Drug-induced Toxic Hepatitis

Toxic or Drug Induced Hepatitis


  • Included in the great number of agents known to be able to cause this type of hepatitis are common drugs and chemicals It is seen in up to 30 percent of patients who present with acute hepatitis and represents up to 10 percent of consultations by hepatologists[medicscientist.com]
  • Patients often present with fever, abdominal pain, and jaundice. Multiple serum lab values are often elevated, including AST, ALT, and GGT.[radiopaedia.org]
  • Younger patients present most commonly with a hepatocellular pattern of injury, whereas older patients mostly present with a cholestatic pattern of liver injury. 3 Some studies have found that women have a greater risk of developing DILI than men. 13[mdedge.com]
  • Always consider drugs as a cause of any patient presenting with hepatitis in order to provide early effective management.[patient.info]

  • If fever, rash, or pruritis occurs from any medication, its use should be stopped immediately.[hepatitiscentral.com]
  • More common in children Cholestatic type Idiosyncratic reaction Nausea, vomiting, fever, RUQ pain, jaundice, leukocytosis, elevated aminotransferases Clinical improvement upon drug withdrawal No evidence of CLD on follow up 19.[slideshare.net]
  • Drugs causing hypersensitivity reactions (eg, penicillin and procainamide) may be associated with fever, rash, and peripheral eosinophilia.[medicscientist.com]
  • A rash or fever may be part of some drug reactions that affect the liver. Treatment The only specific treatment for most cases of liver damage caused by taking a drug is to stop the drug that caused the problem.[m.ufhealth.org]
  • Other viral infections - eg, glandular fever, cytomegalovirus, HIV infection. Autoimmune hepatitis. Wilson's disease, haemochromatosis. Toxins - eg, alcoholic liver disease.[patient.info]
Gastric Lavage
  • Supportive measures Gastric lavage Activated charcoal or cholestyramine (prevent absorption); should be given within 30 mins N-acetylcysteine given within 8 hrs; loading dose-140/kg, ff by 70mg/kg q 4 hrs x 15-20 doses Survivors have no evidence of hepatic[slideshare.net]
  • Paracetamol poisoning is treated with gastric lavage and N-acetyl cystine which reduces hepatic necrosis, if therapy is started within 8 hours of ingestion. The main treatment for DILI is withdrawal of the offending drug[medicscientist.com]
  • Combination of estrogenic and progestational steroids; estrogen is primarily responsible Intrahepatic cholestasis Pruritus and jaundice Susceptible patients: idiopathic jaundice of pregnancy, family history Focal nodular hyperplasia, adenomas 20.[slideshare.net]

  • Patient 1 On July 16, 1992, a 42-year-old man visited his family physician for evaluation of scleral icterus and diffuse jaundice.[cdc.gov]
Dark Urine
  • Later, there may be jaundice and dark urine and an enlarged and tender liver. When the offending medication is withdrawn, symptoms may gradually subside. Reactions may be severe, however, and even fatal, even though the medication is stopped.[hepatitiscentral.com]
  • Some of the common symptoms are: nausea vomiting headache anorexia jaundice clay color stools dark urine hepatomegaly Diagnosis Diagnosis is typically made through a physical exam along with a patient history to identify any possible hepatotoxins.[medical-dictionary.thefreedictionary.com]
  • urine Diarrhea Fatigue Fever Headache Jaundice Loss of appetite Nausea and vomiting Rash White or clay-colored stools Exams and Tests You will have blood tests to check liver function.[m.ufhealth.org]
  • Later, overt evidence of liver damage, such as jaundice, dark urine and an enlarged and tender liver, may develop. Two general pathogenic mechanisms are recognised: Predictable or direct: usually promptly follows an exposure to a new medication.[patient.info]


  • The main treatment for DILI is withdrawal of the offending drug[medicscientist.com]

  • Treatment There isn't any specific treatment other than immediate discontinuance of the causative agent. Rest during the acute phase of the disease is vital along with the intake of fluids to maintain hydration.[medical-dictionary.thefreedictionary.com]


  • What is the Prognosis of Drug-Induced Hepatitis? (Outcomes/Resolutions) The prognosis of Drug-Induced Hepatitis is usually good.[dovemed.com]
  • Treatment and prognosis Treatment depends on the etiology of the acute hepatitis.[radiopaedia.org]
  • Prognosis Usually the symptoms will go away after the drug has been eliminated due to the liver repairing itself. A full recovery is typically expected unless it wasn't treated quickly resulting in more liver damage being done than normal.[medical-dictionary.thefreedictionary.com]
