Some studies suggest that statins should be continued to reduce cardiovascular risk even if cholesterol levels are normal, while other studies highlight the need for managing statin intolerance and considering alternative treatments.

Statins are widely prescribed medications that effectively lower low-density lipoprotein cholesterol (LDL-C) and reduce the risk of cardiovascular events such as heart attacks and strokes . However, the question of whether one can discontinue statin therapy once cholesterol levels are normalized is complex and requires careful consideration of various factors.
Statins not only lower cholesterol but also significantly reduce the risk of major vascular events, including non-fatal myocardial infarction, coronary death, strokes, and coronary revascularizations . This benefit is observed even in individuals at low risk of vascular disease, suggesting that the protective effects of statins extend beyond cholesterol reduction alone . Therefore, discontinuing statins might increase the risk of cardiovascular events, even if cholesterol levels are currently normal.
While statins are generally well-tolerated, some patients experience side effects such as myopathy, myalgia, and, in rare cases, rhabdomyolysis . For those who develop significant side effects, alternative strategies such as switching to a different statin, adjusting the dosage, or using non-statin cholesterol-lowering agents may be considered . However, stopping statins without medical advice can lead to increased cardiovascular risk.
Clinical guidelines emphasize the long-term benefits of statin therapy in both primary and secondary prevention of cardiovascular disease. Even short-term discontinuation of statins can lead to adverse effects, such as increased cholesterol levels and reduced vascular repair mechanisms, particularly in patients with conditions like type 2 diabetes. Therefore, any decision to stop statin therapy should be made in consultation with a healthcare provider.
For patients experiencing side effects, healthcare providers may recommend monitoring creatine kinase (CK) levels and adjusting the statin regimen accordingly. In cases of severe side effects, discontinuation may be necessary, but alternative treatments should be explored to maintain cholesterol control and cardiovascular protection .
While achieving normal cholesterol levels is a positive outcome, discontinuing statin therapy without medical guidance is not advisable due to the potential increase in cardiovascular risk. The decision to stop statins should be based on a comprehensive evaluation of the patient's overall health, risk factors, and potential side effects, in consultation with a healthcare provider. The long-term benefits of statins in reducing cardiovascular events often outweigh the risks, making adherence to prescribed therapy crucial for ongoing health and well-being.
