How do I use the Fungi-Nail pen applicator?

First, hold the pen with the brush pointing downwards. Remove cap and on opposite tip of brush (top of the pen) twist 3 times to the right (clockwise). You will not see the solution dripping nor will you be able to tell if the brush is moist since the solution is clear. Place brush against the skin to see that the brush is moist with solution. Use until brush becomes dry, then follow the same steps. There is a “How-to-Apply” video on our website at www.funginail.com.

Why does the Fungi-Nail labeling say not effective on nails and scalp if it is called Fungi-Nail?

The statement you are referring to (not effective on scalp or nails) is one that’s required by the FDA on all over-the-counter antifungal products since there is no OTC product that will penetrate the nail. Since fungus grows on the nail bed and surrounding skin, not the actual nail, you are to apply Fungi-Nail under the nail and around the cuticle area of the affected toe or finger.

How long does it take to heal fungus underneath the toenail?

If you apply Fungi-Nail Pen as directed, depending on the severity of your fungal infection, you should start to see results within 4-8 weeks; remember that it can take up to 9-12 months for a healthy nail to fully grow out.

How can I buy this product outside the U.S.?

Currently, Fungi-Nail is available in the USA, Canada and Puerto Rico.

Can nail polish be worn while using Fungi Nail?

Nail polish can be applied AFTER treating with Fungi-Nail. Since treatment area is very close to the nail, it is best to apply to the affected areas where the nails have no nail polish, therefore, nail polish should be removed prior to each application of Fungi-Nail. After application and area is fully dried, nail polish can be applied.

How do I get a refund?

To receive a refund, please mail in a copy of the store receipt, the UPC bar code and a brief note stating your reasons for requesting a refund. Once received, it will take about 4-6 weeks to receive a refund check in the mail.

Where can I buy Fungi-Nail? How much does it cost?

Fungi-Nail products are available nationwide at most drug stores and online at Wal-Mart, CVS, Walgreens, Target, Rite Aid, Duane Reade and many grocery chains. The price varies depending on the particular product, retailer and location but usually ranges between $9-$16

What is the limit of the number of applications I can use per day?

We recommend applying twice daily for optimum results.

Do you need to click the pen brush applicator 3 clicks each time you apply?

Twist the pen brush applicator 3 times for initial use and then as needed for subsequent application. Make sure you do not twist more than 3 times for each application in order to avoid leakage.

What is the active ingredient and concentration in Fungi-Nail products?

We are transitioning the entire Fungi-Nail line to contain 1% tolnaftate, the maximum concentration allowed by FDA for an over-the-counter product. However, some Fungi-Nail products at retail might list the active ingredient as 25% undecylenic acid.

Can I shower/swim after applying Fungi-Nail?

It is recommended that you allow the solution to dry before continuing with your daily routine, especially if it involves water. To avoid the product washing off, it is recommended that you wait for Fungi-Nail to dry before exposing the treated areas to water.

Do you have free samples of Fungi-Nail available?

We currently do not have samples of Fungi-Nail at this time. However, we do have coupons available on our website at www.funginail.com. If you do not have a computer or do not have access to the internet, we would be happy to send some coupons by mail.

How do I apply Fungi-Nail?

In order for our product to work effectively, you must apply on the skin all around the nail and underneath the nail as best as you can. Our product will not penetrate the nail.

If I use Fungi-Nail, does the current nail fall off?

Each case of nail fungus is unique. The nail may fall off or it may not. It is recommended that you continue applying Fungi-Nail as directed until the nail has fully grown out.

Can I find Fungi-Nail when I travel internationally?

Kramer currently distribute Fungi-Nail products within the US, Canada and Puerto Rico.

Can my nail fungus spread to other parts of the body?

Nail and foot fungus is easily spread from one area of the body to other areas of the body if not treated properly. It can grow rapidly in wet or moist environments including showers and closed shoes.

I have been using Fungi-Nail for several weeks and my toe fungus is not getting better, what should I do?

If you do not see improvement in 4 weeks or your condition begins to worsen or persist, or irritation occurs, please consult your health care professional (doctor or pharmacist).

I have been using Fungi-Nail Pen but it doesn’t last the 8 weeks as stated on the package.

Fungi-Nail Pen contains enough medication to last approximately 8 weeks when applied to one affected nail area (cuticle and skin under the nail). If you are treating more than one area, Fungi-Nail Pen will likely run out before 8 weeks of treatment.

What is the difference between Fungi-Nail Pen antifungal treatment and cosmetic nail renewal treatments such as Kerasal Nail? Can I use both products at the same time?

Fungi-Nail contains an antifungal drug ingredient to treat toe and foot fungus and is classified by FDA as an OTC drug product for treatment of fungal infections. Nail renewal treatments like Kerasal Nail are cosmetic products marketed to temporarily improve the appearance of the nail and do not treat the actual fungus infection. However, it is safe to use both Fungi-Nail and nail renewal treatments at the same time.

Which Fungi-Nail Toe & Foot product is right for me?

Fungi-Nail Solution is a liquid formula in a 1-ounce bottle that’s economical for treating more than one affected nail area. Fungi-Nail Pen has a pinpoint brush applicator to provide targeted treatment that gets the right amount right where it’s needed. Fungi-Nail Ointment provides a more occlusive option for stubborn fungal infections.

Are there any tips to help prevent fungal infections?

In order to help prevent fungal infections, follow these steps:

  • Keep your nails short, dry and clean.
  • Trim nails straight across and file down thickened areas.
  • Wear socks and change them at least every 24 hours.
  • Wear comfortable shoes that are not too tight so your feet can “breathe”.
  • Use an anti-fungal product as soon as you notice an infection to help keep it from spreading.
  • Select a well-known manicure and pedicure salon and bring your own instruments.
  • Do not trim or pick at the skin around your nails.
  • Do not walk barefoot in public places such as pools, locker rooms and /or showers.
  • Since fungal infections can spread from one person to another and from one area of your body to another, wash your hands after applying any topical antifungal product.

How long will it take me to see results?

Using Fungi-Nail as directed, you may begin to see results with 4-8 weeks. However, you may need to keep using Fungi-Nail for longer period to allow for the re-growth of healthy, new tissue.

What if I don’t know what type of fungal infection I have?

If you are not sure what type of fungal infection you have, it is best to see a doctor so that he/she can help you.

Can I wear nail polish or acrylic nails while using Fungi-Nail?

All Fungi-Nail Toe & Foot products are nail polish and acrylic friendly. However, letting infected nails “breath” can help speed recovery. Fungi-Nail is applied to the skin around your cuticle and underneath the tip of the nail and not directly to the nail itself, so it will not damage your manicure or pedicure. If you do choose to polish your nails, Fungi-Nail should be applied before applying nail polish or acrylics.

Is Fungi-Nail recommended by health care professionals?

Fungi-Nail is the #1 pharmacist recommended brand and have been successfully treating fungus for more than 25 years.
