Gentamicin is an aminoglycoside that targets Gram‑negative and some Gram‑positive bacteria in ocular infections.

- Bacterial conjunctivitis: reduces bacterial load and accelerates symptom relief. - Bacterial keratitis: helps eradicate the infecting organism and prevents corneal scarring. - Post‑operative ocular prophylaxis: lowers the risk of infection after eye surgery.

Gentamicin ophthalmic solution may cause local and systemic adverse reactions.

Common Side Effects: - Eye irritation: transient burning or stinging sensation. - Redness: mild conjunctival hyperemia. - Tearing: increased lacrimation. - Foreign‑body sensation: feeling of grit in the eye. - Blurred vision: temporary visual disturbance.

Serious or Rare Side Effects: - Corneal ulceration: breakdown of corneal epithelium. - Hypersensitivity reaction: eyelid edema, rash, or pruritus. - Ototoxicity: rare systemic absorption leading to hearing changes. - Nephrotoxicity: rare systemic effect with prolonged use. - Anaphylaxis: severe allergic response requiring immediate medical attention.

Gentamicin ophthalmic solution should be used with caution in specific clinical situations.

- Renal impairment: monitor for systemic absorption in prolonged therapy. - Auditory dysfunction: avoid prolonged use in patients with pre‑existing hearing loss. - Pregnancy: use only if clearly needed; weigh maternal benefit against potential fetal risk. - Pediatric use: limit duration in infants and young children. - Contact lens wearers: remove lenses before instillation and wait before reinserting. - Store at ambient temperature: keep in original container, protect from light and moisture.

Gentamicin may interact with other medicines, altering efficacy or safety.

Major Interactions (Avoid): - Loop diuretics: increase risk of nephrotoxicity. - Other aminoglycosides: additive ototoxic and nephrotoxic effects. - Neuromuscular blocking agents: may potentiate neuromuscular blockade.

Moderate Interactions (Monitor Closely): - Vancomycin: combined use may increase renal toxicity. - NSAIDs: concurrent use may heighten nephrotoxic potential. - Radiographic contrast agents: monitor kidney function when used together.
