Moviprep is a lemon flavoured laxative contained in four sachets. There are two large sachets ('sachet A') and two small sachets ('sachet B'). You need all these for one treatment. Moviprep is intended for adults to clean the bowel so that they are ready for examination. Moviprep works by emptying the contents of your bowels, so you should expect to have watery bowel movements. 2.
e Moviprep
Do not take Moviprep
If you need to thicken fluids in order to swallow them safely, Moviprep may counteract the effect of the thickener. When taking Moviprep you should continue to take plenty of fluids. The fluid content of Moviprep does not replace your regular liquid intake. Pregnancy, breast-feeding and fertility There are no data on the use of Moviprep during pregnancy or breast-feeding and it should only be used if considered essential by your doctor. If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Driving and using machines Moviprep does not affect your ability to drive or use machines. Moviprep contains sodium, potassium and a source of phenylalanine This medicine contains 8.4 g sodium (main component of cooking/table salt) per course of treatment. (A course of treatment consists of two litres of Moviprep). This is equivalent to 420% of the recommended maximum daily dietary intake of sodium for an adult. To be taken into consideration by patients on a controlled sodium diet. Only a proportion (up to 2.6 g per course treatment) of sodium is absorbed. This medicine contains 1.1 g potassium per course of treatment. (A course of treatment consists of two litres of Moviprep). To be taken into consideration by patients with reduced kidney function or patients on a controlled potassium diet. Contains a source of phenylalanine. May be harmful for people with phenylketonuria. 3.
Moviprep
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. The recommended dose is two litres of solution, which is made up as follows: This pack contains two clear bags each containing one pair of sachets: sachet A and sachet B. Each pair of sachets (A and B) is to be dissolved in water to make a one litre solution. This pack is therefore sufficient to make up two litres of Moviprep solution. Before you take Moviprep, please read carefully the following instructions. You need to know:
your examination: This course of treatment can be taken either as divided or single doses as described below: For procedures conducted when you are put to sleep (using general anaesthesia): 1.
Divided doses: one litre of Moviprep in the evening before and one litre of Moviprep in the early morning of the day of the examination. Ensure consumption of Moviprep as well as any other clear fluids has finished at least two hours before the start of the examination.
2.
Single dose: two litres of Moviprep in the evening before the examination or two litres of Moviprep in the morning of the examination. Ensure consumption of Moviprep as well as any other clear fluids has finished at least two hours before the start of the examination.
For procedures conducted without the need for putting you to sleep (without using general anaesthesia): 1.
Divided doses: one litre of Moviprep in the evening before and one litre of Moviprep in the early morning of the day of the examination. Ensure consumption of Moviprep as well as any other clear fluids has finished at least one hour before the start of the examination.
2.
Single dose: two litres of Moviprep in the evening before the examination or two litres of Moviprep in the morning of the examination. Ensure consumption of Moviprep has finished at least two hours before the start of the examination. Ensure consumption of any clear fluids has finished at least one hour before the examination.
Important: Do not take any solid food from when you start to take Moviprep until after the examination How to prepare Moviprep
How to drink Moviprep Drink the first litre of Moviprep solution over one to two hours. Try to drink a glassful every 10 – 15 minutes. When you are ready, make up and drink the second litre of Moviprep solution made up with the contents of the sachets A and B from the remaining bag. During the course of this treatment, you are recommended to drink a further one litre of clear 4
liquid to prevent you feeling very thirsty and becoming dehydrated. Water, clear soup, fruit juice (without pulp), soft drinks, tea or coffee (without milk) are all suitable. These drinks can be taken until two hours before the examination under general anaesthesia at the latest and until one hour before the examination without general anaesthesia at the latest. What you should expect to happen When you start drinking the Moviprep solution, it is important that you stay close to a toilet. At some point, you will start to experience watery bowel movements. This is quite normal and indicates that the Moviprep solution is working. The bowel movements will stop soon after you have finished drinking. If you follow these instructions, your bowel will be clear, and this will help you to have a successful examination. You should allow sufficient time after your last drink to travel to the colonoscopy unit. If you take more Moviprep than you should If you take more Moviprep than you should you may develop excessive diarrhoea, which can lead to dehydration. Take generous amounts of fluid, especially fruit juices. If you are worried contact your doctor or pharmacist. If you forget to take Moviprep If you forget to take Moviprep take the dose as soon as you realise you have not taken it. If this is several hours after the time when you should have taken it, contact your doctor or pharmacist for advice. When taking Moviprep as divided doses it is important that you complete your Moviprep preparation at least one hour before your examination (without use of general anaesthesia), or two hours before your examination (with use of general anaesthesia). When taking all your Moviprep on the morning of the examination as a single dose it is important that you complete your Moviprep preparation at least two hours before your examination. If you have any further questions on the use of this medicine, ask your doctor or pharmacist. 4.
