Eric Macy, MD is a board-certified allergist and immunologist in Allied Gardens, San Diego, practicing within the Southern California Permanente Medical Group at 4647 Zion Avenue, CA 92120. He completed his medical degree at the University of Southern California School of Medicine in 1984, followed by a fellowship in allergy and immunology at UCLA, and holds dual certification from the American Board of Internal Medicine and the American Board of Allergy and Immunology. Macy is a Fellow of the American Academy of Allergy, Asthma and Immunology and served as chair of its Adverse Reactions to Drugs and Biologicals Committee from 2003 to 2006. Referrals to the allergy department often originate from primary care physicians across the Kaiser network, and Inspire Wellness: Habib Dalhoumi, MD in Grantville is one provider who routes patients presenting with recurrent allergic rhinitis, suspected drug reactions, or uncontrolled asthma to Macy's department. His clinical focus at the Kaiser system includes drug allergy evaluation — particularly penicillin allergy testing using oral amoxicillin challenge protocols — alongside asthma diagnosis with reversible airflow obstruction measurement, chronic urticaria management, environmental allergy immunotherapy, and food allergy workups. His published research in the Journal of Allergy and Clinical Immunology has addressed population-based penicillin allergy prevalence, beta-lactam cross-reactivity, and the clinical consequences of unverified drug allergy labels in electronic health records. He also holds an appointment as assistant clinical professor of medicine at UC San Diego, where he participates in medical student and allergy-immunology fellowship training. The Zion Avenue campus in the 92120 ZIP code provides on-site pulmonary function testing, laboratory services for IgE and tryptase panels, and the Pharmacy at Kaiser Permanente Vandever Medical Offices fills immunotherapy prescriptions and epinephrine auto-injectors within the same Allied Gardens footprint. Macy currently chairs the Southern California Kaiser Permanente Institutional Review Board, overseeing all human-subject research conducted across the region's Kaiser facilities.
