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.

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.

Chlorsig should be used for up to 5 days or as directed by your doctor, optometrist or pharmacist.

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.
