Fosphenytoin: monitor unbound phenytoin in renal disease

A change in protein binding can make total concentration alone misleading. This renal-monitoring summary does not supply an automatic percentage dose reduction.

Before applying: Confirm the product-specific population and administration instructions; use the selected unbound-monitoring advice.

Rxlist source

GlobalRPh RX List - CEREBYX

Product / population: CEREBYX parenteral fosphenytoin product. Age, indication and administration rates must remain product-specific.
Renal measure: Renal impairment and hypoalbuminemia; interpret unbound phenytoin rather than total concentration alone.

RX mirror: this is not independent corroboration of its underlying label. Check dated-label and formulation limitations.

Renal dosing, restrictions and evidence limits

Renal disease and hypoalbuminemia increase the unbound phenytoin fraction. Monitoring should use unbound concentrations. Conversion from fosphenytoin to phenytoin may increase without a corresponding increase in phenytoin clearance, increasing toxicity risk. Consider the phosphate load when phosphate restriction is required in severe impairment. This card supplies no automatic renal dose reduction or infusion-rate substitution.
