Used to temporarily relieve symptoms associated with the common cold, seasonal allergies, hay fever, and other respiratory conditions, including nasal congestion, sinus congestion, postnasal drip, sneezing, runny nose, itchy throat, and chest congestion accompanied by productive cough.
Brompheniramine blocks histamine receptors to reduce allergic symptoms; Dextromethorphan suppresses the cough reflex in the brain to decrease coughing frequency; Guaifenesin works as an expectorant by thinning and loosening mucus in the airways, making it easier to clear through coughing.
