EVIDENCE-BASED ANSWER Diuretics that do not contain a sulfonamide group eg, amiloride hydrochloride, eplerenone, ethacrynic acid, spironolactone, and triamterene are safe for patients with an allergy to sulfa. The evidence is contradictory as to whether a history of allergy to sulfonamide antibiotics increases the risk of subsequent allergic reactions to commonly used sulfonamide-containing. I can say, however, that I have not had any cross allergic reaction to other drugs sometimes associated with sulfa allergies. Whether you try Plaquenil or not is ultimately up to you and your doctor, but a lot will depend on the type and severity of reactions that you've had.
