Does Pseudoephedrine Raise Blood Pressure?

Pseudoephedrine constricts blood vessels in the nose and sinuses. This shrinks swelling and drains fluids, letting you breathe easier again. Unfortunately, the drug doesn't affect only the head — it tightens blood vessels throughout the body. One pseudoephedrine side effect is a possible increase in blood pressure.

To keep your blood pressure in check, avoid over-the-counter decongestants and multisymptom cold remedies that contain decongestants — such as pseudoephedrine, ephedrine, phenylephrine, naphazoline and oxymetazoline. Also, check the label for high sodium content, which can also raise blood pressure.
