Consumer Medicine Information
This leaflet answers some common questions about Chlorsig.
It does not contain all of the available information.
It does not take the place of talking to your doctor, pharmacist or optometrist.
All medicines have risks and benefits. Your doctor, pharmacist or optometrist has weighed the risks of you taking Chlorsig against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor, pharmacist or optometrist.
Keep this leaflet with the medicine. You may need to read it again.
Chlorsig contains chloramphenicol, a synthetic antibiotic, as the active ingredient.
Chlorsig is available as eye drops and eye ointment, 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 Chlorsig has been prescribed for you. They may have prescribed it for another purpose.
Do not use Chlorsig if you are allergic to chloramphenicol or any of the ingredients listed at the end of this leaflet. Some of the symptoms of an allergic reaction to Chlorsig may include irritation, pain and swelling in the eye. Skin rashes, blisters and fever may also occur.
Do not give Chlorsig to children under 2 years of age unless your doctor or optometrist tells you.
Do not use Chlorsig after the expiry date (EXP.) printed on the pack.
Do not use Chlorsig if the packaging is torn, broken or shows signs of tampering.

If you have not told your doctor or optometrist about any of the above, tell them before you use Chlorsig.
Tell your doctor, optometrist or pharmacist if you are using any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop. Some medicines may interfere with Chlorsig. These include other eye drops and eye ointments.
These medicines may reduce or increase the effectiveness of Chlorsig, reduce its own effectiveness and/or react with Chlorsig resulting in untoward or sometimes dangerous side effects.
Your doctor, optometrist or pharmacist has more information on medicines to be careful with or avoid while using this medicine.
Follow all directions given to you by your doctor, optometrist or pharmacist carefully. They may differ from the information contained in this leaflet.
The dose of Chlorsig 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:
Chlorsig eye drops:
For adults and children (2 years and over): Instil 1 or 2 eye drops in the affected eye(s) every two to six hours for up to 5 days or as directed by your doctor, optometrist or pharmacist.
Chlorsig eye ointment:
For adults and children (2 years and over): Apply 1.5 cm of eye ointment every three hours for up to 5 days or as directed by your doctor, optometrist or pharmacist.
If ointment is used together with drops for day and night coverage, eye ointment should be applied before bedtime while using the drops during the day.
If the condition does not get better after 2 days, seek medical advice.
Chlorsig should be used for up to 5 days or as directed by your doctor, optometrist or pharmacist.
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.
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.
