What is J-Max DHC (dihydrocodeine and guaifenesin)?
Dihydrocodeine is a narcotic cough suppressant. It affects signals in the brain that trigger the cough reflex. Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth. The combination of dihydrocodeine and guaifenesin is used to treat cough and to reduce chest congestion caused by allergies, flu, or the common cold. Dihydrocodeine and guaifenesin will not treat a cough that is caused by smoking, asthma, or emphysema. Dihydrocodeine and guaifenesin may also be used for other purposes not listed in this medication guide.
