For over 50 years, the FDA has approved the use of tolnaftate for the treatment and prevention of athlete’s foot and ringworm. Tolnaftate is used in well over 70 products worldwide. These tolnaftate products, found at the pharmacy and sold online are suspensions of tolnaftate. Formula 3® is different, it is not a suspension.

The tolnaftate in Formula 3® is in-solution. Formula 3® was the first product available to patients utilizing Tetra’s patented technology which uses natural jojoba oil as the vehicle. Simply put, Tetra’s process makes it impossible to separate the tolnaftate from the jojoba oil. So, when the jojoba oil is quickly absorbed by the skin, the tolnaftate is delivered directly to the infected area right along with it!


In fact, Formula 3® Antifungal is so effective, that it’s received the American Podiatric Medical Association’s Seal of Approval.
For best results, we recommend you apply fast-acting, quick-absorbing Formula 3® Antifungal after showering, when the skin has the greatest capacity for absorption. (See instructions below). Typically, your bottle of Formula 3® Antifungal will last between three and six months, making it an exceptional value.

Although Formula 3® Antifungal was developed to assist in healing, it may not be for everyone. Because tolnaftate has a pregnancy rating of Category C, you should consult your physician before using if you are pregnant or nursing. What’s more, the natural oils in Formula 3® Antifungal condition the skin and do not contain essential oils, so the risk of an allergic reaction is very rare. However, some people with hypersensitive skin may experience redness and/or itching. If this occurs, stop treatment and contact your physician.


Formula 7® is the only paraben free soluble tolnaftate antifungal microemulsion fortified with cosmetic ingredients and bactericidal agents.

What makes Formula 7® unique?

  1. Soluble Tolnaftate – A technology developed by The Tetra Corporation and used first in Formula 3®.

  2. Formula 7® is the first tolnaftate microemulsion.

  3. Formula 7® is formulated with cosmetic ingredients that rehydrate and restore the natural physical properties and appearance of the skin and nail with each use.  The cosmetic ingredients are C12-15 Alkyl Benzoate, Jojoba Seed Oil, Glycerin, PEG-20 Hydrogenated Lanolin, Urea, Vitamin E Acetate, and Caprylyl Glycol.

  4. The N-acetyl-l-cysteine (NAC) in Formula 7® is a penetration enhancer specifically designed to increase tolnaftate flux through keratin.  Studies have also found that NAC has bactericidal properties and breaks down bacterial biofilms of clinically relevant pathogens including Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, Enterobacter cloacae, Staphylococcus epidermidis, and Klebsiella pneumoniae.

  5. Formula 7® contains urea to increase the water content of the top layers of the skin. Urea gently dissolves the intercellular matrix, which results in loosening the horny layer of skin and shedding scaly skin at regular intervals, thereby softening hyperkeratotic areas. Urea also hydrates and gently dissolves the intercellular matrix of the nail plate, which can result in the softening and increasing permeability of the nail plate for cosmetic debridement.

  6. Melaleuca Alternifolia (Tea Tree) Oil adds benefits of an antifungal, antiseptic, germicidal and anti-bacterial properties.

  7. A new ½ fl. Oz. (15ml) tube with an integrated brush applicator for ease of use.
