What is guaifenesin?
Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.
Guaifenesin is used to reduce chest congestion caused by the common cold, infections, or allergies.
Guaifenesin may also be used for other purposes not listed in this medication guide.
