Pil-induced, also called drug-induced, esophagitis can happens when medications are taken incorrectly. If you don’t swallow enough water or lie down right after a dose, the pills can get hung up in your esophagus. The contents leak out and may cause an ulcer and painful symptoms. A Mayo Clinic gastroenterologist explains which medications can cause esophagitis and how to prevent it.
