Propranolol is used to treat high blood pressure, irregular heart rhythms, pheochromocytoma (tumor on a small gland near the kidneys), certain types of tremor, and hypertrophic subaortic stenosis (a heart muscle disease). It is also used to prevent angina (chest pain), migraine headaches, and to improve survival after a heart attack. Propranolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure. High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. Beta blockers can be helpful in the treatment of the physical symptoms of anxiety, especially social anxiety. Physicians prescribe them to control rapid heartbeat, shaking, trembling, and blushing in anxious situations for several hours. Often social anxiety symptoms are so strong that beta blockers, while helpful, cannot reduce enough of the symptoms to provide relief. Because they can lower blood pressure and slow heart rate, people diagnosed with low blood pressure or heart conditions may not be able to take them. May reduce some peripheral symptoms of anxiety, such as tachycardia and sweating, and general tension, can help control symptoms of stage fright and public-speaking fears, has few side effects. Taken occasionally, propranolol has almost no side effects. Atenolol is longer acting than propranolol and generally has fewer side effects. If taken daily, abrupt withdrawal can cause very high blood pressure. If there is no response, increase to two 50 mg tablets, taken together or divided. Not recommended for patients with asthma or any other respiratory illness that causes wheezing, or for patients with diabetes. Some people may feel a little light-headed, sleepy, short-term memory loss, unusually slow pulse, lethargy, insomnia, diarrhea, cold hands and feet, numbness and/or tingling of fingers and toes. It has less of a tendency to produce wheezing than other beta blockers. Use alcohol with caution, since alcohol can increase the sedative effect and exaggerate this drug's ability to lower blood pressure. After two weeks of 100 mg the patient should notice a marked decrease in the racing heart, trembling, blushing, and/or sweating in social situations.
Dangerous reactions (shock, cardiac infarction) may be rare but they are possible in subjects with pre-existing heart disease or when propranolol is withdrawn suddenly.
