Stuffy nose? People with hypertension, diabetes, glaucoma, thyroid or prostate issues should ask their doctor before taking decongestants.

Got a cold that just won’t quit? Relieving sinus pressure with an over-the-counter decongestant is a safe choice for most people. But if you have a history of heart disease, high blood pressure, diabetes, glaucoma, thyroid or prostate issues, it’s best to consult your doctor before taking decongestants. Their active ingredients — pseudoephedrine and phenylephrine — work by constricting the blood vessels in the lining of the nose. This reduces swelling in the nasal passages, which allows you to breathe more easily. However, the nose isn’t the only place where blood vessels shrink. The drugs impact the entire body and could lead to a dangerous increase in blood pressure for some people. Though generally regarded as safe when taken as directed, over-the-counter decongestants have led to heart attacks, strokes, irregular heart rhythms and other cardiovascular problems. Other ways to ease a plugged-up nose include: using saline nasal spray, a neti pot and a humidifier, drinking warm liquids, and keeping your head slightly elevated when lying down.
