Delavirdine is expected to raise the levels of atorvastatin, 
simvastatin and 
lovastatin. This expectation is supported by a case of rhabdomyolysis, which developed in a patient taking atorvastatin and 
delavirdine. 
 One of the manufacturers of 
simvastatin contraindicates delavirdine, and the US manufacturer of 
delavirdine advises against the use of either 
simvastatin or 
lovastatin. Patients should be made aware of the risks of myopathy and rhabdomyolysis, and asked to promptly report muscle pain, tenderness or weakness, especially if accompanied by 
malaise, fever or dark urine.
