This means that your kidneys degrade and remove medications from the body. When your kidneys aren't working properly, medications can build up and cause you harm. It's important to get your kidneys checked and to work with your doctor to make any adjustments to your medication regimen, such as dosing changes or substitutions. In most cases, gabapentin doesn’t hurt the liver or kidneys, though proper dosing is important to prevent side effects. Learn how gabapentin affects the liver and kidneys here. The straightforward answer is yes, you can potentially take gabapentin if you have stage 3 kidney disease, but with significant caveats. It’s crucial to understand that gabapentin is primarily eliminated by the kidneys, meaning that impaired kidney function can lead to a buildup of the drug in your system. 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. While not a primary cause, gabapentin can lead to complications that may indirectly affect kidney function. The drug’s reliance on renal elimination makes it more of a potential stressor for compromised kidneys rather than a direct nephrotoxin. Pharmacology. Gabapentin and pregabalin are commonly used first-line agents for diabetic peripheral neuropathy and other common neuropathies. Pharmacologically, both agents inhibit alpha-2-delta (α2δ) subunit of N-type voltage-gated calcium channels, a key receptor involved in regulating the excitability of neurons. 3 Peripheral nerve injury results in the upregulation of α2δ-1 receptors The patient had visited the Emergency Department two days before due to lumbosacral pain, was diagnosed with mechanical low back pain, and began treatment with 600mg gabapentin every 8 hours. Relevant medical history included smoking 1 packet/day, active use of multiple substances (alcohol, heroin, cocaine, etc.) and a recent hospital admission. 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. Gabapentinoids are eliminated from the body solely by the kidney, and pharmacokinetic studies show a stepwise prolongation in the elimination half-life of gabapentin and pregabalin as kidney function declines. 9, 10 Gabapentinoids should therefore be started at lower doses in patients with chronic kidney disease (CKD; guidelines are summarized In rare cases, people with preexisting kidney disease or kidney failure may experience potentially fatal toxicity when taking gabapentin. As with other painkillers, gabapentin misuse can Acetaminophen (Tylenol): For mild to moderate pain, acetaminophen remains a generally safe choice, although it should be used judiciously and at recommended doses. Opioids: Certain opioids like oxycodone, hydromorphone, fentanyl, methadone, and buprenorphine are generally considered safer to use in patients with kidney disease when used appropriately and under medical supervision. To protect your kidneys while taking Gabapentin, consider the following recommendations: Inform your healthcare provider about any pre-existing kidney conditions or medications you are taking. Stay hydrated by drinking an adequate amount of water throughout the day. 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. 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 most common gabapentin (Neurontin) side effects are dizziness and drowsiness. This may affect your ability to drive or perform other activities. Other gabapentin side effects include edema (fluid buildup), weight gain, and eye problems, but these aren’t as common. Rare but serious gabapentin side effects include mood changes in children. Experiencing severe side effects of gabapentin that Im beginning to think correlate with decreased kidney function. It’s becoming cyclic. Take normal dose of gabapentin until start to become confused and lethargic. Taper gabapentin and start to return to normal. Then hit with severe body pain back shoulders legs. Start increasing gabapentin. The short answer is: yes, gabapentin can be problematic for individuals with kidney failure and chronic kidney disease (CKD). While gabapentin is often prescribed for pain management, particularly nerve pain, and sometimes for seizures, its primary elimination pathway is through the kidneys. Misusing any pain medication can increase your risk of kidney damage. This includes aspirin, ibuprofen, acetaminophen, NSAIDs, and of course, prescription opioid medications. In recent years, gabapentin has been increasingly used off-label for expanded indications, including migraine headache, 1 phantom limb pain, 2 cancer-related pain, 3,4 spinal cord injury pain, 5 and a variety of neuropathic pain. 6,7 Off-label prescriptions, by some estimates, account for approximately 90% of gabapentin sales, 8 exceeding 2
