The UK manufacturers of 
tacrolimus suggest that all 
NSAIDs may have additive 
nephrotoxic effects with 
tacrolimus. Cases of 
renal failure have been reported in patients receiving the combination.  
Tacrolimus levels and/or effects (e.g. on 
renal function) should be monitored as a matter of routine, but it may be prudent to increase monitoring if 
NSAIDs are started.
