Pseudoephedrine and High Blood Pressure Interaction

In 2005, a study showed that pseudoephedrine increased systolic blood pressure and heart rate, but had no effect on diastolic blood pressure.1 They also found that higher doses and immediate-release formulations of pseudoephedrine were associated with higher blood pressures.1 In addition, the study revealed that patients with well controlled hypertension had higher systolic and diastolic blood pressures after taking immediate release pseudoephedrine formulations.1

What are safe alternatives to pseudoephedrine in patients with high blood pressure?

There are a few safe and effective alternatives to pseudoephedrine in patients with high blood pressure that can relieve nasal or sinus congestion symptoms. Placing a humidifier in the bedroom keeps moisture in the air, which helps prevent your nasal passages from drying out. Humidifiers can also help break up mucus and soothe inflamed nasal passageways.3 In addition, propping your head up on 2 pillows may help the mucus flow out of your nose and relieve some congestion. Saline sprays are also another safe option that can loosen congestion and improve drainage.3 If a patient with high blood pressure insists on taking a medication that includes pseudoephedrine, their pharmacist or physician will recommend the patient to monitor their blood pressure and take a sustained-release formulation to reduce the risk of increasing blood pressure.3

Next time you have sinus or nasal congestion, ask your physician before using pseudoephedrine if you have high blood pressure. Your local pharmacist can also help manage nasal congestion symptoms, provide valuable information regarding safer alternatives, and ensure optimal drug selection in patients with high blood pressure.
