horses, dogs, and cats caused by bacteria, dermatophytes (Trichophyton 
spp., Microsporum spp.) and yeast (Candida albicans) affecting skin, 
hair, and external mucosae.
    (2) The cream is applied twice daily to affected areas by rubbing 
into lesions. Treatment should be continued for a few days after 
clinical recovery to avoid possible relapses.
    (3) After application to cutaneous areas, a change in color from 
dark green to pink is due to the liberation of free myxin from its 
copper complex.
    (4) If no response is seen within seven days, diagnosis and therapy 
should be reevaluated. If any adverse local reaction is observed after 
topical application, discontinue treatment.
    (5) Federal law restricts this drug to use by or on the order of a 
licensed veterinarian.
