title: Associations between drugs administered during pregnancy and congenital abnormalities of the fetus.
abstract: In a retrospective study to compare the drug consumption during pregnancy of mothers of infants with congenital abnormalities and of those without, over 97% of 1,369 mothers took prescribed drugs and 65% self-administered drugs. Significantly more mothers of infants with congenital abnormalities took aspirin, antacids, dextroamphetamine, phenobarbitone, sodium amytal, other barbiturates, cough medicines, iron, sulphonamides, and nicotinamide than mothers in the control group. However, most mothers taking analgesics, antacids, appetite suppressants, barbiturates, cough medicines, iron, sulphonamides, and vitamins produced normal infants. Any teratogenic effect of these drugs is therefore one of low potency. On the other hand, deficiencies such as those of ascorbic acid and folic acid may have a teratogenic effect. There is need for caution in presuming teratogenic effects on the basis of the associations shown here. During pregnancy, however, it would appear wise to avoid the administration of any drug which carries a suspicion of teratogenicity unless that drug is specifically indicated, and self-medication with common household remedies such as aspirin and antacids should be avoided. These recommendations would also apply to any woman of childbearing age in whom conception is likely.
