Questran Powder Light is prescribed as an additional treatment to dietary measures for lowering high serum cholesterol in patients with primary hypercholesterolemia (elevated low-density lipoprotein [LDL] cholesterol) who do not achieve sufficient improvement through diet alone. 

Furthermore, Questran Powder Light is prescribed for alleviating itching linked to partial biliary obstruction. 

Classified as a bile acid-binding resin, Questran Powder Light works by eliminating bile acid from the body. For individuals with elevated cholesterol, this prompts the liver to produce additional bile acid, utilizing cholesterol from the blood and assisting in lowering cholesterol levels. 

Uses and Dosage 

Read the information provided on the packaging of Questran Powder Light before using it for the first time and with each prescription refill. If you have any questions, seek advice from your doctor or pharmacist. 

Questran Powder Light is a powdered medication in single-dose packets. It should be mixed with water or other fluids before consumption and should not be taken in its dry state. 

Typically, this medication is taken 1 to 2 times daily as prescribed by the doctor. 

To properly take a dose: 

  1. Open a packet and mix the powder in at least 2 to 6 ounces (60 to 180 milliliters) of liquid (water, milk, or fruit juice). 
  2. Stir thoroughly and consume immediately. 
  3. Rinse the glass with additional liquid and drink the rinse liquid to ensure you have taken the full dose. 

Alternatively, the powder can be mixed with thin soups (without heating the powder itself) or moist, pulpy fruits like applesauce or crushed pineapple. 

Avoid keeping the mixture in your mouth for an extended period to prevent potential damage to your teeth. Adhere to proper dental hygiene practices, including regular brushing and flossing. 

Regularly take Questran Powder Light at the same times each day to maximize its effectiveness. Keep taking it even if you feel good, as many individuals with high cholesterol do not experience noticeable symptoms.
