Dextromethorphan (DM), the d-isomer of the codeine analog levorphanol, is an active ingredient present in a variety of cough and cold remedies. Recently, data generated from a study in chick embryos were extrapolated to suggest that pregnant women should not use this drug because of the risk of birth defects. We conducted a controlled study of pregnant women who used DM, to examine the possible teratogenic risk in humans.
