A doctor has provided 1 answer
Sulfa vs Sulfate : "sulfa allergy" is a term used to describe adverse drug reactions to the antibiotic group sulfonamide, which include septra and bactrim (sulfamethoxazole and trimethoprim). Sulfates and sulfites are commonly used as preservatives in foods. While both sulfonamides and sulfates contain a sulfur molecule, they are chemically different. Having an allergic reaction to sulfonamides is not associated with being allergic to sulfates.
