Chlorsig (Chloramphenicol)

Chlorsig is an antibiotic eye drop for treating bacterial eye infections. Chlorsig contains Chloramphenicol as the primary active ingredient. This prescribed medication is a topical antibiotic drop that treats a range of bacterial infections affecting the eye. It is typically reserved for specific types of infections such as bacterial conjunctivitis. It is a human prescription medication that may be prescribed by a veterinarian off-label for use in pets.

As a broad-spectrum antibiotic, Chlorsig is effective against various susceptible gram-positive and gram-negative bacteria. It functions by hindering the production of crucial proteins within these susceptible bacteria, thereby efficiently managing the infection.

Prior to applying Chlorsig, clean the area surrounding the eye to remove any discharge or crusts. Give as directed by your veterinarian.

• Tilt your pet's head back slightly. Using your free hand, gently pull down the lower eyelid to create a small pocket.
• Squeeze the prescribed number of drops into the pocket, not directly on the eyeball, to avoid injuring the eye.
• Release the eyelid and let your pet blink, spreading the medication over the eye's surface.

The treatment is typically extended for an additional two days after the eye appears to have recovered. Note, the precise dosage and frequency will be determined by your veterinarian as it will depend on the severity and type of infection. Wash hands after use.

Missed Dose:

If a dose is missed, consult your veterinarian. It is typically advised to give the missed dose as soon as you remember and to give the next dose at the scheduled time. Avoid double dosing.
