Do you have to take beta blockers for life?

Guidelines recommend beta blocker therapy for three years, but that may not be necessary. Beta blockers work by blocking the effects of the hormone epinephrine, also called adrenaline. In the past, many people have taken beta blockers for years — often indefinitely — after a heart attack.

What is a normal heart rate on beta blockers?

If you are 70 years old, for instance, your adjusted target heart rate would be (220 - 70) 0.8 = 120 beats per minute. For people on a beta blocker, one suggestion is to adjust your target heart rate by the same amount that the beta blocker has reduced your resting heart rate (usually around 10 beats per minute).

When should you not take beta blockers?

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 chronic obstructive pulmonary disease (COPD), your doctor may not prescribe a beta-blocker because it may worsen symptoms.

Why are beta blockers bad?

Overexposure to these hormones can be harmful. Too much adrenaline can lead to rapid heartbeat, high blood pressure, excessive sweating, anxiety, and palpitations. Blocking the release of these hormones blockers decreases the oxygen demands and reduces stress on the heart.

Are beta blockers bad for you long term?

Beta-blockers can have helpful, or harmful, effect on heart. Unfortunately, the researchers found, this growth also predisposes the heart to eventual failure. Traditionally, beta-blockers targeting the beta-adrenergic receptors have been utilized as a long-term therapy for heart failure.

How do I get off beta blockers?

Any change of dose should be made slowly as your doctor recommends. It is important not to stop beta blockers suddenly or run out of medication. Don't stop taking a beta blocker suddenly without first consulting a doctor. When you take a beta blocker regularly, the body becomes used to it.

However, if you have problems with beta blockers, there are alternative drugs available. If you have angina or AF, for example, other drugs that slow the heart rate, such as diltiazem or verapamil, may be substituted.

Can beta blockers damage your heart?

When taken in very high doses, beta blockers can worsen heart failure, slow the heart rate too much, and produce wheezing and a worsening of lung disease. High doses may also cause lightheadedness from a drop in blood pressure, which puts people at risk for falls and injury.

Patric Henckens


What is the safest beta blocker?

A number of beta blockers, including atenolol (Tenormin) and metoprolol (Toprol, Lopressor), were designed to block only beta-1 receptors in heart cells. Since they don't affect beta-2 receptors in blood vessels and the lungs, cardioselective beta blockers are safer for people with lung disorders.

Is aspirin a beta blocker?

Aspirin blunts the vasodilation caused by both angiotensin-converting enzyme (ACE) inhibitors and beta-blockers in hypertensive patients and in patients with heart failure. Aspirin did not significantly affect the heart rate or systolic blood pressure response in either the placebo or carvedilol groups.

Why do beta blockers cause depression?

Also, because most patients in this study received propranolol, the authors were unable to confirm a long-held belief that highly lipophilic beta blockers (such as propranolol, metoprolol, and timolol) are more likely than hydrophilic beta blockers such as atenolol to produce depression.

Are beta blockers addictive?

Beta blockers are capable of blocking neurotransmitters such as norepinephrine and epinephrine (adrenaline) from attaching to beta receptors on nerves. Beta blockers are non-addictive, non-narcotic sedatives that help reduce symptoms of anxiety.



Can you lose weight on beta blockers?

What happens if you take blood pressure medicine and don't need it?

Medication to control high blood pressure only works if you take it. If you stop taking antihypertensive medication without discussing it with your doctor, you put yourself at risk for a stroke. The higher the blood pressure, the higher the risk for stroke and other health consequences.
