What is dexchlorpheniramine, methscopolamine and pseudoephedrine?

Dexchlorpheniramine is an antihistamine. It works in your body against a natural chemical called histamine. Dexchlorpheniramine prevents sneezing; itchy, watery eyes and nose; and other symptoms of allergies and hay fever.

Methscopolamine decreases the amount of nasal and respiratory secretions (release of fluids) in the body that may cause sneezing, runny nose, and postnasal drip.

Pseudoephedrine is a decongestant. It works by shrinking blood vessels in the body, reducing blood flow and allowing nasal passages to open up.

Dexchlorpheniramine, methscopolamine and pseudoephedrine is used to treat nasal congestion and sinusitis (swelling of the sinuses) associated with allergies, hay fever, and the common cold.

Dexchlorpheniramine, methscopolamine and pseudoephedrine may also be used for purposes other than those listed here.
