Discontinue treatment if pain or ache (myalgia) developed on calf, back or body muscles; transaminase level is >3x ULN; creatine kinase (CK) levels are markedly elevated (>5x ULN) or if muscular symptoms are severe & cause daily discomfort (even if CK levels are ≤5x ULN). Interrupt therapy if serious hepatotoxicity w/ clinical symptoms &/or hyperbilirubinemia or jaundice occurs during treatment. Not to be started if repeat test confirms baseline CK >5x ULN. Not to be used in patient w/ acute, serious condition suggestive of myopathy or predisposing to development of renal failure secondary to rhabdomyolysis (eg, sepsis, hypotension, major surgery, trauma, severe metabolic, endocrine & electrolyte disorders or uncontrolled seizures). Increased risk of rhabdomyolysis in high dosage, elderly, hepatic/renal impairment, chronic alcoholism, hypothyroidism. Increased risk of increased blood sugar levels; serum aminotransferase (ie, AST [SGOT], ALT [SGPT]) conc; HbA1c & fasting serum glucose conc; risk of developing DM. Myopathy & rhabdomyolysis w/ acute renal failure secondary to myoglobinuria; immune-mediated necrotizing myopathy. Transient dipstick +ve proteinuria & microscopic hematuria. Patients w/ predisposing factors for myopathy/rhabdomyolysis eg, renal impairment, hypothyroidism, personal or family history of hereditary muscular disorders, previous history of muscular toxicity w/ another HMG-CoA reductase inhibitor or fibrate, alcohol abuse, age >70 yr, situations where increased plasma levels may occur, concomitant use of fibrates; history of liver disease. Asian patients. Perform LFTs before treatment, & 6 & 12 wk after treatment initiation; every 6 mth in patients regularly receiving treatment. Treat secondary hypercholesterolaemia caused by hypothyroidism or nephrotic syndrome prior to initiating treatment. Consider confirmatory test w/in 5-7 days if CK levels are significantly elevated at baseline (>5x ULN). Consider dose reduction if unexplained proteinuria &/or hematuria persists. Concomitant use w/ digoxin & warfarin; colchicine. Increased risk of myopathy & rhabdomyolysis in concomitant use w/ azole antifungals (eg, ketoconazole, itraconazole), macrolides (eg, erythromycin, clarithromycin), HIV PIs (eg, indinavir, ritonavir, nelfinavir, saquinavir), verapamil, diltiazem, gemfibrozil, nicotinic acid, cyclosporine, amiodarone. May cause fetal harm. Discontinue treatment during pregnancy. Childn & adolescents ≥8 yr w/ homozygous familial hypercholesterolaemia.
