1. WHAT CHLORMYTOL OINTMENT IS AND WHAT THEY IT IS USED FOR
Chlormytol Ointment is a topical ointment for administration to the eye only, it contains an
antibiotic called chloramphenicol. When chloramphenicol is given in eye ointment, it is used to
treat bacterial infections that affect the outer surfaces of the eye.
The most common type of infection in this area is called acute bacterial conjunctivitis. When you
have acute bacterial conjunctivitis the white part of one or both of your eyes will be red and /or
your eyelids will be red or swollen. There will be a sticky discharge, which can make the eye
difficult to open in the morning and the eye may feel ‘gritty’ or ‘irritated’.
Chlormytol Ointment can be used in adults and children over 2 years. Chloramphenicol eye
ointment is not suitable for treating eye infections that have spread to the deeper layers of the eye
coverings or into the fluid within the eyeball. Antibiotic tablets or injections are needed to treat
these deeper and more serious infections.
You must talk to a doctor if you do not feel better or if you feel worse after 2 days.
