Brompheniramine is an antihistamine. It works against the naturally occurring chemical
histamine in your body. Brompheniramine prevents sneezing; itchy, watery eyes and nose; and other
symptoms of allergies and hay fever.
Phenylpropanolamine 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.
Brompheniramine and phenylpropanolamine is used to treat nasal congestion and sinusitis
(inflammation of the sinuses) associated with allergies, hay fever, and the common cold.
Phenylpropanolamine, an ingredient in this product, has been associated with an increased
risk of hemorrhagic stroke (bleeding into the brain or into tissue surrounding the brain) in women.
Men may also be at risk. Although the risk of hemorrhagic stroke is low, the U.S. Food and Drug
Administration (FDA) recommends that consumers not use any products that contain
phenylpropanolamine.
Brompheniramine and phenylpropanolamine may also be used for purposes other than those
listed in this medication guide.
