Key takeaways
Itraconazole (Sporanox, Tolsura) and miconazole (Oravig) are both antifungal medications used to treat fungal infections, but they differ in their specific uses and forms. Itraconazole is available in oral capsules and is used for severe fungal infections like blastomycosis, histoplasmosis, and aspergillosis, as well as fungal nail infections. Miconazole, on the other hand, is available as a buccal tablet and is specifically used for oral thrush in the mouth and throat. While itraconazole is taken with food and can be used for several months, miconazole is placed in the mouth once daily for 14 days. Itraconazole is available as a generic, making it more affordable, whereas miconazole does not have a generic version. Common side effects of itraconazole include nausea and rash, while miconazole may cause mouth discomfort and diarrhea. Itraconazole has significant drug interactions and can cause serious heart-related side effects, whereas miconazole's main concern is potential allergic reactions.
