Nail Fungus Formulas

The Nail Fungus Formula is a customized prescription blend that may include ingredients such as; fungicide and fungistatic antifungals, and penetration enhancers that target the main symptoms of localized fungal infections. It is an odorless nail polish typically applied to the affected area(s) two to three times daily.

What is the Nail Fungus Formula?

The Nail Fungus Formula combines prescription ingredients in a proprietary base developed specifically to deliver ingredients through the nails. It is a topical solution that can be applied on, around, and under the nails. The Nail Fungus Formula is specifically made without fragrance or gluten.

Topical vs. Oral

Topical applications are known to have a lower-side effect profile when compared with systemic administration. Because the drugs are being applied directly to the nails, there is no first-pass metabolism by the liver. As a result, lower doses of the drugs may be used to get the intended response compared to the oral route. Research has shown topical application may reduce the risk of serious gastrointestinal, renal, and cardiovascular adverse events compared with oral treatment options. However, you should always discuss the benefit to risk ratio with your healthcare prescriber.

Common Ingredients


Clotrimazole is in a class of medications called Imidazole antifungals. It kills fungus by causing holes to appear in its cell membrane and the contents leak out. This kills the fungus and treats the infection.


Fluconazole is in a class of medications called Triazole antifungals. It kills fungus by causing holes to appear in its cell membrane and the contents leak out. This kills the fungus and treats the infection.


Terbinafine is in a class of medications called Allylamine antifungals. It kills fungus by causing holes to appear in its cell membrane and the contents leak out. This kills the fungus and treats the infection.


Urea is a humectant, which means it is able to absorb moisture from the environment and draw it to the nail. In addition, urea is also an exfoliant that softens the nail.

Frequently asked questions

What is a compounded medication?

One size doesn’t fit all and every patient is unique. Drug compounding is the process of combining, mixing, or altering ingredients to create a medication tailored to the needs of a patient by a pharmacist as the result of a practitioner’s prescription drug order. While compounded medications are not FDA-approved, they serve an important patient need—especially when FDA-approved medication is not available for treatment. Our formulations are made to order in small batches to ensure freshness. The specific ingredients in your compounded formula will depend on your specific concerns and goals. It should be understood that your personal healthcare practitioner will make the final decision.

Are compounded medications FSA & HSA eligible?

Yes! All of our compounded formulations, regardless of ingredients, are eligible for Flexible Spending Accounts (FSA) and Health Saving Accounts (HSA).

What is nail fungus?

Nail fungus affects millions of people, but many go months or even years without getting treatment. Toenail fungus commonly affects seniors with chronic medical conditions or more serious underlying conditions. Diabetes, circulatory problems, or immune-deficiency conditions can contribute to toenail fungus which is caused by an infection under the surface of the nail. It can lead to discomfort, pain, and may impair your ability to walk if left untreated. Many people don’t recognize the symptoms of toenail fungus, including white marks on the nail bed, distorted shape, discoloration, or a thickening of the nail. It may affect one or several nails, and can affect ambulatory and non-ambulatory patients.

When should I see improvement in my symptoms?

Based on research and patient testimonials, you may see improvements in 48 to 52 weeks; however, each patient is unique and time frames may differ.
