Patient Education

The Division of Allergy & Immunology at UTMB places an emphasis on education that is directed toward patients and the public as well as future allergy-immunology caregivers.

Patient-Oriented Education
Sufferers of moderate to severe asthma can provide countless stories of trips to emergency rooms. Management of asthma has historically been to provide an intervention to someone having a respiratory attack. The physicians at UTMB are changing this paradigm.

In addition to providing information related to how to take current medications and what to do in the event of an attack, the physicians at UTMB are teaching their patients how to monitor and manage their respiratory health to prevent them from ever having to present at an emergency room. This same approach is extended to the management and education of all patients treated by the Division.
