Renal dosing, restrictions and evidence limits
Renal impairment has not been studied sufficiently to establish a renal dose-adjustment regimen. Acute renal injury, including tubular necrosis and urinary calcium oxalate crystals, has been reported; some cases required hemodialysis. Monitor renal function, including BUN and creatinine, for seven days after treatment.
The red chromophore can cause analyzer-dependent interference, including falsely increased creatinine on some methods. It can also trigger false blood-leak detection and dialysis-machine shutdown. Alert the laboratory and dialysis team; an apparent creatinine rise requires interpretation in context, not automatic attribution solely to assay interference. These precautions do not justify delaying emergency antidote treatment.
