General: If a reaction suggesting sensitivity or chemical irritation
should occur, use of the medication should be discontinued.
For external use only. Avoid introduction of econazole nitrate cream into the
eyes.
Carcinogenicity Studies: Long-term animal studies to determine
carcinogenic potential have not been performed.
Fertility (Reproduction): Oral administration of econazole nitrate
in rats has been reported to produce prolonged gestation. Intravaginal administration
in humans has not shown prolonged gestation or other adverse reproductive effects
attributable to econazole nitrate therapy.
Pregnancy: Pregnancy Category C. Econazole nitrate has not been
shown to be ter-atogenic when administered orally to mice, rabbits or rats.
Fetotoxic or embryotox-ic 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.
Econazole nitrate should be used in the first trimester of pregnancy only when
the physician considers it essential to the welfare of the patient. The drug
should be used during the second and third trimesters of pregnancy only if clearly
needed.
Nursing Mothers: It is not known whether econazole nitrate is
excreted in human milk. Following oral administration of econazole nitrate to
lactating rats, econazole and/or metabolites were excreted in milk and were
found in nursing pups. Also, in lactating rats receiving large oral doses (40
or 80 times the human dermal dose), there was a reduction in post partum viability
of pups and survival to weaning; however, at these high doses, maternal toxicity
was present and may have been a contributing factor. Caution should be exercised
when econazole nitrate is administered to a nursing woman.
