After Domagk published his findings in 1935, doctors found that Prontosil could control many bacterial infections.

Patients who are allergic to sulfa and require a diuretic (âwaterâ) pill have several options. In general, the sulfa contained in antibiotic drugs has a slightly different chemical structure than the sulfa compounds found in diuretics. As a result, people who are allergic to sulfa antibiotics may be able to take a sulfa-containing diuretic without experiencing a reaction. For patients who are allergic to sulfa-containing diuretics, doctors sometimes prescribe triamterene, spironolactone, amiloride, or ethacrynic acid.
