They are also in a larger class of drugs called 'Antiarrhythmatic' or 'Antiarrhythmic' drugs that are supposed to prevent irregular heart rhythms. They are given to people with high blood pressure, heart rhythm problems called 'Ventricular Tachycardia' and Atrial Fibrillation, as well as being the 'Standard of Care' for all cases of Heart Failure- meaning that doctors are obligated to put heart failure patients on beta blockers unless there is a medically justifiable reason not to.
Well, with the side effects of beta blockers that will be listed below, these seem like they just might be medically justifiable reasons not to give beta blockers, unfortunately the medical profession doesn't see it that way.
Beta Blocker Side Effects
"…side effects associated with beta-blockers include
congestive heart failure (CHF), reduced cardiac output,
fatigue, heart block, dizziness, depression,
bradycardia (decreased heart beat and function), cold extremities,
parathesia (a feeling of “pins and needles”), dyspnea
(shortness of breath), drowsiness, lethargy, insomnia,
headaches, poor memory, nausea, diarrhea, constipation,
colitis, wheezing, bronchospasm, Raynaud’s Syndrome
(burning, tingling, pain, numbness, or poor circulation in the hands and feet), claudication, hyperkalemia
(muscle cramps), muscle fatigue, lowered libido, impotence,
postural hypotension, raised triglycerides,
lowered HDL, raised LDL, and hyperglycemia."

Dangerous Conduction Problems
While beta blockers seems as though they should be life SAVING medications, this is not necessarily true and may even be more deadly, in certain people, than receiving no drug at all! Beta blockers can lead to a condition called Prolonged QT Interval which can lead to a deadly heart rhythm called 'Torsades de Pointes' which can occur in between 2.5 to 4% of all people that receive beta blocking medications.
Torsades de Pointes is a very specific heart rhythm that means your heart is not beating. Unfortunately, it LOOKS almost exactly the same on an EKG as a heart rhythm that requires emergency defibrillation. But Torsades doesn't respond to defribrillation, which makes it extremely deadly. While Beta Blockers help with minor abnormal heart rhythms, they actually CAUSE more deadly ones which can contribute to the extremely high rates of Congestive Heart Failure Death! Nice, huh!
While most people would not think of diabetes as a 'side effect' of a drug, unfortunately beta blockers side effects DO include the development of diabetes at such high rates that one study evaluating this had to stop the study before it was completed due to the high rates of diabetes in those who were taking the beta blockers!(3)
"Physicians should think carefully before using the
beta-blocker based strategy to treat hypertension"

Reduces the Risk of New-Onset Diabetes in Hypertensive Patients…
Unfortunately, this advice to 'think carefully' before giving beta blockers does not apply to those with congestive heart failure who are still under the standard of care to receive beta blockers on a routine basis. This is especially problematic because most people with CHF are elderly and already frail with multiple medical conditions. Having to also deal with new onset diabetes is not one of the beta blocker side effects that they should have to be subjected to.
Depletes Things That You Need
If a higher rate of Congestive Heart Failure Death from arrhythmias and diabetes weren't enough, other beta blocker side effects include the depletion of nutrients(1)(2) that you need such as:
• Coq10 Production
• Melatonin Production
The blocking of these two nutrients is particularly problematic because CoQ10 Depletion in Heart Failure is already seen as a BIG problem; and the depletion of melatonin can lead to increased aging and worsening sleep patterns in the elderly who often benefit from Melatonin for Sleep even when they Don't have heart problems.
Alternatives to Beta Blockers
While you should ALWAYS have the cooperation of your doctor if you would like to get off of any drug, it's especially important that you are under the care of a cardiologist and are being monitored carefully for any ill effects if you decide that it is in your best interest to stop taking beta blockers.
Having said that, there are some cardiologists who have had success getting people who are experiencing Beta Blocker Side Effects safely off of their medications. Dr. Rogers is one such doctor and says:
"I have found that most people can wean off beta-blockers and other high blood-pressure medications by increasing their Omega-3 (fish oil) and magnesium (700 mg a day or up to bowel tolerance). Some individuals will also need niacin (B3) at rather high doses."
Conventional Medical Therapies
Dr. Lindell is another doctor who has had much success in helping patients eliminate the underlying causes of their heart problems. His program, The Truth About Heart Disease outlines his findings from years of performing heart surgery and the methods that he has come to use instead of using drugs and surgery.
