Discontinue therapy if creatine kinase levels are markedly elevated (>10 x ULN) or if myopathy is diagnosed or suspected. Increased incidence of myositis & myopathy in patients receiving other HMG-CoA reductase inhibitors together w/ ciclosporin, fibric acid derivatives (including gemfibrozil), nicotinic acid, azole antifungals & macrolides. Caution in patients w/ pre-disposing factors for myopathy, eg, renal impairment, advanced age & hypothyroidism or situation where an increase in plasma levels may occur. Temporarily w/ hold in patient w/ acute serious condition suggestive of myopathy or predisposing to the development of renal failure secondary to rhabdomyolysis (eg, sepsis, hypotension, major surgery, trauma, severe metabolic, endocrine & electrolyte disorders or uncontrolled seizures). Reports of myopathy &/or rhabdomyolysis w/ coadministration of HMG-CoA reductase inhibitor & daptomycin. Reports of new onset or aggravated pre-existing myasthenia gravis or ocular myasthenia w/ statins. Caution in patients who consume excessive quantities of alcohol &/or history of liver disease. Not recommended in patients w/ moderate or severe hepatic impairment. Avoid combination therapy w/ gemfibrozil. Consider gallbladder studies & alternative lipid-lowering therapy if cholelithiasis is suspected in patient receiving Rosuzet & fenofibrate. Coadministration w/ fibrates (other than fenofibrate) is not recommended. Monitor INR when added to warfarin, another coumarin anticoagulant or fluindione. Increases in HbA1c & serum glucose levels w/ HMG-CoA reductase inhibitors. Increased rosuvastatin exposure in Asians compared w/ Caucasians. Not recommended in ped patients.
