Doctors prescribe beta blockers to prevent, treat or improve symptoms in a variety of conditions, such as:
Beta blockers aren't usually prescribed for blood pressure until other medications, such as diuretics, haven't worked effectively. Your doctor may prescribe beta blockers as one of several medications to lower your blood pressure, including angiotensin-converting enzyme (ACE) inhibitors, diuretics or calcium channel blockers.
Beta blockers may not work as effectively for black and older people, especially when taken without other blood pressure medications.
Side effects may occur in people taking beta blockers. However, many people who take beta blockers won't have any side effects.
Common side effects of beta blockers include:
Less common side effects include:
Beta blockers generally aren't used in people with asthma because of concerns that the medication may trigger severe asthma attacks. In people who have diabetes, beta blockers may block signs of low blood sugar, such as rapid heartbeat. It's important to monitor your blood sugar regularly.
Beta blockers can also affect your cholesterol and triglyceride levels, causing a slight increase in triglycerides and a modest decrease in high-density lipoprotein, the "good" cholesterol. These changes often are temporary. You shouldn't abruptly stop taking a beta blocker because doing so could increase your risk of a heart attack or other heart problems.
