What are Beta Blockers?

A class of medications that block beta-adrenergic substances including adrenaline, which is a key element in the autonomic nervous system’s sympathetic features and heart muscle activation.

Also, older individuals, especially those older than 60, are more likely to suffer unwanted side effects from the drugs.

Talking Your Treatment Over With Your Physician

If you have been prescribed a beta blocker to treat a condition, you should talk about the medication benefits and side effects over with your healthcare provider. If you notice worsening side effects, or side effects that make your daily life difficult or disrupt your daily activities, you should let your healthcare provider know because your medication might need to be adjusted or changed.

In general, beta-blockers are very effective drugs and are one of the more commonly prescribed medications today.  Because it can treat multiple disorders, it might be effective in addressing multiple health issues and symptoms that you are facing. If you are taking a beta blocker that causes serious side effects and disrupts your life, your provider can prescribe a different one, which you might be able to tolerate much better.
