Although the exact mechanism of action against fungi is not known, naftifine appears to interfere with sterol biosynthesis by inhibiting the enzyme squalene 2,3-epoxidase. This inhibition of enzyme activity results in decreased amounts of sterols, especially ergosterol, and a corresponding accumulation of squalene in the cells.

The most common adverse reaction (≥1%) is pruritus.

Pregnancy Category B. There are no adequate and well-controlled studies of Naftifine Cream in pregnant women. Because animal reproduction studies are not always predictive of human response, Naftifine Cream should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Naftifine Cream is administered to a nursing woman.

If redness or irritation develops with the use of Naftifine Cream treatment should be discontinued.

Pediatric Use: The safety and effectiveness of Naftifine Cream have been established in the age group 12-17 with interdigital tinea pedis and tinea cruris. Safety and effectiveness in pediatric patients <12 years of age have not been established. Geriatric Use: Clinical studies of Naftifine Cream did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
