Medications for candidiasis are used to treat yeast infections, thrush, and fungal skin infections. These medications also have other uses, such as treating fungal infections in the lungs or in other parts in the body. They work by stopping the growth of fungi, helping to clear up the infection. Common classes include azoles, polyenes, and antimetabolites. Azoles like ketoconazole (Nizoral) and voriconazole (Vfend) are available in oral forms. Polyenes, such as nystatin (Nystop), come in oral and topical forms. Antimetabolites like flucytosine (Ancobon) are usually taken as oral pills. These options provide different ways to help manage and treat fungal infections effectively.
