Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Molaxole Powder for Oral Solution.

What is in this leaflet

This leaflet answers some common questions about MOLAXOLE. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

The information in this leaflet was last updated on the date listed on the final page. More recent information on the medicine may be available. You should ensure that you speak to your pharmacist or doctor to obtain the most up to date information on the medicine.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine.

You may need to read it again.

What MOLAXOLE is used for

MOLAXOLE helps you to have a comfortable bowel movement even if you have been constipated for a long time.

MOLAXOLE also works in very bad constipation (called faecal impaction), as determined by your doctor.

Macrogol 3350 increases the volume of faeces by binding water leading to a normalisation of motility in the colon. The physiological consequences are an increased movement of the softened stools and easing of defaecation. The salts in the formulation help maintain the body's normal salt and water balance.

This medicine is available without a doctor's prescription. However, you still need to take MOLAXOLE carefully to get the best results from it.

Before you take MOLAXOLE

When you must not take it

Do not take MOLAXOLE if you have an allergy to any of the ingredients listed at the end of this leaflet.

Do not give this medicine to a child under the age of 12 years.

Do not take MOLAXOLE if your doctor has told you that you have:

  • An obstruction in your intestine (gut)
  • A perforated gut wall
  • Severe inflammatory bowel disease like ulcerative colitis, Crohn's disease or toxic megacolon
  • Paralysis of the bowel

Do not take MOLAXOLE after the expiry date printed on the pack. If you use this medicine after the expiry date has passed, it may not work as well.

Do not take MOLAXOLE if the packaging is torn or shows signs of tampering.

If you are not sure whether you should start taking MOLAXOLE, consult your doctor or pharmacist.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor or pharmacist if you are pregnant or plan to become pregnant, or are breastfeeding. Your doctor or pharmacist will discuss the possible risks and benefits of taking MOLAXOLE during pregnancy or breastfeeding.

If you have not told your doctor or pharmacist about any of the above, tell them before you start taking MOLAXOLE.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you can get without a prescription from your pharmacy, supermarket or health food shop.

Laxative products such as MOLAXOLE have the potential to interact with other medicines by altering their absorption. Some medicine, e.g. anti-epileptics, may not work as effectively during use with MOLAXOLE. It may be necessary to closely monitor your medications when you commence or cease taking MOLAXOLE regularly. It is important that you discuss this with your pharmacist or doctor.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take MOLAXOLE

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How much to take

Dosage in adults and children over 12 years of age:

Constipation

The recommended dose of MOLAXOLE is 1 sachet a day. This may be increased up to 3 sachets daily if necessary.

Faecal impaction as diagnosed by a doctor

The dose is 8 sachets a day taken within 6 hours. You may need to take this dose for up to 3 days.

Patients with impaired cardiovascular function:

If you have a heart condition, do not take more than 2 sachets in any one hour.

Patients with renal insufficiency:

No dosage change is necessary for treatment of either constipation or faecal impaction.

Do not exceed the recommended dose.

If you are not sure of the correct dose or how to use this medicine, ask your pharmacist or doctor.

How to take it

Mix the contents of 1 sachet with a 1/2 glass of water (about 125 mL). Stir well until all the powder has dissolved and drink it. If you like, you can add fruit juice or fruit syrup immediately before drinking.

If you are taking MOLAXOLE for the treatment of faecal impaction, you can mix 8 sachets in 1 litre of water. The solution can then be stored in the fridge.

Drink plenty of water and increase fibre in diet except in cases of medication-induced constipation.

How long to take it

Continue taking your medicine for as long as your doctor tells you.

If you forget to take it

If you miss a dose, take MOLAXOLE when the next dose is due. Do not take a double dose to make up for the dose that you missed.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

If you take too much MOLAXOLE and get bad diarrhoea, stop taking MOLAXOLE until it clears. If constipation recurs, you should check with your doctor or pharmacist. If you are worried, contact your doctor or pharmacist.

While you are taking MOLAXOLE

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking MOLAXOLE.

Tell any other doctors, dentists, and pharmacists who treat you that you are using this medicine.

If you become pregnant while you are using this medicine, tell your doctor. Your doctor can discuss with you the risks of using it while you are pregnant.

Things to be careful of

Prolonged use of laxatives is undesirable and may lead to dependence. If symptoms persist, seek medical advice.

Side effects

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may not experience any of them.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • Stomach ache or rumbles
  • Bloating
  • Feeling sick
  • Diarrhoea (especially when starting to take MOLAXOLE)

Stop taking MOLAXOLE and tell your doctor if you experience any of the following:

4 Clinical Particulars

4.1 Therapeutic Indications

For effective relief from constipation, treatment of chronic constipation and treatment of faecal impaction defined as refractory constipation with faecal loading of the rectum and/or colon confirmed by physical examination of abdomen and rectum.

4.2 Dose and Method of Administration

Dosage in adults and children over 12 years.

Constipation.

The dose is 1 sachet daily. This may be increased up to 3 sachets daily, if required.

Faecal impaction as diagnosed by a doctor.

8 sachets daily, consumed within 6 hours. A course of treatment for faecal impaction does not normally exceed 3 days.

Patients with impaired cardiovascular function.

