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 Gabapentin, a medication frequently prescribed for neuropathic pain and seizures, undergoes metabolic processing primarily by the kidneys, yet concerns persist about its potential impact on other organs. The liver, responsible for detoxification and drug Gabapentin, a gamma-aminobutyric acid (GABA) analogue, has infrequently been reported to cause liver injury; however, the causality in the previous reports is contested. Herein, we report a gabapentin-induced hepatocellular injury in a patient without another identifiable cause for acute liver injury. 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. Gabapentin induced liver injury is rare with few reported cases, many of which did not exclude other etiologies (1-3). In this case, the key elements of diagnosing DILI were met including gabapentin initiation closely preceding liver injury, other etiologies excluded, and discontinuation of gabapentin leading to improvement. In our patient there was a clear temporal association of liver injury occurring after our patient began gabapentin therapy, and slight improvement after a few days of discontinuation. Although further studies on this topic are needed, gabapentin should be considered as a cause of drug induced liver injury. 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. Tylenol, a common over-the-counter pain reliever, is not toxic to the liver when taken in moderation but can cause liver damage when used in Antiepileptic drugs (AEDs) are a common cause of drug induced liver injury (DILI). Over the last few decades, several newer AEDs were approved for marketing in the United States, and they are increasingly prescribed for indications other than Gabapentin is generally considered safe for the liver, but rare cases of liver damage have been reported. Gabapentin, a medication primarily used to treat nerve pain and seizures, has gained popularity for its effectiveness and relatively mild side effects. Gabapentin enacarbil is a long acting form of gabapentin that is used for restless leg syndrome and for painful postherpetic neuropathy. 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. Gapentin is an uncommon cause of DILI, reported to cause a hepatocellular, cholestatic, or mixed picture of liver injury. After gabapentin was discontinued, liver enzymes began to downtrend with discharge values of AST 16, ALT 35, ALP 413, Tbili 9. Gabapentin is eliminated through the kidneys and, therefore, doesn’t typically cause liver injury. Learn safe dosage recommendations for people with liver disease. Gabapentin was held. Thereafter, the man's liver function tests improved and remained stable. He discontinued gabapentin. He was advised to follow up outpatient. However, he was lost to follow-up. Based on clinical presentation and investigational findings, he was diagnosed with drug-induced liver injury attributed to gabapentin. Antiepileptic drugs (AEDs) are a common cause of drug-induced liver injury (DILI). Over the last few decades, several newer AEDs were approved for marketing in the United States, and they are increasingly prescribed for indications other than seizures. Contemporaneous data related to trends and characteristics of AED-related liver injury are sparse. Several cases reported that gabapentin might cause drug-induced hepatic injury in patients without co-existing cause of hepatic injury, and caused significant elevation in levels γ-glutamyl A drug-induced liver injury is one of the most common causes of acute liver failure. While acetaminophen is the most common etiology, other offending medications include amoxicillin-clavulanic acid, amiodarone, isoniazid, and fluoroquinolones to name a few. Gabapentin, a gamma-aminobutyric acid (GABA) analogue, has infrequently been reported to cause liver injury; however, the causality in the Gabapentin-Induced Liver ToxicityAm J Ther. 2022 Nov-Dec;29 (6):e751-e752. doi: 10.1097/MJT.0000000000001208. Epub 2020 Jun 5. Discussion: Gabapentin induced liver injury is rare with few reported cases, many of which did not exclude other etiologies. In this case, the key elements of diagnosing DILI were met including gabapentin initiation closely preceding liver injury, other etiologies excluded, and discontinuation of gabapentin leading to improvement. 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 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.
