Animal studies of oral administration of 10 to 30% daily caloric intake (DCI) of this product during organogenesis showed reduced body weight gain which was considered specific to taste aversion related decreases in food consumption. The no adverse effect level (NOAEL) for the maternal toxicity was 10% of DCI; at approximately 35% DCI increased skeletal malformations, decreased litter weights, and reduced number of viable litters were seen; these were associated with maternal reduced body weight gains. At 50% DCI reduced birthweights and delayed sexual maturation of pups was seen but was considered secondary to reduced maternal body weight gain. There are no controlled data in human pregnancy. The background birth defect and miscarriage risk for the indicated population is not known. In the US general population, the estimated major birth defect risk is 2 to 4% and the miscarriage risk is 15 to 20%.
