Since Sam experienced a hypersensitivity reaction to clotrimazole, it would be best to avoid using azole antifungals like miconazole and ketoconazole. Griseofulvin is not typically used for athlete's foot. Terbinafine is a good option as it is a different class of antifungal that works by inhibiting fungal cell wall synthesis and has a lower risk of cross-reactivity with clotrimazole.
