7 DRUG INTERACTIONS • Gemfibrozil : Avoid use with fluvastatin sodium extended-release tablets. ( 7.1 ) • Cyclosporine and Fluconazole : Avoid use with fluvastatin sodium extended-release tablets. ( 7.1 ) • Fibrates, Lipid-modifying doses (≥ 1 g/day) of Niacin, and Colchicine : Consider if the benefit of concomitant use with fluvastatin sodium extended-release tablets outweighs the increased risk of myopathy and rhabdomyolysis.

Lipid-modifying doses (≥1 g/day) of niacin increase risk of skeletal muscle effects. Fluvastatin dose reduction should be considered.

Since metabolic interactions are unlikely between nefazodone and HMG-CoA reductase inhibitors that undergo little or no metabolism by the CYP3A4 isozyme, such as pravastatin or fluvastatin, dosage adjustments should not be necessary.
