Available information has not established a clear pregnancy risk from guaifenesin, but pregnancy research is limited; discuss its potential benefits and risks with a healthcare professional. Discuss guaifenesin’s potential benefits and risks with your obstetrician or another qualified healthcare professional before using it during pregnancy. The FDA no longer uses the former letter categories for pregnancy risk. Information about guaifenesin use during pregnancy is limited, so discuss its potential benefits and risks with a healthcare professional. Some healthcare professionals may recommend guaifenesin for chest congestion when its expected benefit outweighs potential risk, particularly after the first trimester, but recommendations vary because pregnancy data are limited. Dosing depends on whether the product is immediate-release or extended-release. Follow the label for the exact product and confirm the dose with a healthcare professional during pregnancy; do not exceed the labeled maximum. Check the active ingredients before using any Mucinex product, because combination products may contain dextromethorphan, decongestants, pain relievers, or other medicines. Ask a healthcare professional whether each ingredient is appropriate during pregnancy. Always consult your obstetrician before taking any medication during pregnancy, as individual circumstances vary and they can recommend the safest treatment options for your specific situation.
