Guaifenesin is an expectorant that, when combined with DXM, produces coughs that are more productive. It works by pulling water into the bronchi, lubricating air passages and thinning mucus.

Pseudoephedrine is a decongestant that’s useful for allergy- and cold-related congestion. It works by constricting blood vessels in the nasal passages, leading to better breathing.
