Summary

Beta blockers are prescription medications that reduce the workload of the heart and lower blood pressure. They are commonly prescribed to relieve angina (a certain type of chest pain, pressure or discomfort) or to treat heart failure. They are also prescribed for people who have high blood pressure (hypertension).

Patients who take beta blockers may experience side effects such as a very slow heart rate (bradycardia), dizziness or increased tiredness. Patients may also become more sensitive to cold.

Angina

There are a number of factors that can affect the use of beta blockers, including medical conditions and other drugs. Patients should provide their physician with a detailed medical history and current medications to determine if beta blockers are appropriate for them. In addition, patients are urged to not stop taking beta blockers abruptly, unless ordered to do so by their physicians. Otherwise, they could experience a rebound effect that increases their risk of angina and heart attack. Any unusual symptoms resulting from taking beta blockers should be reported to a physician.
