What to take for sinus congestion with high blood pressure

As many over-the-counter decongestants get a new ingredient, you might want to look for alternatives.

For nasal congestion due to colds and allergies, millions of Americans reach for an over-the-counter decongestant to clear a stuffy nose. Some read the warning label: "Do not use this product if you have heart disease, high blood pressure, thyroid disease, diabetes, or difficulty in urination due to enlargement of the prostate gland unless directed by a doctor." Few heed it.

But it might be good to pay attention to the decongestant's warning. Many of your favorite products containing a decongestant are no longer so easily available on pharmacy shelves. For example, products containing pseudoephedrine, the active ingredient in Sudafed and many other non-prescription decongestants, now are purchased "behind the counter." You don't need a prescription, but you do have to ask a pharmacist or clerk for them and show an ID or sign a log.

Fearing that customers will shy away from asking a pharmacist or clerk for these products, some drug companies are replacing pseudoephedrine with another over-the-counter decongestant called phenylephrine.

Is phenylephrine just like pseudoephedrine? Regarding its effectiveness as a treatment for nasal congestion, the answer is no. In fact, some research has found that at the current recommended doses of phenylephrine it offers minimal symptom improvement. It may be safer for people with high blood pressure and heart disease, but there is not enough research to be certain.

Decongestant effects beyond the nose

A stuffy nose is a hallmark of the common cold and allergic rhinitis. Chalk this symptom up to the body's immune response.

When you have a cold, virus-infected cells in the nose, sinuses, and throat attract a flood of white blood cells. These infection fighters churn out substances that kill the cold virus but also swell nasal membranes and make the body produce extra mucus.

In allergic rhinitis, the immune cells trigger the same type of response in the nose, sinuses and throat.

Pseudoephedrine constricts blood vessels in the nose and sinuses. This shrinks swelling and drains fluids, letting you breathe easier again. Unfortunately, the drug doesn't affect only the head — it tightens blood vessels throughout the body.

One pseudoephedrine side effect is a possible increase in blood pressure. In general, this increase is minimal in people with controlled high blood pressure. But prior studies found a small percent of people had marked increases in blood pressure. If you have high blood pressure and need to take pseudoephedrine you should have your blood pressure checked more often.

The FDA says that pseudoephedrine is safe when taken as directed. Indeed, millions of people use it each year without any dire consequences. That doesn't mean it's risk free. Over the years, there have been reports of heart attacks, strokes, disturbed heart rhythms, and other cardiovascular problems linked with use of pseudoephedrine.

Alternatives to decongestants

Alternatives to oral decongestants are available. In the drug realm, antihistamines such as diphenhydramine (Benadryl), chlorpheniramine (Chlor-Trimeton), cetirizine (Zyrtec), and loratadine (Claritin) can help with a stuffy nose are safe for the heart.

Nasal sprays deliver a decongestant right where you need it. In theory, this should minimize cardiovascular effects. However, nasal decongestant sprays should be used only for several days because it can lead to rebound nasal congestion.

If you want to avoid medications altogether, you can try a variety of natural decongestants to clear your head. Breathe Right nasal strips may help you breathe better at night. A steamy shower or a hot towel wrapped around the face can relieve congestion. Drinking plenty of fluids, especially hot beverages, keeps mucus moist and flowing. Some people swear by spicy foods, and we would be remiss if we did not mention chicken soup.

To learn more about blood pressure levels, see the chart below.

Know Your Blood Pressure (BP)

Select where you blood pressure falls to understand more about you blood pressure and what you can do to improve. (As a reminder, systolic is the top number and diastolic is the bottom number of a BP reading).

Classification of Blood Pressure (Hypertension)1

Blood pressure can be grouped into different categories: normal, elevated, stage 1, stage 2, and hypertensive crisis.

Normal

Blood pressure is normal when numbers are less than 120/80 mm Hg.

Elevated

Blood pressure is elevated when systolic blood pressure (SBP) ranges from 120-129 mm Hg AND diastolic blood pressure (DBP) is less than 80 mm Hg. Non-medical therapy, such as heart-healthy diet and increased physical activity, is preferred at this stage.

Hypertension Stage 1

Stage 1 is when systolic blood pressure (SBP) ranges from 130-139 mm Hg OR when diastolic blood pressure (DBP) ranges from 80-89 mm Hg. At this stage, doctors may consider prescribing blood pressure-lowering medication in addition to lifestyle changes (improved diet and exercise). The doctor’s decision to prescribe medication will depend on your risk of atherosclerotic cardiovascular disease (ASCVD), such as heart attack or stroke.

Hypertension Stage 2

Stage 2 is when systolic blood pressure (SBP) is greater than or equal to 140 mm Hg OR when diastolic blood pressure (DBP) is greater than or equal to 90 mm Hg. At this stage, doctors are likely to prescribe a combination of blood pressure-lowering medications with lifestyle changes.

Hypertensive Crisis

If your blood pressure is more than 180/120 mm Hg, and you are NOT experiencing any other symptoms, it is classified as an hypertensive urgency, and you should immediately seek medical assistance.

If your blood pressure is more than 180/120 mm Hg AND you are experiencing signs and symptoms of target organ damage (shortness of breath, chest pain, back pain, headache, numbness, change in vision, loss of kidney function, and difficulty speaking), it is classified as an hypertensive emergency, and you should call 911 immediately.
