Terbinafine

Terbinafine is an antifungal medicine used to treat certain fungal infections of the skin, nails, and scalp. It works by blocking an enzyme that fungi need to build their cell membranes, which helps stop the infection from growing.

It is commonly used for athlete’s foot, ringworm, jock itch, and nail fungus. Some forms are taken by mouth and others are applied to the skin. Use only as directed, and tell your prescriber about liver disease, pregnancy, breastfeeding, and any other medicines you take.
