Beta-blocker medicines slow the heart rate and decrease how forcefully the heart contracts, reducing the amount of oxygen the heart needs to work. Beta-blockers are often used to treat heart conditions, including high blood pressure, heart failure, and fast or irregular heart rates.
Beta-blockers are also used for other health problems such as migraine headaches and glaucoma.
