Tetracycline-induced esophageal ulcer: a condition that probably more common than it appears to be

Ten cases of tetracycline derivatives related drug induced esophageal ulceration were described. Five cases were due to minocycline and another five were due to doxycycline. Recumbent posture after drug ingestion was one of the predisposing factors. Odynophagia was the main symptom but may not be the presenting symptom. The diagnosis was easily confirmed by endoscopy. Single-contrast barium study was not sensitive for the demonstration of the esophageal ulcers. The recommended treatment includes cessation of the offending drug and symptomatic treatment. All recovered without any sequela within 3 to 11 days. The most important measure to prevent this condition is to instruct patients to take drugs in the upright position with at least 100 ml of water.
