Key takeaways
Terbinafine (brand name: Lamisil) and Tinactin (generic name: tolnaftate) are both antifungal medications, but they have some key differences. Terbinafine oral tablet is a prescription-only medication primarily used to treat fungal infections of the toenails and fingernails, while Tinactin is an over-the-counter topical treatment for skin fungal infections like athlete's foot, ringworm, and jock itch. Terbinafine works by preventing the fungus from forming its protective outer layer, whereas Tinactin blocks a protein that fungi need to grow. Terbinafine is taken once daily and can take several weeks to show results, with potential side effects including headache, rash, and liver damage. On the other hand, Tinactin is applied to the skin twice daily and typically causes only mild skin irritation. Tinactin is available in various forms such as sprays, creams, and powders. Oral terbinafine requires a prescription but is also available over-the-counter in topical forms.
