Topical otic analgesic

Phenazone with lidocaine

Brand names: Otocalm

Phenazone with lidocaine ear drops combine an analgesic and a local anaesthetic for the symptomatic relief of pain in acute otitis media with an intact eardrum.

Dosing — being independently re-sourced

ClinCalc Pro is rebuilding its dose data from primary open sources — the manufacturer SmPC (eMC), the WHO Model Formulary and other official references — under clinician review. This drug's structured dose is not yet published here. Confirm all doses against the product SmPC and your local formulary before prescribing.

Clinical monograph

How it works

Lidocaine blocks neuronal sodium channels to produce local anaesthesia, while phenazone provides additional analgesic and anti-inflammatory action within the ear canal.

Prescribing in practice

  • It must not be used if the tympanic membrane is perforated.
  • It relieves pain only and does not treat the underlying infection, which may still require separate management.
  • Local irritation of the ear canal may occur.

Monitoring

No formal monitoring is required; review if ear pain persists, worsens, or is accompanied by discharge.

Counselling the patient

  • These drops ease pain but do not cure the infection itself.
  • Do not use if you have or suspect a hole in the eardrum.
  • Seek review if pain continues or you notice fluid draining from the ear.

Evidence & guidelines

Use reflects its established role in symptomatic relief of ear pain in otitis media with an intact eardrum; see current prescribing references.

Reference: NICE NG91; Drug verified in RxNorm (NLM); confirm dosing against the manufacturer SPC (eMC). Verify against your local formulary and current prescribing references before prescribing. Monograph status: clinician-reviewed (2026-07-04).
