What Is Cholestyramine 4g?
Cholestyramine is a prescription powder that belongs to a class of medications called bile acid sequestrants. It binds bile acids in the intestine, prompting the liver to use cholesterol to make more bile acids, which helps lower LDL ("bad") cholesterol. It is also used to relieve itching caused by partial biliary obstruction, a condition where bile acids build up in the body. Cholestyramine is not absorbed into the bloodstream and is taken by mixing the powder with water or another liquid.
