Gabapentin isn’t known to harm the liver. While there have been some individual reports of liver damage from gabapentin, it’s considered extremely rare. However, one possible side effect of gabapentin may cause liver damage. This side effect is a reaction called DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome. It’s 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. Does gabapentin affect liver function tests? Gabapentin is excreted unchanged in the urine. It does not affect the liver enzymes and has not been associated with hepatotoxicity. 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. Keywords: gabapentin, hepatotoxicity, drug-induced liver injury. Gabapentin and Cirrhosis of the Liver - Fatty 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. 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. Gabapentin caused elevated liver function enzymes AST, ALT, and ALP beside bilirubin. Gabapentin effects on lipid profile, Blood electrolytes, and functions of kidney and liver of laboratory 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 is a long acting form of gabapentin that is used for restless leg syndrome and for painful postherpetic neuropathy. Most research indicates that Gabapentin does not adversely affect liver enzymes or overall liver health in most patients. In fact, studies have shown that even patients with preexisting liver conditions can often tolerate Gabapentin without significant issues. 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 (GAB Hepatic metabolism converts OXC to its active metabolite monohydroxylated derivative. 32 Liver disease has no effect on the pharmacokinetics of OXC and monohydroxylated derivative. 33 OXC has not been associated with hepatotoxicity except for anecdotal case reports, but it can cause a modest elevation of liver enzymes. 34, 35, 36 One of the main concerns regarding Gabapentin is its potential impact on liver health. While rare, there have been reports of liver damage associated with the use of Gabapentin. These cases are typically seen in individuals with pre- existing liver conditions or those taking other medications that can affect liver function. 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. 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. 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. Vitamin E protects against gabapentin-induced chronic hepatic and renal damage associated with the inhibition of apoptosis and tissue injury in rats. It could be concluded the biochemical, morphological, and morphometric findings suggested that vitamin E coadministration is promising in attenuating the placental toxic effect of methotrexate. In this study, VIT E decreased the inflammatory and oxidative stress effect of methotrexate on the placental tissue by enhancing the level of eNOS. Therapy with gabapentin is not associated with serum aminotransferase elevations, but several cases of clinically apparent liver injury from gabapentin have been reported.
