criptions during pregnancy in 1000 women living in Haute-Garonne, southwest
France, showed that 99% of the women received a prescription for at least
one drug during pregnancy with a mean of 13.6 medications per woman. 1.6% o
f women received one or more prescriptions of drugs from the US Food and Dr
ug Administration X category (fetal risk outweighs benefits). 59% of women
had a prescription of drugs from the D category (fetal risk but benefits ma
y be acceptable) and 79% of women were exposed to drugs for which informati
on about safety in pregnancy was not available from animal or human studies
