What are Beta Blockers?

Beta blockers are drugs used to treat heart conditions, hypertension, glaucoma, migraine and psychiatric disorders, such as performance anxieties. Some commonly used beta blockers are nadolol, metoprolol and atenolol.


Beta blockers affect the central nervous system, controlling mental alertness, lung function, heart rate and blood vessels. The most important function is that it slows the heart rate to a normal rate and rhythm.


The dosage is based on the condition being treated. For example, 10 to 40 mg for performance anxiety, 20 to 60 mg for lithium-induced tremors, and 10 to 30 mg for the treatment of akathisia.


Individuals with blood pressure levels 90/60 mmHg and below, or a resting heartbeat of 55 per minute, should not use beta blockers, because it decreases the heart rate. Beta blockers can also cause a skin rash.


A rash is rarely fatal, but medication that causes a rash should be discontinued. Individuals who are allergic to drugs containing sulfa should refrain from using of these drugs.


Treatment includes discontinuing the use of the medication and consulting the prescribing physician for a replacement. A topical itch or non-itch cream can be used to remove or relieve the symptoms of a rash.
