Beta blockers are also known as beta-adrenergic blocking agents. They treat a variety of conditions including hypertension (high blood pressure), glaucoma, and migraines. Beta blockers work by blocking the effects of epinephrine, the hormone that produces adrenaline. The beta blockers will reduce heart beats with less force, thus reducing blood pressure. They also help to open up blood vessels to improve blood flow.

Examples of beta blockers include:

• Acebutolol
• Atenolol
• Bisoprolol
• Carvedilol
• Metoprolol
• Nadolol
• Nebivolol
• Propranolol

Beta blockers are used to treat and improve symptoms of high blood pressure, irregular heart rhythm, heart failure, chest pain, heart attacks, hyperthyroidism, and much more. Beta blockers aren’t prescribed until other medications haven’t work effectively.

Side effects may occur in taking beta blockers, including fatigue, cold hands, dizziness, and weakness. Beta blockers aren’t used in people with asthma, and requires monitoring for people with diabetes.

This medication can also affect your cholesterol and triglycerides levels, but these changes are only temporary and won’t last.
