Here’s how the different kinds of blood pressure medicine can help and which ones may be best for you.

Blood Pressure Numbers: Two Numbers You need to Know

First, let’s start with what your blood pressure numbers mean.

Your blood pressure is measured with two numbers, and that simple test is an easy, quick measure of heart health, says MetroHealth pharmacist Shelby Clapacs. Blood pressure is the force of your blood pushing against your vessels.

The top number (systolic) is the pressure when your heart beats.
The bottom number (diastolic) is the pressure when your heart relaxes

Blood Pressure: What’s Normal?

120/80 or under is normal
120-129/80 is elevated
130-39/80-89 is stage 1 hypertension/high blood pressure
140+/90+ is stage 2 hypertension/high blood pressure
180+/120+ is a hypertensive crisis (meaning you should call 911)

When Would You Need Blood Pressure Medicine?

If you’re in the “elevated” range, your doctor will probably talk to you about some lifestyle changes. This could include:

Physical activity
Changing your diet
Quitting smoking
Cutting back on caffeine and alcohol
Reducing stress
Getting more sleep

If you enter into stage 1 high blood pressure, your doctor may suggest medicine. Every circumstance is different. Your doctor may give you a certain amount of time to keep trying lifestyle changes first. However, by stage 2, medicine is very important.

Types of Blood Pressure Medications

There are a handful of medicines your doctor might prescribe. Medicines work differently for different people. Some people may need to be on more than one.

Diuretics (furosemide, hydrochlorothiazide): Also called water pills, these medicines help get rid of excess water and salt, lowering blood pressure. You may have to go to the bathroom more if you take a diuretic and you have to be careful not to become dehydrated.
Beta-blockers (metoprolol, carvedilol): These lower your heart rate by making your heart beat more slowly. Your blood vessels can relax, which lowers blood pressure. Side effects include tiredness, dizziness, insomnia, and constipation.
ACE inhibitors (lisinopril): These stop a chemical that narrows your blood vessels, helping them stay more open. Some people develop a dry, hacking cough. If this happens to you, your doctor will switch you to another blood pressure medication.
ARBs (losartan, valsartan): These work on the same chemical as ACE inhibitors, but in a slightly different way. Your doctor will monitor your kidney function closely on an ARB.
Calcium channel blockers (amlodipine): These prevent calcium from entering your heart muscle, keeping your vessels more open. Side effects include swelling in hands and lower legs. If this happens, your doctor might decrease your dose or switch to a different class.
