I had stomach pain, pain in chest, tightness in throat, then horrible rash. After a month on prednisone I started breaking out as I decreased the dosage. I told my doctor I thought it was the Lisinopril and I stopped taking it. I'm feeling better now after being off of it for a week, but still not 100% o.k. I talked to the pharmacist and she said, "You must be allergic to sulfa". I am very allergic to it and have always listed this on the forms in the doctors' offices. Apparently there is some relation between lisinopril and sulfa.
