How do you find acceptable medications? I asked my Cardiologist to prescribe a grain-free ace inhibitor and he said he didn’t know which medications would be grain free. If I could provide him with a list of medications that are grain free, he could then select one. I then, asked my druggist if any of my medications had grain in them. The answer was one did. It was Lisinopril. The source of grain was “starch” listed as “other” ingredients. All the ace inhibitors she looked at had the same ingredient. Now what do I do?
