Beta-blockers might cause one to face various side effects, but they should only last for a few days and usually goes away after. The initial period of time can be a bit hard to adjust to, and your body might even take 2-3 weeks to adjust. The side effects can cause uneasiness, and if you’re suffering from some issues like asthma, diabetes, bronchospasm, etc., it can become more complex. You’ll have to closely watch the dosage you take and the side effects if they’re rising. This medicine can also interact with various drugs and cause issues. You’ll be fine as long as you’re closely monitoring your condition. 

Beta-blockers are prescription drugs often given to people to help manage their heart conditions such as high blood pressure.

But it also helps people suffering from migraine, glaucoma, anxiety, overactive thyroid, and essential tremor. 

Though it’s supposed to help those suffering from different issues taking this medication also brings a long list of side effects.

There are also warnings and cautions that doctor gives when prescribing this medicine.

So, even though it’s supposed to make you better, it might also make you feel uneasy sometimes. 

Many people might not follow the necessary precautions or take medicine in the wrong dosage or time, triggering these side effects. Let’s look at what goes wrong and the side effects one might suffer.

How beta-blocker works

Mostly suggested to patients suffering from high blood pressure, this medicine works by blocking the action of certain hormones in the nervous system, such as adrenaline.

This helps keep the fight and flight instinct at bay, which can be fatal for people suffering from various issues.

Everyone knows how our adrenaline kicks in when we are in danger or in a dangerous situation.

While this hormone is good and needed by people sometimes, it might not be for those suffering from high blood pressure, anxiety, or other issues.

If the body releases high adrenaline levels, it may increase the person’s heartbeat and cause excessive sweating and heart palpitations. 

This medicine then helps block the release of these hormones and reduce stress on the heart and the force of contractions of the heart muscle.

It takes off the pressure of the blood vessels in the heart, the brain, and the body. 

It also obstructs the production of angiotensin II, which is a hormone that the kidneys produce, and this relaxes and widens the blood vessels easing the flow of blood through them. 

Side effects of beta-blockers

This medication is supposed to help people in various ways when prescribed by their doctor, but just because you start taking it doesn’t mean you will feel your best.

While some people don’t feel the side effects, others might go through a lot of potential side effects, such as:

  • Slow heartbeat
  • Low blood pressure
  • Cold feet and hands
  • Fatigue
  • Nausea and vomiting
  • Weakness and dizziness
  • Abdominal pain
  • Constipation
  • Sleeping difficulties and disturbances
  • Erectile dysfunction
  • Memory loss
  • Confusion
  • Fluid retention

One needs to be careful when taking this medicine for the common side effects can make you feel uneasy. But the effects are usually there for a few days and not for the whole duration of the medical prescription.

If the side effects don’t go away after a few days and affect your quality of life, you should call your doctor.

Warnings for beta-blockers

Before prescribing this medicine to people, the doctor must ask for your complete medical history and the current medications you’re currently on.

Since this medicine slows down the production and basically blocks the adrenaline hormone, it can cause severe side effects if they aren’t aware of everything about you.

This includes your history of:

  • Asthma
  • Bronchospasm
  • Severe peripheral artery disease, including Raynaud’s disease
  • A slow heart rate
  • Uncontrolled heart failure
  • Diabetes 

Those who suffer from diabetes need to be careful when taking this medicine as it can hide the warning signs of low blood sugar.

You’ll constantly need to check your blood sugar levels when taking this medicine. 

Asthma patients need to be careful because beta-blockers can also cause asthma attacks, and your doctor needs to monitor your asthma and prevent attacks. 

Those who suffer from chronic lung diseases, such as bronchitis emphysema, or both diseases, known as chronic obstructive pulmonary disease (COPD), can take beta-blockers.

But they should be careful if they start having breathing problems and immediately call their doctor. 

So it becomes essential for the doctor to know about your medical condition before thinking of prescribing beta-blockers and the dosage to recommend.

Drug interactions

Beta-blockers might also interact with other drugs, and this is where you letting your doctor know about your current medications comes in handy.

If there’s a certain risk of any interaction, your doctor will not prescribe this medicine to you or might lower the dosage recommended.

Some drugs with which interaction is possible to include:

  • Anti-arrhythmics, for managing irregular heartbeats
  • Antihypertensives, for lowering blood pressure
  • Antipsychotics for treating severe mental health problems 
  • Clonidine for treating high blood pressure and migraine
  • Mefloquine to treat or prevent malaria

When to see the doctor

Some mild side effects might be observed by the patient taking beta-blockers but not for long.

If the effect persists for long, you might need to see the doctor immediately.

These include:

  • Shortness of breath
  • Trouble sleeping
  • Decreased libido
  • Depression

The issue with any medicine is that you need to take it how it’s prescribed.

When you fail to do so, it can impact you and cause various side effects, which includes:

  • Difficulty in breathing
  • Changes in vision
  • Dizziness
  • Irregular heartbeat
  • Confusion

You need to be careful about the dosage of this medicine and take the appropriate dosage at the right time that your doctor prescribes.

If it’s twice a day and you missed one dose, skip it altogether and continue from the next dosage.

An overdose of this medicine can also cause severe side effects, as mentioned above. 

Other issues when taking beta-blockers

Some brands of beta-blockers such as atenolol and metoprolol have reportedly been causing weight gain.

Fluid retention accompanied by weight gain could be a sign of heart failure or that your condition is getting worse.

Weight gain is also a common issue, and you could gain 2-3 pounds within a day or gain more than 5 pounds in a week accompanied by other symptoms.

Another issue faced by people is that their heart rate stays low, and since this medicine basically blocks off the release of adrenaline, it affects your heart rate even when it shouldn’t be affected.

For example, if you’re exercising, your heart rate is supposed to rise, but it might not do so when you’re taking this medicine. 

If you suddenly stopped taking it before, which you shouldn’t do in the first place, it can become increasingly difficult to start again.

In the beginning, it was difficult to adjust to this medication. When restarting, it’s difficult to determine the correct dosage. 

FAQs

What to expect when coming off beta-blockers?

When coming off beta-blockers, you need to do so gradually and not suddenly stop taking them, for they can cause more harm than help.

If you let go of them suddenly, the beta-blocker withdrawal can result in a rise in blood pressure and in patients with heart disease, chest pain, heart attack, and even sudden death.

The side effects might last for a week when you stop taking it. But if done under the guidance of a doctor, you can prevent most side effects and gradually get this drug out of your system.

Is long-term use of beta-blockers harmful?

Taking this medicine for the long term can also severely impact a patient.

They might start suffering from disorientation, short-term memory loss, emotional lability, inability to think or concentrate correctly, and decreased performance on neuropsychological tests used to measure a psychological function. 

What should you avoid when taking beta-blockers?

You should avoid drinking beverages that contain caffeine or over-the-counter medicines, antihistamines, and antacids that contain aluminum.

You should also avoid alcohol, for it can negatively impact your body and reverse the effects of the medicine.

To summarise

It’s difficult to adjust to beta-blockers initially for its side effects that can cause uneasiness.

The side effects usually last for days, and the heart needs to adjust to taking these medicines, which generally takes about a month.

But if you suddenly start taking them or stop taking them, that’s also difficult and can lead to adverse effects.

Letting go of this medication under the guidance of a doctor is the only way to ensure you don’t face any consequences.

Even though this medicine might have helped some people with their heart issues, getting off feels like a breath of fresh air because of all the complications they had to face while they were on it.
