Otalgan (Procaine Hydrochloride, Phenazone)

Procaine hydrochloride, the active ingredient in Otalgan, is a local anesthetic and non‑steroidal anti‑inflammatory drug (NSAID) presented as a combination formulation for otic use. It is used to relieve pain and inflammation in the ear, particularly in conditions such as otitis media and external ear irritation.

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

Otalgan combines a local anesthetic and an NSAID to address ear‑related pain and inflammation. It is indicated for several ear conditions where both analgesia and anti‑inflammatory action are needed. - Otitis media: reduces pain and inflammation in the middle ear. - Otitis externa: alleviates discomfort and swelling of the external auditory canal. - Post‑procedural ear pain: provides symptomatic relief after ear examinations or minor surgical interventions.

Adverse reactions may occur following otic administration of Otalgan. Monitoring for both common and less frequent events is recommended.

Common Side Effects: - Ear itching: mild pruritus in the treated ear. - Ear fullness: sensation of blockage or pressure. - Temporary hearing change: mild, reversible alteration in hearing acuity. - Local redness: mild erythema of the ear canal skin.

Serious or Rare Side Effects: - Allergic reaction: rash, swelling, or hives indicating hypersensitivity. - Otitis media exacerbation: worsening infection symptoms. - Persistent vertigo: ongoing dizziness after application. - Severe ototoxicity: rare loss of hearing requiring medical assessment.

When using Otalgan, consider the following safety measures to minimize risks and ensure effective therapy. - Contraindication: avoid use in patients with known hypersensitivity to procaine, phenazone or any formulation excipients. - Ear integrity: do not apply if the tympanic membrane is perforated unless specifically directed by a clinician. - Pediatric use: exercise caution and follow professional guidance for children. - Concomitant otic medications: assess potential additive effects before combining with other ear drops. - Pregnancy and lactation: use only if the benefit outweighs potential risk, under medical supervision. - Store at ambient temperature: keep below 25°C, protect from moisture and light in the original container.

Otalgan may interact with other medicines applied to the ear or systemic agents that affect bleeding or hypersensitivity.

Major Interactions (Avoid): - Systemic NSAIDs: concurrent use may increase risk of gastrointestinal bleeding. - Aminoglycoside ear drops: combined ototoxic potential.

Moderate Interactions (Monitor Closely): - Anticoagulants: monitor for any signs of otic bleeding. - Other local anesthetics: cumulative nerve‑blocking effect may enhance local anesthesia. - Corticosteroid ear preparations: assess for altered drug absorption. - Alcohol: may increase systemic exposure to phenazone metabolites.