For the treatment of faecal impaction the dose should be divided so that no more than two sachets are taken in any one hour.

Patients with renal insufficiency.

No dosage change is necessary for treatment of either constipation or faecal impaction.

Administration.

For oral administration. Each sachet should be dissolved in 125 mL water. For faecal impaction, 8 sachets may be dissolved in 1 litre of water and stored well covered in the fridge for up to 6 hours (see Section 6.4 Special Precautions for Storage).

4.3 Contraindications

Intestinal perforation or obstruction due to structural or functional disorder of the gut wall, ileus and severe inflammatory conditions of the intestinal tract, such as Crohn's disease, ulcerative colitis and toxic megacolon. Known hypersensitivity to the active substances or any of the excipients.

4.4 Special Warnings and Precautions for Use

Adverse reactions are possible as described (see Section 4.8 Adverse Effects (Undesirable Effects)). If patients develop any symptoms indicating shifts of fluid/electrolytes (e.g. oedema, shortness of breath, increasing fatigue, dehydration, cardiac failure) Molaxole should be stopped immediately and electrolytes measured, and any abnormality should be treated appropriately.
The absorption of other medicinal products could transiently be reduced due to a decrease in gastrointestinal transit time induced by Molaxole (see Section 4.5 Interactions with Other Medicines and Other Forms of Interactions).
As with all laxatives, prolonged use is undesirable and may lead to dependence. Patients should be advised to drink plenty of water and increase fibre in the diet except in cases of medication-induced constipation.

Use in renal impairment.

See Section 4.2 Dose and Method of Administration, Patients with renal insufficiency.

Use in the elderly.

No data available.

Paediatric use.

Not recommended for children below 12 years of age, as there is no clinical data for use of Molaxole in children below 12 years of age.

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

There is a possibility that the absorption of other medicinal products could be transiently reduced during use with Molaxole (see Section 4.4 Special Warnings and Precautions for Use). There have been isolated reports of decreased efficacy with some concomitantly administered medicinal products, e.g. anti-epileptics. A theoretical potential also exists for decreased absorption (rate and extent) of drugs which are generally poorly absorbed or are contained in sustained or modified release dosage forms. This is more likely to occur if Molaxole is overdosed to induce watery diarrhoea.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

No data available.
(Category B1)
There were no direct embryotoxic or teratogenic effects in rats at maternally toxic doses up to 40 g/kg/day, 51x the maximum recommended dose in humans for chronic constipation and 19x for faecal impaction.
Indirect effects, including reduction in foetal and placental weights, reduced foetal viability and abortions, were noted in the rabbit at doses below the maximum recommended human dose. Rabbits are particularly sensitive to the effects of GI acting substances, and the findings are considered most likely a reflection of poor maternal condition as a result of an exaggerated pharmacodynamic response rather than direct embryofoetal toxicity. There was no indication of a teratogenic effect.
No effects on the breastfed newborn/infant are anticipated since the systemic exposure of the breast-feeding woman to macrogol 3350 is negligible. Molaxole can be used during breast-feeding.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

Reactions related to the gastrointestinal tract occur most commonly. These reactions may occur as a consequence of expansion of the contents of the gastrointestinal tract, and an increase in motility due to the pharmacologic effects of Molaxole. Diarrhoea usually responds to dose reduction. See Table 1.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

Severe pain or distention can be treated by nasogastric aspiration. Extensive fluid loss by diarrhoea or vomiting may require correction of electrolyte disturbances.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia) or 0800 POISON or 0800 764 766 (New Zealand).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Macrogol 3350 exerts an osmotic action in the gut, which induces a laxative effect. Macrogol 3350 increases the stool volume, which triggers colon motility via neuromuscular pathways. The physiological consequence is an improved propulsive colonic transportation of the softened stools and a facilitation of the defaecation. Electrolytes combined with macrogol 3350 are exchanged across the intestinal barrier (mucosa) with serum electrolytes and excreted in faecal water without net gain or loss of sodium, potassium and water.

Clinical trials.

The laxative action of macrogol 3350 has a time course which will vary according to the severity of the constipation being treated. Faecal Impaction - In a non-comparative study in 27 adult patients, macrogol 3350, sodium chloride, sodium bicarbonate and potassium chloride cleared the faecal impaction in 12/27 (44%) after 1 day's treatment, 23/27 (85%) after 2 day's treatment and 24/27 (89%) at the end of 3 days. Controlled comparative studies have not been performed with other treatments (e.g. enemas).

5.2 Pharmacokinetic Properties

Macrogol 3350 is unchanged along the gut. It is virtually unabsorbed from the gastrointestinal tract. Any macrogol 3350 that is absorbed is excreted via the urine.

5.3 Preclinical Safety Data

Genotoxicity.

Preclinical studies provide evidence that macrogol 3350 has no significant systemic toxicity potential, based on conventional studies of pharmacology, repeated dose toxicity, genotoxicity and toxicity to reproduction.

Carcinogenicity.

There are long-term animal toxicity and carcinogenicity studies involving macrogol 3350. Results from these and other toxicity studies using high levels of orally administered high molecular weight macrogols provide evidence of safety at the recommended therapeutic dose.
