Recommended Starting Dose for Adults
The recommended starting adult dose for all QUESTRAN powdered products (QUESTRAN Powder and QUESTRAN LIGHT) is one packet or one level scoopful once or twice a day. The suggested time of administration is at mealtime but may be modified to avoid interference with absorption of other medications.
Maintenance Dose for All Questran Products
The recommended maintenance dose for all QUESTRAN powdered products is 2 to 4 packets or scoopfuls daily, which is equivalent to 8-16 grams of anhydrous cholestyramine resin. The maintenance dose should be divided into two administrations per day. It is advised to take the medication at mealtime to maximize its effectiveness while minimizing potential interactions with other medications. Always follow your healthcare provider’s instructions regarding the maintenance dose and dosing schedule to achieve optimal treatment outcomes.
Administration Guidance
Cholestyramine for oral suspension is usually taken once or twice per day but can be taken up to six times daily if prescribed by your healthcare provider. Mix the Questran powder with at least 2 to 6 ounces of water or another non-carbonated beverage. It is important to follow your doctor’s dosing instructions carefully to ensure the medication’s effectiveness.
Interactions and Considerations
Cholestyramine, as a bile acid sequestrant, forms complex with bile acids that is not absorbed in the intestine. It inhibits the enterohepatic reuptake of intestinal bile salts, leading to increased fecal loss of bile salt-bound LDL and reduction of serum cholesterol in patients with primary hypercholesterolemia. When taking cholestyramine, special attention is required to avoid potential interactions with fat-soluble vitamins A, D, E, and K due to its interference with fat absorption. The drug may exacerbate preexisting constipation, so it is crucial to initiate therapy at lower dosages for patients with a history of constipation. Individuals with coronary heart disease should be monitored closely for constipation symptoms. It is important to mix cholestyramine with fluids for ingestion and never consume it dry to prevent any adverse effects. Patients should be aware that some formulations of cholestyramine contain phenylalanine. Careful consideration is needed for chloride intake due to the large quantities of chloride ions released from the resin during prolonged use, potentially leading to hyperchloremic acidosis. To minimize the risk of drug interactions, it is advised to administer other medications at least one hour before or four to six hours after cholestyramine administration to prevent potential interference with absorption. Pregnancy Category A indicates that cholestyramine is generally acceptable with controlled studies showing no evidence of fetal risk. Excretion primarily occurs through the feces as an insoluble complex with bile acids.
Special Precautions and Recommendations
When taking Questran, precautions should be taken to avoid potential interactions with fat-soluble vitamins A, D, E, and K. Patients should be careful with long-term use, as it may lead to increased bleeding due to hypoprothrombinemia from vitamin K deficiency. It is crucial to initiate therapy cautiously in individuals with a history of constipation to prevent exacerbation of symptoms. Monitoring is essential for patients with symptomatic coronary heart disease to prevent complications related to constipation. Always mix Questran with fluids before ingestion. Patients should be aware that some formulations contain phenylalanine and may release large quantities of chloride ions, potentially leading to hyperchloremic acidosis. To minimize drug interactions, other medications should be administered at least one hour before or several hours after taking Questran. Pregnancy Category A indicates that Questran is generally safe for pregnant individuals based on controlled studies showing no fetal risk. It is crucial to follow healthcare provider instructions diligently for optimal treatment outcomes.
