CitraFleet – Citric acid and Magnesium oxide uses, dose and side effects


Powder for oral solution in sachet Sodium picosulphate
, light magnesium oxide and citric acid

1. What CitraFleet is and what it is used for

You take CitraFleet to clean the intestines (small and large intestine) before undergoing a diagnostic examination that requires a clean bowel, such as a colonoscopy (an examination that looks at the inside of the intestine using a long, flexible instrument that the doctor inserts through the anal opening) or X-ray examination. CitraFleet is a powder that smells and tastes like lemon. It contains two types of laxatives in each sachet. When the powder is dissolved in water and drunk, it rinses out and cleanses the intestines. It is important to have an empty and cleansed bowel so that the doctor or surgeon can see clearly.

CitraFleet is intended for use by adults (including the elderly) who are 18 years of age or older.

Sodium picosulphate, light magnesium oxide, and citric acid contained in CitraFleet may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions and always follow their instructions.
