Maxifed DMX

Dextromethorphan is a medicine that stops coughing. It works on the brain to reduce the urge to cough.

Guaifenesin is a medicine that helps clear congestion in your chest and throat, making it easier to cough up mucus.

Pseudoephedrine is a medicine that reduces swelling in the blood vessels of the nasal passages. Swollen blood vessels can lead to a stuffy nose.

Maxifed DMX is a combination medicine used to relieve cough, stuffy nose, sinus congestion, and chest congestion caused by allergies, the common cold, or the flu.

Maxifed DMX will not treat a cough caused by smoking, asthma, or emphysema.

Maxifed DMX may also be used for other reasons not mentioned in this medication guide.
