via our Severe Hay Fever Express Plan (£195).
Have your symptoms been severe for multiple seasons despite optimal medication? Allergen immunotherapy is likely the right pathway. Allergy testing first identifies the right allergen target. Initial consultation and testing typically £445 (£150 + £295), then immunotherapy initiation £395 plus ongoing medication.
Are you uncertain whether your symptoms are even hay fever? Around 25 to 30 percent of "hay fever" cases turn out to be non-allergic rhinitis, vasomotor rhinitis, chronic sinusitis, or local allergic rhinitis, none of which respond to standard hay fever treatment. A specialist consultation with appropriate testing settles the question.
Frequently asked questions
Where can I get a hay fever injection in London in 2026?
Most reputable London clinics no longer offer Kenalog because of its discontinuation, off-label status for hay fever, and MHRA regulatory action. Some smaller clinics still offer remaining stock. We recommend caution: a long-acting systemic steroid for a non-life-threatening condition is rarely the right clinical choice when modern licensed alternatives, including short oral steroid courses for severe acute symptoms and allergen immunotherapy for long-term resolution, deliver better outcomes with lower risk.
Is the hay fever injection still available privately?
Limited remaining UK-licensed Kenalog stock exists at some private clinics, but ongoing supply is not guaranteed and the MHRA continues to pursue advertising compliance. The Wellness does not stock or administer Kenalog for hay fever and instead offers the full range of licensed alternatives.
Can I still buy Kenalog online?
No. The National Pharmacy Association has issued public warnings against buying Kenalog from online sellers, beauty salons, or social media. Unregulated supply may contain counterfeit medication, incorrect dosages, or contamination. Self-administration of any injectable steroid is dangerous and illegal under UK medicines law.
How long does an oral steroid course take to work for hay fever?
Symptom relief from a 30mg daily prednisolone course typically begins within 24 hours and is substantial within 48 to 72 hours. Full effect is reached by day 4 to 5 of a 7-day course. This is comparable to the onset speed of a Kenalog injection but with the major advantage that exposure ends within days of stopping rather than continuing for weeks.
Are there any new hay fever injections coming to the UK?
The active development pipeline focuses on biologic therapies (such as omalizumab and dupilumab) for severe cases with multiple allergic conditions, and on allergen immunotherapy delivery innovations. None of these is positioned as a single seasonal injection equivalent to Kenalog, and the consensus among allergy specialists is that the era of suppressive systemic steroid jabs for hay fever is over. Future injectable treatments will be allergen-specific and disease-modifying.
Will my GP refer me for an NHS hay fever injection?
NHS GPs generally cannot refer for Kenalog because it has been withdrawn from NHS hay fever care since 2018 and was never licensed for the indication. NHS specialist allergy referrals are available for allergen immunotherapy under NICE guidance (TA246, TA1066, TA1106), but waiting times are typically 6 to 12 months. Private pathways at The Wellness offer specialist assessment within 24 to 72 hours.
Can I get a hay fever injection if I have a wedding next week?
For severe acute symptoms around a major event, a short oral prednisolone course is the licensed, evidence-based, rapid-onset option and replaces Kenalog as the modern equivalent. We can typically arrange a same-day in-person consultation at our Marylebone clinic for clinically appropriate patients via our Severe Hay Fever Express Plan (£195). WhatsApp us on +44 7961 280835 for urgent enquiries.
