WebMD Second Opinion
Got a health question? Get answers provided by leading organizations, doctors, and experts.
First things first: Always check with your doctor or pharmacist before you start taking anymedication -- for allergies or anything else. That's true for herbs and supplements, too.
Antihistamines are the most common medication for allergies. The good news is that most of them seem to be safe if you have high blood pressure -- but again, ask to make sure.

Don't take decongestants unless your doctor tells you otherwise. They may increase blood pressure. They also may keep some high blood pressure drugs from working the way they should.
Watch out for combination medications for allergies that include decongestant ingredients. That includes allergy drugs as well as many remedies for cold, flu, and sinus problems. A pharmacist can check the ingredients for you.
