Uses For guaifenesin and hydrocodone
Guaifenesin and hydrocodone combination is used to relieve cough and nasal congestion associated with the common cold.
Hydrocodone is a narcotic antitussive (cough suppressant). It acts directly on the cough center in the brain to relieve cough. Guaifenesin is used to help clear mucus or phlegm from the chest when you have congestion from a cold or flu. It works by thinning the mucus or phlegm in the lungs.
guaifenesin and hydrocodone is available only with your doctor's prescription.
