Bempedoic Acid Gout Risk Calculator
Calculate Your Gout Risk
Gout is the most common serious side effect of bempedoic acid. This calculator helps you understand your personal risk based on your medical history.
What This Means For You
Gout occurs when uric acid builds up and forms crystals in your joints. It's a serious side effect of bempedoic acid that requires careful monitoring. If you have a history of gout, your risk increases significantly.
Your Calculated Gout Risk:
What You Should Do
Most gout flares happen within the first 4 weeks of starting bempedoic acid. If you experience:
- Swelling, redness, or burning pain in your joints
- Sudden pain in your big toe
- Difficulty walking or moving a joint
Stop the drug immediately and contact your doctor. Early treatment is critical to prevent permanent damage.

When your cholesterol won’t budge and statins make your muscles ache, bempedoic acid (sold as Nexletol) can feel like a lifeline. It’s designed for people who can’t take statins - and it works. But here’s the catch: it comes with risks you won’t find on a typical cholesterol pill. Gout flares. Tendon tears. Even liver stress. If you’re considering this drug, you need to know what’s really going on inside your body - not just the benefits, but the real, documented dangers.
How Bempedoic Acid Works (And Why It’s Different From Statins)
Bempedoic acid doesn’t work like statins. Statins block an enzyme called HMG-CoA reductase in the liver to cut cholesterol production. Bempedoic acid targets an earlier step - ATP-citrate lyase. That means it lowers LDL (bad cholesterol) without entering muscle tissue. That’s why it’s often chosen by people who get muscle pain, weakness, or cramps from statins. In clinical trials, muscle-related side effects dropped from 10-15% with statins to under 6% with bempedoic acid.
But here’s what most patients don’t realize: lowering cholesterol in the liver has side effects elsewhere. When the liver makes less cholesterol, it also changes how it handles uric acid. That’s where gout comes in.
Gout: The Most Common Serious Side Effect
One in every 67 people taking bempedoic acid will get gout. That’s 1.5% - more than triple the rate of placebo. For people who’ve had gout before, the risk jumps to 2.3%. That’s not rare. That’s common enough that your doctor should be talking about it before you even start the pill.
Gout happens when uric acid builds up and forms sharp crystals in your joints - usually the big toe. The pain hits fast: swelling, redness, burning so intense you can’t even sleep. Clinical trials show these flares often start within the first four weeks of taking bempedoic acid. It’s not just discomfort. It’s debilitating.
And here’s the kicker: many doctors don’t screen for it. The FDA requires baseline and 4-week uric acid checks, but not every prescriber follows through. If your uric acid level rises above 7 mg/dL, you’re at high risk. Prophylactic allopurinol (a gout-prevention drug) cuts gout risk by 65% in patients on bempedoic acid. Ask your doctor if you need it.
Tendon Rupture: A Silent, Devastating Risk
While gout is painful, tendon rupture is life-changing. In trials, 0.7% of people taking bempedoic acid had tendon injuries - seven times higher than placebo. That’s one in every 140 people. And if you’re taking it with a statin? The risk triples.
Tendons connect muscle to bone. The Achilles tendon in the heel is most vulnerable. Symptoms? A sudden “pop” or snap. Swelling. Bruising. Inability to stand on your toes. It’s not a strain. It’s a tear. And it often requires surgery.
People on fluoroquinolone antibiotics (like ciprofloxacin or levofloxacin) are at even higher risk. The European Atherosclerosis Society says to avoid bempedoic acid entirely if you’re on these drugs. Even if you’re not, any unexplained tendon pain - especially in the heel, shoulder, or wrist - should be treated as a red flag. Stop the drug. See a doctor. Don’t wait.
Other Side Effects You Can’t Ignore
Beyond gout and tendons, here’s what else shows up in clinical data:
- Back pain - nearly 5% of users report it, compared to 2.6% on placebo.
- Muscle spasms - 5.8% vs. 2.5%. Often mild, but can linger for weeks.
- Elevated liver enzymes - 2.2% of users had ALT or AST levels over three times normal. That’s liver stress. Monitoring every 3 months is required.
- Anemia - mild, in 1.8% of cases. Hemoglobin drops slightly, but rarely needs treatment.
- Upper respiratory infections - 7.7% of users got colds or bronchitis. Coincidence? Maybe. But it’s consistent across trials.
