The Veterinary Use of Ketoconazole (Nizoral) in PetsVeterinary & Aquatic Services Department, Drs. Foster & SmithKetoconazole is an antifungal medication used for the treatment of serious, deep fungal infections, such as blastomycosis, histoplasmosis, aspergillosis, and cryptococcosis. It may also be used against some yeast and dermatophyte (ringworm) infections. It has also been used to treat Cushing's disease (hyperadrenocorticism). Contact your veterinarian if your pet experiences lack of appetite, vomiting, diarrhea, liver toxicity (jaundice - yellowing of gums, skin, or eyes) or bleeding problems while being treated with ketoconazole. Itraconazole, a similar medication, generally produces fewer side effects although it is more expensive.
