Drug interactions
Moderate drug interactions
Moderate:
cholestyramine estrone
Applies to: cholestyramine and estrone
Cholestyramine may interfere with the absorption of estrone when these medications are taken at the same time. This may reduce the blood levels and effects of estrone.
What to do: To prevent or minimize the interaction, estrone should be taken at least 1 hour before or 4 to 6 hours after the cholestyramine dose.
Contact your doctor if your condition changes or your symptoms worsen during treatment with these medications.
It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Disease interactions
15 potential interactions Applies to: 15 conditions, including Vitamin D Deficiency, Constipation, Anemia, Hemorrhoids, and Vitamin A Deficiency.
Anemia
Moderate:
cholestyramine
Cholestyramine has a moderate potential interaction with Anemia.
Bile acid sequestrants may interfere with the absorption of folic acid and fat soluble vitamins such as A, D, and K. Chronic use of bile acid sequestrants may cause increased bleeding tendency due to hypoprothrombinemia associated with vitamin K deficiency. Anemia may also occur due to reduced serum or red blood cell folate. Supplementation with oral vitamins and/or folate should be considered during prolonged therapy with bile acid sequestrants, particularly in patients with preexisting vitamin and/or folate deficiencies, anemia, or a bleeding diathesis.
Biliary Obstruction
Major:
cholestyramine
Cholestyramine has a major potential interaction with Biliary Obstruction.
The use of bile acid sequestrants is contraindicated in patients with complete biliary obstruction where bile is not secreted into the intestine. These agents adsorb and combine with bile acids in the intestine to form an insoluble complex that is excreted in the feces, resulting in partial removal of bile acids from the enterohepatic circulation. Bile acid sequestrants are ineffective if bile does not reach the intestine.
Coagulation Defects and Disorders
Moderate:
cholestyramine
Cholestyramine has a moderate potential interaction with Coagulation Defects and Disorders.
Bile acid sequestrants may interfere with the absorption of folic acid and fat soluble vitamins such as A, D, and K. Chronic use of bile acid sequestrants may cause increased bleeding tendency due to hypoprothrombinemia associated with vitamin K deficiency. Anemia may also occur due to reduced serum or red blood cell folate. Supplementation with oral vitamins and/or folate should be considered during prolonged therapy with bile acid sequestrants, particularly in patients with preexisting vitamin and/or folate deficiencies, anemia, or a bleeding diathesis.
Constipation
Moderate:
cholestyramine
Cholestyramine has a moderate potential interaction with Constipation.
The use of bile acid sequestrants may produce or worsen preexisting constipation. Constipation associated with these agents may aggravate hemorrhoids. Therapy with bile acid sequestrants should be administered cautiously in patients with preexisting constipation, hemorrhoids, or symptomatic coronary artery disease. The dosage should be increased very gradually according to manufacturer guidelines to minimize the risk of fecal impaction, and patients should be encouraged to increase fluid and fiber intake. Occasional use of a stool softener may also be indicated. If constipation worsens or develops during therapy, or the desired therapeutic response is not achieved at the maximum recommended daily dosage, combination therapy or an alternative agent should be considered.
Dehydration
Moderate:
cholestyramine
Cholestyramine has a moderate potential interaction with Dehydration.
Bile acid sequestrants are chloride forms of anion exchange resins and may produce hyperchloremic acidosis with chronic use. Therapy with bile acid sequestrants should be administered cautiously in patients who may be particularly susceptible, including children or smaller patients and patients with renal impairment or volume depletion.
Folic Acid/Cyanocobalamin Deficiency
Moderate:
cholestyramine
Cholestyramine has a moderate potential interaction with Folic Acid/Cyanocobalamin Deficiency.
Bile acid sequestrants may interfere with the absorption of folic acid and fat soluble vitamins such as A, D, and K. Chronic use of bile acid sequestrants may cause increased bleeding tendency due to hypoprothrombinemia associated with vitamin K deficiency. Anemia may also occur due to reduced serum or red blood cell folate. Supplementation with oral vitamins and/or folate should be considered during prolonged therapy with bile acid sequestrants, particularly in patients with preexisting vitamin and/or folate deficiencies, anemia, or a bleeding diathesis.
Hemorrhoids
Moderate:
cholestyramine
Cholestyramine has a moderate potential interaction with Hemorrhoids.
The use of bile acid sequestrants may produce or worsen preexisting constipation. Constipation associated with these agents may aggravate hemorrhoids. Therapy with bile acid sequestrants should be administered cautiously in patients with preexisting constipation, hemorrhoids, or symptomatic coronary artery disease. The dosage should be increased very gradually according to manufacturer guidelines to minimize the risk of fecal impaction, and patients should be encouraged to increase fluid and fiber intake. Occasional use of a stool softener may also be indicated. If constipation worsens or develops during therapy, or the desired therapeutic response is not achieved at the maximum recommended daily dosage, combination therapy or an alternative agent should be considered.
Ischemic Heart Disease
Moderate:
cholestyramine
Cholestyramine has a moderate potential interaction with Ischemic Heart Disease.
The use of bile acid sequestrants may produce or worsen preexisting constipation. Constipation associated with these agents may aggravate hemorrhoids. Therapy with bile acid sequestrants should be administered cautiously in patients with preexisting constipation, hemorrhoids, or symptomatic coronary artery disease. The dosage should be increased very gradually according to manufacturer guidelines to minimize the risk of fecal impaction, and patients should be encouraged to increase fluid and fiber intake. Occasional use of a stool softener may also be indicated. If constipation worsens or develops during therapy, or the desired therapeutic response is not achieved at the maximum recommended daily dosage, combination therapy or an alternative agent should be considered.
Phenylketonuria
