What is Guaifenesin DM?

Guaifenesin DM is a non-prescription combination medication that temporarily relieves cough and chest congestion due to cold, flu, hay fever, or allergies. The active ingredients in Guaifenesin DM are an expectorant (guaifenesin) and a cough suppressant (dextromethorphan).

Guaifenesin loosens phlegm and mucus in the lungs and so makes coughs more productive at clearing congestion.

Dexromethorphan is derived from opioids, but it is not an opioid. However, it works in much the same way as codeine to relieve coughing. It slows down nerve signals. As a cough treatment, codeine slows down the part of the brain responsible for producing the cough reflex.

Guaifenesin DM is taken as a tablet, softgel, or syrup every 12 hours to relieve cough and chest congestion. Guaifenesin DM should not be administered to children under the age of 12.

What are the side effects of Guaifenesin DM?

The most common side effects of Guaifenesin DM include but are not limited to dizziness, drowsiness, nausea, and vomiting.

Allergic reactions are rare, but discontinue Guaifenesin DM if you notice any sign of an allergic reaction such as rash, hives, facial swelling, or trouble breathing.

This is not a complete list of side effects that may occur. Consult with your physician about any concerns you may have with side effects.
