Methadone, another cause of opioid-associated hearing loss: a case report.

BACKGROUND

Methadone has been used for many years in the clinical setting and has many well-described side effects. In recent years, the use of methadone and other opioids have been increasing throughout the United States (US), and presentations to US Emergency Departments (EDs) due to opioid use and abuse are increasing as well.

OBJECTIVES

As methadone and opioid use increases, ED physicians should be aware of infrequently seen side effects and toxicities associated with the use of these drugs.

CASE REPORT

We report the case of a previously healthy 20-year-old man who presented with acute onset of bilateral hearing loss secondary to an unintentional methadone overdose. At follow-up, the patient's hearing had returned to normal, with the only intervention being abstinence from methadone.

CONCLUSION

Although bilateral hearing loss is a rare toxic finding of opioid ingestion, given the prevalence of opioid use, this etiology should be considered in any patient presenting with this chief complaint.
