Content: This will ensure proper treatment if you have a reaction and are unable to verbally alert medical providers of your allergy. The takeaway
Having a sulfa allergy means you have an allergic reaction to medications containing sulfa. While there are many medications that contain sulfa, allergic reactions to sulfa antibiotics are most common. Sulfa allergy and allergy to sulfites found in food or drink aren’t the same thing. Symptoms of an allergic reaction to sulfa drugs include rash or hives, itchy skin or eyes, and swelling. Complications of sulfa allergy include anaphylaxis and Steven-Johnson syndrome. Both of these are considered medical emergencies. Always make sure that your healthcare providers are aware of your sulfa allergy so medications containing sulfa can be avoided. Let your healthcare provider know right away if you suspect a sulfa allergy. Last medically reviewed on December 22, 2017
