When beta blockers are used

Beta blockers are not recommended as a first treatment if you have only high blood pressure. Beta blockers are not usually used for high blood pressure unless other medicines, such as diuretics, have not worked well. A beta blocker may be one of several medicines used to lower blood pressure.

Beta blockers are used to prevent, treat, or improve symptoms in other conditions, such as:

• Irregular heartbeats, called arrhythmias.
• Heart failure.
• Chest pain, called angina.
• Heart attacks.
• Migraine.
• Some types of tremors.
