I have developed an allergy to sulphur. I was taking Edecrin, but the mfg of it has quit making it. My heart doctor tells me I have high pressure in my heart and need a diuretic.
A diuretic that does not contain a sulfonamide group can be used safely in someone with a sulfa allergy. In addition to ethacrynic acid (Edecrin) these include amiloride, triamterene, spironolactone, and eplernone. It is also unclear whether or not there is significant cross-reactivity, between someone with an allergy to a sulfa antibiotic and a sulfa diuretic, so other medications may be safe as well. Talk the options over with your doctor.
