Cholestyramine (Questran)

Cholestyramine (Questran) might decrease how much tiratricol the body absorbs. By decreasing how much tiratricol the body absorbs, cholestyramine (Questran) might decrease the effectiveness of tiratricol supplements. To avoid this interaction, take tiratricol at least one hour before or four hours after taking cholestyramine.
