What is colestipol, and what is it used for?
Colestipol is a bile-acid sequestrant medication. It binds bile acids in the intestines so they can be removed from the body. Clinicians use colestipol primarily to help lower cholesterol levels (particularly LDL, often described as “bad cholesterol”). It can also be used for certain bile-acid–related diarrhea conditions, depending on the patient and prescribing decision.
How does colestipol compare with other bile-acid sequestrants?
Colestipol is in the same drug class as other bile-acid sequestrants such as cholestyramine and colesevelam. The main practical differences are dosing form and dosing schedule, which can affect adherence. If you’re choosing among them, prescribers often weigh how often the patient must take it, tolerability (especially gastrointestinal effects), and the patient’s other medications.
What side effects are patients most likely to notice?
Common issues with bile-acid sequestrants include gastrointestinal side effects such as constipation, bloating, gas, nausea, and stomach discomfort. Because they bind bile acids, they can also interfere with absorption of certain medications and fat-soluble vitamins in some patients, especially if dosing is not separated from other drugs.
How should colestipol be taken to avoid drug interactions?
Colestipol can reduce absorption of other medications by binding them in the gut. The usual approach is to separate doses of colestipol from other oral drugs by several hours (your pharmacist or prescriber can give the exact timing for your regimen). If you take thyroid medication, certain heart medications, or other long list of prescriptions, timing matters.
Is colestipol available as a brand or generics, and who makes it?
Colestipol is widely available as a medication product, and its availability often depends on the formulation (for example, tablet vs. granules) and local pharmacy supply.

What should you do if colestipol doesn’t lower cholesterol enough?
If cholesterol targets aren’t met, clinicians often adjust therapy by:
- improving adherence and dosing timing, since bile-acid sequestrants can be sensitive to missed doses,
- adding or switching to other lipid-lowering medicines (commonly statins and/or other cholesterol-lowering therapies, depending on your overall risk and lab results),
- reassessing secondary causes of high cholesterol.
What happens if you miss a dose?
If you miss a dose, you typically take it when you remember unless it’s close to the next scheduled dose. Because dosing schedules can vary by formulation and your clinician’s instructions, follow the specific directions on your prescription label.
What questions should patients ask their clinician?
Patients often ask about:
- whether colestipol is the best fit versus another bile-acid sequestrant,
- how to manage constipation or GI side effects,
- how to separate colestipol from their other medications,
- whether they need monitoring (lipid panels and sometimes vitamin/nutrient status if long-term use),
- when to expect cholesterol improvement after starting.
