Which of the following treatments is NOT used for candidiasis?

Trimethoprim-sulfamethoxazole is primarily an antibiotic that is used to treat a variety of bacterial infections and is not effective against fungal infections, including candidiasis. Candidiasis is caused by yeast fungi from the Candida species, and treatment typically involves antifungal medications.

Fluconazole and clotrimazole are antifungal agents specifically indicated for the treatment of candidiasis. Fluconazole is commonly used due to its efficacy in treating systemic and mucosal infections caused by Candida, while clotrimazole is often utilized for superficial and topical infections. Amphotericin B, although primarily reserved for more serious, systemic fungal infections, can also be used in cases of severe candidiasis.

Thus, the appropriate medications for candidiasis involve those that have antifungal properties, whereas Trimethoprim-sulfamethoxazole lacks such efficacy against fungal pathogens.
