Deltuss DMX

Dexchlorpheniramine is an antihistamine that helps reduce the effects of the natural chemical histamine in the body. Histamine can cause symptoms like sneezing, itching, watery eyes, and a runny nose.

Dextromethorphan is a cough suppressant. It works on the signals in the brain that cause the cough reflex.

Pseudoephedrine is a decongestant that narrows blood vessels in the nasal passages. When blood vessels are enlarged, it can lead to nasal congestion (a stuffy nose).

Deltuss DMX is a combination medicine used to treat a runny or stuffy nose, sneezing, itching, watery eyes, cough, and sinus congestion caused by allergies, the common cold, or the flu.

Deltuss DMX will not treat a cough that is caused by smoking, asthma, or emphysema.

Deltuss DMX may also be used for other purposes that are not mentioned in this medication guide.
