The name of this medicine is PEGLAX, powder for oral solution in sachet.
PEGLAX is considered as osmotic laxative.
PEGLAX is used for the symptomatic treatment of constipation in adults and children 8 years old and over. It should be used with appropriate changes to lifestyle and diet (see section 2).
You must talk to a doctor if you do not feel better or if you feel worse.
This medicine contains Macrogol (P.E.G. = polyethylene glycol).
In the case of constipation, the maximum treatment period in children is 3 months
Occasional constipation may be related to a recent change in your lifestyle. There are medicines that can be used for short term treatment. Ask the opinion of your doctor in the case of recent constipation which cannot be explained by changes in your lifestyle, or in the case of constipation associated with pain, fever or abdominal swelling.
Chronic constipation may be caused by:
- Intestinal disease that requires a physician´s advice.
- Intestinal dysfunction (imbalance) due to dietary habits and lifestyle.
The treatment includes among others:
- An increase in the proportion of fibre in the diet (vegetables, wholegrain bread and fruit);
- Increase water and fruit juice intake;
- Increase physical activity (sports, walking ...)
- Rehabilitation of defecation reflex.
- If you are allergic to Macrogol (P.E.G. = polyethylene glycol) or any of the other ingredients of this medicine (listed in section 6).
- If you have any intestine or colon disease (such as ulcerative colitis, Crohn's disease).
- If you have abdominal pain of undetermined cause.
- If you have or suspect a gastrointestinal perforation.
- If you have or suspect a bowel obstruction
Talk to your doctor, pharmacist or nurse before taking PEGLAX.
If you develop diarrhoea following treatment with PEGLAX you may be at risk of developing electrolytec disorders (a decrease in certain salts in the blood). You are more likely to be at risk if you are an older person, or have liver or kidney problems, or are taking diuretics (water tablets). If you are one of these people and you develop diarrhoea you should see your doctor to have your electrolyte levels checked with a blood test.
Ask your doctor´s opinion before administering this treatment to your child, in order to exclude any organic cause of constipation. After 3 months of treatment, your doctor should evaluate your child clinical condition.
PEGLAX may delay the absorption of other medicines, making them less effective or ineffective especially those with a narrow therapeutic index (e.g antiepileptics, digoxin and immunosuppressive agents). Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine

For oral use.
The usual dose is:
The recommended dose is: 1 to 2 sachets per day, preferably taken as a single dose in the morning.
It is recommended to drink 125 ml of liquids (e.g. water) after each dose.
The daily dose should be adjusted according to the clinical effects obtained and may range from one sachet every other day (especially in children) to up to a maximum of 2 sachets per day.
The effect of PEGLAX occurs within 24 to 48 hours after administering.
Dissolve the content of the sachet in a glass of water (at least 125 ml) immediately before use and drink the liquid.
Improvement in the frequency of your bowel movements after taking Casenlax can be maintained by keeping to a healthy lifestyle and diet.
For children, the treatment must not exceed 3 months due to a lack of clinical data from more than 3 months treatments.
Treatment should be stopped gradually and resumed if constipation recurs.
You can develop diarrhoea, abdominal pain and vomiting which disappears when treatment is temporarily interrupted or the dose is reduced.
If you suffer from severe diarrhoea or vomiting you should contact a doctor as soon as possible as you may require treatment to prevent loss of salts (electrolytes) from fluid loss.
Do not take a double dose to make up for a forgotten dose.
