Guaifenesin is a common expectorant found in many over-the-counter cough and cold medications. It works by thinning and loosening mucus in the respiratory tract, making it easier to cough up and clear the airways. Dextromethorphan and codeine are cough suppressants, while diphenhydramine is an antihistamine often used for its sedative effects.
