These products can cause kidney failure or worsen kidney damage in people with certain risk factors. So, these should be avoided by people who have CKD, are over 55, or take medicines that affect blood flow to the kidneys – including NSAIDs, ACE inhibitors/ARBs, and diuretics. 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. From the Guidelines Gabapentin generally does not worsen renal function in patients with normal kidney function, but it requires dose adjustment in those with existing kidney impairment. The medication is primarily eliminated unchanged through the kidneys, which means it can accumulate to potentially toxic levels in patients with reduced renal function if not properly dosed 1. For patients Key Takeaways: Can Gabapentin Cause Kidney Problems? Gabapentin is primarily processed by the kidneys. Kidney function should be monitored during treatment. Dosage adjustments may be necessary for renal impairment. Some patients report mild kidney-related side effects. Consult a doctor if experiencing unusual symptoms. For people with normal kidney function, gabapentin is safe and doesn’t cause kidney complications or trigger kidney disease. In people with renal impairment, gabapentin can be harder to clear from the body. People with kidney disease may be prescribed gabapentin, but their dose will need to be lowered based on how well their kidneys function. This is a severe allergic reaction that can cause damage to major organs, including the liver and kidneys. If you have existing kidney problems, you may need a lower dose of gabapentin. This is because the kidneys help the body get rid of gabapentin. If you have impaired kidney function, gabapentin may build up in the body and cause side effects. Abstract Gabapentin is frequently used as an analgesic in patients with chronic kidney disease (CKD). It is excreted exclusively through kidney, and therefore impairment in kidney function could lead to gabapentin accumulation and hence toxicity. We present our experience of 3 cases with Gabapentin toxicity who were managed according to the severity of symptoms. Case 1: A 32-year-old male was Gabapentin is eliminated in urine unmetabolized at a rate proportional to creatinine clearance. 24 In patients with renal impairment, with unaltered gastrointestinal absorption, gabapentin half-life can be prolonged up to 132 hours (without dialysis), 30 placing patients with chronic kidney disease at an increased risk for toxicity. Gabapentin Effects on Kidneys | Is Gabapentin Bad for Your Kidneys? In this video we talk about Gabapentin effects on kidneys. The question we’re getting a lot is, Is gabapentin bad for kidney disease? Now, gabapentin is a medication used for diabetic neuropathy or neuropathy or any type of nerve pain. It is also used for seizures, but it’s given to a lot in people that have diabetic 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 a medication used to manage nerve pain (e.g., postherpetic neuralgia), restless leg syndrome, and seizures. Available as gabapentin capsules or extended-release tablets, it calms overactive nerves. 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 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. 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. View gabapentin information, including dose, uses, side-effects, renal impairment, pregnancy, breast feeding, monitoring requirements and important safety information. Gabapentin is primarily eliminated by the kidneys, and renal impairment can increase the risk of both gabapentin toxicity and edema. If the patient has pre-existing kidney disease or develops new kidney problems while on gabapentin, consultation with a nephrologist is recommended. Gabapentin clearance is directly proportional to creatinine clearance, and renal impairment reduces gabapentin excretion and increases plasma gabapentin concentrations in a linear fashion 8. The elimination half-life of gabapentin increases to 132 hours in patients on dialysis, compared to 5-9 hours in patients with normal renal function 8. 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. Abstract Background: 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. In fact, gabapentin is eliminated through renal excretion only, and since it does not bind to proteins, a single dialysis session will eliminate nearly 35% of the total. 8,9 In our case, this would explain the rapid improvement in symptoms.
