Pregnancy: Studies in humans have not been done.
There was a slight increase in resorptions and decrease in number of live fetuses in female Wistar rats given 40 mg/kg, with no effects seen at doses of 0, 10 or 20 mg/kg; there was no evidence of teratogenicity. There was a dose-related increase in the number of resorptions in New Zealand rabbits given doses of 0, 2.5 or 10 mg/kg from day 6 to day 18 of pregnancy, with a corresponding decrease in number of live births; there was no evidence of teratogenicity.
Breast-feeding: It is not known whether Flunarizine is distributed into breast milk in humans; however it is distributed into the milk of dogs, at concentrations much higher than in plasma.
