Doses >20 mg should be closely supervised during initiation & periodically re-evaluated for long-term risk/benefit. Asian patients. Consider dose reduction in patients w/ unexplained, persistent proteinuria during routine urinalysis testing; renal function assessment is recommended during routine follow-up of patients treated w/ 40-mg dose. Possible skeletal muscle effects (eg, myalgia, myopathy & rarely, rhabdomyolysis). Not to measure creatinine kinase (CK) following strenuous exercise or in the presence of a plausible alternative cause of CK increase, for possible confound result interpretation. Patients w/ pre-disposing factors for myopathy/rhabdomyolysis (eg, renal impairment; hypothyroidism; personal or family history of hereditary muscular disorders; history of muscular toxicity w/ another HMG-CoA reductase inhibitor, fibrate or niacin; alcohol abuse; age ≥65 yr; situations where increased plasma levels occur; concomitant use of fibrates or niacin). Measure CK levels in patients w/ inexplicable muscle pain, weakness or cramps particularly if associated w/ malaise or fever; discontinue if CK levels are markedly elevated (>10 x ULN) or if muscular symptoms are severe & cause daily discomfort. Temporarily w/hold in patients 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). Increased HbA1c & serum glucose levels. Excessive alcohol consumption &/or history of liver disease. Perform liver function tests prior & at 3 mth following both treatment initiation & any dose increase, & periodically (semi-annually) thereafter; monitor patients w/ increased transaminases; discontinue or reduce dose if serum transaminase level is >3 ULN. Concomitant use w/ various PIs in combination w/ ritonavir. Dizziness may occur during treatment; may affect ability to drive vehicles or operate machines. Moderate & severe hepatic impairment. Childn & adolescents 10-17 yr.
