What decongestant can you take with high blood pressure

Decongestants can pose a dangerous risk to people with hypertension. Try these other steps to safely treat a cold or allergies.

Cold medicines are not off-limits if you have heart disease, but patients with high blood pressure, or hypertension, should check the label carefully when choosing a cold or allergy medicine.

That’s because decongestants such as pseudoephedrine, ephedrine, phenylephrine, naphazoline and oxymetazoline can increase your blood pressure and heart rate. Make sure the cold or allergy medication you plan to take is free of those ingredients.

Decongestants can also prevent your blood pressure medication from working properly. And always check the active and inactive ingredient lists, because many medications are high in sodium, which also raises blood pressure.

For allergy sufferers with heart disease, medicines such as Allegra, Zyrtec or Claritin should be safe. However, medicines containing decongestants — including Allegra-D, Zyrtec-D and Claritin-D — could increase your blood pressure and heart rate or interfere with your heart medication.

Managing a cold with hypertension

If you can’t take a decongestant because of high blood pressure, there are other ways to reduce your cold or allergy symptoms:

• Take Coricidin HBP, which is free of decongestants

• Drink plenty of fluids — including water, juice, tea and soup — to prevent dehydration and clear mucus from your lungs 

• Take a pain reliever such as Tylenol or Motrin for fever, sore throat, body aches and headache

• Flush your sinuses with a saline spray to relieve nasal congestion

• Soothe a sore or scratchy throat with lozenges

• Use a vaporizer or humidifier if necessary to boost humidity

• Get plenty of rest

• Return to your doctor after five to seven days to make sure you’re on the road to recovery

Before taking any new medication

Always check with your pharmacist before you take a new medication, whether it’s for a cold, allergies or something else, to find out if it is compatible with certain medical conditions and your current drug therapy.

If you have a heart condition, be sure to discuss all medication choices with your cardiologist before taking anything.

As cold and flu season rages on, health experts are warning people with high blood pressure to think twice before popping or pouring over-the-counter medications to relieve their symptoms.

Decongestants, a common ingredient in cold and flu drugs, constrict blood vessels to help relieve congestion. And constricted blood vessels can temporarily raise blood pressure levels and reduce blood flow in people with poor circulation. Decongestants may also interfere with the effectiveness of prescribed blood pressure medication, the American Heart Association says.

"It's kind of a general thing that blood vessel constrictors are not a good idea for people with high blood pressure,” Sandra J. Taler, a professor of medicine and physician in the Division of Nephrology and Hypertension at the Mayo Clinic, cautions. “And probably a lot of people don't know that.”

Oftentimes, however, it's not obvious what pills and syrups contain decongestants. If pseudoephedrine and phenylephrine are listed as ingredients, the medicine contains a decongestant, Taler says. The letters “CF” or “D” on the box or bottle is another signal that a decongestant is present, she adds.

People with high blood pressure should also be cautious of cold medicine combinations containing nonsteroidal anti-inflammatories (NSAIDs); Advil Cold & Sinus is one example. NSAIDs can counteract the effectiveness of high blood pressure medications, Taler explains.

What to take if you have high blood pressure

So what can you turn to? Taler points to guaifenesin (Mucinex) as an option if you need to thin and clear mucus. And dextromethorphan (Robitussin) can be used to suppress coughs. Even with these, be sure to avoid the “CF” and “D” varieties. Some drug manufacturers also make cold medicines specifically for people with high blood pressure; these are usually marked with “HBP” on the package.

But Ian K. Smith, a physician and wellness author, suggests that with all the combination therapies and confusing trade and generic names, it's a good idea to make a quick call to your doctor's office, to make sure you're in the clear — both for blood pressure and other side effects. And be sure to pay attention to dosing instructions, as many cold and flu medicines reduce alertness.

"What people have to understand is that even good medications that are helpful and useful can have side effects,” Smith says. And all too often, “people don't think of over-the-counter meds as a concern,” Taler adds.

Smith stresses the importance of hand hygiene during cold and flu season, as well as exercise and a healthy diet. Rest and plenty of fluids also help kick a cold, Taler says.
