Although Persulfate contains sulfar which may cause an allergic reaction this is different from the Sulfa drug allergy which contains sulfonamides. That is why Sulfa drug allergy has no connection to Persulfate allergy.

Hope I have answered your query. Let me know if I can assist you further.

Take care
