Content: It is vital to treat the symptoms of anaphylaxis or Stevens-Johnson syndrome as medical emergencies when they occur. An anaphylactic reaction usually requires administration of epinephrine. People with Stevens-Johnson syndrome usually need to spend time in an intensive care unit for treatment that includes: corticosteroids to help control inflammation
antibiotics to help prevent or control skin infections
intravenous (IV) immunoglobulins to stop the disease progressing further
An individual should stop using the drug immediately and seek urgent advice from their doctor if they have an allergic reaction to sulfa medications. Doctors, dentists, and pharmacist should be aware of an individual’s drug allergies to ensure they prescribe the correct medications. Carrying a medical alert card or medical alert bracelet that details any allergies will help to ensure appropriate treatment, as the person may not be able to communicate this themselves in an emergency. Outlook
Many medications contain sulfa, but allergic reactions to sulfa drugs are rare. If a person with a sulfa allergy comes into contact with drugs containing the compound, they may experience a rash or hives, itchy skin or eyes, and swelling. Some people can also experience more severe reactions, such as anaphylaxis and Steven-Johnson syndrome. These are medical emergencies.
