Ask the doctor: Can allergies cause high blood pressure?

Although allergies don’t usually directly increase blood pressure, they can contribute indirectly to high blood pressure in two very different ways. Decongestants commonly used by people with allergies, such as pseudoephedrine (Sudafed, Actifed, others) and phenylephrine (Sudafed PE), constrict small blood vessels in the nose.
