Can a Sinus Infection Raise Your Blood Pressure?
A sinus infection, or sinusitis, does not usually directly cause high blood pressure. However, illness-related factors such as pain, stress, poor sleep, dehydration, and certain medications may temporarily affect your blood pressure.
If you have high blood pressure and develop a sinus infection, knowing which factors and medications may affect your readings can help you make safer treatment decisions.
Can a Sinus Infection Cause High Blood Pressure?
A sinus infection is not considered a direct cause of chronic high blood pressure. However, the discomfort and changes that occur during an illness can temporarily raise your readings.
For example, blood pressure may rise when you are experiencing:
- Pain or facial pressure
- Stress or discomfort
- Poor sleep because of congestion or coughing
- Dehydration
- Fever or illness
- Certain over-the-counter medications
These temporary changes do not necessarily mean that you have developed hypertension.
If your blood pressure remains elevated after your sinus symptoms improve, it should be evaluated separately rather than automatically attributed to sinusitis.
What Sinus Medicines Can Raise Blood Pressure?
Some over-the-counter sinus and cold medications can affect blood pressure.
Some decongestants, including pseudoephedrine, can narrow blood vessels and may increase blood pressure in some people. Some pain relievers, including NSAIDs such as ibuprofen and naproxen, may also increase blood pressure in certain individuals.
If you have hypertension, talk with your healthcare professional before taking a decongestant or combination cold and sinus medication. Check the active ingredients on combination products because they may contain more than one medication that can affect blood pressure.
What Can You Take for a Sinus Infection If You Have High Blood Pressure?
Having high blood pressure does not mean you cannot treat sinus symptoms. The appropriate treatment depends on the cause of your symptoms, your medical history, and any medications you already take.
Options may include:
- Saline nasal spray or irrigation: Saline can help loosen mucus and moisturize nasal passages. If you use a nasal irrigation device, use distilled, sterile, or previously boiled and cooled water.
- Humidified air: Moist air may help reduce nasal dryness and irritation.
- Condition-specific treatment: If allergies, nasal inflammation, nasal polyps, or another underlying condition is contributing to your symptoms, your healthcare professional may recommend treatment directed at that cause.
Not every sinus infection requires antibiotics. Treatment depends on whether the infection is viral or bacterial, how long symptoms have lasted, and how severe they are.
How Long Does Blood Pressure Stay High During a Sinus Infection?
There is no specific amount of time that blood pressure will remain elevated during a sinus infection. If higher readings are related to temporary factors such as illness or medication, they may improve as those factors resolve.
However, repeatedly high blood pressure readings should not automatically be attributed to sinusitis.
If you're monitoring your blood pressure at home, take readings under consistent conditions and keep a record to share with your healthcare professional. Home blood pressure monitoring is an important part of evaluating and managing hypertension.
When Is High Blood Pressure an Emergency?
Blood pressure can fluctuate during an illness, but very high readings should not automatically be attributed to a sinus infection. If your blood pressure is higher than 180/120 mm Hg, wait at least one minute and check it again. If it remains above 180/120 mm Hg, contact a healthcare professional promptly. If accompanied by chest pain, shortness of breath, weakness or numbness, significant vision changes, difficulty speaking, or other concerning symptoms, call 911. These symptoms may indicate a medical emergency requiring immediate evaluation.
When Should You See an ENT Specialist for Sinus Symptoms?
Consider seeing an ear, nose, and throat (ENT) specialist if your sinus symptoms are persistent, severe, worsening, or keep coming back.
An ENT specialist can evaluate symptoms such as:
- Ongoing nasal congestion
- Facial pressure or pain
- Recurrent sinus infections
- Difficulty breathing through your nose
- Postnasal drainage
- Reduced sense of smell
Persistent symptoms may be related to chronic sinusitis, allergies, nasal polyps, a deviated septum, or another nasal or sinus condition. An ENT evaluation can help identify the underlying cause and determine appropriate treatment.
