Do Other Drugs Interact With Beta-Blockers?

A beta-blocker is often prescribed with a diuretic (''water pill''), or other medications such as ACE inhibitors and angiotensin receptor blockers (ARBs), which lower blood pressure and improve heart failure symptoms. If you have side effects after taking your heart drugs together, contact your health care provider. You may need to change the times you take each medication.

It is important that your doctor is aware of all the drugs you are taking -- including over-the-counter drugs, herbs and supplements -- because they have the potential to interact with beta-blockers.

Can Pregnant Women Take Beta-Blockers?

Use of beta-blockers during pregnancy may affect the growing fetus by slowing its heart rate, and lowering its blood sugar level and blood pressure. Beta-blockers can also pass to the infant through breast milk, causing low blood pressure, difficulty breathing and a slowed heart rate.

Women should inform their doctor if they are trying to get pregnant or become pregnant while on beta-blockers or are breastfeeding.


Can Children Take Beta-Blockers?

Certain beta-blockers have been used successfully in children to treat a variety of conditions, including heart failure, irregular heartbeat, high blood pressure, and migraines.

Can Older Adults Take Beta-Blockers?

Beta-blockers, usually in lower doses, are frequently prescribed to older people.
