Summary
Terbinafine is used to treat fungal infections, which are conditions caused by fungi, such as athlete's foot, ringworm, and nail fungus. These infections can cause symptoms like itching, redness, and scaling. Terbinafine helps clear these infections by stopping the growth of fungi.
Terbinafine works by inhibiting an enzyme in fungi, which stops them from producing a substance they need to grow. This action helps clear the infection, similar to cutting off the food supply to a plant, causing it to wither.
The usual dose of Terbinafine for adults is 250 mg once daily. It can be taken orally, which means by mouth, or applied topically, which means directly on the skin, depending on the type of infection. Always follow your doctor's dosing instructions.
Common side effects of Terbinafine include headache, diarrhea, and upset stomach, which refers to discomfort in the stomach area. These effects vary from person to person and are usually mild. If you notice new symptoms, talk with your doctor.
Terbinafine can cause liver problems, so your doctor may monitor your liver function during treatment. It's not recommended for people with severe liver or kidney issues. Avoid alcohol, which can increase liver damage risk. Always inform your doctor about all medications you're taking to avoid interactions.
