Unfortunately getting a cold during pregnancy is common, and the symptoms can be harder to alleviate when you are also dealing with pregnancy fatigue, body changes, and morning sickness.

Colds are their own special kind of hell during pregnancy, so it is not surprising that so many women want to know what cold remedies are safe during pregnancy.

So let’s get you some relief from your cough and cold symptoms!



Robitussin DM is safe to take during pregnancy. However, taking any medications during pregnancy is ultimately a personal decision after you have researched the information that is available and discussed any concerns you may have with your doctor or midwife.

DM stands for dextromethorphan and guaifenesin.

Dextromethorphan is a cough suppressant that is found in many over-the-counter cold and flu medications and has been used for decades.

Guaifenesin is an expectorant, also found in many over-the-counter cold medications.

This ingredient in Robitussin DM has also not been shown to cause any harm during pregnancy.

Guaifenesin helps to loosen phlegm and mucus, making it easier to cough up.

Both of these ingredients can actually help prevent your cold symptoms from progressing to severe congestion or even pneumonia.
