Which medication is commonly prescribed to treat oral thrush?

Nystatin is commonly prescribed to treat oral thrush because it is an antifungal medication specifically effective against Candida species, which are the primary cause of oral thrush. Oral thrush, or oropharyngeal candidiasis, is characterized by white patches in the mouth and can occur in individuals with weakened immune systems or those taking antibiotics.

Nystatin works by binding to the fungal cell membranes, increasing permeability, and causing cellular contents to leak out, ultimately leading to the death of the fungus. It is frequently used as a topical treatment, often administered as a lozenge or oral suspension that must be swished in the mouth to effectively target the infection.

Other medications, while they may have antifungal properties, are not typically the first line of treatment for oral thrush. Fluconazole, for instance, is an effective oral antifungal that can also treat oropharyngeal candidiasis, but it is usually prescribed in cases where Nystatin is not effective or for more severe cases. Amoxicillin and ciprofloxacin are antibiotics and do not target fungal infections, making them ineffective for treating oral thrush.
