Is it true that Over-the-counter nasal sprays lower a person's blood pressure?
Partly. One small 45-patient study of intranasal mometasone in allergic rhinitis reported significantly lower daytime blood pressure after four weeks, while a case report shows a nasal-spray vasoconstrictor (naphazoline) raising blood pressure in overdose. Neither settles whether over-the-counter nasal sprays generally lower blood pressure.
