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. 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. 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.

Gabapentin Dosage Guidelines in Adults, Adolescents 12 Years of Age and Older with Renal Impairment 1-5. The starting dose is 300 mg three times a day. The recommended maintenance dose of gabapentin capsules is 300 mg to 600 mg three times a day. Dosages up to 2,400 mg/day have been well tolerated in long-term clinical studies. Doses of 3,600 mg/day have also been administered to a small number of patients for a relatively short duration, and have been well tolerated. Administer gabapentin For adults with normal kidneys: Nerve Pain/Restless Leg Syndrome: Start 300 mg once daily, increase to 300 mg 3 times a day. Max: 3600 mg per day. Seizures: Start with 300 mg 3 times a day, then increase to 600 mg 3 times a day. 4. Renal Dosing Recommendations. Dose Adjustment: 900 - 3600 mg/day TID. How Often to Take: 3 times a day. Download Table | Recommended dose adjustments based on varying degrees of renal impairment from publication: Rational dosing of gabapentin and pregabalin in chronic kidney disease | Mena Raouf,1 The recommended renal dosing for gabapentin is as follows: For patients with creatinine clearance ≥60 mL/min, the total daily dose range is 900-3600 mg/day, with a dose regimen of 300-1200 mg three times a day. The half-life of gabapentin immediate-release formulation is 5–7 hours in patients with normal renal function and is prolonged up to 52 hours in patients with CrCl<30 mL/min. 26 The half-life of pregabalin is 16.7 hours in patients with CrCl 30–59 mL/min, 25 hours in patients with CrCl 15–29 mL/min, and 48.7 hours in patients with CrCl<15 Since gabapentin is almost exclusively eliminated by renal excretion, the larger treatment effect observed in patients ≥75 years may be a consequence of increased gabapentin exposure for a given Drug dosing errors are common in patients with renal impairment and can cause adverse effects and poor outcomes. Doses often need to be reduced in renal impairment to prevent accumulation and toxicity. Examples of drugs that should be reduced in renal impairment are the gabapentinoids: gabapentin and pregabalin. Introduction Renal dose adjustments for gabapentin and pregabalin are ubiquitously evident in the medical literature. All manufacturers for these branded and generic dosage forms list dosing recommendations relative to creatinine clearance (CrCl) for both medications (Table 1).1,2 However, the basis of these recommendations has not been well articulated. Detailed Gabapentin dosage information for adults and children. Includes dosages for Restless Legs Syndrome, Epilepsy and Postherpetic Neuralgia; plus renal, liver and dialysis adjustments. Gabapentin and pregabalin are often used in patients with CKD primarily to treat neuropathic pain and restless leg syndrome and given the high prevalence of diabetes in this population, the proportion who receive these drugs is very high. In patients with normal renal function, the maximum dose of gabapentin is 3600mg daily in divided doses. Dose as in GFR=15–30 mL/min Potentially hazardous interactions with other drugsAntacids: reduce absorption Antidepressants: antagonism of anticonvulsive effect (convulsive threshold lowered) View gabapentin information, including dose, uses, side-effects, renal impairment, pregnancy, breast feeding, monitoring requirements and important safety information. Abstract Background: Gabapentin and pregabalin are well-tolerated medications primarily cleared by the kidney. Patients receiving higher gabapentinoid doses with decreased kidney function may be at an increased risk of adverse effects (AEs), but limited evidence exists evaluating gabapentinoid dosing and AEs in this population. Objective: To determine whether patients with decreased creatinine
