Physicians who specialize in allergy and immunology, called allergists/clinical immunologists, are trained in the prevention, diagnosis and treatment of problems involving the immune system. These problems include reactions to usually harmless substances such as food, drugs, chemicals, insect stings and pollens, and allergic conditions such as hay fever, asthma, hives, dermatitis, and eczema. Allergists often are specialists in diagnosis and treatment of other problems of the respiratory system, such as sinusitis, chronic cough, and exercise-induced breathing problems.

Allergists/immunologists are also trained to handle both inherited and acquired immunodeficiency diseases, including agammaglobulinemia, IgA deficiency, and common variable immunodeficiency.

When treating a patient, an allergist/immunologist examines the patient’s background and performs tests to identify the cause of the allergic or immunologic problem. The allergist/ immunologist may then advise the patient to avoid certain substances, prescribe medications for allergy or asthma, or administer immunizing injections, which increase the patient’s tolerance to certain substances and reduce allergic symptoms.

Training for allergists/immunologists includes medical school, followed by three years of postgraduate training in pediatrics or internal medicine, and two or three additional years in allergy and immunology. Thus, allergists/immunologists specialize as pediatricians or internists, and are also trained in allergy and clinical immunology.

Allergists who are asthma specialists may have additional special training in respiratory medicine and pulmonology.
