Therapeutic dosing targets of both medications have been established in clinical trials for neuropathic pain (gabapentin 1800–3600 mg/day; pregabalin 150–600 mg/day). Hemodialysis (CrCl ; 15 mL/min): Administer supplemental dose (range 125-350 mg) posthemodialysis, after each 4 hr dialysis interval; further dose reduction should be in proportion to CrCl Gabapentin elimination half-life is 5 to 7 hours and is unaltered by dose or following multiple dosing. Gabapentin elimination rate constant, plasma clearance, and renal clearance are Rational dosing of gabapentin and pregabalin in chronic kidney disease normal renal function on maximum recommended dosing yielded concentrations of 5–8 mg/L for gabapentin and ~ 2.8–8.2 mg/L for pregabalin. 22–25 The elimination half-lives of gabapentin and pregabalin are prolonged with renal impairment leading up to accumulation with The recommended maintenance dose of NEURONTIN in patients 5 to 11 years of age is 25 mg/kg/day to 35 mg/kg/day, given in three divided doses. NEURONTIN may be administered as the oral solution, capsule, or tablet, or using combinations of these formulations. The recommended dose of gabapentin in dialysis patients is 100 to 300 mg/per day, but on dialysis day an additional dose is given after the session, due to drug clearance through the dialysis membrane. We prescribed 300 mg/day (in a capsule), the minimum available dose of gabapentin in Greece. Hemodialysis: [<15 ml/min]: 100-300 mg/day. Give supplemental dose of 125-350mg after each dialysis. Dosage given should be proportional to maintenance dose. Patients receiving at least 300mg/day can be given the higher supplemental dose of 350mg after each dialysis. Other patients should receive a dosage at the lower end of this range. Gabapentin dosing guidelines for adult with renal impairment are summarized in Table 3. Dosing guidelines for gabapentin immediate-release are also applicable for adolescents 12 years of age and older with renal impairment. Detailed Gabapentin dosage information for adults and children. Includes dosages for Restless Legs Syndrome, Epilepsy and Postherpetic Neuralgia; plus renal, liver and dialysis adjustments. In patients with normal renal function, the maximum dose of gabapentin is 3600mg daily in divided doses. However, gabapentin is renally cleared and so the dose needs to be adjusted according to the GFR. For patients on dialysis, the recommended dose is 100-300mg post dialysis on dialysis days only. Child 6–11 years 10 mg/kg once daily (max. per dose 300 mg) on day 1, then 10 mg/kg twice daily (max. per dose 300 mg) on day 2, then 10 mg/kg 3 times a day (max. per dose 300 mg) on day 3; usual dose 25–35 mg/kg daily in 3 divided doses, some children may not tolerate daily increments; longer intervals (up to weekly) may be more appropriate, daily dose maximum to be given in 3 divided Max dosage 3600mg if patient already on gabapentin; Taper dose > 7 days to discontinue; Pediatric Dosing Partial seizures. Adjunct for partial seizures with out secondary generalization in patients> 12yo with epilepsy; also adjunctive therapy for partial seizures in patients 3-12 years <3 years: Safety and efficacy not established Dose Adjustment: 200 - 700 mg/day QD. How Often to Take: Once a Day; Notes: Careful monitoring is needed. End-Stage Renal Disease (ESRD) on Dialysis: Dose Recommendations: 100 - 300 mg / QD Daily Dose; Timing: After you get your dialysis treatment. Precautions: Your doctor will guide you on how much to take. 5. Peadiatric Renal Dosing For Children: DOSE IN RENAL IMPAIRMENT GFR (mL/MIN) 30–60 Start at low dose and increase dose according to response15–30 Start at low dose and increase dose according to response15 300 mg on alternate days or 100 mg at night initially, increase according to tolerability DOSE IN PATIENTS UNDERGOING RENAL REPLACEMENT THERAPIES A few small studies have suggested that pain is as common among peritoneal dialysis patients and stage 5 CKD patients who are not on dialysis as among chronic hemodialysis patients .

The recommended dose of gabapentin in dialysis patients is 100 to 300 mg/per day, but on dialysis day an additional dose is given after the session, due to drug clear-ance through the dialysis membrane. We prescribed 300 mg/day (in a capsule), the minimum available dose of gabapentin in Greece. However, on dialysis day we gave A third study compared gabapentin 900 mg/day, in three divided doses (N=111), and placebo (N=109). An additional gabapentin 1,200 mg/day dosage group (N=52) provided dose-response data. A statistically significant difference in responder rate was seen in the gabapentin 900 mg/day group (22%) compared to that in the placebo group (10%). In adults with postherpetic neuralgia, NEURONTIN may be initiated on Day 1 as a single 300 mg dose, on Day 2 as 600 mg/day (300 mg two times a day), and on Day 3 as 900 mg/day (300 mg three 2.3 Dosage Adjustment in Patients with Renal Impairment Dosage adjustment in patients 12 years of age and older with renal impairment or undergoing hemodialysis is recommended, as follows (see dosing recommendations above for effective doses in each indication): TABLE 1. NEURONTIN Dosage Based on Renal Function Renal Function Total Daily Dosages of drugs cleared renally should be adjusted according to creatinine clearance or glomerular filtration rate and should be calculated using online or electronic calculators.
