... days tablets or spray can be administered to hypertensive patients safely
Decongestants (eg phenylephrine) work by constricting blood vessels, which in turn shrinks the swelling in the nose and opens nasal passages. While this constriction of blood vessels helps alleviate congestion, it may raise high blood pressure temporarily after each dose.
It is important that patients with high blood pressure manage their hypertension with proper medical treatment and seek a pharmacists advice for cold and flu treatments.
Decongestants should not be taken by hypertensive patients.
