What our patients are saying
"My hay fever has gone from life-disrupting to barely noticeable." I’ve had hay fever for the past ten years, and every time summer approaches, I get anxious. While most people look forward to the sunshine, I’ve come to dread it. For me, summer has meant months of grogginess, constant tiredness, and relentless itching... No standard medication worked. Antihistamines either left me drowsy or made no difference at all. I had no choice but to manage the symptoms rather than tackle the cause, and even then, the relief was limited. I’ve been on treatment for half a year now, and I’ve already noticed a big difference this hayfever season. The symptoms have become a mild annoyance rather than something that completely disrupts my life. I can finally sleep through the night without being woken by painfully itchy ears and nose. I’m genuinely excited to see how things progress in the years ahead. For the first time in a decade, I feel hopeful that I might be able to enjoy summer like everyone else.

"I’m on the path to finally ending years of relentless hay fever." I’ve had terrible hayfever symptoms all my life and take a myriad of drugs on a daily basis from January until September. When I heard about immunotherapy I was desperate to try to reduce or even remove my symptoms. Setup with Allergy Rhino was really easy. Website easy to use and professional and that was reassuring. I had a consultative call and then did a blood test at home which was a professional 3rd party provided standard kit and was easy to use. The results confirmed I reacted to various pollens (which I absolutely already knew but it was great to see it on paper!) and so we started the process. The nurse and doctor (remotely) supported me well and I was able to confidently continue and now I am just on a path to success (hopefully). It will take some time but I am looking forward to finally reducing these life affecting symptoms. Hard not to recommend - anything to stop me taking 3 hayfever tablets, eye drops and sometimes a nasal inhaler every day for 9 months of the year!

Allergy immunotherapy explained
What is allergy immunotherapy?
It’s the only treatment that tackles the root cause of allergies. Instead of just masking symptoms, it works by gradually retraining your immune system to stop overreacting to allergens like pollen, dust mites, or pets.
How does it work?
You take small, controlled doses of the allergen as a tablet or spray under your tongue. Over time, your immune system builds tolerance, leading to fewer symptoms and lasting relief.
Why AllergyRhino immunotherapy?
Our treatments are clinically proven, trusted by leading allergists, and easy to take at home. Most patients see meaningful improvements within months, with benefits that last long after treatment ends.
The Science
Our treatment is a form of allergy desensitisation. By safely exposing your immune system to tiny daily doses of the substances you’re allergic to (via a spray under the tongue), your body gradually becomes tolerant. You react less to pollen, dust mites, pets or moulds. This tackles the root cause, unlike antihistamines or nasal sprays that only mask symptoms.

SLIT is well-studied and recognised as safe and effective in multiple independent reviews (World allergy organisation position paper).
-
Benefits are durable: many patients continue to feel better years after finishing a full course.
SLIT is widely used across Europe (e.g., prescribed far more frequently in Germany) and is increasingly adopted in progressive healthcare systems.
-
Because it’s needle-free, home-based, and disease-modifying. In countries like Germany, SLIT is prescribed dramatically more often than shots. Real-world and clinical data show consistent, increasing relief over multi-year courses, aligning with our goal: long-term control rather than seasonal firefighting.
Yes. Immunotherapy changes how your immune system behaves. Evidence shows benefits build over time across a typical ~3-year course and often persist ≥8 years after completion.
In the UK, allergy care is often limited to short-term relief medicines or allergy shots available only in specialist centres. Sublingual sprays are widely used in Europe (for example, prescribed far more often in Germany and in the USA) but are still not standard in NHS practice.
AllergyRhino makes this proven therapy more accessible in the UK through a combination of pharmacy partners, online consultations, and UK-regulated prescription sprays.
Will this work for me?
You’re likely a good fit if you have hay fever or year-round symptoms (grass/tree/weed pollens, house-dust mite, pet dander, mould), if OTC meds aren’t enough, and you want a long-term fix.
-
Pollens: grass, tree, weed (seasonal hay fever)
-
House dust mite (year-round)
-
Pet dander: cat, dog
-
Mould spores
Some additional indications are in development as evidence and supply pathways expand.
-
Most patients notice improvements in 3–6 months, with significant relief at 12 months. To achieve long-term results, the typical course is around 3 years.
You won’t need to stay on SLIT forever—once your immune system has been retrained, the benefits usually persist for years after stopping.
Studies show patients continue to benefit for many years after completing therapy. In some cases, the improvements have lasted 8+ years. For many, it feels like being allergy-free.
