Skeletal muscle toxicity, including rare rhabdomyolysis cases w/ or w/o renal failure; reduced transport proteins function; immune-mediated necrotizing myopathy. Patients carrying SLCO1B1 gene allele (c.521T>C). Carefully monitor patients for signs & symptoms of muscle pain, tenderness, or weakness, particularly during initial mth of combined therapy w/ niacin. Concomitant use w/ potent CYP3A4 inhibitors, breast cancer resistant protein (BCRP) inhibitors. Do not co-administer w/ fusidic acid. Do not measure creatine kinase following strenuous exercise or in presence of any plausible alternative cause of increased creatine kinase; re-measure w/in 5-7 days if significantly elevated at baseline (>5 x ULN). Patients w/ pre-disposing factors for rhabdomyolyis (eg, elderly ≥65 yr; female; renal impairment; uncontrolled hypothyroidism; hypoalbuminaemia; personal or familial history of hereditary muscular disorders; previous history of muscular toxicity w/ a statin or a fibrate; alcohol abuse) should measure creatine kinase levels prior to treatment. Discontinue treatment if myopathy is suspected. Temporarily discontinue therapy for few days prior to elective major surgery & when any major medical or surgical condition supervenes. Possible myopathy &/or rhabdomyolysis when co-administered w/ daptomycin; temporarily suspend daptomycin in patients w/ pre-disposing factors for myopathy or rhabdomyolysis. Monitor transaminase levels prior to treatment, every 3 mth during the 1st 12 mth of treatment, & thereafter periodically. Discontinue if AST & ALT levels increase to >3 x ULN; symptoms indicative & confirmed diagnosis of hepatitis (eg, jaundice, pruritus); interstitial lung disease develops. Patients who consume substantial alcohol quantities. Pancreatitis. Cognitive impairment. Monitor patients at risk of DM (fasting glucose 5.6-6.9 mmol/L, BMI >30 kg/m
2, raised triglycerides, HTN). History of pulmonary embolism. Not to be taken by patients w/ rare hereditary problems of galactose intolerance, Lapp lactase deficiency, glucose-galactose malabsorption; fructose intolerance, sucrase-isomaltase insufficiency. May cause allergic reactions due to sunset yellow FCF (E110). Dizziness may affect ability to drive & use machines. Mild renal insufficiency (estimated GFR 60-89 mL/min/1.73 m
