Combination ophthalmic ointment (neomycin/polymyxin B/bacitracin ± hydrocortisone) for bacterial conjunctivitis and ocular surface infections. Multi-component topical ophthalmic ointment: neomycin (aminoglycoside → 30S ribosomal binding → protein synthesis inhibition), polymyxin B (membrane-disrupting polypeptide → gram-negative bactericidal), bacitracin (cell wall synthesis inhibitor → gram-positive bactericidal). ± hydrocortisone (anti-inflammatory). Broad-spectrum gram-positive and gram-negative coverage. Key information Neomycin/polymyxin B/bacitracin ophthalmic. Do not use in corneal ulcer (polymyxin B cytotoxic). For ophthalmic/topical use only. Neomycin allergy possible with prolonged use.

How to Give this Medication

Ophthalmic ointment: Instill into the conjunctival sac; avoid touching dropper tip to eye or periocular tissue. Apply 1 cm ribbon to lower conjunctival sac. Otic: Clean ear canal before instillation. Gently massage base of ear after application to distribute medication. Verify TM integrity. Apply 3–4 times daily. Warm tube in hands before use. Store at room temperature; protect from light. If a dose is missed Apply the missed dose as soon as you remember. If it is almost time for the next application, skip it and resume the normal schedule. Do not apply extra product to compensate.

Side Effects

Ophthalmic: transient stinging upon instillation. Neomycin hypersensitivity: allergic blepharoconjunctivitis (contact allergy — one of most common topical allergens). Ototoxicity with ruptured TM (neomycin component). Petrolatum base may blur vision transiently.

Precautions

For animals Verify tympanic membrane integrity before otic use (neomycin is ototoxic). Neomycin contact allergy can develop — monitor for increased irritation. Avoid in eyes without appropriate ophthalmic formulation. For people handling this medication Wear gloves when handling. Wash hands thoroughly with soap and water after handling. Triple ophthalmic antibiotic — contains neomycin (common allergen). Wear gloves when applying. Avoid human eye contact. Avoid contact with eyes; if contact occurs, flush with water for 15 minutes and seek medical attention.

Contact your veterinarian. Ophthalmic antibiotic combination — systemic toxicity from eye drops is unlikely.
