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.
