Propranolol is used for:
Treating high blood pressure or atrial fibrillation. It is used in patients with angina to decrease angina frequency and increase exercise tolerance. It is used to decrease the risk of heart death in certain patients who have survived a heart attack. It is used to manage certain types of tremors, a heart condition called hypertrophic subaortic stenosis, or certain symptoms of pheochromocytoma (an adrenal tumor). It is used to prevent migraine headaches. It may also be used for other conditions as determined by your doctor.
Propranolol is a beta-blocker. It works by slowing down the heart and decreasing the amount of blood it pumps out. This helps to decrease blood pressure, helps the heart pump more efficiently, and reduces the workload on the heart. Exactly how Propranolol works to treat migraines or tremors is not known.
Do NOT use Propranolol if:
- you are allergic to any ingredient in Propranolol
- you have moderate to severe heart block, uncontrolled heart failure, shock caused by serious heart problems, very slow heartbeat with heart block, or very low blood pressure after a heart attack
- you have asthma or Raynaud syndrome
- the patient is 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.
How to use Propranolol:
Use Propranolol as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take Propranolol by mouth. Talk with your doctor about how you should take it with regard to food.
- If you are taking an antacid with aluminum in it, take it at least 2 hours after you take Propranolol.
- Take Propranolol on a regular schedule to get the most benefit from it. Taking Propranolol at the same time each day will help you remember to take it.
- Continue to take Propranolol even if you feel well. Do not miss any doses.
- Do not suddenly stop taking Propranolol. You may have an increased risk of side effects. If you need to stop Propranolol or add a new medicine, your doctor will gradually lower your dose.
- If you miss a dose of Propranolol, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Propranolol.
