What is Cholestyramine?

Cholestyramine is the active ingredient found inside the brand-name product Questran Light. It belongs to the drug class called bile acid sequestrants; these types of drugs have an effect on bile acid. It comes in the form of a powder which is mixed with a liquid to create a mixture. Once it is administered, it is metabolized by bile acids with a half-life of only 1 hour and is then excreted through human waste (feces). We carry the brand-name product at My Drug Center, available to those with a valid prescription.


What is Cholestyramine used for?

Questran, the brand-name product containing Cholestyramine, is used for the treatment of high cholesterol in the blood stream. Lowering cholesterol levels that are too high can help reduce the risk of further complications, such as heart diseases and clogged arteries (atherosclerosis). It may also be used for the treatment of diarrhea as a result of bile acid malabsorption (a condition in which your intestines cannot absorb bile acids correctly).


How does Cholestyramine work?

Questran (Cholestyramine) works by binding bile acids in the intestines to eliminate them from the body through feces. When the body recognizes this loss of bile acid, it will begin to create more. The body creates bile acid by using cholesterol found in the blood stream. Once the body begins to create more bile acid, it will ultimately lower the total amount of cholesterol found in the blood. Additionally, Cholestyramine reduces the activity of bile acids in the large intestine which helps to reduce diarrhea when it is caused by bile acid malabsorption.


How long does it take Cholestyramine to start working for diarrhea?

This medication could take up to a month before the full effect is felt, but it will vary between each individual. Continue taking the medication as prescribed to get the best results.


How to take Cholestyramine?

Additionally, it may be mixed with brothy soup, crushed pineapple, or applesauce. It is typically mixed with at least 2-3 ounces of water (or whatever acceptable beverage or food you decide on).
