PSEUDOEPHEDRINE-DM-GUAIFENESIN

Pseudoephedrine is a decongestant that relieves nasal congestion by shrinking the blood vessels in the nasal passages. Dextromethorphan (DM) is a cough suppressant that reduces the urge to cough by affecting certain part of the brain. Guaifenesin is an expectorant that helps loosen congestion in the chest and throat. It works by making it easier to cough out through your mouth.
