What GENOPTIC® eye drops are used for

GENOPTIC® eye drops are used for the treatment of infections of the eye caused by bacteria. These include conjunctivitis (an infection of the transparent skin that covers the inner surface of the eyelid and the surface of the eye which causes the eye to produce discharge, to be itchy and to form crusty eyelids); infection of the cornea (the front layer of the eyeball); corneal ulcers; infection of the edges of the eyelids including hair follicles and glands; infection of the oil producing gland that covers the inner surface of the eyelid and infection of the tear sac.

Mechanism of action:

The active ingredient in GENOPTIC® eye drops, gentamicin sulfate, belongs to a chemical group called the aminoglycosides which have an antibiotic activity against a wide range of bacteria.

Your doctor may have prescribed GENOPTIC® eye drops for another reason. Ask your doctor if you have any questions about why GENOPTIC® eye drops have been prescribed for you.

How to use GENOPTIC® eye drops

How much to use

The usual dosage of GENOPTIC® eye drops is one or two drops in the affected eye(s) every four hours. If you have a serious infection, your doctor may increase the dosage to a maximum of two drops once every hour.

Your doctor will tell you how many drops you need to use each day. Use GENOPTIC® eye drops only as prescribed by your doctor.

Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

Use GENOPTIC® eye drops every day, at about the same time each day, unless your doctor tells you otherwise. Using your eye drops at the same time each day will have the best effect on your condition. It will also help you remember when to use the eye drops.

If you are being changed from one eye drop to another, follow your doctor’s instructions carefully as to when to stop the old drops and when to start the new drops.

How to use it

You may find it easier to put drops in your eye while you are sitting or lying down.

If you are wearing soft contact lenses, remove them before putting the drops in your eye.

To open a new bottle of GENOPTIC® eye drops, first tear off the protective seal from the bottle. The seal will break and you can pull it off and then throw it away.

  1. Wash your hands well with soap and water.
  2. Shake the bottle gently.
  3. Remove the cap.
  4. Hold the bottle upside down in one hand between your thumb and forefinger or index finger.
  5. Using your other hand, gently pull down your lower eyelid to form a pouch or pocket.
  6. Tilt your head back and look up.
  7. Put the tip of the bottle close to your lower eyelid. Do not let it touch your eye.
  8. Release one drop into the pouch or pocket formed between your eye and eyelid by gently squeezing the bottle.
  9. Close your eye. Do not blink or rub your eye.
  10. While your eye is closed, place your index finger against the inside corner of your eye and press against your nose for about two minutes. This will help to stop the medicine from draining through the tear duct to the nose and throat, from where it can be absorbed into other parts of your body. Ask your doctor for more specific instructions on this technique.
  11. Replace the cap, sealing it tightly.
  12. Wash your hands again with soap and water to remove any residue.

Wait 15 minutes before replacing your contact lenses.

Be careful not to touch the dropper tip against your eye, eyelid or anything else to avoid contaminating the eye drops.

Contaminated eye drops may give you an eye infection.

How long to use it

Continue using GENOPTIC® eye drops for as long as your doctor prescribes.

If you forget to use it

If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to. Otherwise, use the drops as soon as you remember, and then go back to using/taking them as you would normally.

If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

Do not use double the amount to make up for the dose that you missed.

If you use too much (overdose)

If you accidentally put several drops in your eye(s), immediately rinse your eye(s) with warm water.

If you think that you or anyone else may have swallowed any or all of the contents of a bottle of GENOPTIC® eye drops, immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to casualty at your nearest hospital. In New Zealand call the National Poisons Information Centre (telephone 0800 POISON or 0800 764 766).

Do this even if there are no signs of discomfort or poisoning.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using GENOPTIC® eye drops. GENOPTIC® eye drops help most people with infections of the eye, but it may have unwanted side effects in a few people.

After using GENOPTIC® eye drops


Keep your eye drops in a cool place where the temperature stays below 25°C. Do not freeze the eye drops.

Do not store it or any other medicine in the bathroom or near a sink. Do not leave it in the car or on window sills. Do not carry the eye drops in the pockets of your clothes. Heat and dampness can destroy some medicines.

Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Do not leave the top/lid off the bottle for any length of time to avoid contaminating the eye drops.


Write the date on the bottle when you open the eye drops and throw out any remaining solution after four weeks.

Eye drops contain a preservative which helps prevent germs growing in the solution for the first four weeks after opening the bottle. After this time there is a greater risk that the drops may become contaminated and cause an eye infection. A new bottle should be opened.

If your doctor tells you to stop using the eye drops or they have passed their expiry date, ask your pharmacist what to do with any remaining solution.