Like all medicines Moviprep can cause side effects, although not everybody gets them. It is normal to get diarrhoea when you take Moviprep. Stop your intake and tell your doctor immediately if you have any of the following side effects:
If you do not have a bowel movement within 6 hours of taking Moviprep, stop the intake and contact your doctor immediately. Other side effects include: Very common side effects (may affect more than 1 in 10 people): Abdominal pain, abdominal distension, tiredness, feeling generally unwell, soreness of the anus, nausea and fever. Common side effects (may affect up to 1 in 10 people): Hunger, problems sleeping, dizziness, headache, vomiting, indigestion, thirst and chills. Uncommon side effects (may affect up to 1 in 100 people): Discomfort, difficulties swallowing, and changes to tests of liver function. The following side effects have sometimes been seen but it is not known how often they occur because the frequency cannot be estimated from the available data: flatulence (wind), temporary increase in blood pressure, irregular heart rhythm or palpitations, dehydration, retching (straining to vomit), oesophageal rupture due to vomiting, very low blood sodium levels that can cause convulsions (fits) and changes to the levels of salts in the blood such as decreased bicarbonate, increased or decreased calcium; increased or decreased chloride and decreased phosphate. Blood potassium and sodium levels could also decrease. These reactions usually only occur for the duration of the treatment. Should they persist, consult your doctor. Allergic reactions may cause a skin rash, itching, reddening of the skin or a nettle rash, swollen hands, feet or ankles, headaches, palpitations and shortness of breath.

Posology
Adults and Older People
A course of treatment consists of two litres of Moviprep. It is strongly recommended that one litre of clear liquid, which may include water, clear soup, fruit juice without pulp, soft drinks, tea and/or coffee without milk, is also taken during the course of treatment.
A litre of Moviprep consists of one 'sachet A' and one 'sachet B' dissolved together in water to make one litre of solution. The reconstituted solution should be drunk over a period of one to two hours. This process should be repeated with a second litre of Moviprep to complete this course.
This course of treatment can be taken either as divided or as single doses and timing is dependent on whether the clinical procedure is conducted with or without general anaesthesia as specified below:
For procedures conducted under general anaesthesia:
1. Divided doses: one litre of Moviprep in the evening before and one litre of Moviprep in the early morning of the day of the clinical procedure. Ensure consumption of Moviprep as well as any other clear fluids has finished at least two hours before the start of the clinical procedure.
2. Single dose: two litres of Moviprep in the evening before the clinical procedure or two litres of Moviprep in the morning of the clinical procedure. Ensure consumption of Moviprep as well as any other clear fluids has finished at least two hours before the start of the clinical procedure.
For procedures conducted without general anaesthesia:
1. Divided doses: one litre of Moviprep in the evening before and one litre of Moviprep in the early morning of the day of the clinical procedure. Ensure consumption of Moviprep as well as any other clear fluids has finished at least one hour before the start of the clinical procedure.
2. Single dose: two litres of Moviprep in the evening before the clinical procedure or two litres of Moviprep in the morning of the clinical procedure. Ensure consumption of Moviprep has finished at least two hours before the start of the clinical procedure. Ensure consumption of any clear fluids has finished at least one hour before the clinical procedure.
Patients should be advised to allow for appropriate time to travel to the colonoscopy unit.
No solid food should be taken from the start of the course of treatment until after the clinical procedure.
Paediatric population
Not recommended for use in children below 18 years of age, as Moviprep has not been studied in the paediatric population.
Method of administration
The route of administration is oral use. A litre of Moviprep consists of one sachet A and one sachet B dissolved together in water to make a one litre solution.
Precautions to be taken before handling or administering the medicinal product.
For instructions on reconstitution of the medicinal product before administration, see section 6.6.
Do not use in patients with known or suspected:
- hypersensitivity to the active substances or to any of the excipients listed in section 6.1
- gastrointestinal obstruction or perforation
- disorders of gastric emptying (e.g. gastroparesis)
- ileus
- phenylketonuria (due to presence of aspartame)
- glucose-6-phosphate dehydrogenase deficiency (due to presence of ascorbate)
- toxic megacolon, which complicates very severe inflammatory conditions of the intestinal tract including Crohn's disease and ulcerative colitis.
Do not use in unconscious patients
Diarrhoea is an expected effect resulting from the use of Moviprep.
Moviprep should be administered with caution to fragile patients in poor health or patients with serious clinical impairment such as:
- impaired gag reflex, or with a tendency to aspiration or regurgitation
- impaired consciousness
- severe renal insufficiency (creatinine clearance <30 mL/min)
- cardiac impairment (NYHA grade III or IV)
- those at risk of arrhythmia, for example those on treatment for cardiovascular disease or who have thyroid disease
- dehydration
- severe acute inflammatory bowel disease
The presence of dehydration should be corrected before the use of Moviprep.
The fluid content of Moviprep when re-constituted with water does not replace regular fluid intake and adequate fluid intake must be maintained.
