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 recommended maintenance dose for all QUESTRAN powdered products is 2 to 4 packets or scoopfuls daily (8-16 grams anhydrous cholestyramine resin) divided into two doses. Four grams of anhydrous cholestyramine resin is contained in each measured dose of QUESTRAN as follows:
|QUESTRAN Powder||9 grams|
|QUESTRAN Light||5 grams|
It is recommended that increases in dose be gradual with periodic assessment of lipid/lipoprotein levels at intervals of not less than 4 weeks. The maximum recommended daily dose is six packets or scoopfuls of QUESTRAN (24 grams of anhydrous cholestyramine resin). The suggested time of administration is at mealtime but may be modified to avoid interference with absorption of other medications. Although the recommended dosing schedule is twice daily, QUESTRAN may be administered in 1–6 doses per day.
Preliminary evidence suggests that the lipid-lowering effects of QUESTRAN on total and LDL-cholesterol are enhanced when combined with a HMG-CoA reductase inhibitor, e.g., pravastatin, lovastatin, simvastatin, and fluvastatin. Additive effects on LDL-cholesterol are also seen with combined nicotinic acid/QUESTRAN therapy. See the Drug Interactions subsection of the PRECAUTIONS section for recommendations on administering concomitant therapy.
The color of QUESTRAN may vary somewhat from batch to batch but this variation does not affect the performance of the product.
