Which medication is commonly prescribed for treating candidiasis?

Fluconazole is the medication commonly prescribed for treating candidiasis, which is an infection caused by yeast, particularly Candida species. As an antifungal agent, fluconazole works by inhibiting the growth of the fungus, making it effective in treating various forms of candidiasis, including oropharyngeal and vaginal infections.

This medication is preferred due to its efficacy and the convenience of oral dosing, as it can effectively reach the affected areas in the body. It's also notable that fluconazole is often well-tolerated, with a favorable safety profile, which contributes to its widespread use.

Acyclovir is an antiviral medication used primarily for infections caused by certain viruses, such as herpes simplex, and is not effective against fungal infections like candidiasis. Amoxicillin and ciprofloxacin are antibiotics used to treat bacterial infections, and they do not have activity against fungi, thus making them inappropriate options for candidiasis treatment.
