Beta-Blocking Drugs

When are beta-blocking drugs used?

Beta-blocking drugs, also called beta blockers, treat the symptoms of hyperthyroidism. They do not significantly affect the gland or the levels of thyroid hormones in the blood. Instead, they “block” the effects of thyroid hormones.

Beta blockers are most useful for patients whose hyperthyroidism makes them uncomfortable. High hormone levels can cause a faster heart rate and trembling. Beta-blocking drugs help control these symptoms.

Beta-blocking drugs should not be used by patients with asthma.
