What is Movicol-Half used for?

Movicol-Half is used in adults and children aged 2 years and older for the treatment of chronic constipation. Constipation is the less frequent than normal passing of large, firm or hard stools. Movicol-Half helps you to have a comfortable bowel movement even if you have been constipated for a long time.

Chronic Constipation in Children:

Most normal children will occasionally experience constipation, which will normally require no more than a healthy diet, plenty of exercise, regular toilet use and, sometimes, occasional use of laxatives.

However, a small proportion of children will pass stools less frequently than 3 times per week, with excessive straining and discomfort or pain at these times. If your child has this more severe type of constipation your doctor needs to be involved in making a supervised plan of treatment for your child over the next 6 -12 months. Treatments may require daily use of a product such as Movicol-Half which can keep stools of normal consistency and restore a normal pattern of passing stools.

Movicol-Half is also used in children aged 2 years and older for the treatment of faecal impaction (as determined by your doctor), and for the prevention of recurrence of faecal impaction.

Before you take Movicol-Half

Do not take Movicol-Half 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
  • an allergy to macrogol or any of the ingredients.

Pregnancy and breast feeding
If you are pregnant, talk to your doctor before you take Movicol-Half.

Movicol-Half can be taken whilst breast feeding.

Other Medications
Laxative products such as Movicol-Half have the potential to interact with other medications, by altering their absorption. Close monitoring of the effects of your medications may be necessary when you commence or cease to take Movicol-Half regularly. It is important that you should discuss this with your doctor.

How to take Movicol-Half

Chronic Constipation/Prevention of recurrence of faecal impaction:

Children aged 2-5 years: The usual starting dose is 1 sachet daily.

Children aged 6-11 years: The usual starting dose is 2 sachets daily. The dose should be adjusted up or down as required to produce regular soft stools. The maximum dose needed does not normally exceed 4 sachets daily.

Use in children aged 2 years and older should be limited to 12 weeks except under medical supervision.

Movicol-Half is not recommended for children below 2 years of age.

Adults and children 12 years and older: The recommended dose of Movicol-Half is 2 sachets a day. This can be increased up to 6 sachets daily if necessary, depending on the severity of your constipation. For chronic constipation the dose may be reduced to 1 sachet daily, according to individual response.

For patients 12 years and older using 2 sachets daily or more, it is recommended to use Movicol.

FAECAL IMPACTION:

Children (2 - 11 years):
A course of treatment with Movicol-Half is for up to 7 days as follows:


Treatment can be stopped when the medicine has worked. This is shown by the patient passing large volumes of stool or watery diarrhoea. It is not recommended to use Movicol-Half for the treatment of faecal impaction in children with a heart or kidney condition.

Open the sachet and pour contents into a cup. Add about 60 mL of water into the cup. Stir well until all the powder has dissolved and the Movicol-Half solution is clear or slightly hazy, then drink it. If you like, you can add a flavouring agent such as cordial to the drink.

For use in faecal impaction, the correct number of sachets can be made up in advance and kept covered and refrigerated for 24 hours. For example 12 sachets can be made up into 750 mL of water and 16 sachets into one litre of water.

Drink plenty of water and increase fibre in diet, except in cases of medication-induced constipation. Prolonged use of laxatives is undesirable and may lead to dependence. In some circumstances, prolonged use may be necessary but should only be under medical supervision.

Movicol-Half should not be used for the treatment of faecal impaction in children for longer than 7 days. If symptoms persist, see your doctor.

If you are taking Movicol-Half for constipation and get bad diarrhoea, stop taking Movicol-Half until it clears. If constipation recurs, you should check with your doctor or pharmacist before taking a new course of Movicol-Half. If you are worried, contact your doctor or pharmacist.

What about side effects?

Sometimes people have stomach ache or rumbles, or an allergic reaction, or feel bloated or sick. You may get diarrhoea, especially when you first start taking Movicol-Half. If you feel weak, breathless, very thirsty with a headache, or get puffy ankles stop taking Movicol-Half and tell your doctor. Tell your doctor or pharmacist if you think Movicol-Half is causing you any problem.

How to store Movicol-Half

Store your Movicol-Half at room temperature (below 25ºC). Do not use Movicol-Half after the expiry date on the label. Once you have made up Movicol-Half in water put it in the fridge (2-8ºC) and keep it covered. Throw away any solution not used within a 24 hour period. Keep all medicines away from children.

BRAND INFORMATION

Brand name

Movicol-Half Powder for oral solution

Active ingredient

Potassium chloride; Sodium chloride; Sodium bicarbonate; Macrogol 3350

Schedule

Unscheduled

 

Name of the medicine

Each sachet of Movicol-Half contains macrogol 3350 6.563 g, sodium chloride 175.4 mg, sodium bicarbonate 89.3 mg, potassium chloride 23.3 mg, lime and lemon flavour and potassium acesulfame as a sweetener.
The content of electrolyte ions per sachet when made up to 62.5 mL is: sodium 65 mmol/L, potassium 5.4 mmol/L, chloride 53 mmol/L, bicarbonate 17 mmol/L.

Pharmacology

Macrogol 3350 acts by virtue of its osmotic effect 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 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.
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.
The laxative action of macrogol has a time course which will vary according to the severity of the constipation being treated.

Faecal impaction.

In a noncomparative study in 27 adult patients, Movicol 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.
In a noncomparative study in 63 children, Movicol cleared the faecal impaction in 92% of patients within 3-7 days of treatment (median 6 days). For the 2-4 years age group, the average total number of sachets required was equivalent to 28.6 Movicol-Half sachets, and for the 5-11 age group the average total number of sachets required was equivalent to 47.2 Movicol-Half sachets.

