Learning From History: How to Swallow a Pill

J Clin Psychiatry 2013;74(10):e949-e951

There is evidence that if tablets or capsules are swallowed with little or no water, or if the patient lies down immediately after swallowing the medication, esophageal transit of the medication may be delayed; this can result in an underrecognized condition known as pill esophagitis. This article examines factors that predispose to pill esophagitis, medications that have been associated with pill esophagitis, and strategies to minimize the risk of pill esophagitis in clinical practice. Iron supplementation is used as a case in point because iron, which is known to cause pill esophagitis, may be indicated in different contexts in psychiatric patients.
