Taking a Beta-Blocker

A beta-blocker decreases your heart’s workload and helps it beat more regularly. It can also help increase your heart's pumping ability. This can reduce chest pain. It may also lower your blood pressure. This medicine is sometimes used to treat other medical problems such as high blood pressure and irregular heart rhythms.

Medicine tips

  • Read the fact sheet that comes with your medicine. Ask for a sheet if you don’t get one.

  • Take your beta-blocker exactly as directed. Follow the directions on the label.

  • Take your medicine at the same time or times every day.

  • If you take a long-acting tablet or capsule, swallow it whole. Don't chew it, crush it, or break it open unless you are told it's OK to do so.

  • If you miss a dose, take it as soon as you remember — unless it’s almost time for your next dose. If so, skip the missed dose. Don't take a double dose.

For your safety

  • Tell any healthcare provider you have (including your pharmacist) before taking any other prescription or over-the-counter medicines. This includes vitamin supplements and herbal remedies.

  • Don't stop taking your beta-blocker unless your healthcare provider tells you to. Doing so can make your condition worse. When it is time to stop, follow your healthcare provider’s instructions.

  • Don't drive or operate heavy machinery unless you are sure your beta-blocker doesn’t make you sleepy or dizzy.

  • To prevent dizziness, get up slowly after sitting or lying down.

  • Ask your healthcare provider to check your pulse rate before and after taking your beta-blocker.
