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.
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.
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.
There are numerous peer-reviewed publications and an FDA monograph that provides clear evidence of the effectiveness of our formulation. We are happy to provide you with the abstracts of the peer-reviewed publications.
Your doctor may prescribe Formula 7® Solution for off-label use when they judge that it is medically appropriate for you.
