What is Chloramphenicol Eye Ointment?

Chloramphenicol is a topical antibiotic ointment that treats a range of bacterial infections affecting the eye. It is typically reserved for specific types of infections such as bacterial conjunctivitis. This medication can be prescribed for both cats and dogs.

How does it work?

As a broad-spectrum antibiotic, Chloramphenicol offers rapid clinical relief and is effective against various susceptible gram-positive and gram-negative organisms. Chloramphenicol functions by hindering the production of crucial proteins within these susceptible bacteria, stopping them from reproducing and spreading, managing the infection.

Dose and Administration

Prior to applying Chloramphenicol, it's essential to clean the area surrounding the eye to eliminate any discharge or crusts. Generally, Chloramphenicol is administered every three hours, or as directed by your veterinarian, during the initial 48-hour period.

When applying, place a small amount of the ointment in the lower conjunctival sac of your pet's eye. The treatment is typically extended for an additional two days after the eye appears to have recovered. However, for cats, the duration of treatment should be discussed with your veterinarian as there is increased risk of blood disorders in long term use. Note, the precise dosage and frequency of application will depend on the specific infection and your pet's health status. Following your veterinarian's instructions is vital.  

Missed dose:

If a dose is missed, consult your veterinarian for the appropriate course of action. For eye ointments, it is generally advised to give the missed dose as soon as you remember, then give the next dose as scheduled. However, do not double dose.

Contraindications and Precautions

This medication is not recommended for dogs that are used for breeding, nor should it be given to pregnant or nursing females.
