ENT vs Allergist:
Who Should You See?

Two Specialists, Overlapping Expertise

Both otolaryngologists (ENTs) and allergists/immunologists test for and treat allergies. Either specialist can order skin-prick or blood allergy testing, prescribe medications, and administer immunotherapy to reduce your sensitivity to allergens over time. For straightforward allergic rhinitis — sneezing, itchy eyes, runny nose triggered by pollen or dust — either can be a good starting point.

The key difference is scope. ENTs are also trained surgeons who diagnose and correct structural problems inside the nose and sinuses — a deviated septum, nasal polyps, or chronically blocked sinus drainage pathways — that no amount of medication can fix. According to the American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS), otolaryngologists' scope explicitly includes allergy evaluation and immunotherapy alongside surgical management of the upper airway. Capital ENT offers in-house allergy testing and immunotherapy at the same practice that performs balloon sinuplasty, septoplasty, and endoscopic sinus surgery — so the full path from diagnosis to medical treatment to structural correction is available under one roof.

Consider an ENT when structural problems are involved

If your symptoms include facial pressure or pain, recurrent sinus infections that never fully clear, nasal blockage on one side, post-nasal drip, or reduced sense of smell — structural factors are likely in play. A deviated septum, nasal polyps, or narrowed sinus drainage openings can perpetuate symptoms even after allergies are controlled medically. An ENT can perform nasal endoscopy and in-office CT imaging to identify these problems and — if indicated — correct them surgically. An allergist is not trained to perform these procedures and would refer you to an ENT for that component of care.

An allergist is the natural choice when your symptoms are primarily systemic — widespread skin reactions, food allergies, asthma that isn't responding to standard treatment, or complex immune-mediated conditions. Asthma is primarily managed by allergists and pulmonologists; some ENTs integrate asthma care through the unified-airway model, but this is not universal. For multi-system allergic disease or for patients whose primary issue is asthma control rather than upper-airway obstruction, an allergist/immunologist or pulmonologist is often the more appropriate lead specialist.

A note on immunotherapy options

Both ENTs and allergists offer allergy shots (subcutaneous immunotherapy, SCIT) and FDA-approved sublingual immunotherapy tablets. Current FDA-approved sublingual immunotherapy exists as tablets for specific allergens (grass pollen, ragweed, and dust mites). Custom aqueous sublingual "drops" are used off-label in the United States — there is no FDA-approved formulation or standardized dosing for aqueous SLIT drops — and their use varies by practice. The AAO-HNS Clinical Practice Guideline: Immunotherapy for Inhalant Allergy (Gurgel 2024) provides the current evidence base for immunotherapy options offered by ENT specialists.
