Cholestabyl , Colestid, Lestid
Classifications: antilipemic; bile acid sequestrant; Therapeutic: cholesterol-lowering agent; bile acid sequestrant
Pregnancy Category: C
1 g tablets; 5 g powder for suspension
Insoluble chloride salt of a basic anion exchange resin with high molecular weight, which adsorbs and combines with intestinal
bile acids in exchange for chloride ions to form an insoluble, nonabsorbable complex that is excreted in the feces.
Reduces circulating cholesterol and increases serum LDL removal rate. Serum triglycerides are not affected or are minimally
Pruritus associated with partial biliary obstruction; biliary cirrhosis; also as adjunct to diet therapy of patient with
primary hypercholesterolemia (type IIa hyperlipoproteinemia) or with coronary artery disease unresponsive to diet or other
Digitoxin overdose and hyperoxaluria and to control postoperative diarrhea caused by excess bile acids in colon.
Complete biliary obstruction, biliary cirrhosis; hypersensitivity to bile acid sequestrants; renal disease; pregnancy (category
C). Safe use in children not established.
Hemorrhoids; bleeding disorders; malabsorption states; GI motility disorders, dysphagia; older adult.
Route & Dosage
Adult: PO 1530 g/d in 24 doses a.c. and h.s., or 12 tabs 12 times/d
Adult: PO 10 g followed by 5 g q68h as needed
- Give 30 min before a meal when ordered a.c.
- Ensure that tablets are not chewed or crushed. They must be swallowed whole.
- Always mix granule form with liquids, juices, soups, cereals, or pulpy fruits. Add powder to at least 90 mL fluid. When
carbonated drink is used, slowly stir in a large glass because excess foaming may occur. Rinse glass with small amount extra
fluid to be sure all the drug is taken.
- Drugs given concomitantly should be scheduled at least 1 h before or 4 h after ingestion of colestipol to reduce interference
with their absorption (see drug interactions).
- Store at 15°30° C (59°86° F) in tightly closed container unless otherwise instructed.
Adverse Effects (≥1%) Body as a Whole:
Joint and muscle pain, arthritis
, shortness of breath. GI: Constipation,
abdominal pain or distention, belching, flatulence, nausea, vomiting, diarrhea
Transient increases in liver enzyme
phosphorus and chloride; decreases in serum
sodium and potassium. Skin:
Because it decreases the absorption from the GI tract of oral anticoagulants
, digoxin, tetracyclines
, phenobarbital, thyroid hormones
, thiazide diuretics
, iron salts
, fat-soluble vitamins
(A, D, E, K), administer cholestyramine 4 h before or 2 h after these drugs. Can bind and affect absorption of any drug.
Not absorbed from GI tract. Elimination:
In feces as insoluble complex.
Assessment & Drug Effects
- Watch for changes in bowel elimination pattern. Constipation should not be allowed to persist without medical attention.
- Lab test: Monitor serum sodium and potassium levels. Monitor for and report S&S of hyponatremia and hypokalemia (see Appendix
Patient & Family Education
- Do not change the times for taking each drug, nor omit or increase doses. Any change in established regimens should be approved
by the physician. It is important to keep to established regimens for colestipol and other drugs.
- If receiving prolonged therapy, report unusual bleeding (vitamin K deficiency). Colestipol prevents absorption of FAT-SOLUBLE VITAMINS (A, D, E, K).
- Do not use OTC drugs unless physician has given approval.
- Check with physician regarding permitted amount of alcohol intake.
