Drug allergy is an inflammatory reaction of the body to an ingested drug, applied topically or inhaled.
An allergist is a doctor specialized in the prevention, diagnosis and treatment of allergic diseases. It performs tests to identify the specific allergens causing reactions and offers personalized treatments, such as antihistamines, corticosteroids, and immunotherapy. It is advisable to see an allergist if persistent symptoms such as sneezing, nasal congestion, difficulty breathing, skin rashes, itching or adverse reactions to foods, medications or insect bites occur.
Remember that for the proper selection of health professional that treats drug allergy you must consider the nature, severity and symptoms you are presenting.
