Why has my veterinarian prescribed this medicine?

Propranolol is a non-selective beta blocking agent, which is used to correct irregular heartbeat. Propranolol decreases the heart's need for blood and oxygen and therefore reduces the amount of work the heart must do. Propranolol may also be used to decrease high blood pressure. This medication may be prescribed for other conditions as determined by your veterinarian.
