If you are beginning treatment with atorvastatin, you will be relieved to know that research has found no link between any statins and sleep problems of any kind. Furthermore, a Lancet study in 2018 found that patients taking statins slept better, in terms of ability to fall asleep, amount of times they woke throughout the night, and in the overall quality of the sleep. That said, many doctors do receive complaints about sleep problems among patients taking statins. A generally accepted explanation for this is an opposite placebo effect. This means that patients are experiencing the negative side effects of drugs simply because they are expecting to, not because the drug is causing them. It is, however, possible that some patients may experience sleep disturbances due to joint pain, muscle pain, or other potential side effects.
