Remdesivir is an antiviral nucleotide analogue used for therapy of severe novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome (SARS) coronavirus 2 (CoV-2) infection. Remdesivir therapy is given intravenously for 3 to 10 days and is frequently accompanied by transient, reversible mild-to-moderate elevations in serum aminotransferase levels but has been only rarely linked to instances of clinically apparent liver injury, its hepatic effects being overshadowed by the systemic effects of COVID-19.


Remdesivir (rem de’ si vir) is a phosphoramidate prodrug of a substituted nucleotide analogue of adenosine which has potent activity against the SARS-CoV-1 and SARS-CoV-2 encoded RNA dependent RNA polymerases. Remdesivir is not well absorbed orally and must be given by intravenous infusion. Once absorbed into cells, remdesivir is modified by cellular esterases and then converted by kinases to the active triphosphate, which competes with ATP for incorporation into the nascent viral RNA chain resulting in “delayed” chain termination. In animal models of SARS-CoV-2 infection, prophylactic or early treatment with remdesivir ameliorated the subsequent viral infection and clinical disease. In a large, multinational randomized, placebo-controlled trial in humans, remdesivir was found to shorten the time to clinical recovery in patients hospitalized with COVID-19, but had little effect on overall mortality. In other studies, the effects of remdesivir on time to recovery were less clear and mortality rates as well as SARS-CoV-2 RNA levels were similar to those on placebo or no therapy. Soon after the initial favorable reports of remdesivir therapy of severe COVID-19, it received emergency use authorization (EUA) approval for therapy of patients hospitalized with severe COVID-19 which was later extended to all hospitalized patients with COVID-19, both adults and children. After the final results were obtained and a more in-depth review, remdesivir was given formal approval for use in hospitalized adults and children (12 years of age or older and above 40 kilograms in weight) with COVID-19. In early 2022, reports of successful prevention of progression of COVID-19 with early therapy of outpatients with confirmed SARS-CoV-2 infection led to the EUA of remdesivir for this indication in children 12 years of age or older and adults with symptomatic COVID-19 infection who are at high risk of complications. Therapy is recommended within 7 days of onset. Remdesivir is available in single-use vials of 100 mg, both as lyophilized powder and in solution (5 mg/mL) under the brand name Veklury. The typical intravenous dose in adults and children above the age of 12 is 200 mg on day one and 100 mg once daily thereafter for 5 to 10 days in hospitalized patients with COVID-19 pneumonia and for 3 days in outpatients with early symptomatic disease. Adverse events of remdesivir therapy include mild-to-moderate degrees of nausea and vomiting, headache, fatigue, renal dysfunction, serum aminotransferase elevations and rash. Rare instances of hypersensitivity reactions, acute renal dysfunction and liver injury have been reported.


In human volunteer studies, remdesivir therapy given for 7 to 14 days was associated with minor serum aminotransferase elevations (less than 5 times ULN) but without other evidence of hepatic injury. In controlled trials of remdesivir in patients hospitalized with COVID-19, rates of serum ALT elevations were similar or lower in patients receiving remdesivir than in those on placebo. Nevertheless, in most uncontrolled studies and case series, between 10% and 50% of patients treated with remdesivir developed transient, mild-to-moderate serum ALT and AST elevations within 1 to 5 days of starting therapy without changes in serum bilirubin or alkaline phosphatase levels. Elevations above 5 times ULN were reported in up to 9% of patients in several clinical trials, but the abnormalities resolved with discontinuation and were not associated with clinically apparent injury. With more widespread use of remdesivir for COVID-19, rare instances of marked ALT elevations with jaundice have been reported, but largely in patients who were critically ill with multi-organ failure or sepsis, or who had received other potentially hepatotoxic agents such as intravenous amiodarone (Case 2). Confounding the issue is that serum aminotransferase elevations are common during symptomatic SARS-CoV-2 infection (Case 1), present in up to 60% of patients and being more frequent in patients with severe disease and in those with the known risk factors for COVID-19 severity such as male sex, older age, higher body mass index and diabetes. Thus, serum aminotransferase elevations are common during remdesivir therapy but are generally asymptomatic, fully reversible and not associated with jaundice. With more widespread use of this antiviral in patients without severe or critical illness and with longer courses of therapy, features of hepatotoxicity may become more evident.

Likelihood score: D (possible uncommon cause of clinically apparent liver injury).

Mechanism of Injury

Serum aminotransferase elevations are not uncommon with parenterally administered remdesivir and may be caused by direct toxicity possibly due to inhibition of mitochondrial RNA polymerase. On the other hand, idiosyncratic injury due to remdesivir has not been clearly shown. SARS-CoV-2 virus may infect the liver and has been identified in hepatocytes by molecular techniques and electron microscopy, but the associated liver injury in these cases was mild. The receptor for SARS-CoV-2, the angiotensin-converting enzyme 2 (ACE2), is found on the surface of hepatocytes, although it is present in higher density on cholangiocytes. In the liver, remdesivir is metabolized by and is a substrate for CYP 3A4. It is also a substrate of the hepatocyte transporters p-glycoprotein and OATP1B1 and thus may be susceptible to drug-drug interactions with agents that inhibit or induce these enzymes and transporters.

