Key takeaways
Terbinafine (Lamisil) and Sporanox (itraconazole) are both antifungal medications, but they are used to treat different types of fungal infections. Terbinafine is primarily used to treat fungal infections of the fingernails and toenails, while Sporanox is used to treat oral fungal infections like thrush. Terbinafine is taken once a day and can be taken with or without food, whereas Sporanox must be taken on an empty stomach for better absorption. Terbinafine can cause side effects like headache, rash, and upset stomach, and it can also lead to changes in taste or smell. On the other hand, Sporanox can cause nausea, diarrhea, and serious heart problems, including congestive heart failure. Both are available with a prescription, but terbinafine also has over-the-counter topical forms available. Additionally, Sporanox interacts with many other medications, which can be dangerous, while terbinafine has fewer interactions but can still affect other medications you might be taking.
