Gabapentin-Induced Liver Toxicity. Chahal, Japjot MD 1; Arif, Muhammad Osman MD 2; Achufusi, Ted George MD 1. Author Information Gabapentin isn’t known to cause liver or kidney problems. However, it can cause an allergic reaction called DRESS syndrome, which can lead to liver or kidney damage. But this is extremely rare. If you have existing kidney problems, your healthcare provider may start you at a lower gabapentin dose. Therapy with gabapentin is not associated with serum aminotransferase elevations, but several cases of clinically apparent liver injury from gabapentin have been reported. Some over-the-counter (OTC) medications and supplements can cause liver problems, too. Tylenol, weight-loss supplements, and green tea extract have all been linked to these types of issues. Signs of drug-induced liver injury (DILI) include abdominal pain and swelling, dark urine, yellowing of the skin and eyes, and changes in personality or Question. I have a patient with trigeminal neuralgia who was taking 1600 mg of gabapentin and had serious elevations of liver function tests (aspartate transaminase 258 U/L, alanine transaminase Gabapentin is not metabolized by the liver. Instead, it is excreted unchanged in your kidneys after circulating in your blood. Gabapentin affects nerves and chemicals in your body that are involved in some types of pain and in seizures. Gabapentin is an uncommon cause of DILI reported to cause a hepatocellular, cholestatic, or mixed picture of liver injury. Given the limitations of prior cases, we feel our report most closely ties gabapentin use to the resultant transaminase elevation. In rare cases, gabapentin can cause liver and kidney damage in dogs. Dogs with pre-existing liver or kidney disease may be more susceptible to these side effects. It is important to monitor your dog for any signs of liver or kidney problems while they are taking gabapentin. This article delves deep into the relationship between gabapentin and liver health, exploring mechanisms of action, potential side effects, case studies, and recommendations for monitoring liver function during treatment. Liver Issues: While generally not considered a major concern, gabapentin use has been associated with rare cases of liver damage, emphasizing the importance of liver function monitoring for those with existing liver conditions. Can Gabapentin cause liver damage in dogs? Quote from Veterinarian: “While Gabapentin is generally considered safe for dogs , there is a potential risk of liver damage with long-term use. It is important to monitor liver function tests periodically when a dog is taking Gabapentin to ensure that any potential issues are detected early.” Rare cases of liver and kidney damage have been reported with Gabapentin use. Individuals with pre-existing liver or kidney conditions may be at a higher risk. Regular monitoring of liver and kidney function is essential while taking Gabapentin. Magnetic resonance cholangiopancreatography showed no biliary abnormalities. After gabapentin was discontinued, liver enzymes began to downtrend with discharge values of AST 16, ALT 35, ALP 413, Tbili 9.3 and INR 1.1 (Figure). Discussion: Gabapentin induced liver injury is rare with few reported cases, many of which did not exclude other I found online somewhere that Gabapentin can inflame the liver, yet, also read that it is not metabolized in the liver at all. I read that incidents of liver problems are less than one percent as stated by Pfizer. Similarly, liver issues are uncommon but can occur in dogs with pre-existing liver conditions or those taking other medications that affect liver function. To minimize the risk of organ damage, regular blood work is recommended, especially for dogs on Gabapentin long-term .

Authors Japjot Chahal 1 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. Purpose: Trazodone and gabapentin are commonly used treatments. We report a rare case of trazodone and gabapentin-induced liver injury. Case: A 40-year-old woman with a history of depression presented jaundice. She had no other complaints. The patient denied risk factors for acute and chronic liver disease. Gabapentin, a common over-the-counter pain reliever and fever reducer, has been linked to rare individual case reports of liver injury. The causal relationship between gabapentin and liver damage is unclear, with the latency to onset being 1 to 8 weeks. For patients with existing liver issues or those taking multiple medications metabolized by the liver, consulting a healthcare provider about potential interactions is essential. Gastrointestinal side effects are common among gabapentin users.
