Which non‑carbonated beverages, including tea, are acceptable to take with colesevelam?

Acceptable Beverages for Colesevelam Oral Suspension

Colesevelam oral suspension can be mixed with water, fruit juice, or diet soft drinks (non-carbonated), including tea if it is non-carbonated. 1

FDA-Approved Mixing Instructions

According to the FDA prescribing information, colesevelam powder for oral suspension should be prepared by:

• Emptying the entire contents of one packet into a glass or cup
• Adding 1 cup (8 ounces) of water, fruit juice, or diet soft drinks
• Stirring well and drinking 1

The key specification is that beverages should be non-carbonated. The 2022 ACC Expert Consensus explicitly states to "mix powder with 8 ounces of water, fruit juice, or soft drink" 2, while the 2017 guidelines specify "4-8 ounces of water, fruit juice, or soft drink" 3.

Tea as an Acceptable Option

Tea is acceptable as long as it is non-carbonated. While tea is not explicitly listed in the FDA label, it falls within the category of acceptable non-carbonated beverages. Research confirms that colesevelam powder can be prepared "in various beverages" with "pleasant taste from the inclusion of a low-calorie citrus flavoring" 4. The critical factor is avoiding carbonated beverages, not restricting specific types of non-carbonated drinks.

Important Administration Details

• Take with meals - this is mandatory per FDA guidance 1
• Do not take in dry form - must be mixed with liquid 1
• Use 8 ounces (1 cup) of liquid for proper mixing 1
• Stir well before drinking to ensure proper suspension 1

Clinical Considerations

The tablet formulation requires taking with "a meal and liquid" but does not specify beverage type 3. For the oral suspension, the beverage choice matters primarily for:

1. Proper dissolution and palatability - research shows the citrus-flavored powder mixes well and tastes pleasant in various beverages 4
2. Patient compliance - taste was rated as "very important" by 71.4% of patients for long-term adherence 5
3. Avoiding carbonation - which could interfere with proper mixing

The bottom line: Water, fruit juice, diet soft drinks, and non-carbonated tea are all acceptable mixing beverages for colesevelam oral suspension, as long as the medication is taken with a meal.
