Statins are a commonly prescribed medication for lowering high levels of bad LDL cholesterol, thereby reducing the risk of heart attack and stroke. However, statin use has been associated with various side effects, the most common being muscle pain and cramping. This side effect usually occurs within the first few months of starting the medication or increasing the dose, and it can manifest as soreness or weakness in the thighs, hips, calves, or shoulders. While the exact cause of statin-related muscle pain is not fully understood, it is believed that these drugs may alter cellular energy usage or cause calcium and protein leakage from muscles. If you experience muscle pain while taking statins, it is important to consult your doctor, who may suggest adjusting your dosage, switching to a different statin, or exploring alternative cholesterol-lowering medications.

Statin-induced myopathy
Statins are one of the most widely used medications, known to reduce cardiovascular risk and mortality from cardiovascular disease. However, muscle pain and cramping are common side effects of statin use, with up to a third of statin users experiencing myopathy. Statin-induced myopathy refers to muscle-related symptoms that arise after starting statin therapy, including muscle pain, tenderness, weakness, and fatigue.
The exact mechanism by which statins cause muscle problems is not fully understood. One theory suggests that statins interfere with a protein essential for muscle health and growth. Another theory proposes that statins reduce coenzyme Q10 levels, leading to suboptimal muscle function due to insufficient energy. Additionally, statins may cause a release of calcium from muscles, resulting in symptoms such as muscle pain and weakness.
Several risk factors have been associated with statin-induced myopathy. These include being physically active, female gender, old age, a history of increased creatine kinase levels, a family history of myopathy, neuromuscular diseases, hypothyroidism, low vitamin D levels, and certain genetic factors.
If you experience muscle pain after starting statin therapy, it is important to consult a doctor or physician as soon as possible. A blood test is typically ordered to measure creatine kinase levels and rule out rhabdomyolysis, a life-threatening form of myopathy. In most cases, creatine kinase levels will be normal or mildly elevated. If other factors are contributing to the pain, the doctor may suggest a brief break from the medication to determine if the symptoms are due to statin usage.
There are several strategies to manage statin-induced myopathy. Lowering the statin dose or switching to a different statin may be considered. Additionally, adopting healthy lifestyle habits, such as moderate exercise, weight loss (if necessary), and a heart-healthy diet, can help reduce statin dosage or even eliminate the need for statins. While there are no proven remedies for statin-related muscle pain, some evidence suggests that regular exercise before taking statins may reduce the likelihood of experiencing muscle pain.

Managing muscle pain
While statins are safe and proven to reduce your odds of heart attack or stroke, muscle pain and cramping are their most common side effects. This side effect is more common in women than in men. If you experience muscle pain, do not stop taking your medication and consult your doctor. They will determine if your symptoms are due to the statin and suggest ways to ease the pain.
Statin-related muscle pain can be managed in several ways.
Exercise
Moderate exercise may protect against some of the statin-related side effects on your muscles. If you are new to exercise, consult your doctor about what type of exercise is safe for you. Gentle stretching may relieve muscle cramps, but beginning a new vigorous exercise regimen while taking statins may increase the risk of muscle pain.
Lifestyle changes
Lifestyle changes such as committing to an exercise routine, losing weight, and adopting a heart-healthy eating plan may help reduce your statin dosage or even lower your cholesterol enough to stop taking statins. The Mediterranean diet is an example of a heart-healthy diet. Even if a healthier lifestyle does not lower your lipid levels, it may still lower your long-term risk of heart disease and stroke.
Thyroid blood test
Muscle pain and weakness can be a sign of hypothyroidism. Getting a thyroid blood test can help determine if you have low thyroid hormone levels, which is more common in women. Taking replacement thyroid hormone pills may alleviate muscle pain and improve your lipid profile.
Supplements
Taking supplements to restore normal levels of vitamins such as vitamin D may help reduce muscle pain and cramping. Some people also find relief with coenzyme Q10, although small clinical trials have not substantiated its positive effects.
Change your prescription
If you have been taking statins for a few weeks and still experience muscle pain or cramping, consult your doctor about lowering your statin dose or switching to a different statin that is designed to be taken less frequently. Adding another cholesterol-lowering drug like ezetimibe (Zetia), which has not been associated with muscle pain, may also allow your doctor to lower your statin dosage.

