This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Precautions
Before taking Terbinafine tell your doctor or pharmacist
- if you are allergic to terbinafine or any other medications
- what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking.
- if you have or have ever had kidney or liver disease, human immunodeficiency virus (HIV), or acquired immunodeficiency syndrome (AIDS).

Directions
Terbinafine comes as a tablet to take by mouth. It is usually taken once a day for 6 weeks for fingernail fungus and once a day for 12 weeks for toenail fungus. Follow the directions given to you by your doctor or pharmacist, and ask your doctor or pharmacist to explain any in directions you do not understand. Take terbinafine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your fungus may not be completely cured until a few months after you finish taking terbinafine. This is because it takes time for a healthy nail to grow in.
Missed Dose
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
