Luliconazole topical Pregnancy Warnings

Animal studies have failed to reveal evidence of adverse developmental effects with subcutaneous doses up to 3 (rats) and 24 (rabbits) times the maximum recommended human dose (MRHD). In rats, no therapy-related effects on maternal toxicity or malformations were observed at 25 mg/kg/day (3 times the MRHD based on body surface area [BSA] comparisons); while increased incidences of skeletal variation (14th rib) were seen at 25 mg/kg/day, no therapy-related effects on skeletal variation were seen at 5 mg/kg/day (0.6 times the MRHD based on BSA comparisons); with maternal toxicity present, embryofetal toxicity (increased prenatal and postnatal pup mortality, reduced live litter sizes) was seen at 25 mg/kg/day. In rabbits, no therapy-related effects on maternal toxicity, embryofetal toxicity, or malformations were observed at 100 mg/kg/day (24 times the MRHD based on BSA comparisons). There are no controlled data in human pregnancy.
