Treatment
Changing your lifestyle can help control and manage high blood pressure. Your doctor may recommend that you make lifestyle changes including:
Eating a heart-healthy diet with less salt
Getting regular physical activity
Maintaining a healthy weight or losing weight if you’re overweight or obese
Limiting the amount of alcohol you drink
But sometimes lifestyle changes aren’t enough. If diet and exercise don’t help, your doctor may recommend medication to lower your blood pressure.
Medications
The type of medication your doctor prescribes for high blood pressure depends on your blood pressure measurements and overall health. Two or more blood pressure drugs often work better than one. Sometimes finding the most effective medication or combination of drugs is a matter of trial and error.
You should aim for a blood pressure treatment goal of less than 130/80 mm Hg if:
You’re a healthy adult age 65 or older
You’re a healthy adult younger than age 65 with a 10% or higher risk of developing cardiovascular disease in the next 10 years
You have chronic kidney disease, diabetes or coronary artery disease
Ask your doctor what your blood pressure treatment goal should be. Also, the ideal blood pressure treatment goal can vary with age and health conditions, particularly if you’re older than age 65.
Medications used to treat high blood pressure include:
Diuretics. Diuretics, sometimes called water pills, are medications that help your kidneys eliminate sodium and water from the body. These drugs are often the first medications tried to treat high blood pressure.
There are different classes of diuretics, including thiazide, loop and potassium sparing. Which one your doctor recommends depends on your blood pressure measurements and other health conditions, such a kidney disease or heart failure. Diuretics commonly used to treat blood pressure include chlorthalidone, hydrochlorothiazide (Microzide) and others.
A common side effect of diuretics is increased urination, which could reduce potassium levels. If you have a low potassium level, your doctor may add a potassium-sparing diuretic — such as triamterene (Dyazide, Maxide) or spironolactone (Aldactone) — to your treatment.
Angiotensin-converting enzyme (ACE) inhibitors. These medications — such as lisinopril (Prinivil, Zestril), benazepril (Lotensin), captopril and others — help relax blood vessels by blocking the formation of a natural chemical that narrows blood vessels.
Angiotensin II receptor blockers (ARBs). These medications relax blood vessels by blocking the action, not the formation, of a natural chemical that narrows blood vessels. ARBs include candesartan (Atacand), losartan (Cozaar) and others.
Calcium channel blockers. These medications — including amlodipine (Norvasc), diltiazem (Cardizem, Tiazac, others) and others — help relax the muscles of your blood vessels. Some slow your heart rate. Calcium channel blockers may work better for older people and people of African heritage than do ACE inhibitors alone.
Don’t eat or drink grapefruit products when taking calcium channel blockers. Grapefruit increases blood levels of certain calcium channel blockers, which can be dangerous. Talk to your doctor or pharmacist if you’re concerned about interactions.
