Itraconazole oral solution, also known by its brand name Sporanox, is an azole antifungal used to treat adults with fungal infections in the mouth and throat (oral thrush) and esophagus. You typically swish and swallow the dose once or twice a day on an empty stomach. Itraconazole (Sporanox) oral solution isn't a first-choice treatment option because it can interact with many other medications. It also has rare but serious side effects like heart failure, liver problems, and hearing loss.
