Frequently asked questions about cholestyramine

Medically reviewed by:
Jessica Swirble, PharmD

Cholestyramine is a prescription medication used for various purposes, including lowering cholesterol levels and managing certain gastrointestinal conditions. It belongs to the class of drugs known as bile acid sequestrants. Cholestyramine binds to bile acids in the digestive tract, preventing them from being reabsorbed into the bloodstream. This leads to a reduction in cholesterol levels and can help manage specific gastrointestinal issues.

Cholestyramine is available under the brand names Prevalite and Questran, and a generic version is also available.

This medication can only be obtained with a prescription, meaning you must have a written prescription from a licensed healthcare provider to purchase it.

Cholestyramine is prescribed for several purposes, including:

  • Lowering high cholesterol levels in individuals with hyperlipidemia (high blood cholesterol)
  • Managing pruritus (itching) associated with partial biliary obstruction
  • Relieving diarrhea and other gastrointestinal symptoms in individuals with chronic diarrhea associated with bile acid malabsorption
  • Treating diarrhea caused by certain gastrointestinal conditions, such as irritable bowel syndrome with diarrhea (IBS-D)

Cholestyramine binds to bile acids in the digestive tract, forming a complex that cannot be absorbed into the bloodstream. Bile acids are essential for digestion and are synthesized from cholesterol in the liver. By removing bile acids from circulation, cholestyramine prompts the liver to use more cholesterol to produce additional bile acids, ultimately reducing the overall cholesterol levels in the blood.

In individuals with gastrointestinal conditions, cholestyramine can help reduce diarrhea by binding to bile acids that would otherwise contribute to bowel irritation.

The use of cholestyramine may lead to adverse side effects.

Mild side effects associated with cholestyramine may include:

  • Constipation
  • Abdominal discomfort or pain
  • Bloating
  • Gas
  • Nausea
  • Vomiting
  • Heartburn

More severe side effects are rare but may include:

  • Allergic reactions (such as rash, itching, swelling, severe dizziness, or difficulty breathing)
  • Severe stomach pain or cramps
  • Increased bleeding time (especially in individuals taking anticoagulants like warfarin)
  • Unexplained bleeding or bruising
  • Changes in liver function (elevated liver enzymes)

If you experience any of these side effects or have concerns about them, consult your healthcare provider.

Before starting treatment with cholestyramine, inform your healthcare provider about any existing medical conditions, allergies, or other medications you are taking. This includes prescription drugs, over-the-counter medications, and dietary supplements, as they may interact with cholestyramine.

Specifically, tell your healthcare provider if you have a history of:

  • Heart disease (especially angina)
  • Liver disease
  • Gallbladder disease
  • Stomach disease
  • Hemorrhoids
  • Phenylketonuria
  • Allergies to medications or foods

If you are pregnant, planning to become pregnant, or breastfeeding, consult your healthcare provider before using cholestyramine to assess potential risks and benefits.

The dosing of cholestyramine may vary depending on the individual and the medical condition being treated. Your healthcare provider will determine the appropriate dosage for your situation.

Cholestyramine is typically taken as a powder that should be mixed with water or other non-carbonated liquids. It is important to follow the instructions provided by your healthcare provider for mixing and taking the medication.

Do not exceed the recommended dosage or change the dosing regimen without consulting your healthcare provider.

Take the medication exactly as prescribed, and inform your doctor if you begin to experience any side effects while taking the medication.

If you miss a dose, take it as soon as possible. If it's nearly time for your next dose, skip the missed dose and take your regularly scheduled amount. Do not take a double dose of cholestyramine.

Store cholestyramine in its original container at room temperature, away from excessive heat or moisture. Keep the medication out of the reach of children and ensure that the container is tightly closed.

Cholestyramine is available by prescription only. A licensed healthcare provider must authorize the use of this drug.
