When sinus congestion makes it difficult to breathe comfortably, an over-the-counter medicine can seem like the easiest solution.

But people with high blood pressure should pay attention to the ingredients in these products.

Some common sinus and cold medicines can affect blood pressure.

Decongestants Are the Main Concern

Decongestants reduce nasal swelling by narrowing blood vessels.

That action can also increase blood pressure. Common ingredients include pseudoephedrine and phenylephrine.

The concern is greater for people whose blood pressure is already high or poorly controlled.

Combination Products Need Extra Attention

Some products contain multiple active ingredients. A person may think they are taking a simple sinus remedy without realizing that the product contains a decongestant.

Always read the active ingredients before taking an OTC product.

If you take prescription blood pressure medication, ask your doctor or pharmacist whether the sinus product could interfere with your treatment.

What Alternatives Exist?

Depending on the cause of your symptoms, options may include saline nasal sprays or other treatments recommended by a healthcare professional.

The AHA/ACC hypertension guideline recommends considering alternatives to decongestants when appropriate, particularly for people with severe or uncontrolled hypertension.

Monitor Your Blood Pressure

If you have hypertension, continue monitoring your blood pressure according to your healthcare professional's advice.

If you notice a significant change after starting a new medicine, do not ignore it.

Final Thoughts

Treating sinus congestion is important, but choosing the right medicine matters too.

If you have high blood pressure, check the ingredients, avoid self-treating with potentially problematic medicines, and ask a healthcare professional when you are unsure.
