Pregnancy & Lactation
Pregnancy
Oral doses of terbinafine hydrochloride up to 300 mg/kg/day (in terms of mg/m2/day equivalent to 146 and 329 times the maximum potential exposure at the recommended topical human dose*) during organogenesis in rats and rabbits, respectively, were not teratogenic
Similarly, a subcutaneous study in rats at doses up to 100 mg/kg/day (in terms of mg/m2/day equivalent to 49 times the maximum potential exposure at the recommended topical human dose*) and a percutaneous study in rabbits, including doses up to 150 mg/kg/day (in terms of mg/m2/day equivalent to 329 times the maximum potential exposure at the recommended topical human dose*), did not reveal any teratogenic potential; there are, however, no adequate and well-controlled studies in pregnant women
Because animal reproduction studies are not always predictive of human response, drug should be used only if clearly indicated during pregnancy
Lactation
Absorption from topical application limited; because of the small amount of data on human neonatal exposure, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother; nursing mothers should avoid application of drug to the breast

A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