Outcome and Management

The ALT and AST elevations associated with initiation of remdesivir therapy in patients with SARS-CoV-2 infection are generally mild-to-moderate in severity and self-limited in course without jaundice or symptoms. Careful monitoring of liver tests is recommended before and frequently during treatment. However, this recommendation is difficult in outpatient situations when the drug is given for 3 days only. Nevertheless, it is recommended that de novo elevations in ALT or AST above 10 times the upper limit of normal should lead to consideration of early discontinuation of the infusions. Furthermore, development of symptoms of hepatitis or jaundice should lead to immediate discontinuation. Restarting treatment can be considered once enzyme levels fall sufficiently, if there is no jaundice or symptoms and with careful monitoring. Use of other known hepatotoxins or potent inhibitors of p-glycoprotein should be avoided during remdesivir therapy.

Case 1. Acute anicteric hepatitis attributed to SARS-CoV-2 infection.(1)

A 59 year old woman with HIV infection (well controlled on antiretroviral therapy), hypertension, hyperlipidemia and Graves disease presented to an emergency room with fatigue and dark urine. She denied jaundice, abdominal pain, itching, rash or fever. Laboratory evaluation showed elevations in liver tests that had previously been normal including ALT 617 U/L, AST 1230 U/L, alkaline phosphatase 141 U/L, bilirubin 0.6 mg/dL, albumin 3.1 g/dL and INR 1.7. She had no history of liver disease or known recent exposures to viral hepatitis. Her other medications included Genoya (elvitegravir, cobicistat, emtricitabine and tenofovir alafenamide), clonidine, amlodipine, propranolol, hydrochlorothiazide, levothyroxine, fish oil and multivitamins. She was admitted for evaluation. She was afebrile and physical examination was normal. Tests for hepatitis A, B, C and E were negative as were assays for cytomegalovirus and Epstein Barr virus infection. Abdominal ultrasound showed a normal appearing liver without evidence of biliary obstruction or gallstones. A liver biopsy was not done. On hospital day 2 she developed fever and was found to have an oxygen saturation of 94% on room air. A nasopharyngeal swab was taken and proved to be positive for SARS-CoV-2 viral RNA. She was treated with hydroxychloroquine and remained minimally symptomatic and was discharged on hospital day 8, liver test abnormalities having improved but remaining mildly elevated.

This 59 year old woman developed an acute, mildly symptomatic hepatitis during an early, presymptomatic phase of SARS-CoV-2 infection. Other causes of acute liver injury were excluded and the episode was attributed to the SARS-CoV-2 infection. A striking finding was the predominance of AST over ALT elevations, a pattern that occurs with acute alcoholic hepatitis but is rare in acute hepatocellular injury due to medications or viral hepatitis. On the other hand, the aminotransferases were higher and the time to recovery was more rapid than occurs typically in acute alcoholic hepatitis. The case report did not mention alcohol use and liver biopsy was not done. One possible explanation for the prominent AST elevation was that part of the injury was due to muscle involvement. Transient elevations in serum aminotransferase levels are not uncommon during the course of symptomatic COVID-19 and in some cases AST elevations are greater than those of ALT. The degree of severity of the liver injury usually correlates with the degree of severity of the SARS-CoV-2 infection and occurs most frequently in men, the elderly and persons with obesity and diabetes. The occurrence of hepatic injury during the course of COVID-19 makes diagnosis of drug induced injury from therapies such as remdesivir challenging.

Case 2. Marked serum aminotransferase elevations and jaundice during remdesivir therapy of SARS-CoV-2 infection.(2)

A 68 year old woman with hypertension, diabetes, hyperlipidemia and coronary artery disease developed shortness of breath and chest pain and was hospitalized with suspected COVID-19 pneumonia. She was hypoxemic and had diffuse interstitial infiltrates but nasopharyngeal samples were negative for SARS-CoV-2 RNA. She had worsening symptoms and on day 4 underwent cardiac catheterization which showed severe, multivessel coronary artery disease. On day 6 she underwent successful 4-vessel coronary artery bypass surgery, but a repeat nasopharyngeal sample taken that day was positive for SARS-CoV-2, and she was transferred to a COVID-19 ward. Over the next few days, she had worsening oxygen requirements and pulmonary infiltrates and was started on remdesivir (200 mg loading dose followed by 100 mg daily intravenously). The following day she developed atrial fibrillation and was started on amiodarone infusions (150 mg loading dose, followed by 6 hours of 1.0 mg/min, followed by maintenance dosing of 0.5 mg/min). One day later serum ALT levels were above 5000 U/L and both remdesivir and amiodarone were stopped and intravenous N-acetyl cysteamine (iv NAC) was given. Her liver tests improved over the ensuing few days (Table) and she was discharged 2 weeks later.

A 68 year old woman suffered an acute coronary syndrome complicated by concurrent COVID-19. Therapy with remdesivir and amiodarone was rapidly followed by marked elevations in serum ALT and AST which fell after stopping both drugs (and administration of N-acetylcysteine). The marked elevations in both ALT and AST within 2 days of starting remdesivir is distinctly unusual and might well have been due to amiodarone that was started at about the same time. One possible explanation for the severity of the injury is that amiodarone altered the pharmacokinetics of remdesivir which is secreted from hepatocytes by p-glycoprotein, a hepatic transporter which is inhibited by amiodarone. A similar drug-drug interaction with precipitous adverse events occurs with the combination of sofosbuvir (another nucleoside analogue inhibitor of a viral RNA polymerase) and amiodarone, which results in severe bradycardia. Another explanation for the marked aminotransferase elevations would be shock, hypotension or hypoxemia which would cause acute hepatic necrosis. The case report is also somewhat unclear in regard to timing of the medications and the laboratory results.
