Clinical monograph

How it works

It acts as an astringent, precipitating surface proteins to reduce inflammation, exudation and create an unfavourable environment for microbial growth.

Prescribing in practice

  • It is for topical aural use only and the ear canal should be inspected to confirm an intact tympanic membrane before instillation where possible.
  • Application is often via a medicated wick inserted by a clinician in marked canal oedema.
  • Treatment is intended to be short-term while inflammation settles.

Monitoring

Review the ear canal clinically for resolution of inflammation and discharge during treatment.

Counselling the patient

  • Use only in the affected ear as directed.
  • Keep the ear dry and avoid inserting cotton buds.
  • Return if symptoms worsen or fail to improve.
