524.520—Cuprimyxin cream.
(a) Specifications.
The drug contains 0.5 percent cuprimyxin (6-methoxy-1-phenazinol 5, 10-dioxide, cupric complex) in an aqueous cream base.
(c) Conditions of use.
(1)
Cuprimyxin is a broad spectrum antibacterial and antifungal cream for the topical treatment of superficial infections in 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.
