Primary Uses at a Glance

Bacterial Conjunctivitis (Pink Eye)

Gentamicin Eye Drops are used to treat bacterial conjunctivitis — an infection of the conjunctiva (the clear membrane lining the white of the eye). This is the most common indication for ophthalmic antibiotic drops. Gentamicin is effective against many Gram-negative and some Gram-positive bacteria that cause conjunctivitis.

As prescribed by your doctor. Standard dose: 1–2 drops every 4–6 hours.

External Ocular Infections Caused by Susceptible Bacteria

Gentamicin Eye Drops are used for external eye infections including blepharitis (eyelid infection), dacryocystitis (tear duct infection), and keratitis (corneal infection) caused by bacteria susceptible to gentamicin. Treatment should be targeted based on culture results where possible.

As prescribed by your doctor — course duration depends on the specific infection.

Post-operative Prophylaxis After Eye Surgery

Gentamicin Eye Drops are used after eye surgery (such as cataract surgery) to prevent post-surgical bacterial infections. The antibiotic drop helps protect the eye from bacterial contamination during the healing period.

As prescribed by your eye surgeon. Follow the specific post-operative schedule.

Frequently Asked Questions

For which conditions are Gentamicin Eye Drops most effective?

Gentamicin Eye Drops are most effective for bacterial conjunctivitis and external ocular infections caused by Gram-negative bacteria. They are not effective against viral or fungal eye infections.

Can Gentamicin Eye Drops be used without a doctor's prescription?

Gentamicin Eye Drops are a prescription medicine. Do not use them without a doctor's advice. Incorrect use can lead to antibiotic resistance and mask other serious eye conditions.

How long do Gentamicin Eye Drops take to show results?

Improvement in bacterial conjunctivitis symptoms is usually seen within 24–48 hours. Continue the full course as prescribed even if symptoms improve earlier to prevent recurrence and resistance.

Can Gentamicin Eye Drops be used long-term?

No. Gentamicin Eye Drops should only be used for the prescribed course (typically 5–7 days). Prolonged use increases the risk of fungal superinfection and bacterial resistance.

What should I do if Gentamicin Eye Drops do not seem to work?

If eye symptoms do not improve within 48 hours of starting treatment, consult your doctor. The infection may be caused by a virus or fungus, or by a bacterium not susceptible to gentamicin.
