SYDENCOL (PhenylPropanolamine HCI + Chlorphenamine Maleate)
Phenylpropanolamine is a decongestant.
It works by constricting (shrinking) blood vessels (veins and arteries) in your body. Constriction of blood vessels in your sinuses, nose, and chest allows drainage of those areas, which decreases congestion.
Chlorphenamine maleate blocks the effects of histamine and so reduces symptoms like itchy, watery eyes, running or blocked nose, sneezing and rashes.
For the treatment of common colds, hay fever, sinus, nasal congestion, watery eyes, sneezing and related allergic symptoms.
