From the Guidelines
The primary treatment for hyperbilirubinemia in adults involves addressing the underlying cause, with medications such as ursodeoxycholic acid (UDCA) for cholestatic hyperbilirubinemia, phenobarbital for severe hemolysis, and antiviral medications for hepatitis, while discontinuing offending agents in drug-induced cases.
Treatment Approach
The treatment of hyperbilirubinemia in adults is highly dependent on the underlying etiology, which can range from unconjugated hyperbilirubinemia (e.g., Gilbert's syndrome) to conjugated hyperbilirubinemia due to biliary obstruction or hepatocellular disease 1.
- For unconjugated hyperbilirubinemia, such as in Gilbert's syndrome, typically no specific medication is required, as it is often a benign condition that does not necessitate treatment beyond reassurance 1.
- In cases of drug-induced or hepatocellular hyperbilirubinemia, the first step is to discontinue the offending agent, which can lead to resolution of the hyperbilirubinemia 1.
- For severe hyperbilirubinemia due to hemolysis, phenobarbital at doses of 60-180 mg/day in divided doses can be utilized to enhance bilirubin conjugation and excretion, although this is less common in adults compared to neonates 1.
- Cholestatic hyperbilirubinemia, which can result from primary biliary cholangitis, primary sclerosing cholangitis, or medication-induced liver injury, may be treated with ursodeoxycholic acid (UDCA) at doses of 13-15 mg/kg/day to improve bile flow 1.
- In primary biliary cholangitis, UDCA at doses of 13-15 mg/kg/day is considered the standard treatment, aiming to slow the progression of the disease and improve symptoms 1.
- For hyperbilirubinemia associated with hepatitis, the choice of antiviral medication depends on the viral cause, highlighting the importance of accurate diagnosis in guiding treatment 1.
Monitoring and Specialist Consultation
It is essential to monitor liver function tests during treatment to assess the response to therapy and adjust the treatment plan as necessary. Severe cases of hyperbilirubinemia or those with complex underlying conditions may require consultation with a hepatology specialist for optimal management 1. Given the most recent and highest quality evidence available, the treatment should always prioritize addressing the underlying cause of hyperbilirubinemia, as hyperbilirubinemia itself is typically a symptom rather than a disease entity, and management strategies should be tailored accordingly 1.

From the Research
Medications for Hyperbilirubinemia in Adults
- Rifampicin has been shown to be effective in treating severe hyperbilirubinemia, particularly in patients with persistent hyperbilirubinemia 2.
- Phenobarbital has been found to improve hepatic clearance of ursodeoxycholic acid and reduce serum bilirubin levels in patients with Gilbert's syndrome 3.
- Ursodeoxycholic acid may be used to treat certain types of hyperbilirubinemia, such as those associated with impaired hepatic transport of bile acids 3.
- Antiviral medications may cause hyperbilirubinemia as a side effect, and modification of drug choice or dose may be required in cases of liver injury or hemolysis 4.
- Ceftriaxone, an antibiotic, has been associated with reversible biliary sludge, pseudolithiasis, and cholestasis, and may cause marked direct hyperbilirubinemia in some patients, particularly those with sickle cell disease 5.
Treatment Approaches
- The choice of medication for hyperbilirubinemia depends on the underlying cause of the condition and the presence of any underlying liver disease or other medical conditions 2, 3, 4, 5.
- In some cases, elimination of the offending agent, such as a medication that is causing hyperbilirubinemia, may be necessary to improve the condition 5.
- A careful history and physical examination, followed by directed imaging of the biliary tree and liver, are important steps in evaluating patients with jaundice and hyperbilirubinemia 6.
