1. What Chloramphenicol 0.5% w/v Antibiotic Eye Drops is and what it is used for
Chloramphenicol belongs to a group of medicines called antibiotics. Antibiotics are used for
infections caused by bacteria.
Chloramphenicol 0.5% w/v Antibiotic Eye Drops are for simple eye infections called “acute
bacterial conjunctivitis”. This is sometimes known as “red eye” because the white part of the
affected eye(s) will be red and/or the eyelid(s) will be red or swollen. There may also be a sticky
discharge which can make the eye difficult to open in the morning, and the eye may feel ‘gritty’
or ‘irritated’.

problems can include a severe reduction in red blood cells or lower than normal blood count.
