Medications and supplements that can raise your blood pressure

Medicines for a stuffy nose, called decongestants

Decongestants narrow blood vessels. This can reduce swelling in the nose area and other parts of the body. But it's harder for blood to go through a narrowed blood vessel. So blood pressure can go up. Decongestants are found in many cold and allergy medicines. Watch for any of these ingredients:

  • Pseudoephedrine.
  • Phenylephrine.

If you have high blood pressure, it's best to stay away from decongestants. If you have a stuffy nose, choose a cold or allergy medicine that says it's made for people with high blood pressure.
