1. WHAT CHOLFEN EYE DROPS IS USED FOR
Cholfen Eye Drops contains chloramphenicol, a synthetic antibiotic, as the active ingredient.
Cholfen Eye Drops is available as eye drops, for external use only.
It is used to treat an eye infection called bacterial conjunctivitis, which is a bacterial infection involving the mucous membrane of the surface of the eye.
The most common symptom is the presence of a sticky yellow-white discharge with mucus and pus (or glued eyes, especially in the morning on waking). Other symptoms include a gritty sensation in the eye, redness, irritation and watering of the eyes. The infection usually starts in one eye and then spreads to the other.
Ask your doctor, pharmacist or optometrist if you have any questions about why Cholfen Eye Drops has been prescribed for you. They may have prescribed it for another purpose.

4. HOW TO USE IT
Follow all directions given to you by your doctor, optometrist or pharmacist carefully. They may differ from the information contained in this leaflet.
How much to use
The dose of Cholfen Eye Drops may be different for each person and their medical condition. Your doctor, optometrist or pharmacist will recommend the right dose for you.
Do not use in children under 2 years of age except on doctor’s advice.
The usual recommended doses are:
Cholfen Eye Drops:
For adults and children (2 years and over): Instill 1 or 2 drops in the affected eye(s) every two to six hours for 2 to 3 days. The interval between applications may then be increased. Treatment should be continued for at least 48 hours after the eye appears normal. Do not use for more than 5 days in total except on medical advice.
If the condition worsens or does not get better after 2 days, seek immediate medical advice.
How to apply Cholfen Eye Drops:
- wash hands thoroughly before and after use
- open the eye, tilt head back and look upwards
- gently pull down the lower lid to form a pouch
- approach the eye from the side and hold the bottle dropper near the lid, but do not let the tip of the dropper touch the eye, eyelids or lashes
- apply one drop into the pouch
- close the eyes (do not rub them) and try not to blink for a short time
- apply gentle pressure for about one minute with a finger to the bridge of the nose to prevent the medicine being drained from the eye
- blot excess solution around the eye with a tissue
- if instilling more than one drop in an eye, separate each installation by several minutes to avoid washing drops out of the eye
- To minimise contamination, do not allow the dropper to contact the surface of the eye.
How long to use it
Cholfen Eye Drops should not be used for more than 5 days except on medical advice.
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 next due.
Otherwise, use it as soon as you remember, and then go back to using it as you would normally.
If you are unsure about whether to use your next dose, speak to your doctor, optometrist or pharmacist.
Do not try to make up for missed doses by using more than one dose at a time. This may increase the chance of you getting an unwanted side effect.
If you use too much (overdose):
Accidental ingestion of the drug in adults is unlikely to cause any toxicity due to the low content of antibiotic, but consult your doctor or Poison Information Centre (see below).
If the eye drops are accidentally ingested by infants or young children, immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital. Do this even if there are no signs of discomfort or poisoning.
Urgent medical attention may be needed.
