Benzylamine antifungals are used to treat athlete's foot, jock itch, and ringworm. These medications work by stopping the growth of fungi, which helps to clear up the infection. Benzylamine antifungals are typically available in topical forms like creams and gels. An example includes butenafine (Lotrimin Ultra). You can apply these directly to the affected area to help relieve symptoms and eliminate the infection.
