Summary
Colestyramine is used to lower high cholesterol levels, which is a risk factor for heart disease. It can also relieve itching caused by partial bile duct obstruction, which is a blockage in the tubes that carry bile from the liver.
Colestyramine works by binding to bile acids in the intestines, 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, thus lowering cholesterol levels.
Colestyramine is usually taken as a powder mixed with water or another liquid. The typical starting dose for adults is 4 grams once or twice daily, with a maximum of 24 grams per day. It's important to follow your doctor's instructions on how to take it.
Common side effects of colestyramine include constipation, bloating, and gas, which are unwanted reactions to the medication. These effects vary among individuals and are usually mild, but severe constipation can occur.
Colestyramine can interfere with the absorption of other medications and fat-soluble vitamins, which are vitamins that dissolve in fats. It should not be used if you have a complete bile duct blockage. Drink plenty of water to prevent constipation.

Colestyramine works by binding to bile acids in your intestines. Bile acids, which are made from cholesterol, help digest fats. When colestyramine binds to these acids, it prevents them from being reabsorbed into your body. This process forces your liver to use more cholesterol to make new bile acids, which lowers your cholesterol levels. Think of it like a sponge soaking up excess bile acids, helping to remove cholesterol from your body. This mechanism makes colestyramine effective in managing high cholesterol.
