What this medicine is used for

How to use this medicine
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
How much to use
Place one or two drops in the affected eye(s) every 2 to 6 hours for 2 to 3 days.
The interval between doses may then be increased.
How to use it
To keep the medicine as germ free as possible, do not touch the tip of the bottle
to the eye or any surface.
Wash your hands.
Tilt your head back and pull the lower lid away from your eye to make a pouch and
drop the medicine into this space. Let go of your eyelid and gently close your eyes.
Try not to blink for a short time as this can stop the medication from working properly.
Apply gentle pressure to the inner corner of the eye (the tear duct) for approximately
1 minute immediately after placing the drops in the eye. This will reduce the amount
of medicine absorbed into the blood stream or other parts of the body.
Keep your eyes closed for 1 to 2 minutes to allow the medicine to come into contact
with the infection.
When to use it
Use this medicine at about the same time each day.
Using it at the same time each day will have the best effect and will also help you
remember when to use it.

Normally treatment is continued for at least 2 days after the eye appears to be back
to normal. Do not use for more than 5 days in total except on medical advice.
If you forget to use it
If it is almost time to administer your next dose, skip the missed dose and use your
medicine at the usual time.
Otherwise, use it as soon as you remember and then go back to using your medicine
as you would normally.
Do not administer a double dose to make up for missed doses.
This may increase the chance of you experiencing side effects.
If you have trouble remembering to use your medicine, ask your pharmacist for some
hints to help you remember.
If you use too much (overdose)
