(proe pran' oh lole)
Do not stop taking propranolol without talking to your doctor first. If propranolol is stopped suddenly, it may cause chest pain or heart attack in some people.
WHY is this medicine prescribed?
Propranolol is used to treat high blood pressure, abnormal heart rhythms, heart disease, pheochromocytoma (tumor on a small gland near the kidneys), and certain types of tremor. It is also used to prevent angina (chest pain) and migraine headaches. Propranolol is also used 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.
HOW should this medicine be used?
Propranolol comes as a tablet or capsule to take by mouth. It also comes as a solution or concentrate. The extended-release (long-acting) product usually is taken once a day. Immediate-acting propranolol may be taken two, three, or four times a day. Take propranolol at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take propranolol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Do not cut, crush, or chew extended-release tablets; swallow them whole. Dilute the concentrated oral liquid with water, juice, or soft drinks, or mix it with applesauce or pudding just before taking it.
