Summary
Both daptomycin and statins can cause skeletal muscle injury, and using them together may increase the risk of myopathy and rhabdomyolysis with CPK elevation. The risk is additive rather than pharmacokinetic.
What this interaction means in plain words
Daptomycin and Fluvastatin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Daptomycin belongs to Anti Bacterial; Fluvastatin belongs to Cardiovascular.
Why it happens
Additive myotoxicity of daptomycin and HMG-CoA reductase inhibitors; the mechanism is not fully established.
What to do
Monitor CPK weekly and for muscle symptoms during daptomycin therapy. Consider temporarily withholding fluvastatin if myopathy is suspected or CPK rises markedly.
