General description

Miconazole is an antifungal drug used in the treatment of skin fungal infections called dermatophytosis (ringworm) in dogs, cats and other pets. Side effects are rare.

Uses

Dermatophyte (ringworm) infections

How it works

Miconazole stops the cell membrane of the fungus from being able to form which then causes fungal cell death.

What results can I expect?

Skin lesions from the ringworm infection should start to become smaller and less irritated with continued use; this can take several weeks.

Missed Dosage

If a dose is missed, the medication can be applied right away to make up for the missed dose.
