Otolab (Procaine Hydrochloride, Phenazone)

Procaine Hydrochloride, Phenazone, the active ingredients in Otolab, are a local anesthetic and non‑steroidal anti‑inflammatory drug (NSAID) combination presented as a topical otic solution for ear canal use. They provide rapid pain relief and reduce inflammation in acute otitis media and other ear discomforts for adults and children.

GNH USA supplies Otolab as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Otolab combines a local anesthetic and an NSAID to address ear‑related pain and inflammation.

- Acute otitis media: alleviates moderate to severe ear pain while reducing inflammatory swelling. - Otitis externa: eases discomfort and diminishes local inflammation of the external auditory canal. - Post‑operative ear pain: provides short‑term topical anesthesia after ear surgeries. - Ear canal irritation: soothes mild irritation caused by wax removal or minor trauma.

Adverse reactions to Otolab are generally limited to the site of application, but systemic effects can occur.

Common Side Effects: - Local burning or stinging sensation. - Mild itching or erythema of the ear canal. - Transient dizziness or a feeling of fullness. - Temporary alteration of taste.

Serious or Rare Side Effects: - Allergic reaction including angio‑edema or anaphylaxis. - Severe ototoxicity leading to hearing loss. - Persistent ulceration or necrosis of the ear canal skin. - Systemic toxicity such as seizures (rare with excessive absorption). - Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Before using Otolab, consider the following safety measures. - Allergy assessment: avoid if the patient has known hypersensitivity to amide‑type local anesthetics or phenazone. - Tympanic membrane integrity: do not use if there is a perforated eardrum or middle‑ear infection. - Duration of therapy: limit use to the shortest period necessary for symptom control. - Pediatric use: exercise caution in infants and young children; follow prescriber guidance. - Systemic toxicity monitoring: watch for signs of CNS or cardiovascular effects if large amounts are applied. - Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Otolab may interact with other medications; awareness helps prevent adverse outcomes.

Major Interactions (Avoid): - Concurrent use with other topical anesthetics may increase risk of local toxicity. - Co‑administration with systemic anticoagulants or other NSAIDs can heighten bleeding risk.

Moderate Interactions (Monitor Closely): - MAO inhibitors: may potentiate systemic effects of phenazone. - Anticonvulsants: monitor for additive CNS depression if systemic absorption occurs. - Beta‑blockers: may alter cardiovascular response to systemic procaine absorption.
