Cholestyramine in Thyroiditis: Efficacy and Recommendations

Adverse Effects and Considerations

• Common side effects of cholestyramine include abdominal bloating, pain, dyspepsia, nausea/vomiting, flatulence, borborygmi, abdominal distension, and constipation, with approximately 11% of patients finding it intolerable due to unpalatability or side effects 1
• Cholestyramine can impair the absorption of various medications, including UDCA, and should be administered separately from other drugs 2, 3

Important Considerations

• The American Gastroenterological Association recommends considering alternatives to cholestyramine, such as bezafibrate, for pruritus in cholestatic conditions, as newer evidence suggests it may be preferred 3, 4
• When using cholestyramine, it's essential to separate administration from other medications to avoid interaction, as recommended by the European Association for the Study of the Liver 2
