Pregabalin is an inhibitor of neuronal activity used for therapy of painful neuropathy and as an anticonvulsant. Therapy with pregabalin is not associated with serum aminotransferase elevations, and clinically apparent liver injury from pregabalin has been reported but appears to be quite rare. 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. Oxcarbazepine is a keto analogue of carbamazepine and, like the parent drug, is a potent anticonvulsant used alone or in combination with other agents in the therapy of partial seizures. Oxcarbazepine has been linked to rare instances of clinically apparent acute drug induced liver injury which resembles carbamazepine hepatotoxicity. Medications used to treat epilepsy may sometimes cause severe liver injury. However, several new medications have been approved over the last 2 decades and they may not be as toxic to the liver as older antiepileptic medications (AEDs). This study shows that overall liver injury due to AEDs is decre LiverTox became available online in April 2012 and was released officially as of October 1, 2012. At the time of release, the text of LiverTox contained over one million words, provided information on more than 650 medications, and included over 12,000 annotated references.

Show details Gabapentin (Neurontin) usually isn’t bad for your liver or kidneys. In most cases, it has little effect on these organs. In rare instances, gabapentin can cause DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome. 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. 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. DRESS was common with liver injury caused by lamotrigine, phenytoin, and carbamazepine, but not valproate or gabapentin. Liver injury severity was moderate to severe in the majority: five died, and three underwent liver transplantation (OLT). 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 is a long acting form of gabapentin that is used for restless leg syndrome and for painful postherpetic neuropathy. n engl j med 381;3 nejm.org July 18, 2019 267 Drug-Induced Liver Injury fatigue, and weakness, with subsequent confu-sion, stupor, and coma accompanied by liver Antiepileptics such as gabapentin and pregabalin are sometimes used to treat neuropathic pain. The LiverTox, an authoritative resource for drug-induced liver injury, classifies these 2 agents as class C, indicating that clinically apparent liver injury is uncommon. 55, 56 Mechanistically, both agents are likely safe to use in hepatic impairment, as they are primarily renally eliminated in an Major anticonvulsants include hydantoin derivatives, barbiturates, benzodiazepines, succinimides, valproic acid, gamma amino butyric acid (GABA) precursors and analogues, inhibitors of DMDA receptors and a multitude of miscellaneous recently introduced agents. LiverTox® provides regularly updated, unbiased and easily accessed information on the diagnosis, cause, frequency, clinical patterns and management of liver injury attributable to prescription and nonprescription medications and selected herbal and dietary supplements. Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor widely used as an antidepressant and for neuropathic pain. Duloxetine therapy can be associated with transient asymptomatic elevations in serum aminotransferase levels and has been linked to rare instances of clinically apparent acute liver injury. Nortriptyline is a tricyclic antidepressant that is also used in smoking cessation. Nortriptyline can cause mild and transient serum enzyme elevations and is rare cause of clinically apparent acute and chronic cholestatic liver injury. LiverTox ® provides regularly updated, unbiased and easily accessed information on the diagnosis, cause, frequency, clinical patterns and management of liver injury attributable to prescription and nonprescription medications and selected herbal and dietary supplements. 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 rep Drug induced liver injury is an uncommon but important and challenging form of liver disease. When evaluating a patient with new-onset liver disease, drugs, including prescription drugs, over-the-counter preparations, dietary supplements, vitamins and herbal medications, must always be considered as a possible cause. Indeed, the possibility must be entertained even if another cause may seem
