Targeting Allergists in the US

Allergists are one of the highest-value and hardest physician audiences to reach online. There are only around 6,000 board-certified Allergists in the US, one of the smallest specialties in medicine, yet they own the fast-growing allergy, asthma and atopic disease market as biologics and immunotherapy reshape how these conditions are treated. Our HCP Targeting is audience-based, not Contextual, so we reach the Allergist as a clinician and as a person, wherever they browse: news, finance, technology, sport, travel, food, lifestyle and health content alike. That is broader reach across brand-safe, premium inventory, through Programmatic and Managed Campaigns, in the US.

HCP Targeting with USA Flag & Stethoscope

Our HCP Targeting (including this Allergist Targeting Segment) is available in the USA only, delivered with geo-targeting to the United States.

Need to reach HCP audiences based outside the US? It’s harder, but we’ve had success targeting them through Clinical Websites and Contextual Targeting.

The Allergist Audience

There are only around 6,000 board-certified Allergists in the US, one of the smallest and most specialized physician groups in medicine, just as allergy, asthma and atopic disease keep climbing across the population. That scarcity is the point: Allergists run high-volume outpatient practices and own the day-to-day management of Allergic Rhinitis, Food Allergy, Asthma, Atopic Dermatitis, chronic Urticaria and anaphylaxis. They control the allergy testing, immunotherapy and biologics decisions in this space and keep patients on long-term therapy, which makes them a high-value audience for Pharmaceutical, Biologics, Diagnostics and Healthcare Technology brands. As atopic and allergic disease rises and the biologics pipeline expands, Allergists sit at the center of a high-growth market and are a high-value audience to reach at scale.

Why Advertise to Allergists

Allergists sit on top of one of the fastest-growing specialty drug markets in medicine, built around Biologics and immunotherapy. On the drug side they choose and manage Biologics for Asthma and Atopic disease like Dupilumab, Omalizumab, Mepolizumab, Benralizumab and Tezepelumab, Allergen Immunotherapy delivered as allergy shots and sublingual tablets, Oral Immunotherapy for Food Allergy, Epinephrine auto-injectors, and Antihistamines. On the diagnostics side they drive demand for allergy skin and blood testing and component-resolved diagnostics. Their influence reaches well beyond a single prescription. Allergists shape formularies for high-cost Biologics, sit on the committees that decide which agents a plan will cover, and set the treatment pathways that Primary Care, Pulmonology and Dermatology follow for allergic disease. Winning the Allergist shapes prescribing far downstream.

Take an “Always On” Strategy for Targeting Allergists

Allergists TargetingAllergists are one of the smallest and busiest physician audiences in medicine: booked out for months, with new-patient waits that can stretch far longer, and full clinics managing complex chronic disease. You can rarely predict when one is online, whether it is between patients, after a full clinic day or on a weekend.

That is why we recommend an Always On strategy for an audience like this: run the campaign 24/7, 365 days a year so you reach Allergists whenever they surface, not just in a short burst. Continuous delivery builds reach and frequency over time, so you are already in front of them by the time your message matters most.

An Always On budget goes further with an Omnichannel approach. Rather than betting on one screen, you reach Allergists across the whole day: on their phone between patients, through a podcast in the car, on the office desktop between cases, and on Connected TV while they unwind at home. Same audience, more moments, more chances for your message to land.

Frequently Asked Questions (FAQs)

An Allergist, board-certified in Allergy and Immunology, is a physician who diagnoses and treats allergic disease and disorders of the immune system. They complete Internal Medicine or Pediatrics training plus an Allergy and Immunology fellowship, and they manage conditions like Allergic Rhinitis, Asthma, Atopic Dermatitis, Food Allergy, chronic Urticaria, anaphylaxis and drug and insect allergy. They use allergy testing, immunotherapy and Biologics to control allergic and immune disease.
There are only around 6,000 board-certified Allergists in the US, one of the smallest physician specialties. Demand keeps rising as allergy, asthma and atopic disease climb and biologic therapies expand. That makes Allergists a scarce, high-value and hard-to-reach audience.
Allergists treat allergic and immune-mediated disease across all ages: Allergic Rhinitis and hay fever, Asthma, Food Allergy, Atopic Dermatitis and eczema, chronic Urticaria and hives, drug and insect allergy, anaphylaxis, sinus disease and, alongside immunologists, primary Immunodeficiency. They manage patients with allergy testing, allergen immunotherapy and biologics.
Very little: both hold the same board certification in Allergy and Immunology. Allergist is the practice-facing title most patients use, focused on allergy, asthma and immunotherapy in an outpatient clinic. Immunologist emphasizes the immune-system side, including primary Immunodeficiency and more complex immune disease. Most specialists in this field do both, which is why the title Allergist-Immunologist is common.
