If you have angina or have had heart problems, DO NOT suddenly stop taking propranolol concentrate without first consulting with your doctor. Severe chest pain, heart attack, very fast heart rate, and irregular heart rhythm may occur. If your doctor decides you should no longer take propranolol concentrate, the dosage should be gradually reduced according to your doctor's instructions. You should be closely watched by your doctor and limit physical activity to a minimum, particularly if you have certain kinds of heart disease. Some medicines or medical conditions may interact with propranolol concentrate.
Propranolol concentrate is used for:
Treating high blood pressure; prevention of angina pectoris (chest pain); management of a heart condition called hypertrophic subaortic stenosis; treating and preventing certain abnormal or rapid heart rhythms; improvement of survival after a heart attack in certain patients; treatment of tremor; prevention of migraine headaches; and treating symptoms of adrenal gland tumors. It may be used alone or with other medicines. It may also be used for other conditions as determined by your doctor.
Propranolol concentrate is a beta-adrenergic blocking agent. It works by slowing down the heart and reducing blood pressure, which helps it pump more efficiently and reduces the workload on the heart. It may also interfere with the action of adrenalin and other similar chemicals in the brain preventing migraine headaches.
Do NOT use propranolol concentrate if:
- you are allergic to any ingredient in propranolol concentrate
- you have a very slow heartbeat and heart block; had a heart attack and have very low blood pressure or uncontrolled heart failure or shock caused by heart failure
- you have asthma or Raynaud phenomenon
- you are a child with diabetes or heart failure
- you are taking mibefradil
Contact your doctor or health care provider right away if any of these apply to you.
