RX mirror: this is not independent corroboration of its underlying label. Check dated-label and formulation limitations.
Renal dosing, restrictions and evidence limits
No renal dosage change is required, including during hemodialysis, according to this source. The supporting renal study used immediate-release zileuton; less than 0.5% was removed by hemodialysis. That formulation distinction is retained rather than presenting the study as a direct extended-release trial. Hepatic restrictions and monitoring remain independent of the renal no-adjustment finding.
