1. What CitraFleet oral solution is and what it is used for

You are taking CitraFleet oral solution to clean your bowel (also known as intestine and colon) before undergoing any diagnostic procedure requiring a clean intestine, for example, a colonoscopy (a procedure that examines the inside of the bowel using a long flexible instrument inserted by the doctor through the anus) or radiographic examination. CitraFleet is an oral solution with a pleasant taste and smell resembling pomegranate. It contains two types of laxatives mixed in each bottle, which, when consumed, flush and clean the bowel. It is important that the bowel is empty and clean so that the doctor or surgeon can see clearly.
CitraFleet oral solution is indicated in adults (including elderly patients) aged 18 years and older.

2. What you should know before taking CitraFleet oral solution

Do not take CitraFleet oral solution if:

  • you are allergic to sodium picosulfate, magnesium oxide, citric acid, or any of the other ingredients of this medicine (listed in section 6).
  • you have congestive heart failure (the heart is unable to pump blood adequately throughout the body).
  • you have a condition called gastric retention (the stomach does not empty properly).
  • you have a stomach ulcer (sometimes called gastric or duodenal ulcer).
  • you have intestinal obstruction or impaired normal intestinal motility (sometimes called ileus).
  • your doctor has told you that you have a damaged intestinal wall (also known as toxic colitis).
  • you have an enlarged colon (also known as toxic megacolon).
  • you have recently become ill or feel unwell (nausea or vomiting).
  • you are very thirsty or think you may be severely dehydrated.
  • your doctor has told you that you have abdominal swelling due to fluid retention (called ascites).
  • you have recently undergone abdominal surgery, e.g. for appendicitis.
  • you may have a perforated/damaged or blocked intestine (intestinal perforation or obstruction).
  • your doctor has told you that you have active inflammatory bowel disease (e.g. Crohn’s disease or ulcerative colitis).
  • your doctor has told you that you have damaged muscles, causing their contents to be released into the blood (rhabdomyolysis).
  • you have severe kidney problems or your doctor has told you that you have too much magnesium in your blood (hypermagnesemia).

Warnings and precautions
Talk to your doctor or pharmacist before taking CitraFleet oral solution if:

  • you have recently undergone intestinal surgery.
  • you have kidney or heart problems.
  • you have fluid and/or electrolyte imbalance (sodium or potassium), or you are taking medicines that may affect your body’s fluid and/or electrolyte balance (sodium or potassium), such as diuretics, corticosteroids, or lithium.
  • you have epilepsy or a history of seizures.
  • you have low blood pressure (hypotension).
  • you are thirsty or think you may be mildly or moderately dehydrated.
  • you are elderly or physically frail.
  • you have previously had low levels of sodium or potassium in your blood (also known as hyponatremia or hypokalemia).
  • you experience severe or persistent abdominal pain and/or rectal bleeding after treatment with CitraFleet, inform your doctor. This is because CitraFleet has been rarely associated with intestinal inflammation (colitis).

Please keep in mind that after taking CitraFleet oral solution, you will have frequent loose stools. You must drink plenty of clear fluids (see section 3) to replace lost fluids and salts. Otherwise, you may become dehydrated and develop low blood pressure, which could cause you to faint.

Be prepared for frequent bowel movements with loose stools after taking each dose of CitraFleet oral solution. This is normal and indicates that the medicine is working. You should ensure easy access to a toilet until these effects subside.

The treatment can be administered in one of the following ways:

  • One bottle the evening before the procedure and the second bottle on the morning of the procedure.
  • One bottle in the afternoon and the second bottle in the evening before the procedure. This schedule is recommended when the procedure is scheduled for early morning, or
  • Both bottles on the morning of the procedure. This schedule is suitable only when the procedure is scheduled for the afternoon/evening.

The interval between the two bottles must be at least 5 hours.
Do not further dilute the product by drinking fluids immediately after taking each bottle.

Clear broth and/or balanced electrolyte solutions are recommended to prevent dehydration. Drinking water alone is not advised.
After taking the second bottle and consuming 1.5–2 litres of fluids, do not eat or drink anything else for at least 2 hours before the procedure, or as directed by your doctor.
