How does this medication work? What will it do for me?
Cholestyramine resin belongs to the class of medications known as bile acid sequestrants. When used along with changes to diet and exercise, this medication helps to reduce cholesterol levels in the blood. It works by binding to cholesterol-like substances called bile acids in the intestines and preventing them from being absorbed into the body.
Cholestyramine resin may be used for symptomatic control of bile-induced diarrhea due to short bowel syndrome and may also be used to relieve itchiness associated with partial blockage of bile ducts.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
How should I use this medication?
The recommended dose of cholestyramine resin is 4 g (1 packet) 1 to 6 times daily depending on circumstances.
The powder must be mixed with water (120 mL to 180 mL for the regular powder and 60 mL to 90 mL for the "light" powder) or other fluids (milk, fruit juice, or other non-carbonated beverage). It may also be mixed with watery soups or pulpy fruits with a high moisture, content such as applesauce or crushed pineapple.
Other medications should be taken at least one hour before or 4 to 6 hours after cholestyramine resin. Cholestyramine should never be taken in its dry form. The colour of cholestyramine resin may vary somewhat from batch to batch but this does not affect the performance of the medication.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Bleeding tendency: Long-term use of cholestyramine resin may increase bleeding tendency due to vitamin K deficiency.
Constipation: Cholestyramine resin may produce or worsen constipation. Fecal impaction (a large mass of stool that may be lodged in the colon) and worsening of hemorrhoids may occur.
Pregnancy: Since cholestyramine resin is not absorbed by the body, it is not expected to harm the baby during pregnancy when taken in recommended doses. However, this medication may reduce the absorption of fat-soluble vitamins (vitamins A, D, E, and K), which should be taken into account when planning for vitamin intake during pregnancy.
Breast-feeding: Breast-feeding mothers should exercise caution when taking cholestyramine resin. The possible lack of proper vitamin absorption may have an effect on breast-feeding infants.
Children: The effects of this medication on children are not known. Experts recommend, however, that treatment with this medication be considered for children 10 years or older who have tried diet therapy but still have unacceptably high serum cholesterol levels. In certain situations where a young child has extremely high serum cholesterol levels, treatment with medication may even start before 10 years of age. If a child starts treatment with this medication, a carefully planned diet should be followed in order to obtain best results.
Seniors: People over 60 years of age may be more likely to experience gastrointestinal (stomach and intestines) side effects.

- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
