Sec.  524.390b  Chloramphenicol ophthalmic solution.

    (a) Specifications. Each milliliter contains 5 milligrams of 
chloramphenicol.
    (b) Sponsor. See No. 017030 in Sec.  510.600(c) of this chapter.
    (c) Conditions of use. Dogs and Cats. (1) Amount. Apply one or two 
drops, 4 to 6 times a day for the first 72 hours, depending upon the 
severity of the condition. Intervals between applications may be 
increased after the first 2 days.
    (2) Indications for use. Treatment of bacterial conjunctivitis 
caused by organisms susceptible to chloramphenicol. Therapy should be 
continued for 48 hours after the eye appears normal.
    (3) Limitations. Therapy for cats should not exceed 7 days. As with 
other antibiotics, prolonged use may result in overgrowth of 
nonsusceptible organisms. If superinfection occurs, or if clinical 
improvement is not noted within a reasonable period, discontinue use, 
and institute appropriate therapy. Prolonged use in cats may produce 
blood dyscrasias. Chloramphenicol products must not be used in meat-, 
egg-, or milk-producing animals. The length of time that residues 
persist in milk or tissues has not been determined. Federal law 
restricts this drug to use by or on the order of a licensed 
veterinarian.
