Gabapentin and pregabalin are used for neuropathic pain in CKD patients but require renal adjustments. Gabapentin is widely used in the management of pain. It is entirely excreted through the renal system so this needs to be considered in any patient becoming acutely ill and developing renal failure. Gabapentin doesn’t hurt the liver or kidneys in most cases. However, taking a safe gabapentin dose is important to prevent potential side effects. 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 Gabapentin toxicity in patients with chronic kidney disease is underrecognized. Patients with chronic kidney disease often receive dangerously high gabapentin dosage for their kidney function, which can lead to all sorts of problems. An alternative we recommend instead of Gabapentin is Alpha Lipoic Acid. Detailed Gabapentin dosage information for adults and children. Includes dosages for Restless Legs Syndrome, Epilepsy and Postherpetic Neuralgia; plus renal, liver and dialysis adjustments. Gabapentinoids, including gabapentin and pregabalin, are frequently prescribed as opioid alternatives. Given that gabapentinoids are eliminated from the body by the kidney, we sought to determine the risk of serious adverse events in patients with chronic kidney disease who started a gabapentinoid at a higher versus a lower dose. Abstract 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 adverse events (GRAEs). Conclusion 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. 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. 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. 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. INTRODUCTION Pain is one of the most common and distressing symptoms among patients with chronic kidney disease (CKD) [1]. The prevalence of pain has been associated with substantially lower health-related quality of life and greater psychosocial distress, insomnia, and depressive symptoms [2-9]. Among hemodialysis patients, severe pain is also independently associated with shortened or missed 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. Dose as in GFR=15–30 mL/min Potentially hazardous interactions with other drugsAntacids: reduce absorption Antidepressants: antagonism of anticonvulsive effect (convulsive threshold lowered) 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 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. Gabapentin can be used by kidney disease patients, but dosage adjustments are critical. Learn how to safely use gabapentin with kidney issues and discover alternative medications.
