Carvedilol® belongs to a group of medicines called beta-blockers that work by relaxing and widening the blood vessels. This makes it easier for your heart to pump blood around the body and reduces blood pressure and strain on your heart.
Carvedilol is used:
- for the treatment of high blood pressure (hypertension),
- for the treatment of chest pain that occurs when the arteries that supply your heart with blood carrying oxygen are narrowed, which results in less oxygen reaching your heart muscles (angina),
- for the treatment of weakening of the heart muscle (heart failure), in combination with other medicines.
Before use this drug, ask your doctor:
Do not take Carvedilol:
- if you are allergic to carvedilol or any of the other ingredients of this medicine.
- if you have a history of wheezing due to asthma or other lung diseases.
- if you have been told you have very severe heart failure and you have fluid retention (swelling) which is being treated with injections of medicines into your veins (intravenously).
- if you have liver disease.
- if you have been told that you have a very slow heartbeat.
- if you have very low blood pressure.
- if you have been told you have a condition called Prinzmetal’s angina.
- if you have phaeochromocytoma (a tumour of the adrenal gland causing high blood pressure) which is not being treated.
- if you are suffering from serious disturbances in the body’s acid-base balance (metabolic acidosis).
- if you have very poor blood circulation in the hands and feet resulting in coldness and pain in them.
- if you have a particular conduction defect of the heart (called an AV heart block Grade II or III (unless a pacemaker is fitted) or a SA block).
- if you are currently being treated with injections of verapamil or diltiazem (used in the treatment of high blood pressure or heart problems).
If any of these apply to you, do not take Carvedilol.