Some side effects fade. Muscle spasms often improve after 2-4 weeks. But tendon and gout risks don’t go away with time. They grow with use.
Who Should Avoid Bempedoic Acid?
This isn’t for everyone. Avoid it if you:
- Have a history of gout - especially if you’ve had multiple flares.
- Are currently taking fluoroquinolone antibiotics.
- Have a prior tendon injury or tendonitis.
- Already have liver disease or unexplained elevated liver enzymes.
- Are pregnant or breastfeeding - safety data is limited.
Even if you don’t fit these categories, you still need monitoring. Baseline blood tests. Uric acid check at 4 weeks. Liver function every 3 months. If your numbers creep up, your doctor should consider stopping the drug - not just adding more meds.
How It Compares to Other Cholesterol Drugs
Compared to ezetimibe (another non-statin option), bempedoic acid lowers LDL about the same - around 17-22%. But it’s worse on gout and tendons:
| Side Effect | Bempedoic Acid | Ezetimibe |
|---|---|---|
| LDL Reduction | 17-22% | 15-20% |
| Gout Risk | 1.5% | 0.7% |
| Tendon Injury Risk | 0.7% | 0.2% |
| Upper Respiratory Infections | 7.7% | 5.1% |
| High Liver Enzymes | 2.2% | 0.9% |
Statins still lower LDL more aggressively - up to 30-50%. But if you can’t tolerate them, bempedoic acid is the next best option. Just know you’re trading muscle pain for gout and tendon risks.
What to Do If You’re Already Taking It
If you’re on bempedoic acid and feel fine, don’t panic. But do this:
- Check your uric acid level - if you haven’t had it tested in the last 3 months, ask for it.
- Review your tendon health. Any recent heel, shoulder, or wrist pain? Tell your doctor.
- Don’t take fluoroquinolones (cipro, levaquin, etc.) without talking to your cardiologist.
- Stay active, but avoid sudden intense movements. Stretch your calves and shoulders daily.
- Report any sudden sharp pain, popping sound, or swelling in a joint or tendon - immediately.
Most people tolerate it fine. But the ones who don’t? They often wait too long to speak up.
The Bigger Picture: Is It Worth It?
The CLEAR Outcomes trial showed bempedoic acid reduces heart attacks, strokes, and heart-related deaths by 13%. That’s real. For someone with a history of heart disease who can’t take statins, that’s life-saving.
But if you’re young, have no heart disease, and just have high cholesterol? The risks might outweigh the benefits. The American Heart Association says bempedoic acid should be reserved for statin-intolerant patients - not used as a first-line option.
It’s not a miracle drug. It’s a tool. A tool with sharp edges. Use it only when necessary. Monitor it closely. And never ignore the warning signs.
Can bempedoic acid cause permanent tendon damage?
Yes. Tendon rupture can require surgery and lead to long-term mobility issues. The risk is low - about 0.7% - but once a tendon tears, it doesn’t heal perfectly. Early detection is critical. Stop the drug and get medical help at the first sign of pain, popping, or swelling.
How long does it take for gout to develop on bempedoic acid?
Most gout flares happen within the first 4 weeks of starting the drug. That’s why doctors are supposed to check your uric acid level at 4 weeks. If it’s high, starting allopurinol early can prevent attacks. Waiting until you’re in pain is too late.
Can I take bempedoic acid with statins?
Yes - but with caution. The combination (Nexlizet) is FDA-approved and lowers LDL more than either drug alone. But tendon rupture risk increases 3.5 times compared to placebo. If you’re on both, monitor for tendon pain and avoid fluoroquinolone antibiotics. Your doctor should weigh the extra LDL benefit against the higher injury risk.
Are there natural alternatives to bempedoic acid?
No natural supplement has proven LDL-lowering power equal to bempedoic acid. Plant sterols, soluble fiber, and omega-3s help slightly - but not enough for high-risk patients. If you need strong cholesterol control and can’t take statins, bempedoic acid remains one of the few evidence-backed options. Don’t replace it with supplements without medical guidance.
Should I get my liver tested while on bempedoic acid?
Absolutely. Liver enzyme elevations (ALT/AST) occur in 2.2% of users, and in 1.6% they rise above three times the normal limit. These are usually mild and reversible - but only if caught early. Blood tests every 3 months are standard. If your levels climb, your doctor may lower your dose or stop the drug.

