Chest pain from pill-induced esophagitis: A rare side effect of ascorbic acid

Pill-induced esophagitis is a rare cause of acute chest pain. Patients likely to be affected are those with underlying esophageal disorders, those who ingest medications without a sufficient amount of water, or adopt a supine position during or shortly after swallowing medication. Esophagitis secondary to ingestion of ascorbic acid pills is extremely rare. Here, we report a case of ascorbic acid-induced esophagitis in a middle-aged adult, with no known underlying pathological abnormalities of the esophagus. Diagnosis was made based on the history and endoscopic findings. The patient fully recovered and an esophageal ulcer healed after discontinuation of ascorbic acid.
