About Allergy Ireland


Allergy services at Slievemore Clinic began as a part-time facility in 1984.  
Almost 40 years later, Allergy Ireland has evolved into the most highly specialised and resourced allergy clinic in Ireland. Our doctors use advanced flexible fiberoptics and comprehensive allergy testing in combination with the latest anti-allergy treatments, Immunotherapy and Rhinolight. 

Allergy Testing:

  • Skin Prick Testing: This is the gold standard in clinical allergy testing. We test for a very wide range of aero-allergens and food allergens.
  • Nose and Sinus assessment using Olympus ENF Type V2 Video fiberoptics.
  • All allergy testing is immediately followed by a long consultation with one of our Doctors to create a personalised management plan.

Allergy Treatment

  • We have detailed, effective and proven treatment plans. In addition, we also have specialised treatment options such as Rhinolight and Immunotherapy.
  • Rhinolight phototherapy: Allergy Ireland was the first allergy facility in UK/Ireland to introduce this endonasal treatment. Phototherapy is commonly used in Hospital settings to treat Psoriasis and other skin conditions. It uses a part of the visible light spectrum and a certain safe range of UV light to reverse the allergic inflammation of the nasal mucosa & turbinates. It is effective in treating the vast majority of cases of Allergic Rhinitis.
  • Immunotherapy has emerged as an additional highly effective and safe medical treatment against dust and pollen allergies. It is considered like vaccinating yourself against your allergy and involved taking a tiny dose of allergen daily for a period of time to provide lifelong protection.

Patient Information 

  • You do not need a referral to make an appointment. 
  • We can accommodate two patients from the same family on the same day but this must be booked in advance so that extra time is allocated.
  • Allergy Ireland use quality assured extracts sourced from Bio-Diagnostics (UK) and Greer Labs (USA).
  • Blood tests may be used in conjunction to skin prick testing when life threatening food allergy is identified.
  • We have a close working relationship with Crumlin Children’s Hospital and Specialist ENT services.
  • Specialist referrals: if we can’t make you better we’ll suggest an appropriate specialist to take over your care.  For example, we work with a select group of experienced and skilled ENT specialists.

The fees for our services are not covered by any of our national health insurance agencies.  You can reclaim some of the fees if you have health insurance so it’s important to hold on to your receipts.  Also, you can claim health costs against tax on the Med 1 form (ask your accountant about this or read the advice on the Revenue website).

Overseas health insurance companies may cover the fees but it’s up to you to check this with your insurer.
