guaifenesin + pseudoephedrine hydrochloride

Guaifenesin + pseudoephedrine hydrochloride is an oral combination drug used to relieve symptoms associated with upper respiratory tract conditions, such as the common cold, allergies (hay fever), and other breathing illnesses. Guaifenesin acts as an expectorant by thinning and loosening mucus in the airways, making it easier to clear congestion. Pseudoephedrine is a sympathomimetic decongestant that works by constricting blood vessels in the nasal passages, thereby reducing swelling and congestion. This combination does not treat infections but provides symptomatic relief from cough with mucus, runny or stuffy nose, sneezing, sinus pain, watery eyes, and chest congestion. It is available over-the-counter in various dosage forms including tablets (regular and extended-release), capsules, and liquids. The product is marketed under numerous brand names worldwide.
