If allergic to sulfa can one take quinine sulfate?

Sulfa (sometimes spelled sulpha) is an abbreviated word for a group of antibiotic drugs called sulfonomides (or sulphonomides). Sulfonomides are in no way chemically related to sulfer or sulfer salts, sulfates or sulfites and therefore sulfates/sulfites/sulfer do not cause the same hypersensitivity reactions that sulfonomides (sulfas) do. If you are allergic to sulfa, it is ok to take sulfates/sulfites (sulphates/sulphites) because they are not chemically related.
