Inderal 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. Inderal 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 Inderal works to treat migraines or tremors is not known.