Indications

For effective relief of constipation in adults. For treatment of chronic constipation in adults and children aged 2 years and older. For resolving faecal impaction, defined as refractory constipation with faecal loading of the rectum, or the rectum and colon, confirmed by physical examination of abdomen and rectum, in adults and children aged 2 years and older. For prevention of recurrence of faecal impaction in children aged 2 years and older. Use in children aged 2 years and older should be limited to 12 weeks except under medical supervision.

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 any of the ingredients.

Precautions

Adverse reactions are possible as described under Adverse Effects. If patients develop any symptoms indicating shifts of fluid/ electrolytes (e.g. oedema, shortness of breath, increasing fatigue, dehydration, cardiac failure) Movicol-Half 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 Movicol-Half (see Interactions with Other Medicines).
As with all laxatives, prolonged use is undesirable and may lead to dependence. If prolonged use is necessary, it should only be under medical supervision. Patients should be advised to drink plenty of water. They should also increase fibre in the diet, except in the case of medication induced constipation.

Use in pregnancy.

(Category B1)
There were no direct embryotoxic or teratogenic effects in rats at maternally toxic doses up to 40 g/kg/day, 51 x the maximum recommended dose in humans for chronic constipation and 19 x for faecal impaction.
Indirect effects, including reduction in fetal and placental weights, reduced fetal 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 embryofetal toxicity. There was no indication of a teratogenic effect.

Use in lactation.

No effects on the breastfed newborn/ infant are anticipated since the systemic exposure of the breastfeeding woman to macrogol 3350 is negligible. Movicol can be used during breastfeeding.

Use in children.

The safety and efficacy of Movicol-Half in the treatment of chronic constipation in children under two years of age has not been established.

Chronic constipation in children.

Constipation is the less frequent than usual passage of large, firm or hard stools. Most normal children will occasionally experience constipation, which will normally require no more than a healthy diet, plenty of exercise, regular toilet use and sometimes occasional use of laxatives. However, a small proportion of children will pass stools less frequently than 3 times per week, with excessive straining and discomfort or pain at these times. For these children a supervised plan of treatment over at 6-12 months utilising a product such as Movicol-Half to restore normal patterns of toilet use and stool formation may be considered appropriate. However, safety and efficacy of Movicol-Half has only been proved for a period of up to three months. Treatment should be stopped gradually and resumed if constipation recurs.

Mutagenicity and carcinogenicity.

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.
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.

Interactions

There is a possibility that the absorption of other medicinal products could be transiently reduced during use with Movicol-Half (see above). There have been isolated reports of decreased efficacy with some concomitantly administered medicinal products, e.g. antiepileptics. 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 Movicol-Half is overdosed to induce watery diarrhoea.

Adverse 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 Movicol-Half. Diarrhoea usually responds to dose reduction.
Adverse events are listed below by system order class.

Immune system disorders.

Allergic reactions, including anaphylaxis, angioedema, dyspnoea, rash, urticaria, and pruritus.

Metabolism and nutrition disorders.

Electrolyte disturbances, particularly hyperkalaemia and hypokalaemia.

Nervous system disorders.

Headache.

Gastrointestinal disorders.

Abdominal pain, diarrhoea, vomiting, nausea, dyspepsia, abdominal distension, borborygmi, flatulence, anorectal discomfort.

General disorders and administration site conditions.

Peripheral oedema.

Skin and subcutaneous disorders.

Erythema.

Dosage and Administration

Adults and children over 12 years.

Constipation.

The dose is 2 sachets daily. May be increased up to 6 sachets daily if required. For chronic constipation the dose may be reduced to 1 sachet daily, according to individual response.
For patients of 12 years and older using 2 sachets daily or more, it is recommended to use Movicol.

Faecal impaction.

16 sachets daily, all of which should be consumed within 6 hours. A course of treatment for faecal impaction does not normally exceed 3 days.
For patients of 12 years and older it is recommended to use Movicol.

Children 2 years and older.

Chronic constipation and prevention of recurrence of faecal impaction.

Children aged 2-5 years.

The usual starting dose is 1 sachet daily.

Children 6-11 years.

The usual starting dose is 2 sachets daily.
The dose should be adjusted up or down as required to produce regular soft stools. The maximum dose does not normally exceed 4 sachets a day.
Use in children aged 2 years and older should be limited to 12 weeks except under medical supervision.
Movicol-Half is not recommended for children below 2 years of age.

Faecal impaction.

Children 2-11 years.

A course of treatment for faecal impaction with Movicol-Half is for up to 7 days (see Table 1).
The dosage regimen in Table 1 should be stopped once disimpaction has occurred. An indicator of disimpaction is the passage of a large volume of stools. After disimpaction, it is recommended that the child follows an appropriate bowel management program to prevent reimpaction.
Movicol-Half is not recommended for children under 2 years of age.

Patients with impaired cardiovascular function.

Adults and children over 12 years.

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

Children (2-11 years).

There are no clinical data for this group of patients, therefore Movicol-Half is not recommended for use in this patient group.

Patients with renal insufficiency.

Adults and children over 12 years.

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

Children (2-11 years).

There are no clinical data for this group of patients, therefore Movicol-Half is not recommended for use in this patient group.

Administration.

For oral administration. Each sachet should be dissolved in ¼ cup (about 60 mL) water.
For use in faecal impaction the correct number of sachets can be reconstituted in advance and kept covered and refrigerated for 24 hours. For example, 12 sachets can be made up into 750 mL of water and 16 sachets into one litre of water.

Overdosage

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 131 126.
