My doctor just had me get Sucralfate 1GM TAB and told me to take it after I eat. This I understand is for ulcers and as far as I know I don't have ulcers. They say I have Barrett's esophagus and I had the biopsy done and it came back negative for Barretts. The only other things it said was Normal duodenum, erythematous mucosa in the antrum and arytenoid erythema, artenoil edema and intra-arytenoik muscosal thickening were found. So I would like to know what I would have to take this medication?
