Presentation
HLA-DR6 was present in four of five patients (80%) with chlorpromazine hepatitis, compared to 22% in controls. In conclusion, the HLA phenotype does not contribute significantly to idiosyncratic drug-induced hepatitis considered collectively. [ncbi.nlm.nih.gov]
Reaction less dose dependent and more varied in latency, presentation, and course. [utahgastroblog.com]
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]

Entire Body System
- Malaise
These incidents usually occur during the first 6 months of treatment and are preceded by nonspecific symptoms such as malaise, weakness, lethargy, facial edema, anorexia, vomiting, and even loss of seizure control. [emedicine.medscape.com]
Initially, anorexia, nausea, and malaise may occur, followed by pruritus in some but not all patients. [clinicalgate.com]

- Kayser-Fleischer Ring
When suspicion remains or ceruloplasmin level is low, other tests such as 24-h urine collection for copper, slit-lamp eye examination for Kayser–Fleischer rings, serum copper levels, and genetic testing of the ABC B7 gene are indicated as outlined in [gi.org]
Urogenital
- Dark Urine
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]
Patients should be advised to promptly report any new onset symptoms such as yellowing of their eyes, abdominal pain / discomfort, nausea / vomiting, itching, or dark urine. [utahgastroblog.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. [mountsinai.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]
Symptoms of liver damage include 5, 18 : Dark Urine. Fever. Pain in the abdomen. Nausea. Vomiting. Headache. Diarrhea. White stools. Rash. Build-up of fluid in the abdominal cavity. Jaundice (yellowing of eyes and skin). Enlarged liver. Fatigue. [drugabuse.com]

A viral hepatitis was excluded and valproic acid treatment was stopped. Upon normalisation of the liver tests, temozolomide treatment was resumed without perturbation of the liver tests. [scholars.northwestern.edu]
Prognosis
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]
Outlook (Prognosis) Drug-induced liver injury most often goes away within days or weeks after you stop taking the drug that caused it. Possible Complications Rarely, drug-induced liver injury can lead to liver failure. [mountsinai.org]
The risk is higher in women. [ 6, 7 ] Prognosis Usually symptoms subside when the causative drug has been discontinued and drug-related hepatitis subsides within days or weeks after the offending drug is stopped. [patient.info]
