What is atropine, chlorpheniramine, hyoscyamine, phenylephrine, scopolamine?

Atropine, hyoscyamine, and scopolamine decrease the amount of nasal and respiratory secretions (release of fluids) in the body that may cause sneezing, runny nose, and postnasal drip.

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

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

Atropine, chlorpheniramine, hyoscyamine, phenylephrine, and scopolamine is used to treat symptoms of allergies, hay fever, and the common cold.

This medication may also be used for purposes other than those listed here.
