Some Nyquil products such as Nyquil Liquid contain some percentage of alcohol, and considering some of the side effects of the drug, it is wise to wonder if you can take it while pregnant. Now to answer your question “can I take Nyquil while pregnant?” Taking Nyquil while you’re pregnant, could be safe, however, this depends on the type of Nyquil product you’re using.

Why You Should Not Take Nyquil When Pregnant 

Just as we’ve said, the only Nyquil products that you shouldn’t take while pregnant, are those containing alcohol and phenylephrine. The reason phenylephrine is not a safe drug component for pregnant women is that it is a decongestant, and as such can narrow your blood vessels to prevent sneezing, coughing, and runny nose.

And while all these sound like just the relief you need, if you’re pregnant, especially in your first trimester, the narrowing of your blood vessels by phenylephrine, can also reduce the amount of oxygen circulating in your body, therefore leading to decreased supply of oxygen for your developing baby.

A decrease in oxygen supply can affect the development of a fetus, which may result in certain birth defects or death of the fetus. Nevertheless, no matter what Nyquil product you intend to use, always get confirmation from your doctor.
