Content: Treatment
The first-line treatment of a sulfa allergy is the termination of the suspected drug. However, in milder cases where a sulfa drug is considered essential to the treatment of an infection, your doctor and/or allergist may supervise the administration of smaller doses, gradually increasing the dose as tolerated. This is referred to as allergy desensitization. 11 ﻿
Anaphylaxis requires an immediate epinephrine injection to halt the reaction, followed by supportive care and non-inflammatory medications such as corticosteroids. 6 ﻿
SJS and TEN also require emergency medical treatment, including pain medications, corticosteroids, and intravenous hydration. Severe cases often require the care of a burn center. 7 ﻿

Prevention
People with a known sulfa allergy should always check with their doctor before starting a new medication. This is especially true for those who have had a previous severe reaction to sulfa drugs.
