How to Prepare Cholestyramine for Administration
Cholestyramine must never be taken in dry powder form—always mix it with at least 2-3 ounces of water or other non-carbonated beverages before ingesting. 1
Preparation Instructions
Basic Mixing Technique
- Place one single-dose pouch or one level scoopful (9 grams powder containing 4 grams anhydrous cholestyramine resin) in a glass or cup 1
- Add at least 2 to 3 ounces of water or other non-carbonated beverage of your choice 1
- Stir to a uniform consistency before drinking 1
Alternative Mixing Options
Beyond water, cholestyramine powder can be mixed with:
- Non-carbonated beverages (avoid carbonated drinks) 1
- Highly fluid soups 1
- Pulpy fruits with high moisture content such as applesauce or crushed pineapple 1
Dosing and Timing Considerations
Starting Dose
The recommended starting dose is one pouch or scoopful (4 grams anhydrous resin) once or twice daily 1. Product labeling specifically recommends starting at one 4-g dose daily and titrating to effect 2.
Timing Flexibility
While the suggested time of administration is at mealtime, this may be modified to avoid interference with absorption of other medications 1. The medication can be administered in 1 to 6 doses per day depending on patient tolerance and response 1.
Important Safety Considerations
Critical Warning
The dry powder should never be ingested without mixing with liquid first, as this poses a choking hazard and can cause esophageal obstruction 1.
Appearance Variation
The color of cholestyramine powder may vary somewhat from batch to batch, but this variation does not affect the product's performance 1. Patients should be counseled about this to avoid unnecessary concern.
Gradual Dose Titration
Gradual dose titration is recommended as a good practice statement to minimize gastrointestinal side effects (constipation, bloating, nausea) and improve compliance 2. In bile acid diarrhea studies, cholestyramine was typically started at 2-4 g/day and titrated based on response, with a maximum of 24 g/day 2.
