Arizona is home to 32 verified allergists across 8 cities, with plans like Medicare, Aetna, and Cigna widely accepted. Every listing is checked against the federal NPI registry — no ads, no pay-to-rank.
Allergy and immunology practices treat seasonal and food allergies, asthma, eczema, sinus issues, and immune system disorders. Diagnostics include skin-prick testing, blood panels, and pulmonary function tests. Many practices offer in-office allergy shot (immunotherapy) programs for long-term relief.
Allergy & Immunology in Arizona — frequently asked questions
Real questions Arizona patients ask — from finding the right practice and understanding insurance to costs, visits, and when to seek care.

An allergist-immunologist diagnoses and treats allergies, asthma, and immune-system conditions — including hay fever, food and drug allergies, hives, eczema, sinus issues, and immune deficiencies. They find what triggers your symptoms and build a plan to control them.
Consider an allergist if allergies or asthma aren't well controlled with usual medication, you have frequent or severe reactions, you don't know what you're reacting to, or you've had a serious reaction to food, insect stings, or medication. Severe reactions with swelling or trouble breathing are emergencies — use epinephrine and call 911.
It depends on your plan. HMO plans usually require a referral from your primary care doctor, while PPO plans typically allow direct booking (often with higher cost out-of-network). Self-pay patients generally don't need one.
The two main methods are skin-prick testing — placing tiny amounts of allergens on the skin and watching for a reaction — and blood testing for allergy antibodies. For suspected food allergies, an allergist may perform a supervised oral food challenge, which should only be done in a medical setting.
Immunotherapy gradually exposes you to small, increasing amounts of an allergen — as shots or under-the-tongue tablets/drops — to build long-term tolerance and reduce symptoms. It's often used when medications aren't enough, and typically continues for three to five years for lasting benefit.
Many people notice improvement within the first several months to a year, with the full, lasting benefit building over a multi-year course (usually three to five years). Your allergist monitors progress and adjusts the plan along the way.
Allergy testing and immunotherapy are covered by most health plans, though you may owe a deductible and copays, and the serum and visits are billed separately. Confirm coverage with your insurer, especially for the ongoing cost of allergy shots.
Yes — allergists commonly diagnose and manage asthma, especially when it's allergy-related, helping identify triggers, optimize medications, and create an action plan. Well-controlled asthma means fewer flare-ups and ER visits.
See an allergist when the focus is identifying and treating allergies, asthma, or immune issues (including testing and immunotherapy). See an ENT for structural or surgical nose, sinus, ear, and throat problems. They often collaborate when chronic sinus symptoms have an allergic component.
Yes — allergists are the specialists for food allergies, using your history, testing, and, when needed, supervised oral food challenges to confirm a true allergy versus an intolerance. They also teach you how to avoid triggers and use emergency epinephrine.
The allergist takes a detailed history of your symptoms, triggers, and environment, examines you, and often performs skin or blood testing that same visit. From the results, they explain what you're reacting to and outline a treatment plan.
Seek emergency care immediately for signs of anaphylaxis — trouble breathing, swelling of the lips, tongue, or throat, widespread hives, dizziness, or fainting after exposure to a trigger. Use an epinephrine auto-injector if you have one and call 911; these reactions can escalate fast.
Yes — allergists treat children of all ages for food allergies, eczema, asthma, and environmental allergies, using child-appropriate testing. Early diagnosis helps families manage triggers and prevent serious reactions.
They're closely related and often the same physician — an allergist/immunologist. The 'allergist' side emphasizes allergies and asthma, while the 'immunologist' side focuses on broader immune-system disorders like immune deficiencies and autoimmune-related conditions.
Yes — chronic hives (urticaria) and eczema are common reasons to see an allergist, who can look for triggers and underlying causes and offer treatments beyond over-the-counter options, including prescription and newer biologic medications for stubborn cases.
Beyond seasonal allergies, allergists manage asthma, year-round nasal allergies, sinus problems, food and drug allergies, insect-sting allergies, eczema and hives, and certain immune-system disorders. They're the specialist when symptoms are allergic or immune in origin.
