Gentamicin eye drops are a prescription-only aminoglycoside antibiotic used to treat bacterial eye infections. They work by stopping the growth of bacteria causing conditions like pink eye (conjunctivitis), blepharitis, and corneal ulcers.
Key Medical Facts & Uses
-
Approved Conditions: Prescribed for superficial ocular infections including bacterial conjunctivitis, keratitis, and eyelid inflammation.
-
Infection Specificity: It only clears bacterial infections. It will not work for viral infections (like standard viral pink eye) or fungal eye issues.
-
Brand Names: Commonly marketed under names like Garamycin, Genoptic, and Gentak.
Standard Dosage and Administration
Always follow the specific instructions on your prescription label.
-
Mild to Moderate Infections: 1 to 2 drops every 4 hours.
-
Severe Infections: Up to 2 drops every hour as directed by your doctor.
-
Duration: Typically used for 5 to 10 days. You must finish the entire course even if your symptoms improve early.
Crucial Usage Precautions
-
Contact Lenses: Do not wear contact lenses while treating an active eye infection. “Contact lenses should be removed when treating an eye infection with these drops.”
-
Contamination Risk: Never let the dropper tip touch your eye, fingers, or any surface.
-
Other Eye Medications: If you use multiple eye drops, wait at least 5 to 10 minutes between applying each medication.
-
Nasolacrimal Occlusion: After putting in a drop, close your eye and gently press the inner corner near your nose for 1 to 2 minutes. This keeps the medicine inside your eye and lowers systemic absorption.
Side Effects & Risks
-
Common: Temporary stinging, burning, redness, or brief blurred vision right after application.
-
Prolonged Use Risks: Using topical antibiotics too long can cause a secondary fungal infection or bacterial resistance.
-
When to call a doctor: Stop use and seek immediate care if you experience severe allergic reactions, worsening eye pain, swelling, or heavy pus discharge.
