Summary
Cholestyramine resin is used to lower high cholesterol levels, which is a risk factor for heart disease. It also helps relieve itching caused by liver disease, which occurs when bile acids build up in the body. This medication is often combined with diet and lifestyle changes to improve cholesterol levels and manage symptoms.
Cholestyramine resin works by binding bile acids in the intestine, which are made from cholesterol and help digest fats. This binding prevents reabsorption, forcing the liver to use more cholesterol to make new bile acids, thereby lowering cholesterol levels in the blood and reducing heart disease risk.
The usual starting dose for adults is 4 grams once or twice daily. It is important to mix the powder with water or another liquid before taking it. Do not take it dry. The maximum recommended dose is 24 grams per day. Always follow your doctor's specific dosing instructions.
Common adverse effects of cholestyramine resin include constipation, bloating, and gas, which are unwanted reactions to the medication. These occur in a small percentage of users. More serious effects, like severe constipation or intestinal blockage, are rare but require immediate medical attention.
Cholestyramine resin can interfere with the absorption of other medications, so take it at least 1 hour before or 4 to 6 hours after other drugs. It may cause constipation, so drink plenty of water. It should not be used if you have a complete biliary obstruction, which is a blockage in the bile duct.
Indications and Purpose
How does cholestyramine resin work?
Cholestyramine resin works by binding bile acids in the intestine. Bile acids, which are made from cholesterol, help digest fats. When cholestyramine resin binds these acids, it prevents them from being reabsorbed into the body. This forces the liver to use more cholesterol to make new bile acids, which lowers cholesterol levels in the blood. Think of it like a sponge soaking up excess bile acids, helping to remove cholesterol from your system. This process helps reduce the risk of heart disease.

Cholestyramine resin is often used alongside diet and lifestyle changes to improve cholesterol levels. It may also be used to treat itching caused by liver disease. Your doctor can provide more information on how this medication can benefit your specific condition.
