Medicines help lower blood pressure. When blood pressure is high, it starts to damage the blood vessels, heart, and kidneys. This can lead to heart attack, stroke, kidney disease, and other problems.

When you have high blood pressure, you don't usually feel sick. It can be hard to think about taking your pills when you don't feel sick. But taking them exactly as directed helps lower your risk for more serious problems.

Medicines control—but don't cure—most cases of high blood pressure. So you will need to take them for the rest of your life. Many people need to take more than one kind of pill to control their blood pressure. The types of blood pressure medicines include:

• Reference Diuretics. These pills cause the kidneys to remove more Reference sodium Opens New Window and water from the body. As a result, there is less blood circulating through the body. And that lowers blood pressure, especially Reference systolic Opens New Window blood pressure. Diuretics are often combined with other blood pressure medicines.
• Reference ACE inhibitors. These drugs block an enzyme needed to form a substance that causes blood vessels to narrow. As a result, blood vessels relax and widen. This makes it easier for blood to flow through the vessels, which reduces blood pressure. Also, these drugs increase the release of water and sodium to the urine, which also lowers blood pressure.
• Reference ARBs. These block the action of a hormone that causes blood vessels to narrow. These drugs also increase the release of sodium and water into the urine.
• Reference Beta-blockers. These pills lower the heart rate, the amount of blood the heart pumps out with each beat, and the force of the heartbeat, all of which lower blood pressure.
• Reference Calcium channel blockers. These work by reducing the amount of narrowing of the blood vessels caused by high blood pressure. This makes it easier for blood to flow through the vessels and lowers blood pressure.
• Reference Other medicines including alpha-blockers and vasodilators. These work by opening up the blood vessels. This makes it easier for blood to flow and lowers blood pressure.
• Reference Direct renin inhibitors. These block the enzyme renin from starting a process that helps regulate blood pressure. As a result, blood vessels relax and widen.

If you don't take your medicines properly, your blood pressure may not be controlled. This can lead to:

• Heart attack.
• Stroke.
• Kidney disease.
• Eye damage (retinopathy).
• Reference Peripheral arterial disease Opens New Window.

It can take some time to find the right combination of medicines with the fewest side effects. Take your medicines exactly as your doctor tells you to. And don't be surprised if your doctor decides to change your medicines. Just keep following his or her directions.

Some medicines shouldn't be combined with other prescription or nonprescription medicines. Make sure your doctor knows all of the medicines you are taking.

Medicines work really well to control high blood pressure in most people. But they won't work if you don't take them as directed. Here's how you can get started on taking your medicines properly.

Get organized

It may not be too hard for most people to remember to take just one pill a day. But if you start adding more pills—pills that you need to take at different times and in different doses—it can get confusing.

A key to taking your medicines properly is to stay organized:

• Make a list. Make a written or typed list of every medicine you take, including things like aspirin and vitamins. Keep it up to date. Take a copy with you every time you go to the doctor. Use a form (What is a Reference PDF Opens New Window document?). Include space to write down any side effects you have.
• Make a schedule. Make a written or typed daily schedule of when you should take each of your medicines. Put it where you can easily see it every day—on the door of your medicine cabinet, for example. Use a daily planner (What is a Reference PDF Opens New Window document?). Take it along when you travel.
• Use a pillbox. Pillboxes can really help you keep track of your pills. Some hold a week's worth, with separate compartments for morning, noon, evening, and bedtime.
• Use alarms. Set your computer, wristwatch, or cell phone to beep when it's time to take your pills.
• Simplify. Ask your doctor if you can make your pill schedule simpler. For example, maybe you could take one longer-acting pill every day instead of several shorter-acting ones.
• Control costs. Compare prices between several drugstores, and consider mail-order drugstores. Ask your doctor if there is a generic brand you can take to save money.

Become an expert

The more you know about your medicines, the easier it will be to stay on your schedule and take your pills properly.

• Know your medicines. Have your doctor clearly explain what each medicine does. Write down both the Reference brand Opens New Window and Reference generic Opens New Window names. Have your doctor check the list. You can use this list to verify that the medicines you get from the pharmacy are correct.
• Store medicines properly. Your doctor or pharmacist can tell you how to store your medicines. Don't let your medicines get too hot or too cold. Always store them out of the reach of children.
• Watch for side effects. Ask your doctor or pharmacist about what side effects to expect. Write them down if you don't think you'll be able to remember them. Be sure to tell your doctor if you have side effects.
• Have a plan for missed doses. Talk with your doctor about what you should do if you accidentally miss a dose of a medicine. Discuss what to do for each medicine, because it may be different for each one. Write it down.
• Talk to your doctor before you start taking other medicines. Many medicines can keep blood pressure medicines from working right. This will raise your blood pressure. Medicines that could cause a problem include:
  • Reference Nonsteroidal anti-inflammatory drugs Opens New Window (NSAIDs), such as ibuprofen (for example, Advil or Motrin), indomethacin (Indocin), ketoprofen, naproxen (for example, Aleve or Naprosyn), and piroxicam (Feldene).
  • Decongestants, such as pseudoephedrine (for example, Sudafed).
  • Herbal or homeopathic remedies.
