Gabapentin is a unique anticonvulsant that is used as adjunctive therapy in management of epilepsy and for neuropathic pain syndromes. Therapy with gabapentin is not associated with serum aminotransferase elevations, but several cases of clinically apparent liver injury from gabapentin have been reported. The risk of liver damage is higher for people with other liver infections, like hepatitis B, who have alcohol use disorder or who take other medicines that can damage the liver. But one study found that long-term ART doesn’t increase the risk of liver damage. 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 Gapentin is not metabolized by the liver, and its effects on the liver and kidneys are similar to previous studies. In rare cases, gabapentin can cause DRESS (drug reaction with eosinophilia and systemic symptoms). Other AEDs with rising and currently highest prescription rates were associated with few or no cases of liver injury including gabapentin (45.3 million), clonazepam (18.8 million), pregabalin (10.6 million), topiramate (9.3 million), and levetiracetam (7.7 million) and many of cases were judged as only “probable”. 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. 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. Changes in liver function may be attributed to free radical damage induced by gabapentin, as documented in this study, where the drug enhanced antioxidant defense systems and elevated liver NO ABSTRACT: Cirrhosis is a heterogeneous diagnosis that impacts liver function, including the metabolism and clearance of medications, but the exact effect remains unclear. Misconceptions and significant practice variability exist among healthcare professionals regarding analgesic use in patients with liver dysfunction. Herein, we report a gabapentin-induced hepatocellular injury in a patient without another identifiable cause for acute liver injury. Discontinuing gabapentin resulted in rapid reversal improvement in hepatocellular injury. Gabapentin enacarbil and gabapentin are associated with a low rate of transient serum enzyme elevations during treatment and with rare instances of clinically apparent liver injury. Gabapentin enacarbil (gab" a pen' tin) enacarbil (en" a kar' bil) is a prodrug of and long acting form of gabapentin. Gabapentin lacks liver metabolism; the mechanism by which it produces liver injury is still unknown; however, there are reports of hepatotoxicity associated with its administration, so its use must be individualized for each patient. The liver is the organ that is responsible for breaking down (metabolizing) most of the substances in a person’s system. However, gabapentin is one of the few drugs that is not metabolized by the liver; instead, it is primarily metabolized by the kidneys. There are several liver enzymes, but the ones that show liver damage from medications are aspartate transaminase (AST) and alanine transaminase (ALT). Medications may cause liver enzymes to be elevated without serious liver damage until they reach 3 to 5 times the normal levels. 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 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. 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. This class, which includes gabapentin and pregabalin, is not metabolized by the liver. Therefore, risks in patients with advanced liver disease are not greatly increased. However, there are case reports of pregabalin‐induced hepatoxicity. 4 Gabapentin and pregabalin are renally excreted, so dosages need to be adjusted for renal failure.
