1. What Chloromycetin Redidrops are and what they are used for
Chloramphenicol belongs to a group of medicines called antibiotics. Chloromycetin Redidrops are
used for the treatment of bacterial conjunctivitis (infection of the eye) in adults and children. The
infected eye will probably be red, gritty or itchy.
In the morning there will be a sticky discharge which may make it difficult to open the eye. When put
in the eye, chloramphenicol works by helping kill the bacteria (germs) and allow the body to
overcome the infection.
You must talk to a doctor if you do not feel better or if you feel worse after 2 days.