Bro, I’ve been on Nexletol for 6 months and zero gout, zero tendon issues. Just lost 20 lbs of LDL and I’m hiking again. Stop fear-mongering. This drug saved my heart.

Okay but let’s be real-this article reads like a pharmaceutical warning label written by someone who’s never met a patient. Yes, gout risk is real. But so is the risk of dying from a heart attack at 52 because you refused statins and did nothing else. Context matters. If you’re middle-aged, have familial hypercholesterolemia, and your doctor’s monitoring you? This isn’t dangerous-it’s a lifeline. Stop treating every side effect like a death sentence.

Of course the FDA lets this through. Big Pharma’s got lobbyists in every committee. Meanwhile, real people are getting tendon ruptures and being told to ‘just take allopurinol.’ Like that’s a fix, not a bandaid on a bullet wound. And don’t even get me started on how they downplay the liver stress. You think your liver’s gonna thank you for forcing it to reroute metabolism? Please. This is just another profit-driven scam wrapped in clinical jargon.

I’m so glad someone finally laid this out clearly. My dad started this last year and had a gout flare within 3 weeks. We didn’t know to check uric acid-thank you for pointing that out. He’s on allopurinol now and doing way better. Just wish his doctor had mentioned it upfront. Knowledge is power.

Thank you for this. I’ve been hesitant to bring up tendon risks with my cardiologist because I didn’t want to sound paranoid. But after reading this, I’m scheduling a blood test for uric acid and liver enzymes next week. I’ve had minor heel stiffness since starting Nexlizet-I thought it was just from walking more. Maybe it’s not. I’m glad I’m not alone in worrying.

Let’s dissect this statistically. 1.5% gout? That’s 1 in 67. But 0.7% tendon rupture? That’s 1 in 140. Meanwhile, statins have a 0.1% rhabdo risk. So… statistically, bempedoic acid is more dangerous than statins on a per-patient basis. And yet, it’s marketed as ‘the safe alternative.’ That’s not just misleading-it’s predatory. If you’re going to prescribe this, you owe the patient a full risk-benefit breakdown-not a 3-minute spiel during a 10-minute visit. And don’t even get me started on the 7.7% upper respiratory infection spike. Coincidence? Or is the immune system being suppressed by hepatic metabolic rerouting? Someone needs to study that.

Wow. This is the most balanced, well-researched piece I’ve seen on bempedoic acid. The comparison table? Chef’s kiss. I’ve been telling my patients for months that ezetimibe is the safer non-statin option-until now, no one listened. Now I’m handing them this article. Thank you for doing the work the pharmaceutical reps won’t.

Oh please. Another ‘Big Pharma is evil’ sob story. You people act like gout and tendon tears are the end of the world. I’ve had three gout flares and two torn ACLs-I’m still alive, still working, still driving. This drug lowers your risk of stroke. That’s worth a little pain. If you can’t handle side effects, maybe you shouldn’t be on meds at all. Grow up. Stop whining.

While I appreciate the clinical rigor of this exposition, I must express my profound concern regarding the normalization of pharmacological risk mitigation as a substitute for systemic health reform. The fact that we are now debating whether a 0.7% incidence of tendon rupture is ‘acceptable’ in exchange for a 13% reduction in cardiovascular events reveals a fundamental epistemological failure in contemporary medical ethics. We have reduced human physiology to a series of statistically significant endpoints-while ignoring the phenomenological reality of lived suffering. Allopurinol, while pharmacologically efficacious, does not address the metabolic dysregulation precipitated by ATP-citrate lyase inhibition; it merely masks the symptom. And yet, we prescribe it as if it were a moral obligation. Where is the humility? Where is the reverence for the body’s intrinsic wisdom? This is not medicine. This is statistical dominion.
