Itraconazole Capsules 200 mg for dog

Itraconazole Capsules 200 mg is a prescription oral antifungal formulated for dogs requiring systemic treatment of moderate to severe fungal infections. It is commonly selected when topical therapy is insufficient or when infections involve internal organs, deep tissues, or widespread skin involvement.

When Veterinarians Prescribe Itraconazole

Itraconazole may be prescribed for dogs diagnosed with:

• Blastomycosis
• Histoplasmosis
• Aspergillosis (localized forms)
• Cryptococcosis (non-CNS cases)

• Systemic yeast or fungal infections
• Refractory fungal infections unresponsive to topical therapy

How Itraconazole Works

Itraconazole inhibits ergosterol synthesis, an essential component of fungal cell membranes.  Without ergosterol, fungal cells lose structural integrity and cannot survive.
