Chlorpheniramine and phenyltoloxamine are antihistamines. They block the effects of the naturally occurring chemical histamine in the body. Chlorpheniramine and phenyltoloxamine prevent sneezing; itchy, watery eyes and nose; and other symptoms of allergies and hay fever. Phenylephrine is a decongestant. It constricts (shrinks) blood vessels (veins and arteries). This reduces the blood flow to certain areas and allows nasal passages to open up. Chlorpheniramine, phenyltoloxamine, and phenylephrine is used to treat nasal congestion and sinusitis (inflammation of the sinuses) associated with allergies, hay fever, and the common cold. Chlorpheniramine, phenyltoloxamine, and phenylephrine may also be used for purposes other than those listed in this medication guide.
