Uses for beta blockers

Doctors prescribe beta blockers to prevent, treat or improve symptoms in a variety of conditions, such as:

• High blood pressure
• Irregular heart rhythm (arrhythmia)
• Heart failure
• Chest pain (angina)
• Heart attacks
• Migraine
• Certain types of tremors

Beta blockers aren't usually prescribed for blood pressure until other medications, such as diuretics, haven't worked effectively. Your doctor may prescribe beta blockers as one of several medications to lower your blood pressure, including angiotensin-converting enzyme (ACE) inhibitors, diuretics or calcium channel blockers.

Beta blockers may not work as effectively for people of African heritage and older people, especially when taken without other blood pressure medications.
