Nearly half of all U.S. adults have <\/span>high blood pressure<\/span><\/a> or hypertension. High blood pressure also puts you at risk for heart failure, which is the leading cause of death in the U.S. according to the <\/span>Centers for Disease Control and Prevention<\/span> (CDC). Beta blockers are commonly prescribed to lower blood pressure and reduce the risk of heart disease. <\/span>Coreg<\/span><\/a> and its generic version, <\/span>carvedilol<\/span><\/a>, are considered a first line of defense for people who have had congestive heart failure. Beta blockers work to block hormones like epinephrine (adrenaline), which stimulate your heart and increase your heart rate.<\/span><\/p>\n

Carvedilol not only reduces blood pressure but also helps to prevent heart attacks. Although carvedilol is well-tolerated and effective, like most medications, there are some important considerations you and your healthcare provider should discuss before taking it. Here, we discuss what you should avoid when taking the beta blocker.<\/span><\/p>\n

How carvedilol works<\/span><\/h2>\n

Carvedilol<\/span><\/a> works in two ways to treat high blood pressure and prevent heart failure. Primarily, \u201c<\/span>carvedilol reduces the effects of hormones like adrenaline on the heart,\u201d says <\/span>Jacob Hascalovici<\/span><\/a>, MD, chief medical officer of <\/span>Bliss Healthcare<\/span><\/a>. \u201cThis helps to slow down the heart rate and decrease the force with which the heart contracts.\u201d Specifically, he says, \u201cIt works by blocking certain receptors in the body known as beta receptors. These receptors are found in various tissues, including the heart.\u201d\u00a0<\/span><\/p>\n

While carvedilol\u2019s main action is as a beta-blocker, it also works as an alpha-blocker.\u00a0<\/span><\/p>\n

\u201cAlpha receptors are found in blood vessels, and their activation can cause those blood vessels to narrow, resulting in increased blood pressure,\u201d Dr. Hascalovici says. By blocking these alpha receptors, he says, \u201ccarvedilol helps to relax and widen the blood vessels, promoting easier blood flow and reducing blood pressure.\u201d\u00a0<\/span><\/p>\n

Because of its dual activities, carvedilol is one of the primary medications used to <\/span>prevent heart problems<\/span><\/a> and has been shown to decrease the likelihood of dying from a heart attack because it treats left ventricular dysfunction.\u00a0<\/span><\/p>\n\t\t

4 foods and beverages to avoid with carvedilol<\/span><\/h2>\n

\u201cWe usually recommend taking carvedilol with a meal, as food can help your body better absorb the medication,\u201d says <\/span>Kelvin Fernandez<\/span><\/a>, MD, founder of <\/span>Ace Med Boards<\/span><\/a> and a resident physician at Newark Beth Israel Hospital in New Jersey. The medication can lose efficacy, however, when paired with certain foods and drinks.\u00a0<\/span><\/p>\n

The following foods and drinks may reduce carvedilol\u2019s ability to work effectively or increase the risk of side effects.<\/span><\/p>\n

1. Grapefruit<\/span><\/h3>\n

Grapefruit often causes drug interactions, making the medication less effective or more likely to cause side effects\u2014not just carvedilol.\u00a0<\/span><\/p>\n

\u201c<\/span>Grapefruit and its juice may interact with carvedilol and affect its metabolism in the body,\u201d Dr. Hascalovici says. However, if you cannot start your day without a grapefruit or glass of grapefruit juice, Dr. Fernandez recommends speaking with a healthcare professional for an individualized treatment plan. <\/span>Finding the balance between what your lifestyle allows and what\u2019s best for your health is important.<\/span><\/p>\n

2. Bananas<\/span><\/h3>\n

Because potassium-rich foods like bananas have been shown to <\/span>potentially interact with carvedilol<\/span><\/a>, you may want to eat them only in moderation. For instance, if you put multiple bananas in your morning smoothie, your carvedilol may increase your risk of hyperkalemia, an elevated level of potassium in the bloodstream. This can be more of a problem for patients with kidney problems or taking other medications that increase potassium levels. Therefore, discuss your intake of bananas and your potassium levels with your healthcare provider before beginning to take carvedilol.\u00a0<\/span><\/p>\n

3. Alcohol<\/span><\/h3>\n

\u201c<\/span>It is generally recommended to limit or avoid alcohol consumption while taking carvedilol,\u201d Dr. Hascalovici says. Alcohol raises blood pressure, so drinking while taking carvedilol can be dangerous\u2014this is especially true if you\u2019ve just started taking the medication and are not sure how you react to it or how your blood pressure responds. You may feel dizzy or lightheaded when combining carvedilol and alcohol. If that\u2019s the case, stop consuming alcohol and speak with your healthcare provider.<\/span> \u00a0 <\/span>\u00a0<\/span><\/p>\n

4. Caffeine\u00a0<\/span><\/h3>\n

Many people report feeling jittery after consuming caffeinated beverages when taking carvedilol. Too much <\/span>caffeine<\/span><\/a>, like the other items on this list, can reduce the efficacy of the prescription drug.\u00a0<\/span><\/p>\n
