Can you take cold medication if you have high blood pressure?


Decongestants may aggravate your blood pressure and antihistamines may cause additive drowsiness. Check with your doctor to make sure your blood pressure is controlled well enough to take a decongestant like phenylephrine or pseudoephedrine for a few days until you are feeling better. A product is available without a decongestant called Coricidin® HBP which controls pain and allergy symptoms. If you decide to take an over-the-counter product, be sure to match your symptoms up to the product's relief description. Antihistamines like chlorpheniramine or diphenhydramine make you feel drowsier while taking your blood pressure medicine. You may feel drowsy or more tired when taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you.
