The manufacturer, Vicks, says "If pregnant or breast-feeding, ask a health professional before use." WebMD recommends taking DayQuil only when necessary due to "evidence for malformations." There is also evidence this combination of drugs has the potential to "reduce uterine blood flow causing fetal hypoxia."

While the FDA does not assign a pregnancy class to DayQuil itself, reports on the individual ingredients. Tests of dextromethorphan on chicken embryos show it causes abnormalities in development; however, there are no reports of controlled data from human pregnancy. Phenylephrine, the other category C ingredient in this preparation, receives its warning without controlled studies in either animals or human pregnancy. Doctors recommend DayQuil only when there is no other option and the benefits outweigh the risks.
