Can You Take Beta Blockers And Exercise
High blood pressure is known as the silent killer. According to the U.S. Centers for Disease Control and Prevention , nearly half of adults in the U.S. have the condition. Still, many arent aware of it because there are no apparent symptoms until a heart attack or stroke happens.
Beta blockers, also called beta-adrenergic blocking agents, are widely-prescribed medications to decrease high blood pressure and prevent heart disease. While exercise can lower your blood pressure, overexertion can be dangerous. This guide will help people with hypertension learn how to safely mix beta blockers and exercise.

Dosage Forms Of Metoprolol
There are two different types of metoprolol: metoprolol tartrate and metoprolol succinate. Metoprolol tartrate is used in immediate-release tablets and comes in 25 mg, 37.5 mg, 50 mg, 75 mg, and 100 mg pills. Metoprolol succinate is used in the extended-release capsules and tablets and comes in 25 mg, 50 mg, 100 mg, and 200 mg pills. The specific dose recommended by your healthcare provider will vary depending on the condition being treated, as well as your other medical issues.
How Do Beta Blocker Drugs Affect Exercise
Beta blockers are a type of cardiac medication prescribed after a heart attack or to treat abnormal heart rhythms and other conditions. They slow down your heartbeat, and that raises a common question about them: Do they affect your ability to exercise?
The answer can vary a great deal, depending on the severity of your condition, so checking with your healthcare provider is vital. Its also important to understand how these drugs affect your heart.

What If I Forget To Take It
If you forget to take a dose of your beta blocker, take it as soon as you remember, unless it is nearly time for your next dose. In this case, just leave out the missed dose and take your next dose as normal.
Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.
If you often forget doses, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
How Exercise Reduces Your Resting Heart Rate
When you do aerobic exercise, blood flow is directed toward the muscles you’re using and away from areas that aren’t doing much . There is increased blood flow as well as an increase in the volume of blood returning to the heart. Over time, the left ventricle adapts and enlarges to accommodate the increased volume. This larger cavity can hold more blood, and ejects more blood per beat, even at rest your resting heart rate drops because each beat delivers a bigger burst of blood, and fewer beats are needed.

Visual And Breathing Problems
When you take metoprolol, you also may experience a problem focusing your vision. Objects near or far–or both–may be blurry, and you may not be able to bring them into focus. Another potential common side effect of the drug is feeling short of breath: you cannot seem to get enough air into your lungs to be comfortable.

Who Can Take Beta Blockers
Beta blockers are not suitable for everyone. To make sure they are safe for you, tell your doctor before starting a beta blocker if you have:
- had an allergic reaction to a beta blocker or any other medicine in the past
- low blood pressure or a slow heart rate
- serious blood circulation problems in your limbs
- metabolic acidosis when there’s too much acid in your blood
- lung disease or asthma
Tell your doctor if you’re trying to get pregnant, are already pregnant or breastfeeding.
It’s important not to stop taking beta blockers without seeking your doctor’s advice. In some cases suddenly stopping the medicine may make your health condition worse.

Which Beta Blockers Can Be Used For Heart Failure
Beta blockers are often given to patients experiencing a heart attack with the goal being to prevent a second heart attack from happening.
The American College of Cardiology specifically recommends the following beta blockers, which are FDA approved for heart failure:
- Coreg
- Toprol XL
- Zebeta
It is important to note that only the extended-release version ofmetoprolol is approved by the FDA for heart failure, notmetoprolol tartrate.
When using these beta blockers for heart failure treatment, they prevent the heart from being overstimulated and pumping too often, explainsJason Reed, Pharm.D.
Most beta blockers also decrease how hard the heart muscle pumps, Dr. Reed explains. But these beta blockers do not do that, which is why they are able to treat the disease without making symptoms worse.
Interms of differencesbetween the beta blockers used for heart failure, he says, carvedilol blocks beta-1 beta-2 receptors in the heart, as well as alpha-1 receptors in the blood vessels. Metoprolol and bisoprolol primarily block beta-1 receptors in the heart. Although these beta blockers have some differences, they are effective at protecting the heart and reducing the risk of problems from heart failure.

Concerns About Exercising While On Beta Blockers
Its important to remember that your heart rate is being slowed, and to adjust accordingly if before you took these drugs you monitored your exercise using heart rate, said Dr. Fletcher, who is also a volunteer with the American Heart Association.
Dont overdo it trying to get your heart rate up to previous levels, he said.
There are a couple of ways to monitor your exercise intensity.
Exercise hard to the point of being tired but not excessively hard, Dr. Fletcher said. If you reach a point where it is hard to talk, that is probably too much.
A Bunch Of Beta Blockers
You can tell a beta blocker by its generic name they all end in lol. Each has its own particular way of blocking beta receptors. This accounts for their different actions and side effects.
More than a dozen beta blockers have been approved for use in the United States . They fall into three main groups.
Nonselective. The earliest beta blockers, like propranolol, affect both beta-1 and beta-2 receptors. Nonselective beta blockers should be used with caution, if at all, in smokers or people with asthma or other lung conditions.
Cardioselective. A number of beta blockers, including atenolol and metoprolol , were designed to block only beta-1 receptors in heart cells. Since they dont affect beta-2 receptors in blood vessels and the lungs, cardioselective beta blockers are safer for people with lung disorders.
Third-generation. Some beta blockers do more than block beta receptors. Labetalol blocks alpha receptors, too. This further helps relax blood vessels. Nebivolol stimulates the inner lining of blood vessels to generate nitric oxide, which helps the vessels relax. Carvedilol does both.

