Uses For hydrocodone, pseudoephedrine, and guaifenesin
Hydrocodone, pseudoephedrine, and guaifenesin combination is used to relieve cough and nasal congestion (stuffy nose) caused by the common cold.
Hydrocodone is a narcotic cough suppressant. It acts directly on the cough center in the brain to relieve cough. Pseudoephedrine is a decongestant, which decreases nasal congestion by narrowing the blood vessels and reducing blood flow to the nasal passage. 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.
When hydrocodone is used for a long time, it may become habit-forming. This could cause mental or physical dependence. Physical dependence may lead to unwanted withdrawal effects if treatment is stopped suddenly. Talk to your doctor if you have questions.
Hydrocodone, pseudoephedrine, and guaifenesin is available only with your doctor's prescription.
