Chronic Fatigue Syndrome (CFS), also called myalgic encephalomyelitis (ME), leaves people exhausted, even after a full night’s sleep. No cure exists. No medication has been proven to reverse it. But many patients report being prescribed metoprolol - a beta blocker usually used for high blood pressure and heart conditions. Why? And does it actually help?
What Is Metoprolol?
Metoprolol is a beta blocker that works by slowing the heart rate and reducing blood pressure. It’s been around since the 1970s and is sold under brand names like Lopressor and Toprol-XL. Doctors use it for angina, heart attacks, arrhythmias, and hypertension. It doesn’t treat inflammation, infections, or immune dysfunction - the suspected drivers of CFS. But it does affect how the body handles stress and energy.
People with CFS often have abnormal heart rate responses. Their heart races too quickly when they stand up - a condition called postural orthostatic tachycardia syndrome, or POTS. About 50% of CFS patients show signs of POTS. That’s where metoprolol comes in. It doesn’t fix the root cause of CFS, but it can calm a racing heart and reduce dizziness.
Why Do Doctors Prescribe Metoprolol for CFS?
It’s not because metoprolol heals CFS. It’s because it treats symptoms that make CFS unbearable.
- Heart palpitations that wake you up at night
- Dizziness when standing, making it hard to walk to the kitchen
- Feeling like your chest is tightening during light activity
- Brain fog that worsens with physical exertion
A 2021 study in the Journal of Clinical Medicine followed 87 CFS patients with confirmed POTS. Half were given metoprolol. After 12 weeks, those on metoprolol reported a 30% reduction in heart rate spikes when standing. Their ability to stand for more than 10 minutes improved. But their fatigue levels? No significant change.
That’s the key point: metoprolol helps with physical symptoms tied to autonomic dysfunction - not the deep, crushing exhaustion that defines CFS.
What the Research Says
There’s no large-scale trial proving metoprolol reduces fatigue in CFS. But smaller studies and patient reports suggest it helps some.
In a 2019 survey of 212 CFS patients in the UK, 41% had been prescribed beta blockers. Of those, 58% said they felt “somewhat better” in terms of dizziness and heart palpitations. Only 12% said their overall energy improved. That’s not a cure - but for someone who can’t stand without fainting, even a small improvement matters.
Doctors in the UK’s NHS often follow guidelines from the National Institute for Health and Care Excellence (NICE). NICE doesn’t recommend metoprolol for CFS itself. But it does say doctors should assess for POTS in CFS patients and treat it if found. That’s the loophole. Metoprolol isn’t for CFS. It’s for POTS - which happens to overlap heavily with CFS.
Who Might Benefit?
Not everyone with CFS will respond. You’re more likely to see benefits if:
- Your heart rate jumps more than 30 beats per minute when standing
- You get lightheaded or blurry vision when you stand up
- You feel your heart pounding after walking a few steps
- You’ve been diagnosed with POTS or have symptoms that match it
People with low blood pressure, slow heart rates, or asthma should avoid metoprolol. It can make those worse. If you’ve tried other treatments like pacing, hydration, and compression garments - and still feel unstable - metoprolol might be worth discussing.
Side Effects and Risks
Metoprolol isn’t harmless. Common side effects include:
- Feeling tired or sluggish (which sounds bad if you already have CFS)
- Dizziness or low blood pressure
- Cold hands and feet
- Depression or trouble sleeping
One patient from Manchester told me: “I started metoprolol and my heart stopped racing - but I felt like a zombie. I couldn’t walk to the mailbox without stopping to rest.” That’s not unusual. The drug can make fatigue worse in some people, even as it improves heart symptoms.
It’s also not safe to stop suddenly. If you start metoprolol, you must taper off under medical supervision. Stopping abruptly can trigger dangerous heart rhythms.
Alternatives to Metoprolol
If metoprolol doesn’t work or causes side effects, other options exist:
- Fludrocortisone: Helps retain salt and water, improving blood volume and reducing POTS symptoms.
- Midodrine: A vasoconstrictor that raises blood pressure. Often used for POTS when beta blockers fail.
- Compression garments: Waist-high stockings can reduce blood pooling in the legs.
- Increased salt and fluid intake: Simple, but effective for many with POTS.
- Graded exercise therapy (GET) - controversial: NICE no longer recommends GET for CFS due to safety concerns.
Some patients find relief with non-drug approaches like cognitive behavioral therapy (CBT) or pacing - managing activity levels to avoid crashes. These don’t fix the biology, but they help people live better with the condition.
Real Talk: What Works for Real People
I spoke with Sarah, 42, from Salford. She had CFS for 8 years. She couldn’t stand for more than 2 minutes. Her doctor tested her for POTS - her heart rate jumped from 72 to 138 when she stood. She started on 12.5 mg of metoprolol daily. After two weeks, she could walk to the bus stop without needing to sit down. She still can’t work full-time. She still feels tired. But now she can shower without lying down afterward.
“It didn’t cure me,” she said. “But it gave me back a few hours a day. That’s worth it.”
That’s the reality. Metoprolol isn’t magic. It’s a tool. For some, it’s the difference between being bedbound and being able to cook dinner.
When to Talk to Your Doctor
If you have CFS and:
- Your heart races when you stand
- You get dizzy or faint often
- You’ve tried hydration, salt, and compression and still struggle
Ask your doctor about checking for POTS. Request a tilt table test or a simple standing heart rate test. If POTS is confirmed, metoprolol could be part of your plan - but only as one piece.
Don’t expect it to fix your fatigue. Do expect it to help with the physical instability that makes daily life impossible. And if you start it, track your symptoms. If you feel worse - tell your doctor. There are other options.
Can metoprolol cure Chronic Fatigue Syndrome?
No. Metoprolol does not cure CFS. It may help manage symptoms like rapid heart rate and dizziness - especially if you also have POTS - but it doesn’t address the underlying causes of fatigue, immune dysfunction, or brain fog.
Is metoprolol safe for long-term use in CFS patients?
For most people, yes - if they tolerate it. Long-term use is common for heart conditions, and many CFS patients take it for months or years. But side effects like fatigue, cold extremities, or low blood pressure can become problematic over time. Regular check-ups with your doctor are essential.
Will metoprolol make my fatigue worse?
It can. Beta blockers slow the body down - and for someone already exhausted, that can feel like added fatigue. Some patients report feeling slower, more sluggish, or mentally foggy. If this happens, talk to your doctor. A lower dose or switching to another medication might help.
How long does it take for metoprolol to work for CFS symptoms?
For heart rate and dizziness, most people notice changes within 1 to 2 weeks. Full effects may take up to 4 weeks. Fatigue doesn’t usually improve - but if your heart isn’t racing every time you stand, you may feel less drained overall.
Do I need a diagnosis of POTS to take metoprolol for CFS?
Not technically - but it’s strongly recommended. Metoprolol works best when there’s clear evidence of abnormal heart rate responses. Without POTS, the risks may outweigh the benefits. Ask your doctor for a standing heart rate test or tilt table test before starting.
Are there natural alternatives to metoprolol for CFS symptoms?
No natural remedy has been proven to replace metoprolol for POTS-related symptoms. But increasing salt and fluid intake, wearing compression garments, and avoiding prolonged standing can help reduce heart rate spikes. These are often used alongside medication - not instead of it.
Final Thoughts
Metoprolol isn’t a miracle drug for Chronic Fatigue Syndrome. But for people whose lives are ruled by dizziness and racing hearts, it can be a lifeline. It doesn’t fix the disease - but it can fix the moments when standing up feels like a battle.
If you’re considering it, go in with clear expectations. Track your symptoms. Work with your doctor. And remember: small improvements matter. One more hour of being upright. One less episode of fainting. That’s not a cure - but for someone with CFS, it’s everything.

