Renal dosing, restrictions and evidence limits
Renal pharmacokinetics have not been studied. Sodium exposure is relevant in renal impairment, hypertension or heart failure. Approximate sodium per total nightly XYREM dose: 3 g supplies 550 mg; 4.5 g supplies 820 mg; 6 g supplies 1,100 mg; 7.5 g supplies 1,400 mg; 9 g supplies 1,640 mg. These are sodium-content values, not renal dosing recommendations or starting doses. Consider total sodium intake and retain the formulation-specific indication, divided-dose and restricted-distribution instructions.
