If you are unsure of whether a medication might impact your current blood pressure state, your physician or pharmacist are the first resources you should consult. Often, they will be able to recommend an alternative product that will not affect your blood pressure.

Mayo Clinic Q And A: Decongestants Sometimes Cause More Harm Than Good
DEAR MAYO CLINIC: Ive heard that nonprescription decongestants can have significant side effects. Is this true?
ANSWER: While many people rely on nasal decongestants to help ease symptoms of a cold or flu, these medications can sometimes cause more harm than good, especially if taken repeatedly. Examples of commonly used decongestants include phenylephrine and pseudoephedrine. Often, these ingredients are included in multi-symptom cold and flu preparations, such as Maximum Strength Mucinex D, Robitussin Multi-Symptom Cold, and Tylenol Sinus Congestion & Pain.
Taking a decongestant can temporarily ease congestion, but it can also create a slight increase in your blood pressure. If you already have high blood pressure, especially if its not controlled, this may be a concern. Decongestants also can interfere with the effectiveness of certain blood pressure medications. If youre on blood pressure medication, check with your doctor or pharmacist before taking a nasal decongestant.
Extended-release decongestants may be less likely to raise blood pressure than the immediate-release kind but can still cause problems. People who have conditions such as diabetes, benign prostatic hyperplasia , ischemic heart problems, thyroid disorders, glaucoma and seizures generally should avoid using nasal decongestants.