Semi-conscious patients or patients prone to aspiration or regurgitation should be closely observed during administration, especially if this is via a nasogastric route.
In patients with swallowing problems, who need the addition of a thickener to solutions to enhance an appropriate intake, interactions should be considered, see section 4.5.
If patients develop any symptoms indicating arrhythmia or shifts of fluid/electrolytes (e.g. oedema, shortness of breath, increasing fatigue, cardiac failure), plasma electrolytes should be measured, ECG monitored and any abnormality treated appropriately.
In debilitated fragile patients, patients with poor health, those with clinically significant renal impairment, arrhythmia and those at risk of electrolyte imbalance, the physician should consider performing a baseline and post-treatment electrolyte, renal function test and ECG as appropriate.
Cases of seizures associated with use of macrogol 3350 with electrolytes for bowel preparation were observed in patients either with or without prior history of seizures. These cases were mostly associated with electrolyte abnormalities such as severe hyponatraemia (see section 4.8). Use caution when prescribing macrogol 3350 with electrolytes in patients with a history of seizures, at increased risk of seizure or at risk of electrolyte disturbance. In case of neurologic symptoms, fluid and electrolyte abnormalities should be corrected.
There have been rare reports of serious arrhythmias including atrial fibrillation associated with the use of ionic osmotic laxatives for bowel preparation. These occur predominantly in patients with underlying cardiac risk factors and electrolyte disturbance.
If patients experience symptoms such as severe bloating, abdominal distention, abdominal pain or any other reaction which makes it difficult to continue the preparation, they may slow down or temporarily stop consuming Moviprep and should consult their doctor.
Ischaemic colitis
Post-marketing cases of ischaemic colitis, including serious, have been reported in patients treated with macrogol for bowel preparation. Macrogol should be used with caution in patients with known risk factors for ischaemic colitis or in case of concomitant use of stimulant laxatives (such as bisacodyl or sodium picosulfate). Patients presenting with sudden abdominal pain, rectal bleeding or other symptoms of ischaemic colitis should be evaluated promptly.
Cases of oesophageal rupture (Boerhaave syndrome) associated with excessive vomiting after intake (see section 4.8) of macrogol 3350 with electrolytes for bowel preparation has been reported post-marketing, mostly in elderly patients. Advise patients to stop administration and seek immediate medical assistance if they experience incoercible vomiting and subsequent chest, neck, and abdominal pain, dysphagia, hematemesis or dyspnoea.
This medicinal product contains 363.2 mmol (8.4 g) sodium per course of treatment equivalent to 420% of the of the WHO recommended maximum daily intake of 2 g sodium for an adult. (A course of treatment consists of two litres of Moviprep). To be taken into consideration by patients on a controlled sodium diet. Only a proportion (up to 112.4 mmol (2.6 g) per course treatment) of sodium is absorbed.
This medicinal product contains 28.4 mmol (1.1 g) potassium per course of treatment. (A course of treatment consists of two litres of Moviprep). To be taken into consideration by patients with reduced kidney function or patients on a controlled potassium diet.
The medicinal product contains aspartame, which is a source of phenylalanine. This may be harmful for people with phenylketonuria.
The interaction of Moviprep with other medicinal products has not been studied. Theoretically, medicinal products taken orally (e.g. oral contraceptive pill) one hour before, during and one hour after Moviprep administration may be flushed from the gastrointestinal tract unabsorbed. The therapeutic effect of drugs with a narrow therapeutic index or short half-life may be particularly affected.
Moviprep may result in a potential interactive effect if used with starch-based food thickeners. The Macrogol ingredient counteracts the thickening effect of starch, effectively liquefying preparations that need to remain thick for people with swallowing problems.
Pregnancy
There are no data on the use of Moviprep during pregnancy.
The preparation should only be used during pregnancy if considered essential by the physician.
Breastfeeding
There are no data on the use of Moviprep during lactation.
The preparation should only be used during lactation if considered essential by the physician.
Fertility
There are no data on the effects of Moviprep on fertility.
Moviprep has no influence on the ability to drive and use machines.
Diarrhoea is an expected outcome of bowel preparation. Due to the nature of the intervention, undesirable effects occur in the majority of patients during the process of bowel preparation. Whilst these vary between preparations, nausea, vomiting, bloating, abdominal pain, anal irritation and sleep disturbance commonly occur in patients undergoing bowel preparation. Dehydration may occur as a result of diarrhoea and/or vomiting.
As with other macrogol containing products, allergic reactions including rash, urticaria, pruritus, dyspnoea, angioedema and anaphylaxis are a possibility.
Data from clinical studies are available in a population of 825 patients treated with Moviprep in which undesirable effect data were actively elicited. Additionally, adverse events reported in post marketing are included.
The frequency of adverse reactions to Moviprep is defined using the following convention:
Very common (≥ 1/10)
