A resource I have trusted in the past provides the following information: “Gaining weight requires a schedule that balances the drug’s tendency to bind dietary fats and fat-soluble vitamins. Take cholestyramine either 1 hour before or 4–6 hours after consuming your main, calorie-rich meals.” This does not agree with other materials which seem to indicate having food with cholestyramine. However, those materials do not address a patient's desire to gain weight. Does anyone have experience with this situation, or can you recommend an authoritative site that addresses trying to gain weight while taking cholestyramine?