Calcium channel blockers can be used during pregnancy to manage high blood pressure and preeclampsia. However, you should always consult with your doctor before taking calcium channel blockers during pregnancy.
These drugs may pass into breast milk, but no adverse effect on breastfed infants has been found. Discuss the risks and benefits of using calcium channel blockers while breastfeeding with your doctor.
The safety of calcium channel blockers in children has not been established however, no problems have been found to date. Discuss the risks and benefits of giving your child calcium channel blockers with your childs doctor.
Older adults have more side effects from calcium channel blockers than younger people. Doctors usually prescribe lower doses.
The No 1 Reason People Stop Taking Beta
The top reason patients stop using beta-blockers is admission to the hospital for various conditions, not just heart failure, Dr. Tang says. However, most people should not stop, even if they are hospitalized, unless the doctors decided that it is more harm than good.
Research shows that patients fare better when they continue taking beta-blockers while in the hospital, even with acute heart failure.
An inability to tolerate beta-blockers indicates a worsening heart condition, says Dr. Tang. Other testing may be necessary to determine if the heart is too weak for beta-blockers.
This may even apply for patients whose heart function has recovered to the normal range. Recent clinical studies have shown that, even in those with full recovery of their heart structure and function, stopping drugs like beta-blockers can reverse the recovery course and can be detrimental, he adds.

Is It Safe To Stop Using Beta
Its dangerous to stop taking beta-blockers suddenly, even if youre experiencing side effects.
When you take beta-blockers, your body gets used to your hearts slower speed. If you stop taking them suddenly, you could increase your risk of a serious heart problem, such as a heart attack.
Contact your doctor if you experience unpleasant side effects with beta-blockers that last for more than a day or two. Your doctor might suggest another type of medication, but youll still need to slowly taper your beta-blocker dose.

How Beta Blockers Affect Your Target Heart Rate
If you have high blood pressure, treatment often requires medication with a beta blocker, a common type of blood pressure medication that lowers your resting heart rate. Exercising regularly, another important component of managing high blood pressure, also lowers your resting heart rate. Hence, if you take a beta blocker, you will need to make some adjustments when calculating your target heart rate while doing aerobic exercise.
Beta Blockers And Physical Activity
Interestingly, beta blockers and exercise have some similar effects on the body.
Your blood pressure and heart rate are similarly changed by exercise and beta blockers, said Gerald Fletcher, M.D., Professor of Medicine at the Mayo Clinic in Jacksonville, Florida. When you become exercise-trained your heart slows and your blood pressure lowers.
Of course, that doesnt mean you can take beta blockers in lieu of exercise. Exercise has many other benefits and is important to maintain your health. Read how physical activity improves the quality of life.

Thank you both for your quick replies. This will sound silly but the doctor gave me propranolol for anxiety and at the start I did feel very chilled. I felt so relaxed that I felt like I was hardly breathing, if that makes sense. That’s when I decided to check my pulse and it was very low. This was only after a few days on just 10mgs. So now I feel more anxious because of the low heart rate!
Posted 5 years ago
Yes, I’ve heard of heart rates that low. What was your blood pressure before you started taking it and what is it now?
Posted 5 years ago
I couldn’t tell you. All I know is that my gp says ” that’s normal” I should pay more attention really. Anyway I have been in so much pain which is stressing me out that I decided to cut the 10mg in half and have been taking it in the morning and then in the evening if I need it. Even on 5mg my heart rate was 48 but it is doing the trick of keeping me calm at the moment
Posted 5 years ago
Oh mine has never went that low the lowest mine has ever been is 58 but since that night I have worried ever since

Thx for advice day I took 10mg 2 hours ago and my pulse is 64 I need to stop worrying lol

How Do Beta Blockers Work
Beta blockers work by limiting the effects of epinephrine a stress hormone. This slows your heartbeat, decreases blood pressure, and opens blood vessels to improve blood flow. These medications can treat high blood pressure , irregular heart rhythms , chest pains, heartfailure, migraines, and heart attacks.
For patients with heart failure, beta blockers typically work by reducing a patients heart rate, explains Dawn Shill, Pharm.D., a pharmacist for the Veterans Affairs Healthcare System in Anchorage, Alaska.
Beta blockers help to improve the balance of myocardial supply and demand. Dr. Shill says, Basically, sometimes heart failure is ischemic. Meaning, there is weakened muscular tissue in the heart that leads to a decreased amount of blood pumped from the heart. Beta blockers can help improve function in certain areas of the heart by reducing the amount of oxygen supply needed for the heart to function at an optimal level.
Research also shows that beta blockers reduce the release of norepinephrine. Along with epinephrine, norepinephrine normally binds to receptors throughout the body and is involved with blood pressure and heart rate. Blocking the binding of these neurotransmitters to their receptors helps reduce heart rate and blood pressure.
