What is Biologic Management?
Biologic therapy represents a revolutionary advancement in asthma and allergy treatment. Unlike traditional medications that provide broad symptom relief, biologics are precision medicines made from living organisms that target specific molecules and immune pathways responsible for inflammation in your airways.
When you have severe asthma or chronic allergic conditions, certain immune system proteins—such as IgE antibodies, interleukins (IL-4, IL-5, IL-13), or thymic stromal lymphopoietin (TSLP)—drive persistent inflammation in your lungs. Biologics work by blocking these specific inflammatory pathways at their source, reducing airway swelling, mucus production, and the frequency of asthma attacks.
Biologics are administered as either a subcutaneous injection (similar to an insulin shot) or an intravenous (IV) infusion, typically given every 2 to 8 weeks depending on the specific medication. They work as add-on therapy, meaning you continue using your inhaled medications alongside biologic treatment. Over time, many patients are able to reduce their reliance on oral corticosteroids and rescue inhalers.
At NY Allergy & Sinus Centers, our allergists will review your medical history, asthma severity, biomarker test results (such as IgE levels, eosinophil counts, and FeNO), and treatment response to determine whether biologic therapy is right for you.
Am I a Candidate for Biologics?
- You may qualify for biologic therapy if:
- You have moderate-to-severe asthma that remains uncontrolled despite proper use of inhaled corticosteroids and long-acting bronchodilators
- You experience frequent asthma symptoms that disrupt sleep, daily activities, or work/school
- You require oral corticosteroids multiple times per year to manage exacerbations
- You have had emergency room visits or hospitalizations due to asthma attacks
- Your blood tests show high eosinophils (a type of white blood cell linked to inflammation) or elevated IgE antibodies
- You have been diagnosed with allergic asthma or eosinophilic asthma
Your allergist will perform biomarker testing—including blood tests, FeNO testing, and spirometry—to determine which biologic is most appropriate for your specific asthma type.

Advantages of Biologic Therapy
Targets the Root Cause of Inflammation
Significant Reduction in Asthma Attacks
Improved Lung Function & Breathing
Reduced Need for Oral Corticosteroids
Enhanced Quality of Life
Excellent Safety Profile
Biologics are highly targeted and generally well-tolerated, with most side effects being mild (such as injection site reactions or headache). Serious adverse events are rare
What You Need to Know About Biologic Therapy
Biologic therapy is a long-term commitment that requires ongoing monitoring and adherence to your treatment schedule. Here are key points to understand:
- Biologics are add-on therapy. You will continue using your inhaled medications (corticosteroids and bronchodilators) alongside biologic treatment. Do not stop your inhalers unless instructed by your allergist.
- Results take time. Biologics do not work immediately. It may take several weeks to months before you notice significant improvement in your asthma symptoms. Stay consistent with your treatment schedule.
- Regular dosing is critical. Biologics are administered on a set schedule (every 2, 4, or 8 weeks depending on the medication). Missing doses can reduce effectiveness and lead to symptom relapse.
- In-office monitoring required. For safety, biologic injections and infusions are administered in our office where we can monitor you for any immediate reactions. You will remain under observation for a period after each dose.
- Insurance coverage and assistance programs. Biologics are specialty medications and can be expensive. Most insurance plans cover them with prior authorization. We will help you navigate insurance approval and connect you with manufacturer assistance programs to reduce out-of-pocket costs.
- Not a cure, but transformative control. Biologics do not cure asthma, but they can dramatically improve disease control, reduce exacerbations, and allow many patients to live fuller, more active lives with fewer limitations.
Biologic Management Frequently Asked Questions
How do I know which biologic is right for me?
Your allergist will determine the most appropriate biologic based on your asthma type (allergic vs. eosinophilic vs. non-Type 2), biomarker test results (IgE levels, eosinophil counts, FeNO), symptom severity, and treatment history. Some patients may be candidates for multiple biologics, in which case your allergist will recommend the one most likely to benefit you based on current clinical evidence and your specific situation.
How are biologics administered?
Most biologics are given as a subcutaneous injection (a shot under the skin, similar to an insulin injection). Some biologics, like Cinqair, are administered as an intravenous (IV) infusion. All biologic doses are given in our office by trained medical staff. Depending on the medication, you will receive treatment every 2, 4, or 8 weeks.
Are there side effects from biologic therapy?
Biologics are generally well-tolerated. The most common side effects are mild and include injection site reactions (redness, swelling, or soreness), headache, fatigue, and joint pain. Serious allergic reactions are rare but possible, which is why biologics are administered in our office where we can monitor you and treat any reactions immediately. Your allergist will discuss all potential risks and benefits before starting treatment.
How long does it take for biologics to work?
Biologic therapy does not provide immediate relief. Most patients begin to notice improvement in asthma symptoms within 4 to 12 weeks of starting treatment, though some may take longer. The full benefits—including reduced exacerbations and improved lung function—often become more apparent after several months of consistent treatment. Patience and adherence to your dosing schedule are essential.
Can I stop using my inhalers once I start biologic therapy?
No. Biologics are add-on therapy, meaning they work alongside your existing asthma medications, not in place of them. You should continue using your inhaled corticosteroids and bronchodilators as prescribed. Over time, as your asthma improves, your allergist may reduce your inhaler doses or adjust your treatment plan—but this should only be done under medical supervision.
How long will I need to stay on biologic therapy?
Biologic therapy is typically a long-term treatment. Many patients remain on biologics for years to maintain asthma control. Your allergist will regularly assess your response to treatment and may adjust or discontinue therapy if your asthma becomes well-controlled or if you no longer meet criteria for continued use. Treatment duration is highly individualized.
Is biologic therapy covered by insurance?
Yes, most insurance plans cover biologic therapy for severe asthma, but prior authorization is typically required. Our team will work with your insurance company to obtain approval and will help you access manufacturer patient assistance programs and co-pay cards to reduce your out-of-pocket costs. The approval process can take several weeks, so we start this early.
Can children receive biologic therapy?
Yes, several biologics are FDA-approved for children as young as 6 years old (and some as young as 12 years old, depending on the specific medication). Biologic therapy can be life-changing for children with severe asthma, reducing exacerbations, improving lung function, and allowing them to participate more fully in school and activities. Your allergist will determine if your child is a candidate.
What happens if I miss a biologic dose?
If you miss a scheduled dose, contact our office as soon as possible to reschedule. Missing doses can reduce the effectiveness of biologic therapy and may lead to a return of asthma symptoms. We will work with you to get back on schedule and minimize any interruption in your treatment.
Can biologics cure my asthma?
No, biologics do not cure asthma. However, they can provide transformative disease control for patients with severe asthma, significantly reducing symptoms, exacerbations, and the need for oral corticosteroids. Many patients are able to achieve and maintain excellent asthma control on biologic therapy, allowing them to live active, fulfilling lives with fewer asthma-related limitations.
