Apply a thin layer of naftifine gel (Naftin) to the affected areas on your skin. For treating athlete's foot with the 2% strength of the gel, make sure to also apply the medication to the skin in between the toes.
Wash your hands with soap and water before you use naftifine gel (Naftin) to help avoid introducing more germs to the infection.
Also wash your hands with soap and water after you use the gel, unless you're treating your hands. This helps prevent accidentally getting medication in your eyes or other sensitive areas of the body. If the medication gets in your eyes, rinse them well with water.
Naftifine gel (Naftin) isn't meant to be used in the eyes, mouth, or vagina. Be careful if you're applying the medication to the skin around or near those areas, as it can cause burning and irritation there. If you do accidentally get naftifine gel (Naftin) in those spots, wash it well with water.
Use naftifine gel (Naftin) for the full recommended time (4 weeks for the 1% strength or 2 weeks for the 2% strength). Don't stop using it early, even if your symptoms improve. Stopping treatment too soon can make your infection more likely to return.
Itching, burning, and skin irritation are possible side effects. Contact your prescriber if these side effects worsen over time or if you notice blistering, swelling, or oozing. These might be signs of a different, more serious skin condition.
Don't cover the areas where you apply naftifine gel (Naftin) with bandages or dressings unless your prescriber tells you to. Usually, you want your skin to be able to "breathe" and stay dry if it has a fungal infection.
If you're pregnant or breastfeeding, talk to a healthcare professional about how to best treat fungal skin infections. There isn't enough information to know whether naftifine gel (Naftin) is safe during pregnancy or while breastfeeding.
Store your tube of naftifine gel (Naftin) at room temperature in a cool and dry spot away from pets and children. Contact your local Poison Center right away at 1-800-222-1222 if a child or animal swallows any of the medication.
Naftifine gel (Naftin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Only apply naftifine gel (Naftin) to the surface of your skin. Never place the medication into the eyes, nose, or vagina. Applying naftifine gel (Naftin) to these sensitive areas can cause pain and irritation. Let your prescriber know if your skin becomes irritated or sensitive while you're using this medication. You might have to switch to a different medication.
Age 18 years and older: Apply a thin layer to the affected area(s) twice per day (morning and evening) for 4 weeks.
Age 12 years and older: Apply a thin layer to the affected area(s) once per day for 2 weeks. Be sure to also apply the medication to about a half-inch of healthy skin surrounding the affected area(s).
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
