Doctor consultation

Not sure if this medicine is right for you?

Discuss your symptoms and treatment with a doctor online.

2. What you need to know before starting to take Casenlax

Occasional constipation:

Occasional constipation may be related to a recent change in lifestyle. There are medications that can be used for short-term treatment. Consult your doctor if you have recently suffered from constipation not due to changes in your lifestyle or constipation associated with pain, fever, or abdominal inflammation.

Chronic constipation (long-term constipation):

Chronic constipation may be caused by: • Intestinal disease that requires consulting a doctor. • Intestinal dysfunction (imbalance) due to dietary habits and lifestyle.

Treatment includes, among others: • An increase in the proportion of fiber in the diet (vegetables, whole wheat bread, fruit).

  • Increased water and fruit juice intake.
  • Increased physical activity (exercise, walking...).
  • Rehabilitation of the defecation reflex.

Do not take Casenlax:

  • If you are allergic to Macrogol (PEG = polyethylene glycol) or to any of the other components of this medication (included in section 6).
  • If you have a disease that affects the intestine or colon (such as ulcerative colitis, Crohn's disease).
  • If you have abdominal pain of unknown cause.
  • If you have or suspect you may have a gastrointestinal perforation.
  • If you have or suspect you may have an intestinal obstruction.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Casenlax.

In the event of diarrhea, after treatment with Casenlax, you may be at risk of developing electrolyte disorders (decrease in certain salts in the blood). You are more likely to be at risk if you are an elderly person, or have liver or kidney problems, or are taking diuretics (medications that facilitate the elimination of fluids). If you are one of these people and experience diarrhea, you should visit your doctor to review your electrolyte levels with a blood test.

Children

Ask your doctor before administering this treatment to your child, to rule out that the constipation is caused by an organic problem. After 3 months of treatment, your doctor should evaluate your child's clinical condition.

Use of Casenlax with other medications

Casenlax may delay the absorption of other medications, making them less effective or ineffective, especially those with a narrow therapeutic index (e.g., antiepileptics, digoxin, and immunosuppressants). Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.

Pregnancy and lactation

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Pregnancy

Casenlax can be taken during pregnancy.

Breastfeeding

Casenlax can be taken during breastfeeding.

Driving and using machines

Casenlax has no influence on the ability to drive and operate machinery.

Casenlax contains an insignificant amount of sugar or polyols, and therefore can be prescribed to diabetic patients or patients on a galactose-free diet.

Casenlax contains sodium benzoate

This medication contains 4 mg of sodium benzoate E211 in each sachet.

Casenlax contains sodium

This medication contains less than 1 mmol of sodium (23 mg) per sachet; it is essentially "sodium-free".

3. How to take Casenlax

Follow the administration instructions of this medication exactly as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

Oral route.

The recommended dose is: 1 or 2 sachets per day, preferably taken in a single dose in the morning. It is recommended to drink 125 ml of liquids (e.g., water) after each dose.

1 sachet contains 20 ml of oral solution and 10 g of macrogol 4000.

The daily dose should be adapted based on the clinical effects obtained and may range from 1 sachet every 2 days (especially in children) to a maximum of 2 sachets per day.

The effect of Casenlax occurs 24-48 hours after administration.

The improvement in intestinal transit after administration of Casenlax will be maintained by following a healthy lifestyle and diet.

Use in children and adolescents

In children, treatment should not exceed 3 months due to the lack of clinical trial data for more than 3 months of treatment.

Treatment should be gradually discontinued and resumed if constipation recurs.

If you take more Casenlax than you should

You may develop diarrhea, abdominal pain, and vomiting that disappear when treatment is temporarily interrupted or the dose is reduced.

If you experience significant diarrhea or vomiting, you should contact your doctor as soon as possible, as you may need treatment to prevent electrolyte loss due to fluid loss.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone: 91 562 04 20 (indicating the medication and the amount ingested).

If you forget to take Casenlax

Do not take a double dose to make up for forgotten doses.
