What is carvedilol?

  • Carvedilol has many uses. It is used to treat high blood pressure and heart failure. Carvedilol is also used after a heart attack, to improve the chance of survival if your heart is not pumping well.
  • Carvedilol works by blocking certain chemicals in the body, and in that way, slows the heart rate, lowers blood pressure and reduces any strain on the heart. It makes it easier for the heart to pump blood.


  • The dose of carvedilol will be different for different people. Your doctor will usually start you on a low dose and increase this over a few days. This allows your body to get used to the medicine and reduces unwanted side effects.
  • Always take your carvedilol exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much carvedilol to take, how often to take it, and any special instructions. 

How to take carvedilol

  • Take your carvedilol dose at the same time each day.
  • Swallow your tablets whole or halved, with a glass of water. Do not crush or chew them.
  • Take carvedilol with food, or immediately after food. It may cause stomach upset if you take it without food.
  • Limit drinking alcohol while you are taking carvedilol.
  • If you forget to take your tablet, take is as soon as your remember that day.
  • But, if it is nearly time for your next tablet, just take the next tablet at the right time. Do not take double the amount of tablets.
  • Do not stop taking carvedilol suddenly; speak to your doctor or nurse before stopping.

Possible side effects

Like all medicines, carvedilol can cause unwanted side effects, although not everyone gets them. Often unwanted side effects improve as your body gets used to the new medicine.
