Ringworm, which is caused by several types of fungi, presents as a circular rash with hair loss in the early stages. A highly contagious disease, ringworm needs immediate attention by a veterinarian. After confirming the diagnosis your vet may prescribe ketonconazole to treat the infection.

Ketoconazole Classification

Ketoconazole is classified as a imidazole. Imidazoles are drugs that treat multiple types of infections such as fungal, bacterial and protozoan.
Administration
-
Ketoconazole can be given orally or topically. For dogs that have ringworm over much of the body, a ketoconazole shampoo is available. Often both a topical and oral treatment is required.
Using Ketoconazole
-
Follow your veterinarian's instructions for using ketoconazole. Creams often need to be applied twice a day. Oral medications may need to be given for several months.
Side Effects
-
Side effects are most often associated with oral ketoconazole. The most common side effects are nausea, diarrhea, vomiting and liver problems. More serious side effects include birth defects and reproductive disorders.
Cautions
-
Ketoconazole taken orally can interact with other medications. Before giving your dog ketoconazole, inform your vet of any other medications your dog is being given. Because of the risk of birth defects and reproductive disorders, do not give ketoconazole to breeding or pregnant dogs.
