Gabapentin doesn’t hurt the liver or kidneys in most cases. However, taking a safe gabapentin dose is important to prevent potential side effects. Introduction Gabapentin is an anticonvulsant medication, commonly used to manage neuropathic pain, and it also finds widespread off-label use in treating various pain and sleep disorders. Notably, gabapentin is exclusively excreted through the kidneys, making its dose reduction essential when given to patients with impaired renal function. 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. Neurontin - Gabapentin Renal Dosing protocol for Adults, maintenance gabapentin dosing and additional dosing for adults undergoing dialysis Key takeaways Gabapentin is a medication used to treat seizures, postherpetic neuralgia pain associated with shingles, restless leg syndrome, and diabetic neuropathy. For people with normal kidney function, gabapentin is safe and doesn’t cause kidney complications or trigger kidney disease. 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 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. Heightened awareness of such preventable risk, amid the chronic kidney disease epidemic Studies have shown that gabapentin toxicity can occur in patients with chronic kidney disease, particularly in those with advanced age and multiple comorbidities 4, 5. Dose Adjustment and Renal Function Dose adjustment of gabapentin is crucial in patients with decreased renal function to prevent toxicity 4, 5. Impaired kidney function (reduced creatinine clearance) increases drug accumulation, raising side effects risk. So, it's important to change the dose if your kidneys aren't working right. 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. 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. 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. 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. However, gabapentin is renally cleared and so the Gabapentin’s apparent total clearance is 100 mL/ min in adults with normal renal function, which is essentially equivalent to CrCl and does not suggest the involvement of tubular reabsorption.1 Some evidence suggest that active tubular secretion mediated by organic cation transporter-1 (OCT-1) may play a role in gabapentin’s renal clearance.

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. Gabapentinoids are opioid substitutes whose elimination by the kidneys is reduced as kidney function declines. To inform their safe prescribing in older adults with chronic kidney disease (CKD), we examined the 30-day risk of serious adverse events according to the prescribed starting dose. When kidney function declines, the clearance of Gabapentin can be affected, leading to increased levels in the bloodstream. For patients with normal kidney function, Gabapentin's half-life—approximately 5 to 7 hours—allows for effective dosing without significant accumulation. 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. 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.
