Iron Pill-Induced Chemical Laryngitis

To discuss the presentation and management of pill-induced chemical laryngitis by illustrating a rare case.

We report a unique case of a patient with iron pill-induced laryngitis.

A 71-year-old male presented for evaluation of dysphonia. Five weeks prior, the patient had reportedly aspirated an iron pill. The pill was lodged in his throat for several hours before being coughed up, soft but still intact. Since that event, the patient noted complete voice loss and in clinic was found to have a very breathy and asthenic voice. Stroboscopy revealed aperiodicity with severe false fold compression and significant ulceration of the infraglottic region associated with thick exudate. Vocal folds were mobile but atrophic, with overlying crusted secretions. A sensory deficit was suspected based on scope tolerance. The patient was treated with nebulized ciprodex and humidified air with some improvement in mucosal crusting but had persistent glottic insufficiency and dysphonia, prompting bilateral hyaluronic acid injection.

Pill-induced laryngitis is an extremely rare phenomenon. While typically associated with bisphosphonates, this condition should be considered in any patient presenting with dysphonia and history of aspiration of a pill, including iron supplements. Regardless of the inciting medication, pill-induced laryngitis may be treated with humidified air, nebulized steroids, and antibiotics. Injection augmentation of the vocal folds may be made considered when glottic insufficiency and weak cough contribute to the presentation.
