Modena Allergy + Asthma brings its Eastlake location to Chula Vista's Hale Place medical corridor, where board-certified allergist and immunologist Dr. Brian Modena leads a multi-location practice spanning Southern California with subspecialty focus on food allergies, environmental sensitivities, asthma, and complex immune conditions. Immunotherapy protocols at this site include subcutaneous injection therapy (SCIT), sublingual drops (SLIT), and oral immunotherapy (OIT) for food-allergen desensitization, with maintenance medications dispensed through local pharmacies such as South Bay Pharmacy for antihistamine and corticosteroid refills between injection visits. The Eastlake office treats patients of all ages, providing skin-prick testing panels, serum-specific IgE blood assays, and spirometry-based pulmonary function testing to differentiate allergic asthma from other obstructive airway conditions. Exercise-induced bronchoconstriction and chronic cough cases often benefit from structured pulmonary reconditioning through outpatient rehabilitation providers such as Performance Plus Physical Therapy - Otay Ranch, building respiratory endurance alongside pharmacologic control. The highest-complexity diagnostic workup involves methacholine bronchial challenge testing, which delivers incrementally increasing aerosolized concentrations to quantify airway hyperresponsiveness and confirm an asthma diagnosis when spirometry alone is inconclusive.
