Biologic Therapies for Allergies, Asthma, and Immune Conditions

Biologic therapies are advanced treatment options used by allergists to manage moderate to severe allergic diseases and asthma. These targeted medications work by addressing specific immune pathways that cause inflammation, helping patients achieve better symptom control when traditional treatments are not enough.

At AllergySA, biologic therapies are used by our board-certified specialists who are highly trained in allergic and immune-mediated conditions.

What Are Biologic Therapies?

Biologic therapies are prescription medications made from living cells that target specific components of the immune system involved in allergic inflammation. Unlike standard allergy or asthma medications, biologics treat the underlying cause of disease rather than only relieving symptoms.

Biologics are typically administered by injection at regular intervals and are used for patients with chronic allergic conditions that are not well controlled with inhalers, antihistamines, nasal sprays, or topical treatments.

Conditions Treated with Biologic Therapy

Allergists use biologic medications to treat a variety of allergic and immune-driven conditions, including:

Asthma Treatment with Biologics

Biologic therapy is used for patients with moderate to severe asthma who continue to have symptoms despite inhaled medications. These treatments can:

• Reduce asthma attacks and flare-ups
• Improve breathing and lung function
• Decrease the need for oral steroids

Chronic Sinusitis with Nasal Polyps

For patients with chronic sinusitis caused by inflammation, biologic therapies can:

• Shrink nasal polyps
• Improve nasal congestion and breathing
• Restore sense of smell
• Reduce the need for repeat sinus surgery

Eczema (Atopic Dermatitis)

Biologics are an effective option for patients with moderate to severe eczema who have ongoing itching, inflammation, and skin irritation. These therapies help calm the immune response responsible for chronic eczema symptoms.

Chronic Hives (Chronic Urticaria)

Patients with chronic hives that do not respond to antihistamines may benefit from biologic treatment, which can significantly reduce hives, itching, and swelling.

Food Allergy (Select Patients)

In select cases, biologic therapies may be used as part of emerging food allergy treatment strategies under close supervision by an allergist.

Who Is a Candidate for Biologic Therapy?

You may be a candidate for biologic treatment if you:

• Have moderate to severe allergies, asthma, or eczema
• Continue to have symptoms despite standard medications
• Experience frequent flare-ups or steroid use
• Have conditions driven by immune system inflammation

Your allergist will perform a comprehensive evaluation, which may include allergy testing, lung function testing, and a review of prior treatments, to determine if a biologic is right for you.

Why See an Allergist for Biologic Therapy?

Allergists are experts in diagnosing and treating immune-driven allergic diseases. They are uniquely qualified to:

• Determine which biologic therapy is appropriate
• Monitor treatment safety and effectiveness
• Adjust care plans as symptoms change
• Coordinate long-term allergy and asthma management

Biologic therapies are most effective when used as part of a personalized, comprehensive treatment plan guided by an allergy specialist.
