From the Guidelines

Cyproheptadine is not recommended as a standard treatment for hepatitis, as it has no established role in treating viral, alcoholic, or autoimmune hepatitis. The primary use of cyproheptadine is for allergic conditions and as an appetite stimulant, with antiserotonergic properties. For patients with hepatitis, standard treatments depend on the specific type:

  • antiviral medications for viral hepatitis (such as entecavir or tenofovir for hepatitis B, or direct-acting antivirals for hepatitis C) 1
  • abstinence from alcohol for alcoholic hepatitis
  • or immunosuppressants for autoimmune hepatitis. Some studies have explored the use of various medications for cholestatic pruritus, including cholestyramine, rifampicin, and sertraline, but cyproheptadine is not mentioned as a recommended treatment option 1. Using cyproheptadine for hepatitis outside of clinical trials is not supported by evidence and could potentially interfere with established treatments or worsen outcomes. Patients with hepatitis should work with hepatologists or gastroenterologists to develop appropriate treatment plans based on their specific diagnosis, viral load, liver function tests, and overall health status. Key considerations in managing hepatitis include:
  • Identifying the underlying cause of hepatitis
  • Selecting the most appropriate treatment based on the specific type of hepatitis
  • Monitoring liver function and adjusting treatment as needed
  • Addressing any related symptoms, such as pruritus, with evidence-based treatments. In the context of cholestatic pruritus, treatments like cholestyramine and rifampicin have a stronger evidence base 1, and should be prioritized over unproven agents like cyproheptadine.

From the Research

Cyproheptidine in Hepatitis

  • There is no direct evidence in the provided studies regarding the use of Cyproheptidine in hepatitis.
  • However, the studies discuss the management of pruritus in chronic cholestatic liver diseases, which can be associated with hepatitis.
  • Some studies mention the use of antihistamines, such as 2, but they are noted to be ineffective in hepatic itch, as stated in 3.
  • Other treatments for pruritus in liver diseases are discussed, including cholestyramine, rifampicin, naltrexone, and sertraline, as mentioned in 3.
  • The pathogenesis and therapy of pruritus in liver diseases are reviewed in 4, but Cyproheptidine is not mentioned.
  • The studies focus on the management of pruritus in chronic cholestatic liver diseases, such as primary biliary cholangitis, and do not provide information on the use of Cyproheptidine in hepatitis, as seen in 5, 6, 2.
