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.

Ask Your Doctor for Formula 3® Antifungal

Because it’s critical that any infection is properly and correctly diagnosed by a physician, we only make Formula 3® Antifungal available through your doctor’s office.

When you purchase Formula 3® Antifungal at your physician’s office, it is backed by an unconditional, patient-direct, money-back guarantee. If you are not completely satisfied with Formula 3®, simply call the toll-free 800 number on either the bottle or box for instructions on obtaining a full refund.

Is Formula 3® being replaced or will it continue to be available?

Formula 3® will continue to be available.  Thousands of patients have had excellent results with Formula 3® and continue to use it for treatment and prophylaxis.  We recognize this and plan to continue to manufacture this safe and effective treatment.

What’s the difference between Formula 3® and Formula 7®?

Formula 3®  is a mixture of 5 oils.  One of the oils, jojoba oil, is the vehicle that holds the drug, tolnaftate 1% USP, in solution (Tetra’s U.S. Patent # 4,810,498).  Formula 7®  is an oil in water microemulsion.  The oil phase is comprised of the jojoba oil with the tolnaftate in solution and tea tree oil to fortify the microemulsion with antifungal, antiseptic, germicidal and anti-bacterial properties.  The water phase contains N-acetyl-l-cysteine (NAC) and urea:  urea to hydrate, soften, and open keratin for better drug penetration; NAC to increase the flux of tolnaftate through the keratin to the site of involvement and provide bactericidal properties.  Formula 7®  is clear, paraben free, fortified with bactericidal agents, and packaged in a free-flowing tube for easy application.  Both Formula 3®  and Formula 7®, like all our products, are dye and fragrance-free.

Should I use Formula 7® instead of Formula 3®?

Formula 7® is a different approach to the delivery of tolnaftate to the site of involvement.  It is designed to be both a primary and a follow-up course of treatment if Formula 3® therapy was not effective.  Your pathology, sensitivity to ingredients, medical history, compliance, and personal preference are sure to be key factors in the doctor’s prescription of each treatment.

Is there medical evidence to support Formula 3® effectiveness?

The FDA monograph provides clear evidence of the effectiveness of our formulation.

Why Does The Label Say; "Not Effective On Scalp Or Nails"?

Your doctor may prescribe Formula 3® for off-label use when they judge that it is medically appropriate for you.
