Pain is one of the most common and distressing symptoms among patients with chronic kidney disease (CKD) . 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 ]. It is entirely excreted through the renal system so this needs to be considered in any patient becoming acutely ill and developing renal failure. We describe a patient who developed significant deterioration in her conscious level due to iatrogenic gabapentin overdose. 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. .table_layout tbody td{ font-size:0.95em;} Usual Gabapentin Dosing (Adults) Usual initial gabapentin dose: 300mg q8h. Usual maintenance dose: 300-600mg q8h. Maximum dosage/day: 3600 mg Gabapentin Renal Dosing [>60 ml/min]: Give usual dosage : Dosage range: 400-1400mg/day (divided doses - Usually bid) : Dosage range: 200-700mg/day. : 100-300 mg/day. Use lower end of this range for CRCL Gabapentin is known to be effectively cleared by hemodialysis, but the efficiency of clearance by peritoneal dialysis (PD) has not been previously described. We report a case of gabapentin toxicity in a patient on long-term PD who was treated with continuous automated cycling PD. Rationale & Objective: Gabapentinoids are opioid substitutes whose elimination by the kid-neys 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 it comes to gabapentin and kidney disease, kidney disease sufferers should be aware of the risks that are involved in taking gabapentin with kidney disease. Gabapentin is actually toxic to the kidneys. Gabapentin is frequently used as an analgesic in patients with chronic kidney disease. Although gabapentin is well known for its well 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. Discussion: 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. We describe a patient who developed significant deterioration in her conscious level due to iatrogenic gabapentin overdose. Chronic kidney disease has become a global epidemic, and frequently its significance has been underestimated. 22, 23 The present study revealed several deficiencies in our current state of care for patients with chronic kidney disease who are receiving long-term gabapentin. First, the gabapentin dosage adjustment for these patients was 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. 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. In this case report, we present a patient with chronic renal impairment who experienced devastating myoclonic jerky movements shortly after increasing his gabapentin dose. Gabapentin is not metabolized or protein bound, and is cleared only by renal excretion in humans; it is unknown whether this is also true in cats. 7 In humans, it has been demonstrated that kidney disease significantly influences the pharmacokinetics (PK) of gabapentin, and a 60% and 85% decrease in gabapentin clearance is seen in moderate and Gabapentin is frequently used as an analgesic in patients with chronic kidney disease. Although gabapentin is well known for its favorable pharmacokinetics, it is exclusively eliminated renally, and patients with chronic kidney disease are at risk for toxicity. Existing literature on such risk is lacking. With a growing chronic kidney disease epidemic,22, 23 an increasing number of patients with chronic kidney disease will be exposed to gabapentin. This study demonstrates that gabapentin dosage for patients with chronic kidney disease has been insufficiently adjusted and that the risk of gabapentin toxicity has been underrecognized. Gabapentin (Neurontin) usually isn’t bad for your liver or kidneys. In most cases, it has little effect on these organs. In rare instances, gabapentin can cause DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome. This is a severe allergic reaction that can cause damage to major organs, including the liver and kidneys. Furthermore, the impact of gabapentin accumulation can be particularly pronounced in patients with end-stage renal disease (ESRD), where kidney function is severely impaired or virtually absent. Dialysis may help to some extent, but it often doesn’t clear gabapentin as effectively as healthy kidneys. 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.
