What VistaPrep is and what it is used for

VistaPrep is used to empty the intestines prior to examination or surgery of the intestines. Use of this
medicine will cause diarrhoea and a watery stool, which rapidly empties the bowel.


Before you use VistaPrep

Do not use VistaPrep:

if you are allergic (hypersensitive) to macrogol 3350 or any of the other ingredients of
VistaPrep (see Section 6)
if you suffer from a blockage or obstruction in the intestines, or if you have a perforated
if you have a severe inflammation of the intestine or stomach, or if you have a severe
complication of acute colitis (toxic megacolon), or severely active ulcerative colitis
(hyperflorid colitis)
if you have problems emptying your stomach
if you have an acute or chronic ulcer in the stomach or intestines
if you often swallow the wrong way (aspiration) or belch (regurgitation), or if you have a
disturbed gag reflex
if you have an unstable blood pressure (haemodynamic instability)
if you have a general weakness
in children younger than 12 years, due to insufficient data on safety
in patients who are unconscious or semi-conscious.

Take special care with VistaPrep
Contact your doctor:
• if you are an elderly patient
• if you have reflux disease (‘heartburn’, reflux oesophagitis)
• if you have existing problems with your heart rhythm (SA block syndrome or sick sinus
• if your heart does not pump efficiently (a condition called ‘heart failure’), and you have
discomfort when performing light to moderate exercise or while resting
• if your kidneys and/or liver are not working efficiently (renal and hepatic insufficiency)
• if you have kidney failure or liver disease
• if you have severe dehydration
• if you have severe colitis, diverticulitis or chronic inflammatory bowel disease
In these cases VistaPrep can only be used under the supervision of a doctor who will check your
electrolytes and fluid balance.
This medicine contains 20 mmol potassium and 260 mmol sodium per 4 litres of VistaPrep solution.
This should be taken into consideration by patients on a controlled potassium or sodium diet. Patients
with problems of heart and blood vessels, other than unstable blood pressure or heart failure, can use
VistaPrep, but at a lower rate, as is described in section 3 ‘How to use VistaPrep’.
Using other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription. Oral medicines that have been taken several
hours prior to drinking VistaPrep solution may be washed out from the gastrointestinal tract and may
not be effective. This includes oral medication to treat diabetes and the contraceptive pill. Therefore,
additional contraceptive precautions are necessary. In case of any essential oral medication, ask your
doctor for an alternative.
Using VistaPrep with food and drink
Do not eat any solid food for at least 2 hours before you start drinking the VistaPrep solution. You may
drink coffee, juice, and clear liquids such as water and tea. You may eat solid food again after the
examination. In case surgery was performed, the doctor will inform you when you may eat again.
Pregnancy and breast-feeding
There is as yet very little experience with the use of VistaPrep during pregnancy and breast-feeding.
VistaPrep can only be used after careful consideration by a physician of the risks and benefits. If
you are pregnant or breastfeeding, contact your doctor or pharmacist before you take VistaPrep.


How to use VistaPrep

Always use VistaPrep exactly as your doctor has told you. If your doctor has not given any specific
advice, please follow the instructions in this leaflet. You should check with your doctor if you have
any questions.
The recommended dose for complete bowel cleansing is 4 litres of VistaPrep solution (this means 8
sachets of VistaPrep dissolved in 4 litres of water). Dissolve each sachet of VistaPrep (55.218 g) in
half a litre (500 ml) of lukewarm tap water. You can also use boiled water that has cooled. Wait until
the powder has completely dissolved before drinking the solution. The solution may be stored at
room temperature for no longer than 3 hours; it may be stored in the refrigerator for up to 48 hours.



Drink one glass (200 - 300 ml) of the solution every 10 minutes until you start passing clear fluids
or until you have finished drinking the full dosage of 4 litres of the solution. Start drinking the
solution at least 4 hours before the start of the examination or the surgery of the intestines.
Alternatively, you can drink the solution the evening before the procedure, or drink a portion of the
solution the evening before the procedure and the rest during the morning of the clinical procedure.
Patients with problems of heart and blood vessels, must not take more than a quarter of a litre per
hour. This means that taking the full dosage of 4 litres will take 16 hours. It is therefore better to start
drinking the solution 24 hours before the start of the procedure.
For a more agreeable taste, you may cool the solution in the refrigerator. Do not add anything to the
solution (such as sugar or flavouring), as this may have an influence on the effect of the solution. It is
also possible that gas mixtures will develop in the intestines caused by bacteria digesting such added
If you use more VistaPrep than you should
If you take considerably more VistaPrep than prescribed, this may lead to heavy diarrhoea. If this
happens, you should drink large amounts of water and consult your doctor.
If you forget to use VistaPrep
If you do not use the VistaPrep solution or if you use considerably less than instructed, your intestines
will not be emptied sufficiently. You must inform your doctor as the examination cannot be
performed as planned. Therefore, always follow the instructions of your doctor. If your doctor has
not given any instructions, please follow the instructions in this package leaflet. If you have any further
questions about the use of this product, ask your doctor or pharmacist.

In most cases these symptoms result from drinking a large volume within a short period of time. In
such cases, reduce the amount of VistaPrep you drink per hour or stop drinking temporarily until the
symptoms subside. Please consult your doctor.


If you have an allergic reaction to VistaPrep or if you develop symptoms such as swollen ankles,
shortness of breath, increasing fatigue, feeling very thirsty with a headache or cardiac failure, stop
