I buy my clortrimazole in dual packs at Costco because it's a very good all-around anti-fungal to have on hand (treats yeast infections like a charm, AND it's WAY cheaper than Monistat or other OTC treatments). Highly recommended--my mom used it to clear up a fungal infection on her knee from an old indoor soccer injury and my dad uses it for athlete's foot. Very multipurpose and easy to find
Hope it helps you, SiN
