1. What is Casenlax and what is it used for

The name of this medicine is Casenlax 4g powder for oral solution in sachet.

Casenlax belongs to a group of medicines called osmotic laxatives. Osmotic laxatives are medicines 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 your doctor if it worsens or does not improve.

This medicine contains Macrogol (PEG = Polyethylene Glycol).

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

In the event of diarrhea, after treatment with Casenlax, some patients may develop electrolyte disorders (decrease in sodium and other salts in the blood), mainly elderly people, those with liver or kidney problems, or those taking diuretics (medicines 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 medicines

Casenlax 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 immunosuppressants). Inform your doctor or pharmacist if you are using or have recently used or may need to use any other medicine.
