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. 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. The purpose of this study was to assess serum concentrations of gabapentin in cats with chronic kidney disease (CKD) vs clinically healthy cats. Five healthy cats were enrolled in a pharmacokinetic study. A single 20 mg/kg dose of gabapentin was Although gabapentin is well known for its well recieved pharmacokinetics, it is exclusively eliminated renally, and patients with chronic kidney disease are at risk 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. 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. Conclusion: Appropriate dosing of GPs is particularly important to minimize the risk of adverse events in patients of older age, with a history of seizures, or concomitant antipsychotic use. There is a need for prescriber education given the high frequency of inappropriate GP dosing observed in patients with advanced kidney disease. 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. This study addresses specified outcomes in patients taking gabapentinoids with impaired kidney function compared to patients with normal kidney function. Minimal exclusion criteria allowed for the inclusion of patients with a wide range of CrCl and gabapentinoid dosing. Patients must speak with a health care provider for complete information about their health, medical questions, and treatment options, including any risks or benefits regarding use of medications. This information does not endorse any treatments or medications as safe, effective, or approved for treating a specific patient. Is gabapentin safe for cats with kidney disease? Yes, gabapentin is considered safe for use in cats with kidney disease when dosed appropriately and monitored closely by a veterinarian. 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. For patients with normal kidney function, Gabapentin's half-life—approximately 5 to 7 hours—allows for effective dosing without significant accumulation. However, those with compromised renal function may experience prolonged effects due to slower elimination rates. Gabapentin (Neurontin, Horizant, Gralise) usually isn’t bad for your liver or kidneys. In most cases, it has no harmful effect on these organs. In rare instances, gabapentin can cause DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome. Topical NSAIDs are efficacious in both acute and chronic pain, have minimal systemic exposure (2-3% of oral dose), and are safe in patients with kidney disease when used over limited surface area [101]. 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. 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. Rational dosing of gabapentin and pregabalin in chronic kidney disease Mena Raouf 1, Timothy J Atkinson 1, , Meredith W Crumb Gabapentin can affect kidney function, particularly in patients with pre-existing kidney problems, and requires dosage adjustments to prevent toxicity and potential kidney damage. According to the most recent study 1, gabapentinoids, such as gabapentin, can cause life-threatening drug accumulation and toxicity in patients with renal impairments.
