Guaifenesin is an expectorant used to relieve chest congestion by loosening and thinning mucus in the airways, making it easier to cough up and clear the respiratory passages. It is commonly found in over-the-counter medications used for treating colds, coughs, and other respiratory conditions such as bronchitis. Guaifenesin works by decreasing the viscosity of mucus, allowing the cilia in the respiratory tract to expel mucus more effectively. It is often combined with other active ingredients, such as decongestants or antihistamines, in multi-symptom cold remedies.
