GlobalRPh RX List - Valproic Acid (Depacon)
- Product / population
- Intravenous valproate sodium; renal pharmacokinetics and concentration interpretation, not a new seizure-treatment schedule.
- Renal measure
- Severe renal failure; the cited study used CrCl below 10 mL/min.
RX mirror: this is not independent corroboration of its underlying label. Check dated-label and formulation limitations.
Renal dosing, restrictions and evidence limits
The source describes reduced unbound valproate clearance in renal failure but concludes that a routine renal dose adjustment does not appear necessary. Protein binding is substantially reduced, so a total serum valproate concentration can be misleading. Interpret concentrations in their protein-binding and clinical context rather than escalating solely to correct a low total result. Hemodialysis typically lowers valproate concentrations by about 20% in the cited source; that observation does not define an automatic post-dialysis supplement.
