- Do not use this medication for any disorder other than that for which it was prescribed.
Carcinogenesis, Mutagenesis, Impairment Of Fertility
In a rat dermal carcinogenicity study, topical administration of sertaconazole nitrate cream for up to 102 weeks did not increase the number of neoplastic lesions compared to control animals, at sertaconazole nitrate doses of up to 800 mg/kg/day (approximately 200 times the maximum recommended human dose based on a body surface area comparison).
No clastogenic potential was observed in a mouse micronucleus test. Sertaconazole nitrate was considered nonclastogenic in the in vivo mouse sister chromatid exchange assay. There was no evidence that sertaconazole nitrate induced unscheduled DNA synthesis in primary rat hepatocyte cultures.
At oral doses up to 60 mg/kg/day (16 times the maximum recommended human dose based on a body surface area comparison), sertaconazole nitrate exhibited no toxicity or adverse effects on reproductive performance or fertility in male or female rats.
Use In Specific Populations
Pregnancy Category C
There are no adequate and well-controlled studies conducted with ERTACZO cream in pregnant women. ERTACZO cream should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Reproduction studies have not been performed with ERTACZO cream. Sertaconazole nitrate did not produce any evidence of maternal toxicity, embryotoxicity or teratogenicity in rats and rabbits at an oral dose of 160 mg/kg/day (40 times (rats) and 80 times (rabbits) the maximum recommended human dose based on a body surface area comparison). A reduction in live birth indices and an increase in the number of still-born pups were seen at doses of 80 and 160 mg/kg/day sertaconazole nitrate in an oral peri-and post-natal development study in rats.
It is not known if sertaconazole is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when prescribing ERTACZO cream, 2%, to a nursing woman.
The efficacy and safety of ERTACZO cream, 2%, have not been established in pediatric patients below the age of 12 years.
Clinical trials of ERTACZO cream, 2%, did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.This monograph has been modified to include the generic and brand name in many instances.
