Statins are prescription drugs that lower high levels of bad LDL cholesterol and are commonly prescribed due to their safety and proven effectiveness in reducing the odds of heart attack or stroke. However, statins can cause side effects such as muscle pain, formally known as statin-associated muscle symptoms or SAMS. This side effect usually occurs within the first few months of starting the medication or increasing the dose, with symptoms ranging from mild to severe. While the exact cause of statin-related muscle pain is not fully understood, it is believed that statins may change how cells use energy or cause calcium and protein leakage from muscles. If you experience muscle pain while taking statins, it is important to consult your doctor before discontinuing the medication. They can help determine the cause of the pain and suggest strategies to manage cholesterol while easing muscle discomfort.

What You'll Learn
The exact cause of statin-related muscle pain is unknown
While statins are generally safe and effective in reducing the risk of heart attack and stroke, they can cause muscle pain in some individuals. The exact cause of statin-related muscle pain remains unknown, but several theories and mechanisms have been proposed to explain this side effect.
One theory suggests that statins may interfere with the way cells utilize energy. Statins could potentially impact the release of calcium from muscles, leading to muscle pain and weakness. This theory is supported by a 2019 study that found a link between statin use and increased calcium release from muscles. Additionally, statins may cause a reduction in coenzyme Q10, a vital substance for optimal muscle function.
Another possible mechanism is related to protein leakage from muscles. Statins might interfere with proteins essential for muscle health and growth, leading to muscle pain and other symptoms. It is hypothesized that some individuals are more sensitive to these changes in cellular energy usage and protein leakage, resulting in varying levels of muscle pain.
It is important to note that not everyone experiences muscle pain when taking statins, and the side effect is often mild and manageable. For those who do experience muscle pain, it usually occurs within the first few months of starting the medication or increasing the dose. The pain can manifest as a constant soreness or weakness in the shoulders, thighs, hips, or calves, typically affecting both sides of the body equally.
If you experience muscle pain while taking statins, it is crucial to consult your doctor. They can help determine the cause of the pain and explore strategies to manage it while maintaining cholesterol-lowering treatment. This may include adjusting the statin dosage, switching to a different statin, or adding non-statin cholesterol-lowering medications that are not associated with muscle pain, such as ezetimibe or PCSK9 inhibitors.

Statins may change how cells use energy
While statins are safe and proven to reduce the odds of a heart attack or stroke, they can cause muscle pain in some people. This pain usually occurs within the first few months of starting the drug or raising the dose. However, not everyone experiences this side effect, and there is no known exact cause.
Research suggests that statins may change how cells use energy. Statins are known to inhibit the production of cholesterol in cells, but they may also inhibit an important element in the energy production of mitochondria, the energy-producing organelles found in almost all cells in the body. Mitochondrial dysfunction may be an early event in the pathophysiology of statin-induced myopathy, as evidenced by mitochondrial dysfunction even in asymptomatic statin users. Statins have been shown to slow the time to peak power output, which may be related to muscle pain.
The Effect of Statins on Skeletal Muscle Function and Performance (STOMP) trial found that more patients in the atorvastatin group than in the placebo group developed muscle complaints, but there were no differences in muscle strength and endurance, aerobic performance, or physical activity levels after 6 months of treatment. However, this trial only studied individuals who were new to taking statins, so the results may not apply to long-term statin users. Additionally, the trial did not investigate changes in mitochondrial content and function during statin treatment, which may be relevant to muscle complaints and exercise performance.
Despite these findings, other studies have found no evidence that statins reduce aerobic fitness or exercise performance, even after 12 weeks and 6 months of treatment. It is important to note that these studies may not have been long enough, as statin-induced changes may take longer to develop. While statins may change how cells use energy, the exact mechanism is still not fully understood, and more research is needed to determine the causality of statin-induced muscle pain and changes in muscle performance.

