Gabapentin and pregabalin are commonly used for neuropathic pain in CKD patients but are not fully understood as this population remains excluded from efficacy and safety trials. Renal adjustments for the gabapentinoids are prodigiously recommended in the literature. 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. Drug dosing requirements for antihypertensives in patients with chronic kidney disease are listed in Table 4. 4, 5 Thiazide diuretics are first-line agents for treating uncomplicated hypertension The starting dose range is 10 mg/kg/day to 15 mg/kg/day, given in three divided doses, and the recommended maintenance dose reached by upward titration over a period of Detailed Gabapentin dosage information for adults and children. Includes dosages for Restless Legs Syndrome, Epilepsy and Postherpetic Neuralgia; plus renal, liver and dialysis adjustments. 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 Medscape - Seizure dosing for Neurontin, Gralise (gabapentin), frequency-based adverse effects, comprehensive interactions, contraindications, pregnancy & lactation schedules, and cost information. 8. Should patients with stage 3 chronic kidney disease (CKD) avoid gabapentin? Not necessarily. While caution is needed, with appropriate dose adjustment and careful monitoring by a healthcare provider, gabapentin can sometimes be used safely in those with stage 3 CKD. However, open communication and regular check-ups are essential. The recommended maximal daily dose of gabapentin is 1,500 mg in people with grade 3 chronic kidney disease (CKD), 700 mg in those with grade 4 CKD, 300 mg in those with grade 5 CKD, and 100 to 300 Many analgesics that are typically used in the non-CKD population should not be used among patients with advanced CKD (ie, estimated glomerular filtration rate [eGFR] <30 mL/min/1.73 m 2; including those on dialysis). This topic reviews the epidemiology, assessment of pain, and management of pain among patients with advanced CKD. Loading dose of 300–400 mg in patients who have never received gabapentin. Maintenance dose of 100–300 mg after each HD : session and increase according to tolerability. The clearance of both gabapentin and pregabalin decreases and half-life (t ½) increases proportionately with worsening renal function, requiring renal dose adjustment (Tables 1 and Supplementary Table 1) [106-108]. Both medications should be dosed post-HD. 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: Gabapentin toxicity in patients with chronic kidney disease is underrecognized. Patients with chronic kidney disease often receive inappropriately high gabapentin dosage for their kidney function, occasioning overt toxicity; advanced age and comorbidity predispose these patients for toxicity. 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.

Usual initial gabapentin dose: 300mg q8h. Usual maintenance dose: 300-600mg q8h. Maximum dosage/day: 3600 mg. [15-29]: Dosage range: 200-700mg/day. [<15]: 100-300 mg/day. Use lower end of this range for CRCL <7.5 ml/min. TABLE 1. Gabapentin Dosage Based on Renal Function. TID = Three times a day; BID = Two times a day; QD = Single daily dose. a. Gabapentin dosing ranges from 100 to 3600 mg daily and pregabalin dosing is 25 to 600 mg daily. 1,2 Gabapentin and pregabalin exhibit greater than 90% kidney elimination and adjustments to dose and frequency are recommended for patients with chronic kidney disease (CKD). 1,2 For patients with a creatinine clearance (CrCl) below 60 mL/min, a Background: Gabapentinoids (GPs) are frequently prescribed in individuals with chronic kidney disease (CKD); however, their exclusive renal elimination warrants dose adjustments to decrease risk of toxicity. This study evaluated GP prescribing patterns and whether excessive dosing was associated with increased incidence of gabapentinoid-related Per Lexicomp, Gabapentin’s recommended dose in patients with renal impairment is as follows: CrCl >15 to 29 mL/minute: 200 to 700 mg once daily. CrCl 15 mL/minute: 100 to 300 mg once daily.
