Statins are prescription drugs that lower high levels of bad LDL cholesterol and are prescribed to prevent heart attacks and strokes. They are among the most commonly prescribed drugs worldwide, with brand names such as Lipitor, Mevacor, and Crestor. While statins are generally safe and effective, they can cause side effects such as muscle pain and cramping, which can range from mild to severe. In rare cases, statins have been linked to more serious musculoskeletal issues, including muscle rupture and a potentially life-threatening breakdown of muscle cells called rhabdomyolysis.

What You'll Learn
Statins and muscle pain
Statins are among the most commonly prescribed drugs worldwide, used to treat hyperlipidaemia. While statins are beneficial for many people, they can cause muscle pain and cramping in some patients. In rare cases, statins have been linked to muscle ruptures and a potentially life-threatening breakdown in muscle cells.
Dr Samia Mora, a cardiologist at Harvard-affiliated Brigham and Women's Hospital, estimates that about 15-20% of patients report muscle-related symptoms, with women being more likely to experience these side effects than men. Women tend to be older and have smaller bodies and more additional health issues than men when they start taking statins. They are also more prone to having undiagnosed low levels of thyroid hormone, which increases the risk of statin-related side effects.
If you are experiencing muscle pain while taking statins, it is important to keep track of any new symptoms and report them to your doctor. Your doctor may suggest a brief break from the drug to determine if your symptoms are caused by the statin. If you are taking statins preventatively, your doctor may also consider lowering your dosage or switching you to a different statin. Additionally, adding another type of cholesterol-lowering drug called ezetimibe (Zetia), which has not been associated with muscle pain, may allow your doctor to lower your statin dosage.
There are also some lifestyle changes you can make to help manage statin-related muscle pain. Committing to an exercise routine, losing weight if necessary, and adopting a heart-healthy eating plan, such as the Mediterranean diet, may enable you to reduce your statin dosage or even stop taking statins altogether. Additionally, if you have low thyroid hormone levels, taking replacement thyroid hormone pills may help alleviate muscle pain. Vitamin D supplements and coenzyme Q10 may also provide relief from muscle pain and cramping.

Statins and muscle rupture
Statins are among the most commonly prescribed drugs worldwide, used in the treatment of hyperlipidaemia and the prevention of coronary atherosclerotic disease. While generally well-tolerated, statins have been linked to musculoskeletal adverse drug reactions, with 10-15% of users experiencing related side effects.
Muscle rupture has been one of the reported side effects of statin use. The Netherlands Pharmacovigilance Centre's database has identified 15 cases of muscle rupture associated with statin use, while the EudraVigilance database contains 165 reports. Data from these spontaneous reporting systems suggest a plausible temporal association between statin use and muscle rupture.
Muscle rupture is a contraction-induced injury where muscle fibres tear due to a powerful eccentric contraction or overstretching of the muscle. This typically occurs during explosive movements like sprinting, lunging, or jumping. Spontaneous muscle ruptures without intense muscle contraction are very rare. In the reported cases, muscle ruptures occurred spontaneously, without any apparent physical strain or other aggravating factors.
The exact mechanism by which statins may contribute to muscle rupture is not fully understood. One theory suggests that statins weaken skeletal muscles by reducing cholesterol content in cell membranes. Another theory proposes that statins induce a sustained increase in cytosolic Ca2+ levels, leading to muscle dysfunction. Additionally, statins may cause a reduction in the availability of certain isoprenoid cometabolites, resulting in a decrease in the prenylation of specific proteins, which could lead to apoptosis of muscle cells.
It is important for physicians and patients to be aware of the potential association between statin use and muscle rupture. While statins are generally safe and effective, some individuals may be at higher risk for statin-induced myopathy due to factors such as age, genetics, and co-morbidities. Patients experiencing muscle-related symptoms while taking statins should consult their healthcare providers to weigh the benefits against the potential side effects and explore alternative treatment options if necessary.

Managing statin-related muscle pain
Although statins are among the most commonly prescribed drugs worldwide, they are associated with muscle pain and cramping in 15% to 30% of patients, according to some estimates. This side effect usually occurs within the first few months of starting the medication or raising the dose. While there are no proven remedies for statin-related muscle pain, the following strategies may help manage it.
Keep Track of Symptoms
Note any new symptoms that develop when you begin taking a statin and report them to your doctor. Your doctor may suggest a brief holiday from the drug to determine if your symptoms disappear when you're not taking it.
Exercise
There is some evidence that people who exercise regularly before taking statins are less likely to experience muscle pain and cramping. Gentle stretching may also relieve muscle cramps, but beginning a new vigorous exercise regimen while taking statins may increase the risk of muscle pain. If you're new to exercise, talk to your doctor about what's safe for you.
Lifestyle Changes
Adopting a heart-healthy diet and committing to an exercise routine may enable you to reduce your statin dosage or lower your cholesterol enough to stop taking statins altogether. A heart-healthy diet is typically high in fiber and low in saturated and trans fats, which can help lower your "bad" cholesterol (LDL). Aim for at least 150 minutes of moderate exercise per week to boost your "good" cholesterol levels (HDL).
Thyroid Blood Test
Muscle pain and weakness can be a sign of hypothyroidism. A simple blood test can check for low thyroid hormone levels, and taking replacement thyroid hormone pills may alleviate muscle pain and improve your lipid profile.
Supplements
If you have low vitamin D levels, restoring normal levels with a supplement may help reduce muscle pain and cramping. Some people also find relief with coenzyme Q10 supplements, although small clinical trials have not substantiated their effectiveness.
Alternative Cholesterol-Lowering Drugs
If muscle pain persists, ask your doctor about non-statin medications such as ezetimibe, bile acid sequestrants, PCSK9 inhibitors, or adenosine triphosphate-citrate lyase (ACL) inhibitors. These alternative medications can help lower cholesterol without triggering muscle pain.
It is important to remember that you should not stop taking statins without consulting your doctor. They can help you explore other treatment options or adjust your dosage to manage muscle pain effectively.

