Are beta-blockers contraindicated in bradycardia?
Table of Contents
Patients who have either acute or chronic bradycardia and/or hypotension have relatively contraindication to beta-blocker usage.
What drugs are contraindicated with beta-blockers?

Some of the more common medicines that can interact with beta-blockers include:
- anti-arrhythmics – used to control irregular heartbeats.
- antihypertensives – used to lower blood pressure.
- antipsychotics – used to treat severe mental health problems.
- clonidine – used to treat high blood pressure and migraine.
Is metoprolol contraindicated in bradycardia?
Lopressor is contraindicated in sinus bradycardia, heart block greater than first degree, cardiogenic shock, and overt cardiac failure (see WARNINGS).
What are the two major contraindications of beta-blockers?
Who shouldn’t take beta-blockers?

- asthma, COPD, and other lung diseases.
- diabetes.
- low blood pressure (hypotension) or a slow heart rate (bradycardia)
- metabolic acidosis.
- serious blood circulation conditions, such as Raynaud’s phenomenon.
- severe congestive heart failure.
- severe peripheral artery disease.
Which beta-blocker is best for bradycardia?
Bisoprolol is preferred as it is more cardioselective than metoprolol and may cause more bradycardia.
What heart medications can cause bradycardia?
Cardiovascular medications that may trigger bradycardia include calcium channel blockers, beta-blockers, alpha/beta-adrenergic blockers, and digoxin.
- Calcium channel blockers.
- Beta-blockers.
- Alpha/beta-adrenergic blockers.
- Cardiac glycoside (digoxin)
- H 2 blockers.
- Lithium.
- Antidepressants.
- Neuromuscular blockers.
What do beta-blockers do to heart rate?
Beta blockers cause the heart to beat more slowly and with less force, which lowers blood pressure. Beta blockers also help widen veins and arteries to improve blood flow.
Can you take ivermectin with a beta-blocker?
Interactions between your drugs No interactions were found between ivermectin and Metoprolol Tartrate. However, this does not necessarily mean no interactions exist.
What heart rate is too low for metoprolol?
A heart rate of 55-60 is not unusual in people taking metoprolol. However, if a person had a heart rate that slow without a beta blocker, a doctor would be concerned that they would eventually develop symptoms from that slow of a heart rate.
Can metoprolol make heart rate too low?
Metoprolol Tartrate will likely cause a lowering of the heart rate. In some people, this can be too low, resulting in a condition known as bradycardia. Some experience fatigue as a side effect of taking beta-blockers.
Why are beta-blockers contraindicated in heart block?
The most frequent side effects of beta-blockers include: hypotension, bradycardia, bronchospasm, cold extremities, fatigue, headache, sleep disturbances and increased insulin resistance [1]. High-degree AV block is an absolute contraindication (if no pacemaker) [1].
How do beta-blockers lower heart rate?
Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause the heart to beat more slowly and with less force, which lowers blood pressure. Beta blockers also help widen veins and arteries to improve blood flow.
What are the contraindications for beta-blockers?
Specific beta-blockers are contraindicated depending on the patient’s past medical history. Patients diagnosed with long QT syndrome or who have had torsades de pointes in the past should not use the drug sotalol.
Can beta blockers cause severe sinus bradycardia?
You can develop severe sinus bradycardia in addition to bronchial asthma or chronic obstructive pulmonary disease. The contraindications of beta blockers can also cause severe sinus bradycardia. These sorts of issues are incredibly taxing and important to be alert for.
Should beta-blockers be used in patients with heart disease?
Practical recommendations for the use of beta-blockers in daily practice [1] Most evidence for the reduction of cardiovascular events by beta-blockers concerns acute coronary syndrome patients; especially in the presence of LV dysfunction. High-degree AV block (without a pacemaker) is an absolute contraindication.
Can beta blockers be used to treat congestive heart failure?
Congestive heart failure. Beta blockers are only indicated in cases of compensated, stable congestive heart failure; in cases of acute decompensated heart failure, beta blockers will cause a further decrease in ejection fraction, worsening the patient’s current symptoms.
