Guaifenesin Effects
Guaifenesin is known as an expectorant, which means that it helps loosen up any mucus trapped in the lungs. It does this by increasing the water content of the mucus, making it less viscous, Medications.com explains. It also helps stimulate the cough reflex, increasing the body's urge to cough up mucus.
Pseudoephedrine Effects
Pseudoephedrine is a medication, which causes the blood vessels within the nose to constrict, helping to relieve nasal congestion. In addition to being used to treat nasal and sinus congestion, pseudoephedrine is also used to treat congestion of the Eustachian tubes.
