1. What is Casenlax and what is it used for

The name of this medication is Casenlax 500 mg/ml Oral Solution.

Casenlax belongs to a group of medications called osmotic laxatives. Osmotic laxatives are medications that allow the amount of water in the stool to increase, making it easier to pass.

Casenlax is indicated for the symptomatic treatment of constipation in children from 6 months to 8 years. It should be used in conjunction with appropriate lifestyle changes and a suitable diet (see section 2).

You should consult a doctor if your symptoms worsen or do not improve.

This medication contains Macrogol (PEG = Polyethylene Glycol).

In the case of constipation, the maximum treatment period in children is 3 months.

Do not take Casenlax

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 (decreased levels of certain salts in the blood). You are more likely to be at risk if you are an elderly person, 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 check 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.

Using 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 using, have recently used, or may need to use any other medication.

Treatment should be gradually discontinued and resumed if constipation recurs.

If you take more Casenlax than you should

It may cause 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 loss of electrolytes 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). It is recommended to bring the package and package leaflet to the healthcare professional.
