02 Question and Answers


Mutaflor® is presented in either a 20 or 100 capsule pack.

The capsules are enteric coated, reddish brown in colour and cannot be pulled apart. This colouring is part of the enteric coating and ensures that the capsule will not degrade and open until the start of the large intestine is reached. The capsule contents are a beige powder.


Mutaflor® is a probiotic that comprises as its active ingredient a viable non-pathogenic strain of Escherichia coli (E.coli).
Escherichia coli strain Nissle 1917

A Patient Information Leaflet (PIL) accompanies every pack and contains important information relating to the safe use of this product and lists all excipients.

Mutaflor® Suspension – for Paediatrics
Mutaflor® Mite – children’s variant capsule

We are often asked for these two Mutaflor variants and neither are currently registered in Australia. This will be reviewed again early 2018.

My Doctor has prescribed a different dosage to that on the Mutaflor carton
The dosage set out on the Mutaflor carton reflects that used in the clinical studies based on chronic constipation. Always follow the advice of your Doctor or healthcare practitioner.

My child can not swallow the capsule – can it be opened?

Small children for most part have difficulty swallowing capsules so the ‘work around’ for practitioners here is to simply cut open the capsule and add to food.

If your child can tolerate dairy, then yoghurt is the ideal delivery method.

The important point is that the capsule contents is added to a meal.
Not all the bacteria will survive transit to the large intestine but enough will to retain therapeutic effect and the rationale is the meal will help in moving the PH toward neutral and therefore a less acidic environment.

Some begin with half capsule but as not all colony forming units (CFU) will survive, a whole capsule may be more appropriate.
Always talk to your Doctor or Healthcare Practitioner regarding the correct dosage.
You may need to make adjustments for age and mass.

The ‘do not break open the capsule’ is because the capsule is enteric coated and designed not to open until the large intestine is reached.

There is no safety issues with opening the capsule but is not suggested other than for these cases.

The suspension offers no protection to the gastric environment.
It is of lower strength and approx. 3 times the cost.

Mutaflor® is available without prescription from any pharmacy, medical practice or healthcare practitioner that may choose to dispense the product themselves.
