Blood Pressure Medications
Cetirizine and pseudoephedrine may make blood pressure medications less effective, possibly causing high blood pressure (hypertension). This is due to the pseudoephedrine component of the drug. If you take high blood pressure medications, check with your healthcare provider before taking cetirizine and pseudoephedrine, or try plain Zyrtec® instead, which does not contain pseudoephedrine and does not increase blood pressure.
