Statins mainly play a role in lowering blood lipids, and the main statins that are less harmful to the liver are atorvastatin and rasulvastatin. But all statins, if taken in excess or for a long time, may cause liver function damage. Therefore, when taking statins, it is important to monitor liver function regularly. In addition to the side effects of liver damage, statins can also cause an increase in creatine kinase, which can damage the skeletal muscle system and cause muscle pain and weakness, so it is also important to monitor creatine kinase regularly. If a patient has abnormal liver function and elevated creatine kinase, reduce or discontinue the dosage of statins.
