Key takeaways
Terbinafine (Lamisil) and Oravig (miconazole) are both antifungal medications, but they treat different types of fungal infections and are used in different ways. Terbinafine tablet is taken orally and is primarily used to treat fungal infections of the fingernails and toenails. It is a first-choice treatment and is taken once daily for 6 to 12 weeks. Common side effects include headache, rash, diarrhea, and upset stomach. On the other hand, Oravig is used to treat oral thrush and comes as a buccal tablet that dissolves in your mouth over 6 hours. It is taken once daily for 14 days. Common side effects of Oravig include mouth discomfort, diarrhea, headache, and nausea. While terbinafine has a lower-cost generic available, Oravig does not. Additionally, terbinafine can cause serious side effects like liver damage and changes in taste or smell, whereas Oravig can cause allergic reactions and is contraindicated if you have a milk protein allergy.
