Tetra Antifungal Products
Formula 3 Antifungal

For over 50 years, the FDA has approved the use of tolnaftate for the treatment of athlete's foot and ringworm. Tolnaftate is the active ingredient in Formula 3 Antifungal.
The treatment is effective as a result of Tetra's invention of oil-soluble tolnaftate. Formula 3 was the first product available to patients utilizing this formulation which includes natural jojoba oil. The jojoba oil is quickly absorbed by the skin, which delivers the tolnaftate directly to the infected area.
