Summary
Cyclosporine raises fluvastatin exposure and increases the risk of myopathy and rhabdomyolysis. The effect is dose related.
What this interaction means in plain words
Cyclosporin and Fluvastatin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Cyclosporin belongs to Miscellaneous; Fluvastatin belongs to Cardiovascular.
Why it happens
Cyclosporine inhibits hepatic uptake (OATP1B1) and possibly CYP2C9-mediated clearance of fluvastatin, increasing systemic levels.
What to do
Limit fluvastatin to 20 mg twice daily at most, or choose another lipid-lowering approach. Counsel patients to report unexplained muscle pain or weakness and check creatine kinase if symptoms occur.
