Topical antifungal agent for dogs and cats.

Miconazole medication is used to treat skin infections such as athlete's foot, jock itch, ringworm, and other fungal skin infections (candidiasis). This medication is an azole antifungal. It works by stopping the growth of yeast (fungus) that causes the infection.

Indications/Actions:

Topical miconazole has activity against dermatophytes and yeast. It is especially effective for the treatment of Malassezia dermatitis. Patients with severe, generalized infections may require systemic therapy. Lotions, sprays, and creams are generally used for localized lesions associated with Malassezia spp or dermatophytes. Topical miconazole products are generally ineffective (or minimally effective) when used alone for dermatophytosis; adjunctive systemic treatment is usually required.

Miconazole’s actions are a result of altering permeability of fungal cellular membranes and interfering with peroxisomal and mitochondrial enzymes, leading to intracellular necrosis. Miconazole products are fungicidal with repeated application. 

Suggested Dosages/Use:

Apply a light covering to affected areas, once daily for 2 to 4 weeks. See accompanying literature for full directions.

Avoid contact with eyes, since irritation may result.

Wash hands thoroughly after administration to avoid spread of fungal infection.
