Major Food Interaction
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Coadministration with grapefruit juice may significantly increase the plasma concentrations of lovastatin and simvastatin and their active acid metabolites. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. When a single 60 mg dose of simvastatin was coadministered with 200 mL of double-strength grapefruit juice three times a day, simvastatin systemic exposure (AUC) increased by 16-fold and simvastatin acid AUC increased by 7-fold. Administration of a single 20 mg dose of simvastatin with 8 ounces of single-strength grapefruit juice increased the AUC of simvastatin and simvastatin acid by 1.9-fold and 1.3-fold, respectively. The interaction has also been reported with lovastatin, which has a similar metabolic profile to simvastatin. Clinically, high levels of HMG-CoA reductase inhibitory activity in plasma is associated with an increased risk of musculoskeletal toxicity. Myopathy manifested as muscle pain and/or weakness associated with grossly elevated creatine kinase exceeding ten times the upper limit of normal has been reported occasionally. Rhabdomyolysis has also occurred rarely, which may be accompanied by acute renal failure secondary to myoglobinuria and may result in death.
ADJUST DOSING INTERVAL: Fibres such as oat bran and pectin may diminish the pharmacologic effects of HMG-CoA reductase inhibitors by interfering with their absorption from the gastrointestinal tract.
MANAGEMENT: Patients receiving therapy with lovastatin, simvastatin, or red yeast rice (which contains lovastatin) should be advised to avoid the consumption of grapefruit and grapefruit juice. Fluvastatin, pravastatin, pitavastatin, and rosuvastatin are metabolized by other enzymes and may be preferable alternatives in some individuals. All patients receiving statin therapy should be advised to promptly report any unexplained muscle pain, tenderness or weakness, particularly if accompanied by fever, malaise and/or dark colored urine. Therapy should be discontinued if creatine kinase is markedly elevated in the absence of strenuous exercise or if myopathy is otherwise suspected or diagnosed. Also, patients should either refrain from the use of oat bran and pectin or, if concurrent use cannot be avoided, to separate the administration times by at least 2 to 4 hours.

Drug Interaction Classification
|Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.|
|Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.|
|Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.|
|No information available.|
