Cholestyramine (Questran) Tips from Pharmacists

  • Cholestyramine works best with a low-cholesterol diet and exercise plan.

  • Take cholestyramine before meals one to two times a day as prescribed.

  • Take other drugs at least 1 hour before or 4 hours after cholestyramine.

  • Use the scoop provided with the medicine to measure cholestyramine powder. Do not use a regular household spoon – this can result in incorrect dosing.

  • Do not sip on the suspension or keep in your mouth for long. This can lead to tooth discoloration and tooth decay.

  • Do not ingest cholestyramine (Questran) powder in the dry form. Always mix it with water, fruit juice, or crushed fruit.

  • Cholestyramine can cause constipation. Drink plenty of fluids and eat fiber-rich foods to lower the risk of this side effect.
