Type 2 Inflammation Biologic (Anti-IL-4/IL-13) from Sanofi / Regeneron.
Dupixent has the broadest set of FDA-approved indications of any Type 2 biologic — covering asthma, atopic dermatitis, nasal polyps, eosinophilic esophagitis, prurigo nodularis, and COPD. By blocking the IL-4 and IL-13 pathways central to Type 2 inflammation, it can address multiple coexisting conditions with a single therapy.
Dupixent is FDA-approved for the following indications:
Dupixent is administered subcutaneously every two weeks via self-injection at home. Patients are trained on technique and many use auto-injector formulations for convenience.
The manufacturer offers a patient support program — Dupixent MyWay Patient Support — that can help with insurance navigation, copay assistance for eligible patients, nursing support, and ongoing education. More information is available at https://www.dupixent.com/support-savings/myway.
Treatment with Dupixent is initiated and monitored by Dr. McNeil. Prior authorizations are handled in-house — patients are not asked to navigate insurance approvals on their own. This is a subcutaneous self-administered medication. After prior authorization, the prescription is sent to a specialty pharmacy that ships the medication directly to the patient. A manufacturer-sponsored nurse or office-based training visit is typically arranged for the first dose so patients are confident with self-administration before continuing at home.
