Ketoconazole is an antifungal medication used to treat fungal and yeast infections in dogs and cats. It is commonly prescribed for skin infections, ear infections, ringworm, and certain systemic fungal diseases. It works by stopping the growth of fungus and yeast, helping relieve symptoms such as itching, redness, hair loss, odor, and discomfort.

Ketoconazole may also be used in specific cases to help manage conditions related to excess cortisol production, such as Cushing’s disease, under close veterinary supervision.

Because this medication can affect the liver and may interact with other medications, it should always be used exactly as directed by your veterinarian. Monitoring and follow-up testing may be recommended during treatment.
