What Plenvu is used for
Plenvu is a type of medicine called a bowel preparation. It makes your bowels clean so that they are ready for examination or surgery. Plenvu works by emptying the contents of your bowels, so you should expect to have lots of watery bowel movements.
Plenvu is a dual flavoured laxative with two doses contained in three sachets. There is one sachet for Dose 1 (‘Dose 1 Sachet’) and two sachets for Dose 2 (‘Dose 2 Sachet A’ and ‘Dose 2 Sachet B’). You need to take all three sachets for one treatment. Dose 1 is mango flavour, Dose 2 is fruit punch flavour.
Plenvu is intended for adults (18 years of age and older), including the elderly, before any clinical procedure that needs a clean bowel.
Ask your doctor if you have any questions about why this medicine has been recommended for you.
Before you take Plenvu
When you must not take it
If you are in poor health or have a serious medical condition, you should be particularly aware of the possible side effects listed in the ‘Side Effects’ section. Contact your doctor, pharmacist or nurse if you are concerned.
Do not take Plenvu:
- if you are allergic (hypersensitive) to the active ingredients or any of the other ingredients of Plenvu (listed in ‘Product Description’)
- if you have a blockage in your bowel (bowel obstruction)

- if you experience problems with food and fluid emptying from your stomach (gastric retention)
- if you have paralysis of the gut (ileus)
- if you suffer from phenylketonuria. This is a hereditary inability of the body to use a particular amino acid. Plenvu contains a source of phenylalanine

Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking this medicine, seek medical advice.
Before you start to take it
To maintain good health, you should hydrate adequately before the use of any bowel preparation. If you develop significant vomiting, or signs of fluid loss (dehydration) tell your doctor, see ‘Side Effects’ section.
Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor, pharmacist or nurse before taking Plenvu if any of the points below apply to you. If you:
- have an allergy to any of the ingredients in Plenvu
- have heart problems and/or heart rhythm problems
- have kidney problems
- have problems with swallowing
- have a high or low blood salt level (e.g. sodium, potassium)
- have diabetes
- have any other medical conditions
Tell your doctor if you are pregnant or plan to become pregnant. Your doctor can discuss with you the risks and benefits involved.
Tell you doctor if you are breastfeeding. It is not known if Plenvu passes into your breast milk. You and your doctor should decide if you will take Plenvu while breastfeeding.
If you have not told your doctor about any of the above, tell him/her before you start taking Plenvu.
Taking other medicines
Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines (e.g. oral contraceptives, diuretics, calcium channel blockers, corticosteroids), as well as any you get without a prescription from your pharmacy, supermarket or health food shop.
Medicines taken by mouth may not be absorbed properly when taken within 1 hour before the start of Plenvu.
Your doctor and pharmacist have more information on which medicines to be careful with or avoid while taking this medicine.
If you need to thicken fluids in order to swallow them safely, Plenvu may counteract the effect of the thickener.
Plenvu with food and drink
Continue to drink clear fluids before, during, and after you take Plenvu, to help prevent fluid loss (dehydration). It is important for you to drink the additional recommended amounts of clear fluids. Your Doctor will tell you a ‘Nil By Mouth’ time when you should stop drinking.
Examples of clear fluids are water, clear soups, herbal tea, black tea or coffee (without milk), soft drinks/diluted cordials and clear fruit juices (without pulp).
When taking Plenvu you should continue to take plenty of clear fluids. The fluid content of Plenvu does not replace your regular fluid intake.
Important: Do not drink alcohol, milk, anything coloured red or purple (e.g. blackcurrant juice) or any other drinks containing pulp material and do not eat while taking Plenvu and until after your clinical procedure.
Two-day split dosing schedule and day before dosing schedule
On the day before the clinical procedure you can eat a light breakfast followed by a light lunch and must finish eating this meal at least 3 hours before you start taking Plenvu, after which you may only consume clear fluids.
Morning only dosing schedule
On the day before the clinical procedure you can eat a light breakfast followed by a light lunch, and clear soup and/or plain yogurt for dinner (which should be completed by approximately 8 pm). You may only consume clear fluids from after dinner on the evening before the clinical procedure. No breakfast is allowed on the morning of the clinical procedure.
Your Doctor may give you additional dietary advice which you should follow.

You must read, understand and follow the instructions for use.
Your doctor may prescribe the two-day split dosing schedule, the morning only dosing schedule or the day before dosing schedule depending on the scheduling of your clinical procedure.

Your doctor will tell you which dosing schedule to follow. DO NOT add any other ingredients to the doses.
How to prepare Plenvu Dose 1
- Open the carton and remove the Dose 1 sachet.
- Pour the contents of Dose 1 into a measuring container that can hold 500 mL of fluid.
- Add water (not chilled) to make up to 500 mL and stir until all the powder has dissolved. This may take up to approximately 8 minutes.
How to drink Plenvu Dose 1
Drink the 500 mL Plenvu Dose 1 solution slowly over 30 minutes. Try to drink a glassful every 10 to 15 minutes. Drink an additional 500 mL of clear fluid over the next 30 minutes. Water, clear soup, diluted cordials/clear fruit juice (without pulp), herbal tea, black tea or coffee (without milk) are all suitable.
How to prepare Plenvu Dose 2
- When you are ready to take Dose 2 pour the contents of Dose 2 Sachet A and Dose 2 Sachet B into a measuring container that can hold 500 mL of fluid.

At the time you were given, based on the recommended dosing schedule, drink the 500 mL Plenvu Dose 2 solution slowly over 30 minutes. Drink an additional 500 mL of clear fluid over the next 30 minutes.
In addition to Plenvu and the additional clear fluid after each dose, you are encouraged to drink extra clear fluid as needed to avoid thirst. Drinking clear fluids will help prevent fluid loss (dehydration). You must stop drinking all fluids at least 2 hours prior to your clinical procedure. Your doctor should tell you your ‘NIL BY MOUTH’ time.
What you should expect to happen
When you start drinking the Plenvu 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 Plenvu solution is working. You may have stomach area bloating before you have your first bowel movement.
If you follow these instructions, your bowel will be clean, and this will help you to have a successful clinical procedure. You should allow sufficient time after your bowel movements have subsided to travel to the clinic/ hospital.
If you forget to take it
If you forget to take Plenvu as instructed, take it as soon as you realise you have not taken it and contact your doctor, pharmacist or nurse for advice prior to the clinical procedure. It is important that you have allowed sufficient time to complete your course of Plenvu in order to ensure your bowel is fully cleaned at least 2 hours prior to the clinical procedure.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26 in Australia or 0800 764 766 in New Zealand) for advice, or go to the Accident and Emergency department at the nearest hospital, if you think that you or anyone else may have taken too much Plenvu.