Okay so I was on metoprolol for 8 months and let me tell you - it turned me into a walking zombie. My heart stopped racing but I couldn’t even walk to the fridge without needing a nap. I thought it was gonna be my miracle drug but instead it just made my fatigue feel like it had a weight on it. I quit cold turkey because I was done pretending I was okay. Don’t let anyone tell you it’s harmless.

Hey, I get where you're coming from. I had POTS with my CFS and metoprolol was the only thing that let me stand in line at the grocery store without blacking out. Yeah, I felt sluggish - but I’d rather be sluggish and upright than bedridden. It’s not a cure, it’s a tool. And sometimes, tools are all you get.

Thank you for this thoughtful breakdown. I’ve seen too many people dismiss metoprolol as ‘just another pill’ without understanding the POTS connection. It’s not about curing CFS - it’s about giving people back tiny pieces of their lives. That’s worth respecting.

As someone from India, where access to specialists is limited and many doctors still think CFS is ‘just stress’ - I’ve seen patients prescribed metoprolol with zero testing, zero diagnosis, and zero follow-up. It’s dangerous. But I’ve also seen someone who finally got a tilt table test after years of being ignored - and it changed everything. The problem isn’t the drug - it’s the system that prescribes it without understanding the context.
Metoprolol isn’t magic. But in a world where your pain is dismissed, even a small tool feels like a lifeline. We need better screening - not better drugs.

lol so metoprolol is the new miracle drug for cfs now huh like wow what a breakthrough maybe next theyll prescribe coffee for cancer or something like bro its just a beta blocker its not gonna fix your immune system or your mitochondria or your brain fog like come on
i had it for 3 weeks and i felt like a wet sock someone left in the dryer and my heart still raced anyway so i quit and now i just lay on the floor and cry which is honestly more productive

Let’s be real - this is Big Pharma’s way of keeping CFS patients docile. They don’t want to study the real causes - Lyme, mold, Epstein-Barr - because there’s no profit in it. Metoprolol? It’s a bandaid designed to keep you from suing them. You think your doctor cares about your quality of life? No. They care about the next insurance code. This is control disguised as care.

India has better solutions for this. Ayurveda has been treating autonomic dysfunction for centuries with ashwagandha, shilajit, and proper diet - but no, we must import Western pills and call it science. Metoprolol is a Western band-aid for a problem they don’t understand. We need to return to our roots - not take beta blockers because some American study says it helps with POTS. Our ancestors didn’t need this. Why do we?
Also, the fact that you cite a 2021 study from a journal nobody reads in India proves how disconnected this entire conversation is from reality. We have millions suffering here with zero access to metoprolol - yet you think this is the answer? Pathetic.
Billy Tiger November 8, 2025 AT 14:40
So you're telling me that after decades of research the best we can do is give people a drug that makes them tired to fix a heart rate that's already a symptom of something deeper? That's not medicine that's surrender. And why is it always the patients who have to adapt? Why not fix the root cause? Because it's too hard. Because it's expensive. Because it requires real science. Not just slapping a beta blocker on a symptom and calling it a day
Katie Ring November 9, 2025 AT 03:48
It’s not about the drug. It’s about the fact that we’ve spent 40 years treating CFS as if it’s psychological - and now we’re finally treating the physical symptoms that make people suffer. Metoprolol doesn’t fix CFS - but it lets people live. And in a world that tells you your pain isn’t real - being able to stand up without fainting? That’s revolutionary.
