"Scientists at the National Institutes of Health report they have discovered in mouse studies that a small molecule released in the spinal cord triggers a process that is later experienced in the brain as the sensation of itch.

Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term animal studies to determine the carcinogenic potential of Ecoza topical foam have not been performed.
Oral administration of econazole nitrate in rats has been reported to produce prolonged gestation.
Use In Specific Populations
Pregnancy Category C
There are no adequate and well-controlled trials with Ecoza topical foam in pregnant women. Ecoza topical foam should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Econazole nitrate has not been shown to be teratogenic when administered orally to mice, rabbits or rats. Fetotoxic or embryotoxic effects were observed in Segment I oral studies with rats receiving 10 to 40 times the human dermal dose. Similar effects were observed in Segment II or Segment III studies with mice, rabbits and/or rats receiving oral doses 80 or 40 times the human dermal dose.
It is not known whether econazole nitrate is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when econazole nitrate is administered to a nursing woman. Following oral administration of econazole nitrate to lactating rats, econazole and/or metabolites were excreted in milk and were found in nursing pups.
Of the 173 subjects treated with Ecoza topical foam, 1% in the clinical trials, 2 subjects were 1217 years old. In a pediatric maximal use trial, Ecoza topical foam, 1% was applied once daily to eighteen subjects aged 12 to 17 years with interdigital tinea pedis for 28 days [see CLINICAL PHARMACOLOGY]. The safety findings for subjects 12 to 17 years were similar to those in adult population.
Of the 173 subjects treated with Ecoza topical foam, 1% in the adult clinical trials, 6 subjects were 65 years or older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects.This monograph has been modified to include the generic and brand name in many instances.