Statin side effects
Statins are prescription drugs that lower high levels of "bad" LDL cholesterol. They are among the most commonly prescribed drugs worldwide. Statins are generally safe and proven to reduce the odds of heart attack or stroke. However, they can cause some side effects, and statin-related muscle pain is the most common one. Statin-related muscle pain usually happens within the first few months of starting the medication or raising the dose. It may manifest as a constant soreness or weakness in the shoulders, thighs, hips, or calves. In most cases, the pain affects both sides of the body equally and can be mild or severe enough to interfere with daily life.
The exact cause of statin-related muscle pain is not well understood. However, there is evidence that statins may change how cells use energy or cause calcium and protein to leak out of muscles. Some people may be more sensitive to these changes. It is important to note that most statin-related aches are not harmful, but in rare instances, they can indicate more serious muscle damage. For example, a life-threatening condition called rhabdomyolysis has been linked to statin use, although this is very rare, occurring in a few people out of every million who take these drugs. Other possible side effects of statins include an increased risk of developing diabetes, particularly in those already at risk, and potential liver problems. Some people also experience difficulties with memory and reasoning, although there is no clear evidence directly linking statins to these issues.
If you are experiencing statin-related muscle pain, it is important to consult your doctor. They can advise you on strategies to manage the pain while continuing to lower your cholesterol. For example, your doctor may suggest lowering your statin dose or switching to a different statin. Additionally, supplementing with vitamin D or coenzyme Q10 may help reduce muscle pain and cramping. Regular exercise may also help alleviate statin-related muscle pain, but it is important to consult your doctor before starting a new exercise regimen.
It is important to remember that stopping statins without medical guidance can be dangerous and may increase the risk of heart-related health problems. If you are experiencing side effects, it is recommended to discuss them with your healthcare provider to determine the best course of action. They may suggest trying a different type of statin or adjusting the dosage to reduce or eliminate side effects while still maintaining the benefits of cholesterol-lowering treatment.

Statin alternatives
While statins are a commonly prescribed medication for lowering cholesterol, they may not be suitable for everyone due to potential side effects, such as muscle pain and, in rare cases, muscle rupture. In such cases, healthcare professionals may recommend exploring statin alternatives to help manage cholesterol levels effectively. Here are some alternative treatments to consider:
Ezetimibe (Zetia)
Ezetimibe is a cholesterol-lowering medication that can be taken with or without statins. It works by blocking the absorption of cholesterol from food in the stomach into the bloodstream. When used alone, ezetimibe lowers "bad" LDL cholesterol by 15 to 22%. However, when combined with a statin, it can further reduce LDL cholesterol levels by 21 to 27%. It is generally well-tolerated, but possible side effects include stomach pain, diarrhoea, flatulence, and tiredness.
Bempedoic Acid (Nexletol)
Bempedoic acid is an ATP citrate lyase (ACL) inhibitor that reduces cholesterol production in the liver, thereby lowering cholesterol levels in the blood. Unlike statins, bempedoic acid specifically targets the liver, reducing the risk of side effects like muscle pain. On its own, it lowers LDL cholesterol by 17 to 28%. When taken with ezetimibe, the combination can achieve around a 28% reduction in cholesterol levels.
PCSK9 Inhibitors
PCSK9 inhibitors are injectable medications that stop a protein called PCSK9 from working, allowing the liver to remove more "bad" LDL cholesterol from the blood. They have been shown to lower LDL cholesterol by up to 60%. PCSK9 inhibitors are recommended for individuals with heart and circulatory diseases who remain at high risk even after taking the maximum dose of statins. Leqvio (inclisiran) is a newer medication in this class, which blocks the PCSK9 enzyme by inhibiting the gene that produces it.
Fibrates (e.g., Gemfibrozil or Lopid)
Fibrates are another class of medication that can help lower cholesterol levels. An example of a fibrate is gemfibrozil (Lopid). Fibrates are often recommended in conjunction with statins or as an alternative when statins are not tolerated.
Bile Acid Sequestrants (e.g., Cholestyramine or Prevalite)
Bile acid sequestrants are another alternative to statins. They work by binding to bile acids in the intestine, preventing their reabsorption, and promoting their excretion. This, in turn, lowers cholesterol levels in the body.
It is important to consult with a healthcare professional before starting, stopping, or switching medications. They can advise on the most suitable treatment option based on your individual needs, medical history, and potential side effects.
