Why Prescribed
To treat tinea pedis (athlete's foot), a fungal infection.

How It Works
Butenafine prevents fungal organisms from producing vital substances required for their growth and function. This drug is effective only for infections caused by fungal organisms. It will not work for bacterial or viral infections.

Range and Frequency
Apply it to the affected area either twice a day for 7 days or once a day for 4 weeks, in accordance with your doctor' s instructions.

Onset of Effect
Unknown.

Duration of Action
Unknown.

Dietary Advice
No special restrictions.

Storage
Store in a tightly sealed container away from heat, moisture, and direct light. Do not allow the cream to freeze.

Missed Dose
Apply butenafine as soon as you remember. If it is near the time for the next dose, skip the missed dose and resume your regular dosage schedule. Do not double the next dose or apply an excessively thick film of topical medication to compensate for a missed dose.

Stopping the Drug
Apply as prescribed for the full treatment period, even if the fungal infection appears to be eradicated before the scheduled end of therapy. Unfortunately, it can be difficult to assess when the drug has achieved its desired effect since it suppresses redness and inflammation of the skin before the infection is completely clear; recurrence of fungal infection owing to inadequate length of therapy is a significant risk.

Prolonged Use
If your skin problem does not improve or instead becomes worse after 4 weeks of treatment, consult your doctor.

Over 60
No special problems are expected.

Driving and Hazardous Work
The use of butenafine should not impair your ability to perform such tasks safely.

Alcohol
No special precautions are necessary.

Pregnancy
Adequate human studies have not been done. Before taking butenafine, tell your physician if you are pregnant or plan to become pregnant.

Breast Feeding
It is not known whether butenafine passes into breast milk; caution is advised. Consult your doctor for specific advice.

Infants and Children
The safety and effectiveness of butenafine use by children below the age of 12 have not been determined. Use of the medication in patients 12 to 16 years of age has not caused any problems and has been effective.

Special Concerns
Butenafine is intended for external use only. Wash your hands after butenafine is applied to the affected area. Contact with the eyes, nose, and mouth should be avoided. If you apply butenafine after bathing or showering, dry the affected area thoroughly first. Do not use a tight-fitting dressing unless your physician tells you to do so. Do not use butenafine for any condition other than the one for which it was prescribed. As with any antifungal, butenafine is useful only against organisms that are vulnerable to its effects. Therefore, it is important to tell your doctor if your condition has not improved--or instead has worsened--within a few days of starting butenafine. The particular organism causing your illness may be resistant to this drug.

Overdose Symptoms
No cases of overdose have been reported.

What to Do
An overdose of butenafine is unlikely to be life-threatening. However, if someone uses a much larger dose than prescribed or ingests the medicine, seek medical assistance immediately.

Drug Interactions
Consult your doctor for specific advice if you are taking allylamine antifungal drugs. Also tell your doctor if you are taking any other prescription or over-the-counter medications.

Food Interactions
No known food interactions.

Disease Interactions
Caution is advised when taking butenafine. Consult your doctor if you have any other medical condition.
