Pregnancy Teratogenic Effects. Teratology studies have been performed in rats using oral loperamide hydrochloride doses of 2.5 mg/kg/day, 10 mg/kg/day, and 40 mg/kg/day, and in rabbits using oral doses of 5 mg/kg/day, 20 mg/kg/day, and 40 mg/kg/day. These studies have revealed no evidence of impaired fertility or harm to the fetus at doses up to 10 mg/kg/day in rats (5 times the human dose based on body surface area comparison) and 40 mg/kg/day in rabbits (43 times the human dose based on body surface area comparison). Treatment of rats with oral doses of 40 mg/kg/day (21 times the human dose based on a body surface area comparison) produced marked impairment of fertility. The studies …
