Causes, incidence, and risk factors

The liver helps the body break down certain drugs. However, the process is slower in some people, which can make them more likely to get liver damage. Even small doses of certain drugs can cause hepatitis, even if the liver breakdown system is normal. Large doses can overwhelm a normal liver.

Many different drugs can cause drug-induced hepatitis.

Painkillers and fever reducers that contain acetaminophen are a common cause of liver inflammation. These medications can damage the liver when taken in doses that are not much greater than the recommended dose.

Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, may also cause drug-induced hepatitis.

Other drugs that can lead to liver inflammation include:

• Amiodarone
• Anabolic steroids
• Birth control pills
• Chlorpromazine
• Erythromycin
• Halothane
• Methyldopa
• Isoniazid (used to treat tuberculosis)
• Methotrexate
• Statins

Symptoms

• Abdominal pain
• Dark urine
• Diarrhea
• Headache
• Jaundice
• Fatigue
• Loss of appetite
• Nausea and vomiting
• White or clay-colored stools

Signs and tests

Blood tests will be done to check liver function. Liver enzymes may be increased.

A physical exam may reveal an enlarged liver and abdominal tenderness in the right upper part of the belly area.
