Pregnancy-Lactation
Pregnancy: There are no available data in pregnant women to inform the drug-associated risk for major birth defects and miscarriage; in animal reproduction studies, no adverse effects on embryofetal development were seen at oral doses administered during period of organogenesis up to 18 times maximum recommended human dose (MRHD) in pregnant rats or subcutaneous doses administered during period of organogenesis up to 2 times the MRHD in pregnant rats or 4 times the MRHD in pregnant rabbits
Lactation: There is no information available on presence of drug in human milk, effects of drug on breastfed infant, or effects of drug on milk production; lack of clinical data during lactation precludes clear determination of risk of drug to infant during lactation; consider development and health benefits of breastfeeding along with mother’s clinical need for drug and any potential adverse effects on breastfed infant from drug or from underlying maternal condition

Mechanism of Action
Naftifine is a synthetic allylamine antifungal that selectively inhibits the enzyme squalene monooxygenase resulting in reduced synthesis of the primary sterol, ergosterol, within the fungal membrane. It appears to have both fungicidal and fungistatic activity.
