Treatment of Primary Sclerosing Cholangitis with Pruritus and No Dominant Biliary Stricture
A substantial proportion of patients with primary sclerosing cholangitis (PSC) experience pruritus — persistent, sometimes severe itch. When no dominant or relevant biliary stricture or obstruction is identified, the management of this symptom follows a structured, stepwise protocol.
Clinical Scenario
Pruritus affects 30%–60% of patients with PSC and can be severe and disabling. In the absence of a dominant or relevant biliary stricture, treatment escalates through a defined sequence of interventions — beginning with general measures and advancing through successive pharmacological options when symptom control is insufficient.
Treatment Approach
When initial general comfort strategies do not provide adequate relief, a bile acid sequestrant taken before meals is the recommended first pharmacological step in the sequence.
The complete stepwise regimen — including all options, sequencing, and escalation criteria — is available via the full protocol below.

- Many patients with PSC (30%–60%) suffer from pruritus, or itch, which can be severe and disabling.
- In the absence of a relevant stricture, a stepwise therapeutic approach should be followed starting with heat avoidance, emollients, and/or antihistamines, followed if necessary by first-line (cholestyramine), second-line (sertraline, rifampin, and/or naltrexone), and third-line (phenobarbital, plasmapheresis, and/or phototherapy) therapy, with LT considered for continued refractory symptoms.
- If these measures are ineffective, bile acid sequestrants, such as cholestyramine (4–16 mg/day), taken approximately 20 min before a meal for optimal effect, should be used.
