Beta-Blockers for High Blood Pressure

Check your pulse. Your doctor may ask you to take your pulse regularly to make sure your heart rate is not too slow. To learn how to take your pulse, see the topic Reference Taking a Pulse (Heart Rate) Opens New Window Reference Opens New Window.

Diabetes. If you have diabetes, beta-blockers may cause higher blood sugar levels. Watch closely for symptoms of low blood sugar, because beta-blockers can hide your symptoms.

Grapefruit juice. Grapefruit juice may affect how beta-blockers work. Ask your doctor if you need to make any changes to avoid problems. For more information, see Reference Grapefruit Juice and Medicine.

Cold weather. Beta-blockers may make you more sensitive to cold weather. Dress warmly and if needed, limit your time in cold weather.

Sun exposure. Beta-blockers may make you more sensitive to sunlight. You might get sunburnt easily or get a rash. To prevent problems, try wearing sun block, long sleeved shirts, and hats.

Allergic reactions. If you have food, medicine, or insect-sting allergies, beta-blockers may cause allergic reactions to be worse and harder to treat. If you have a severe allergic reaction, tell your doctor that you are taking a beta-blocker.

Reference Reference High Blood Pressure: Taking Medicines Properly.

Taking medicine

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.

There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Reference Taking Medicines as Prescribed.

Advice for women

If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.

Checkups

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
