Otipax (Phenazone, Lidocaine Hydrochloride)

Otipax combines phenazone and lidocaine to address ear‑related discomfort through anti‑inflammatory and local anaesthetic effects.

• Otitis externa: reduces pain and inflammation in the external auditory canal.
• Ear canal irritation: alleviates burning and itching associated with minor trauma or moisture exposure.
• Post‑procedural ear discomfort: provides symptomatic relief after otoscopic examinations or minor ear procedures.

• Phenazone inhibits cyclo‑oxygenase enzymes, decreasing prostaglandin synthesis and thereby reducing inflammation and pain. Lidocaine blocks voltage‑gated sodium channels in peripheral nerves, preventing the initiation and propagation of nerve impulses, which produces local anaesthesia in the ear canal.

Adverse reactions may occur at the application site or systemically after absorption.

Common Side Effects

• Mild burning sensation: temporary discomfort at the site of application.
• Local itching: mild pruritus around the treated area.
• Redness: mild erythema of the ear canal skin.
• Slight swelling: minor oedema localized to the application site.

Serious or Rare Side Effects

• Allergic dermatitis: rash, swelling, or hives indicating hypersensitivity.
• Severe ototoxicity: rare hearing loss or balance disturbances.
• Systemic toxicity: signs such as dizziness, nausea, or cardiac irregularities if excessive absorption occurs.
• Anaphylaxis: acute, life‑threatening allergic reaction requiring immediate medical attention.

When using Otipax, consider the following safety measures:

• Assess for ear perforation: avoid application if the tympanic membrane is ruptured.
• Monitor for hypersensitivity: discontinue if rash or itching develops.
• Use with caution in children: pediatric safety has not been fully established.
• Avoid concurrent otic NSAID products: reduces risk of additive irritation.
• Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Otipax may interact with other medications applied to the ear or systemic drugs that affect bleeding or wound healing.

Major Interactions (Avoid)

• Concurrent otic NSAIDs: increased risk of local irritation and delayed healing.
• Systemic anticoagulants: potential for enhanced bleeding if the tympanic membrane is compromised.

Moderate Interactions (Monitor Closely)

• Topical antibiotics: may alter absorption of lidocaine.
• Ear syrups or drops containing alcohol: increased irritation potential.
