# Biologic Medications (BiologicMeds.org)

> BiologicMeds.org is a patient education resource produced by Allergy & Asthma Network that provides accurate, accessible information about biologic medications used to treat severe allergic and inflammatory conditions. The site helps patients and caregivers understand what biologics are, how they work, which conditions they treat, and how they differ from traditional medications and biosimilars. It does not provide individualized medical advice, and patients should consult their healthcare provider before making treatment decisions.

Biologic medications are advanced, targeted therapies derived from living cells that work by blocking specific proteins or pathways driving inflammation. They are typically used when standard treatments — such as inhaled corticosteroids, antihistamines, or oral steroids — do not provide adequate control. Conditions covered on this site include severe asthma, eosinophilic asthma, COPD with an eosinophilic phenotype, atopic dermatitis (eczema), chronic urticaria (hives), food allergies, chronic rhinosinusitis with nasal polyps (CRSwNP), aspirin-exacerbated respiratory disease (AERD), eosinophilic esophagitis (EoE), and eosinophilic granulomatosis with polyangiitis (EGPA). Approved biologics covered include Dupixent, Ebglyss, Fasenra, Nemluvio, Nucala, Cinqair, Tezspire, Adbry, and Xolair.
