Promethazine is the combination of antihistamine and
decongestant (Pseudoephedrine) given to treat and relieve symptoms of
seasonal allergies, common cold and flu as well as upper respiratory
tract. The antihistamine in Promethazine relieves the symptoms of seasonal
allergies and hay fever such as itchy, runny nose, sneezing, and watery
eyes as well as symptoms of allergic reactions like hives or swelling. The
decongestant (Pseudoephedrine) in Promethazine deals with constricting
the blood vessels, which in turn reduces the blood, flow to the nasal
passages thereby improving the flow of air and reducing nasal
secretions. Main ingredients in Promethazine are Promethazine + Phenylephrine Hydrochloride.
