What the medication is used for
AURO-TERBINAFINE is used to treat fungal infections of skin, fingernails and toenails:
AURO-TERBINAFINE is used to treat fungal infections of the nail (toes, fingers) and may be used for certain fungal skin infections that do not respond to topical treatment.
Consult your doctor to confirm which type of fungal skin infection you have. Your doctor can determine if AURO-TERBINAFINE is the right treatment for you.
The treatment should only be taken as prescribed by your doctor. Some evidence of infection may still be present at the end of treatment. This will gradually diminish.
What it does
Terbinafine interferes in the production of a substance (ergosterol) that the fungus needs to grow and causes a build-up of another substance in the cells (squalene). Both actions cause the death of the fungus and elimination of the infection.
When it should not be used
Do not use AURO-TERBINAFINE if you are allergic to terbinafine (the active antifungal ingredient) or any of the ingredients in the formulation (See What the nonmedicinal ingredients are). If you think you may be allergic, ask your doctor for advice.
Do not use AURO-TERBINAFINE if you have chronic or active liver disease.

Proper use of this medication
To help clear up your infection completely, it is very important that you keep taking this medicine for the prescribed treatment period, even if your symptoms begin to clear up or you begin to feel better after a few days. Since fungal infections may be very slow to clear up, stopping your medication too soon can cause the symptoms and the fungal infection to flare up again.
Missed Dose
Try not to miss any doses. If you do miss a dose, take it as soon as possible. However, if it is almost time for your next dose (up to 4 hours), skip the missed dose and go back to your regular schedule. Do not double the doses and never make dose changes on your own. Take as prescribed by your doctor.
Usual Adult Dose
Follow your doctor’s instructions carefully. Do not exceed the recommended dosage. If you have the impression that the effect of AURO-TERBINAFINE is too strong or too weak, talk to your doctor or pharmacist.
