Beta-blockers may not be as effective when taken alongside other medications. When you’re talking to a healthcare provider about beta-blockers, be open about any current medications or over-the-counter supplements you take. This can help you reduce the risk of issues.
Let your doctor know about all other medical conditions you have before you start on a beta-blocker. Also, tell your doctor about all medicines you’re taking, especially the following:
Never stop taking a beta-blocker abruptly without speaking to your healthcare provider.
Beta-Blockers, Alcohol, and Caffeine
Avoid eating or drinking products that contain alcohol, which can reduce the effects of beta-blockers. It’s also best to limit or avoid caffeine. This can also affect how beta-blockers work in your body.
Beta-Blockers and Pregnancy
Tell your doctor if you’re pregnant or might become pregnant while taking a beta-blocker.
Some beta-blockers may be safe to take during pregnancy, while others may be harmful.
In one study of pregnant women with structural heart disease, those taking beta-blockers had more infants who were small for gestational age (SGA) and a higher rate of congenital heart disease. But the researchers noted these women may also have been sicker, which can affect those outcomes on its own. Among the drugs, labetalol carried the lowest SGA risk and atenolol had the highest.
Discuss the risks and benefits of taking these drugs with your doctor. Also, talk to your healthcare provider before taking a beta-blocker if you’re breastfeeding.
Beta-Blockers and Certain Populations
Consult with your doctor if you have a slow heart rate (bradycardia), low blood pressure (hypotension), or Raynaud’s syndrome. Beta-blockers may not be recommended as first-line treatment when these conditions are present.
