Beta-blockers are one of the most widely prescribed classes of drugs to treat hypertension (high blood pressure) and are a mainstay treatment of congestive heart failure. Beta-blockers work by blocking the effects of epinephrine (adrenaline) and slowing the heart's rate, thereby decreasing the heart’s demand for oxygen. Long-term use of beta-blockers helps manage chronic heart failure.
Strokes can happen to anyone at any time, regardless of sex or age. Each year, nearly 800,000 people in the U.S. have a stroke, and 130,000 die from one. Of those who survive, more than two-thirds will have some disability. Recognizing stroke symptoms is key to preventing a needless death.

Beta-blockers can be taken in the morning, at meals, and at bedtime; taking them with food minimize side effects because absorption is slower. Follow the label directions on how often to take a beta-blocker. The number of doses you take each day, the time allowed between doses, and how long you need to take the medication will depend on your condition. Ask your doctor what to do if you miss a dose.
Beta-blockers should not be prescribed if you have low blood pressure or a slow pulse, because the further reduction in heart rate can cause dizziness and lightheadedness. If you have asthma or COPD, your doctor may not prescribe a beta-blocker because it may worsen symptoms. If you have heart failure and severe lung congestion, your doctor will treat your congestion before prescribing a beta-blocker.
While you are taking a beta-blocker, you may need to record your pulse every day. If your pulse is slower than it should be, contact your doctor about taking your beta-blocker that day.
Never stop taking a beta-blocker without speaking to your doctor first, even if you feel that it is not working. Sudden withdrawal can worsen angina and cause heart attacks.
