Biologic & Monoclonal Antibody Therapy for Sinus and Allergy Conditions

At Richmond ENT, we offer advanced treatment options for patients with severe or difficult-to-control sinus and allergy conditions, including biologic (monoclonal antibody) therapies. These medications target specific immune pathways that drive inflammation and symptoms when standard treatments are not enough. Our physicians and nurse practitioners stay current with evolving immunology and biologic treatments through ongoing education, research, and professional society involvement. Dr. Armstrong was a principal investigator in clinical trials for Dupixent (dupilumab) and Nucala (mepolizumab). He was a consultant before the launch of Xolair for nasal polyps.

What Are Biologic (Monoclonal Antibody) Medications?

Biologics are highly targeted injectable medications designed to calm overactive immune responses. Unlike traditional allergy medications that broadly suppress symptoms, biologics work by blocking specific immune signals involved in chronic inflammation.

These therapies have transformed care for patients with:

  • Chronic sinus disease
  • Nasal polyps
  • Severe allergic disease
  • Asthma associated with sinus or allergy conditions

Biologics are not steroids or chemotherapy. They are precision therapies developed using advanced immunology.

Conditions Treated With Biologic Therapy

Biologic medications may be recommended for patients with:

Chronic Rhinosinusitis With Nasal Polyps (CRSwNP)

  • Persistent congestion or blockage
  • Loss of smell
  • Recurrent sinus infections
  • Symptoms despite surgery, sprays, or oral medications

Severe Allergic or Eosinophilic Sinus Disease

  • Ongoing inflammation despite optimal medical therapy
  • Frequent oral steroid use
  • Significant impact on quality of life

Asthma With Upper Airway Disease

  • Asthma linked to sinus or nasal inflammation
  • Patients requiring coordinated ENT and pulmonary care

Common Biologic Medications Used in ENT Care

Several FDA-approved biologics are used in otolaryngology and allergy care, including:

Your provider will determine which medication—if any—is appropriate based on your diagnosis, lab results, and clinical history.

How Biologic Therapy Is Given

  • Administered as an injection, typically every 2–8 weeks
  • Some medications are given in the office; others can be self-administered at home after training
  • Ongoing monitoring ensures effectiveness and safety

Biologics are intended for long-term disease control, not short-term symptom relief.

Who May Be a Candidate?

You may be a candidate for biologic therapy if you:

  • Have moderate to severe sinus disease or nasal polyps
  • Continue to have symptoms despite nasal sprays, medications, or surgery
  • Require frequent oral steroids
  • Have coexisting asthma or allergic disease
  • Meet specific clinical and insurance criteria

A thorough evaluation is required before starting therapy.

Safety and Side Effects

Biologic medications are generally well tolerated. Possible side effects may include:

  • Injection site reactions
  • Mild fatigue or headache
  • Rare allergic reactions

Your Richmond ENT provider will review risks, benefits, and monitoring requirements in detail before treatment begins.

Insurance Coverage

Many biologic medications are covered by insurance, including Medicare and major commercial plans, when medical criteria are met.

Coverage depends on:

  • Diagnosis and severity
  • Prior treatments tried
  • Insurance plan requirements

Our experienced team assists with insurance verification, prior authorization, and coordination of care.
