How Terbinafine Treats Fungal Skin Infections
What is Terbinafine?
Terbinafine is a topical antifungal medication that is used to treat fungal skin infections, such as athlete's foot and ringworm. It is available in cream, gel, and spray forms.
How Does Terbinafine Work?
Terbinafine works by inhibiting the growth of fungi. It does this by interfering with the production of ergosterol, which is a component of the fungal cell membrane. Without ergosterol, the fungal cell membrane cannot function properly and the fungus cannot grow.
How to Take or Use Terbinafine
Terbinafine should be applied to the affected area once or twice daily, as directed by your doctor or pharmacist. The length of treatment will vary depending on the type of infection you have.
When applying terbinafine, be sure to clean the affected area first. Apply the medication in a thin layer and rub it in gently. Avoid getting the medication in your eyes, nose, or mouth.
