Biologic Injections in Chicago
Novel approaches to management of hives, eczema, asthma, nasal polyps and an ever-expanding array of other allergic conditions include therapies targeting key cells and mediators driving the inflammatory responses. These therapies, called biologics, are subcutaneous injections that are administered between every two and eight weeks in office or at home.
Some examples include:
- Xolair (omalizumab)
- Fasenra (benralizumab)
- Dupixent (dupilumab)
- Nucala (mepolizumab)
- Tezspire (tezepelumab-ekko)
An allergist can help you determine the right biologic to relieve your hives, eczema, asthma, nasal polyps, and more.
What Are Biologics?
Biologics are targeted medications that block specific parts of the immune system responsible for allergic and eosinophilic inflammation. Unlike traditional medications that treat symptoms broadly, a biologic works on a precise pathway, such as IgE, IL-5, IL-4/IL-13 or TSLP, to reduce flare-ups and improve long-term control.
Conditions Biologic Injections May Treat
- Moderate to severe asthma, including allergic and eosinophilic asthma
- Chronic hives (chronic spontaneous urticaria) that does not respond to antihistamines
- Moderate to severe eczema (atopic dermatitis)
- Chronic rhinosinusitis with nasal polyps – see our sinus disease care
- Eosinophilic esophagitis (EoE) and other eosinophilic conditions
- Food allergy – certain biologics may lower the risk of reactions from accidental exposure in eligible patients
Who Is a Good Candidate?
Biologics are generally considered when symptoms stay uncontrolled despite standard treatment, when patients need frequent oral steroids, or when flare-ups disrupt work, school or sleep. Our Chicago allergists review your history, spirometry results, allergy testing and, when needed, blood work to determine whether a biologic is appropriate and which one fits your condition.
What to Expect
Biologics are given as a small injection under the skin, typically every two to eight weeks depending on the medication. Initial doses are usually given in our office so you can be monitored, and many patients later transition to at-home injections. Our team also helps with insurance and prior authorization requirements, which are common for these therapies.
