Insights

Azithromycin rarely causes hearing loss, usually reversible in immunocompromised patients. This case shows irreversible hearing loss in a healthy woman after low-dose azithromycin exposure.

Area of Science:

  • Ototoxicity research
  • Antibiotic-induced adverse effects
  • Clinical case studies

Background:

  • Azithromycin, an azalide antibiotic, is rarely associated with ototoxicity.
  • Previous reports link azithromycin ototoxicity to prolonged, high-dose therapy in patients with acquired immunodeficiency syndrome (AIDS).
  • Reported cases typically involve reversible sensorineural hearing loss.

Observation:

  • A case of sensorineural hearing loss is presented in an otherwise healthy woman.
  • The patient experienced hearing loss following low-dose azithromycin exposure.
  • This contrasts with previous reports of ototoxicity in patients with specific underlying conditions and higher doses.

Findings:

  • The patient developed irreversible sensorineural hearing loss.
  • This case demonstrates a rare instance of azithromycin-induced ototoxicity.
  • The hearing loss occurred despite low-dose exposure and absence of predisposing conditions.

Implications:

  • Azithromycin ototoxicity may occur in healthy individuals even with low-dose exposure.
  • This finding expands the known risk profile for azithromycin-induced hearing loss.
  • Clinicians should consider azithromycin ototoxicity in patients presenting with sensorineural hearing loss, regardless of dose or underlying health status.