Exercise and statins
Statins are mandatory in reducing lipid levels and cardiovascular (CV) risk. They are well tolerated by most people, but they can affect skeletal muscle, causing myalgia, creatine kinase (CK) elevations, and rhabdomyolysis. Statin-associated muscle symptoms (SAMS) are collectively referred to as "statin-associated muscle symptoms" (SAMS).
While statins can be beneficial for cardiovascular health, some people who take them may be concerned about the safety of exercising due to reports of SAMS. However, physical activity is essential for those prescribed statins, as they generally have more risk factors for cardiovascular diseases.
A study examined the effects of moderate exercise on statin users with and without muscle problems. The results showed that statin users experienced the same muscle-related effects from moderate-intensity exercise as those who didn't take statins. However, statin users took slightly longer to recover. Another study found that statin users can safely engage in a 12-week moderate-intensity exercise program without exacerbating muscle symptoms.
High-intensity exercise is not recommended for statin users, as it may increase the risk of muscle pain and injury. For example, a study found that lovastatin exacerbated skeletal muscle injury after treadmill walking but not after bicep curl exercises. Acute and chronic physical exercise may enhance the development of statin-related myopathy. Therefore, physicians should be cautious when prescribing statins to athletes or individuals engaging in regular intense exercise.
To summarise, while statins may cause muscle pain and other side effects, moderate-intensity exercise is generally safe for statin users and can provide additional cardiovascular benefits. However, high-intensity exercise and intense training programs may increase the risk of muscle-related issues. It is always recommended to consult a doctor before starting a new exercise routine while taking statins.

Non-statin medications
Statins are the first treatment for lowering high cholesterol and reducing the chance of a heart attack or stroke. However, they may not be suitable for everyone due to side effects, drug interactions, or statin intolerance. In such cases, non-statin medications can be considered as alternatives or adjuncts to statin therapy.
One such option is ezetimibe (Zetia), which can be taken with or without statins. Ezetimibe works by preventing the small intestine from absorbing cholesterol, causing the body to use cholesterol from the blood. It is often added when a patient is already on the maximum recommended dose of a statin but still has high cholesterol levels. It can also be combined with other statin alternatives like bempedoic acid (as Nexlizet) or with a statin in a pill called Vytorin (ezetimibe/simvastatin).
Fibrates like gemfibrozil (Lopid) are another class of non-statin medications. While their main benefit is in treating high triglyceride levels, they can also mildly lower LDL cholesterol levels. Bile acid sequestrants, such as cholestyramine (Prevalite), work by attaching to bile acids, preventing their reabsorption, and thereby lowering cholesterol levels. However, they may cause an increase in triglyceride levels, constipation, and stomach upset.
PCSK9 inhibitors are another class of medication effective in lowering LDL cholesterol. Natural and over-the-counter medications may also help manage cholesterol levels, but it is important to consult a healthcare professional to determine safe options.
In addition to medication, lifestyle changes such as a heart-healthy diet, weight loss if needed, and regular exercise can also help lower cholesterol levels and improve overall health.

Statin side effects
Statins are prescription drugs that lower high levels of "bad" LDL cholesterol. They are one of the most popular classes of prescription medications, with almost a third of U.S. adults over 40 taking a statin. Statins are safe and proven to reduce the odds of heart attack or stroke. However, they can cause side effects such as muscle pain and cramping, also known as statin-induced myopathy. This side effect can appear in a variety of ways, and many people don't experience it at all. The muscle pain usually happens within the first few months of starting the drug or raising the dose. It may affect the shoulders, thighs, hips, or calves, and can be mild or serious enough to interfere with daily life.
If you experience muscle pain while taking statins, it is important to inform your doctor as soon as possible. They will likely perform a physical exam and run tests to determine if the statin is the cause. If the statin is found to be the cause of the muscle pain, there are several management options that can be considered, including adjusting the dosage, switching to a different statin, or trying another type of cholesterol-lowering medication. Lowering the statin dosage may be effective in reducing muscle pain. Taking a temporary break from the medication, for example, stopping the drug for three to four weeks under medical supervision, can also help determine if the muscle pain is statin-related. If the pain disappears during this break, it is likely related to the statin.
In addition to adjusting the dosage or switching to a different statin, there are other cholesterol-lowering drugs that do not cause muscle pain and can be considered. Ezetimibe (Zetia) prevents the small intestine from absorbing LDL cholesterol and has not been associated with muscle pain. Bile acid sequestrants prevent the body from reabsorbing cholesterol from the bloodstream, while PCSK9 inhibitors help the body get rid of more LDL cholesterol by blocking a certain protein. Adenosine triphosphate-citrate lyase (ACL) inhibitors, such as Nexletol and Nexlizet, limit the liver's production of "bad" LDL cholesterol.
There are also lifestyle changes that can help manage statin-related muscle pain. Regular exercise may guard against some of the statin-related side effects on the muscles. However, it is important to note that beginning a new vigorous exercise regimen while taking statins may increase the risk of muscle pain. A heart-healthy diet, such as the Mediterranean diet, that is high in fiber and low in saturated and trans fats, can help lower "bad" cholesterol levels. Losing weight, if necessary, and adopting a heart-healthy eating plan may enable a reduction in statin dosage or even the discontinuation of statins.
