It does many things, in order to achieve the goal of nasal decongestion. It acts by enhancing norepinephrine (noradrenaline) and epinephrine (adrenaline) or adrenergic activity by stimulating the α-adrenergic receptors. This induces vasoconstriction of the blood vessels in the nose, throat, and paranasal sinuses, which results in reduced inflammation (swelling) and mucus formation in these areas.

Basically it temporarily constricts blood vessels to allow for more "breathing room" so to speak in your nose and throat.

What is the difference between Sudafed and Sudafed pe?

The difference between Sudafed and Sudafed PE is that Sudafed contains pseudoephedrine and Sudafed PE contains phenylephrine. While phenylephrine doesn't work quite as well as a decongestant, it is the most common decongestant ingredient in cold and sinus formulations, due to the fact that people were using pseudoephedrine to make the illegal drug methamphetamine.


Can you take Sudafed and aspirin on the same day?

It all depends on the main ingredient in the Sudafed you are purchasing. The regular Sudafed which contains pseudoephdrine is safe to take with Dayquil. The Sudafed PE, which is now being sold can not be taken with Dayquil since Dayquil contains the same decongestant, phenylephrine as Sudafed PE.
