How is pruritus in cholestasis commonly managed?

Pruritus in cholestasis comes from accumulation of bile acids that circulate and irritate sensations in the skin. The goal is to lower those circulating bile acids and improve bile flow, while also treating the underlying liver problem. Cholestyramine or other bile acid sequestrants are used first because they bind bile acids in the gut, interrupt their reabsorption, and reduce the amount returning to the liver. This lowers the pruritogenic burden and often provides relief. If itch persists, rifampin is a useful second-line option. It increases hepatic metabolism and clearance of bile acids, helping to reduce pruritus through enhanced elimination. In primary sclerosing cholangitis and some other cholestatic conditions, ursodeoxycholic acid can improve bile flow and decrease the bile acid pool, which may lessen pruritus as part of overall management of the cholestasis. A key part of management is addressing the underlying cause of cholestasis—relieving any obstruction, treating the inflammatory/degenerative process, and optimizing overall liver function—because stopping ongoing cholestasis reduces ongoing bile acid accumulation. Dietary changes or other approaches like a high-fat diet, immediate surgery, or increasing alcohol intake do not target the mechanism of pruritus in cholestasis and are not appropriate strategies for relief.
