[Atorvastatin-induced anemia accompanied by elevated serum LDH levels].

A 68-year-old woman consulted us because of anemia and elevated LDH serum levels >1,000 U/l. No particular disease was observed by various screening tests. Since she was taking atorvastatin despite low cholesterol level, we discontinued the drug, which improved her complaints. We later experienced similar patients with hyperlipidemia induced by other drugs, such as rosuvastatin and pravastatin. These drugs are widely used in patients with hyperlipidemia and more recently in tyrosine kinase inhibitor users. It is important to monitor cholesterol levels and discontinue the drug use when they are unnecessarily administered.
