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.