Calcium and protein may leak from muscles
Statins are prescription drugs that lower high levels of "bad" LDL cholesterol. They are generally considered safe and are prescribed to reduce the odds of heart attack or stroke. However, like many drugs, statins can cause some unwanted side effects, the most common of which is muscle pain or myopathy, a painful clinical disorder of the skeletal muscles. This side effect may occur in up to a third of statin users, according to the American College of Cardiology.
The exact cause of statin-related muscle pain is not fully understood. However, there are several theories to explain this phenomenon. One theory suggests that statins may interfere with the way cells use energy, causing changes in cellular energy utilization that lead to muscle pain. Another theory posits that statins could cause calcium and protein to leak out of muscles. This leakage may be due to statins' interaction with muscle cell components, such as mitochondria, or their impact on electrolytes, oxygen supply, or other factors affecting muscle health. Some individuals may be more sensitive to these changes, experiencing muscle pain, while others may not exhibit any noticeable aches.
The symptoms of statin-induced muscle pain can vary in severity, ranging from mild soreness or weakness in the shoulders, thighs, hips, or calves to more serious interference with daily life. In rare cases, statins can cause severe muscle damage known as rhabdomyolysis, which is a life-threatening condition. However, this occurs very rarely, affecting only a few out of every million people taking statins.
If you experience muscle pain after starting statin therapy, it is important to consult a doctor or physician as soon as possible. They can help determine if the pain is related to the statin medication and advise on appropriate next steps. Strategies to manage statin-related muscle pain may include taking a "statin vacation," adjusting the dosage, switching to a different statin, or exploring non-statin cholesterol-lowering drugs. It is important not to stop taking your medication without consulting a healthcare professional.
While statin-induced muscle pain is a known side effect, it is important to remember that not everyone experiences it. The occurrence and severity of muscle pain can vary between individuals, and in some cases, the pain may lessen or resolve over time as the body adjusts to the medication. Moderate exercise may also help guard against statin-related muscle pain, but it is advisable to consult a doctor before starting a new exercise routine.

SAMS (Statin-Associated Muscle Symptoms) affect 7-29% of people
Statins are prescription drugs that lower high levels of "bad" LDL cholesterol. They are commonly prescribed because they are safe and proven to reduce the likelihood of heart attacks or strokes. However, statins can cause muscle pain in some people. This side effect is known as Statin-Associated Muscle Symptoms (SAMS).
SAMS affect 7-29% of people taking statins, according to patient registries and observational studies. It is one of the principal reasons for discontinuing statin treatment, which can lead to an increased risk of cardiovascular events. SAMS can manifest in various ways, ranging from mild weakness and cramps to severe and rare cases of rhabdomyolysis, a life-threatening type of myopathy. Most commonly, SAMS presents as muscle pain or aching without a significant increase in creatine kinase, an enzyme released from damaged muscle cells.
The exact cause of statin-related muscle pain is not fully understood. However, it is believed that statins may interfere with proteins essential for muscle health and growth, leading to a release of calcium from muscles and causing symptoms such as pain and weakness. Some individuals may be more sensitive to these changes, resulting in SAMS. It is worth noting that not everyone experiences muscle pain when taking statins, and the symptoms can vary in severity and timing.
If you experience muscle pain while taking statins, it is important to consult your doctor. They can help determine if the pain is related to the medication and advise on strategies to manage the pain while continuing to lower cholesterol levels. In some cases, adjusting the statin dose or exploring alternative cholesterol-lowering drugs may be recommended.
In summary, Statin-Associated Muscle Symptoms (SAMS) affect a significant number of people taking statins, and it is a clinically relevant issue that requires careful management. Further research is ongoing to better understand the underlying causes and improve therapeutic approaches for patients experiencing SAMS.

Exercise may prevent statins from causing muscle damage
While statins are safe and proven to reduce the odds of heart attack or stroke, they can cause muscle pain and, in rare instances, serious muscle damage. Statin-related muscle pain usually occurs within the first few months of taking the drug or increasing the dose. However, research on animals and humans has shown that moderate exercise may help prevent statins from causing muscle damage.
Regular physical activity, consisting of at least 150 minutes of moderate exercise weekly, can increase "good" HDL cholesterol levels. This may, in turn, reduce the required dosage of statins, thereby lowering the likelihood of muscle pain. It is important to consult with a doctor about safe exercise routines, especially for those new to physical activity.
Additionally, long or intense exercise routines may increase muscle pain, and it is recommended to skip statins for a day or two before engaging in serious exercise, such as a marathon. It is also crucial to note that muscle pain may be a symptom of hypothyroidism, and a simple blood test can help determine if thyroid issues are the cause.
If muscle pain persists, there are alternative cholesterol-lowering drugs available, such as Ezetimibe, bile acid sequestrants, PCSK9 inhibitors, and Adenosine triphosphate-citrate lyase (ACL) inhibitors. These options can be discussed with a doctor, who can advise on the most suitable course of treatment while managing any side effects from statins.
In summary, while statin-related muscle pain is a known side effect, it is not universally experienced, and exercise may help mitigate this issue. It is important to consult with a doctor to find the best approach for managing cholesterol and maintaining overall health.
