minor Known Drug Interaction
Ion Exchange Resins: Staggering the dosage of hydrochlorothiazide and ion exchange resins (e.g., cholestyramine, colestipol) such that hydrochlorothiazide is administered at least 4 hours before or 4 to 6 hours after the administration of resins, would potentially minimize the interaction [see Clinical Pharmacology (12.3)] . ( 7 ) Cholestyramine and Colestipol: Reduced absorption of thiazides.
Exforge
Colestid
Exforge HCT is a combination medicine used to treat high blood pressure. It contains amlodipine, valsartan, and hydrochlorothiazide to help lower your blood pressure.
Colestipol is a drug that helps lower cholesterol levels in your blood. It works by binding to bile acids in your intestine, which helps your body get rid of cholesterol.
Exforge HCT is used to treat high blood pressure. Lowering blood pressure reduces the risk of heart problems and strokes. It is for people who need more than one medicine to control their blood pressure. It is not for the initial treatment of high blood pressure.
Colestipol is used along with a healthy diet to lower high cholesterol levels, specifically LDL-C ('bad' cholesterol). It is for people who haven't been able to lower their cholesterol enough with diet alone. Lowering cholesterol can help prevent heart disease and stroke.
This medicine works in three ways to lower blood pressure. Amlodipine relaxes your blood vessels. Valsartan blocks a substance that tightens blood vessels. Hydrochlorothiazide helps your body get rid of extra salt and water.
Colestipol is a bile acid sequestrant. It binds to bile acids in your intestines. This helps your body get rid of cholesterol, which lowers the amount of cholesterol in your blood.

amlodipine/valsartan is classified in the CCB / ARB Combination drug class, while colestipol sits within the Bile Acid Sequestrant class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, amlodipine/valsartan has 47 submissions while colestipol has 1,050. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to this drug can bind to your blood pressure medicine in your digestive tract, preventing the medicine from working correctly.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for amlodipine/valsartan or colestipol.
