Nifedipine (Procardia XL) as a Cause of False-Positive Results on Barium Enema Study

Authors: DAVID B. GREENSTEIN MD, C MEL WILCOX MD, KENNY FRONTIN MD, JAMES L. CLEMENTS MD

Abstract

ABSTRACT: There are a number of potential causes for false-positive results on a barium enema study. We report three cases in which patients had to have colonoscopy because a nifedipine slow-release tablet (Procardia XL) was misinterpreted as a colonic polyp on a barium enema study. The pill did not move with abdominal compression, further suggesting that it was a polyp. Patients in whom similar lesions are identified during barium enema examination should be questioned as to whether they are taking these medications.
