About Gentamicin

Gentamicin is an aqueous solution used as eye drops. The active ingredient gentamicin is an antibiotic. Gentamicin is used in adults and children to kill bacteria which cause infection. It is used for the management of infection in injured eyes, which causes symptoms such as:

  • Red eye.
  • Itching or burning sensation in the eye.
  • Discharge from the eye (pus).

Gentamicin kills the bacteria causing the infection, which eliminates the symptoms. This medicine is not effective for the treatment of non-bacterial eye infections or viral and fungal eye infections.

How to use Gentamicin

Always use Gentamicin exactly as your doctor or pharmacist has told you. The general instructions for use are:

· Pull the lower eyelid gently downwards, hold the bottle upside down above the eye and gently squeeze the bottle to release a drop into your eye.

· Avoid touching the eye (or any other surface) with the tip of the bottle.

· Replace and tighten the cap immediately after use.

· Keep the affected eye closed and press your fingertip against the inside corner of the closed eye, and hold for one minute. This helps to stop the liquid from draining away and keeps it in your eye.

· Remove contact lenses before using the drops. If you wear soft contact lenses, don’t wear them at all until the course of drops has finished. The eye drops may discolour or damage soft lenses. Hard lenses can be worn with the drops; However, you should wait at least 30 minutes after using the drops before putting your contact lenses back in.

· Do not use the eye drops after four weeks of opening. Any medicine remaining in the bottle should be disposed of four weeks after the first opening.


Dosage varies per person and is determined by a doctor for each specific patient depending on the symptoms. The general dosage guidelines are as follows:

  • Adults and children: One drop in the affected eye, four to six times a day. For more severe infections your doctor may tell you to use the drops every one to two hours.

A course of treatment typically lasts two up to three weeks. For more information on dosage, see the package leaflet.


This medicine does not interact with alcohol.

The eye drops may cause your vision to blur temporarily after you have applied them into your eye. Do not drive if you experience this side effect.

If you use too much/forget to use/stop using Gentamicin

If you use more Gentamicin than you were told to, consult your doctor or pharmacist.

If you forget to use Gentamicin, do not take a double dose to make up for a forgotten one. Just shorten the intervals between doses until you are back to your regular dosing schedule.

Do not stop using Gentamicin without consulting a doctor first.
