2. What you need to know before you take Casenlax

Occasional constipation:

Occasional constipation may be related to a recent change in lifestyle. There are medicines 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).

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

Do not take Casenlax:

  • If you are allergic to Macrogol (PEG = polyethylene glycol) or any of the other components of this medicine (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 (ileus).

Warnings and precautions

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

In case of diarrhea, some patients may develop electrolyte disorders (decrease in certain salts in the blood), mainly elderly people, 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 review your electrolyte levels with a blood test.

Children

Ask your doctor before administering this treatment to your children, to rule out that 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 taking, have recently taken, or may need to take any other medicine.

Pregnancy and breastfeeding

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

Casenlax contains sodium

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

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.

Use in children and adolescents

If you take more Casenlax than you should

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

If you suffer from 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.
