Decongestants & High Blood Pressure: Understanding the Risks

People with high blood pressure are often frustrated by the warning labels on over the counter decongestants. Many patients question why decongestants are dangerous for people with hypertension.

Misconceptions

• Although people with colds often notice an increase in nasal discharge, a lot of nasal congestion is caused by the dilation of blood vessels in the nasal passages.

Function

• Nasal decongestants constrict the blood vessels in the nasal passages. This reduces swelling and makes breathing through the nose easier.

Effects

• Since nasal decongestants constrict blood vessels, they will also raise blood pressure.

Considerations

• Nasal decongestants can increase heart rate, which is also undesirable for people with high blood pressure.

Prevention/Solution

• People with high blood pressure should ask their doctor or pharmacist for recommendations on over-the-counter products.
