Gentamicin eye drops

About gentamicin eye drops

What are gentamicin eye drops used for?

Gentamicin eye drops are used to treat bacterial infections of the eyes or eyelids such as conjunctivitis. The drops kill germs (bacteria) which are the cause of infection. Eye infections are a common cause of conjunctivitis. In conjunctivitis, your eye becomes inflamed, feels gritty, and may water more than usual.

Gentamicin eye drops are also prescribed for minor eye injuries, such as scratches and abrasions to the cornea - the delicate layer covering the surface of your eye. In such cases, the drops are prescribed to prevent an eye infection from developing while the eye heals.

Who should not use gentamicin eye drops?

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start using gentamicin drops it is important that your doctor knows:

• If you are pregnant or breastfeeding.

• If you have ever had an allergic reaction to gentamicin or to any other antibiotic, or to any other eye drops.

• If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

How to use gentamicin eye drops

Read the leaflet in the pack before using gentamicin eye drops. It explains how to use it and lists possible side effects.

If your eyes have an obvious discharge or 'crust', it can help if you bathe them with cool clean water before using the gentamicin drops.

1. Wash your hands before you use the drops.

2. Remove the cap from the bottle.

3. Tilt your head back a little and gently pull the lower lid of your eye out to form a pocket.

4. Hold the bottle upside down near to your eye. Try not to touch your eye as you do this.

5. Gently squeeze the bottle to release one drop into your eye. Only use a second drop if the first drop missed going into your eye.

6. Close your eye for a minute or two, and press gently on the side of your nose where the corner of your eye meets your nose. This helps to stop the drop from draining away and keeps it in your eye.

7. Repeat the process in your other eye if you have been told to use the drops in both eyes.

8. Replace the cap.
   

Getting the most from your treatment

• Take gentamicin eye drops exactly as your doctor tells you to and always check the label for the correct usage.

  • It is usually 3-4 times a day but may be more frequently, particularly on the first day.

• Try not to miss any doses. If you forget to put the drops in on time, do it as soon as you remember.

• Your eye should feel better in a few days, but keep using gentamicin for 48 hours after it looks normal to make sure all the bacteria are gone.

• The drops may blur your vision for a short time. Wait until you can see clearly before driving or using machines.

• To prevent spreading the infection, wash your hands often, avoid touching your eyes, and don’t share towels or pillows.

• If the tip of the bottle touches your eye(s) when putting the drops in, it is a good idea to squeeze out two or three drops straightaway on to some tissue and rinse the tip with salt water.

• Eye infections can cause your eyes to become more sensitive to sunlight than usual. Wearing sunglasses may help to prevent this.

• If using other eye drops, wait at least 5 minutes between each one so your eye can absorb them properly.

• If your symptoms get worse while using gentamicin drops, see your doctor immediately, especially if your eye is painful, sensitive to light, or your vision changes.

• Do not wear contact lenses until your symptoms have completely gone. Wait for 24 hours after the last dose of eye drops before using your lenses again.

How to store gentamicin eye drops

• Keep all medicines out of the reach and sight of children.

• Store in a cool, dry place, away from direct heat and light.

• Throw away the bottle of eye drops after you have finished your course of treatment, even if there is some liquid left.

• Do not keep opened bottles to use later, as eye drops must not be used if the bottle has been opened for longer than four weeks.
