Femlax10 g powder for oral solution in sachet

macrogol 4000

The name of this medication is Femlax powder for oral solution in a sachet.

This medication contains Macrogol (PEG=Polyethylene Glycol) 4000.

Femlax is considered an osmotic laxative.

Femlax is used for the symptomatic relief of occasional constipation in adults and in children over 8 years old.

A organic disorder must be ruled out before starting treatment. It should be used along with lifestyle changes and an adequate diet (see section 2). It should not be used for more than 1 week of treatment, unless advised by a doctor.

You should consult your doctor if it worsens or does not improve after 7 days.

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 experienced 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.

The treatment includes, among others:

• Increasing the proportion of fiber in the diet (vegetables, whole bread, fruit).
• Increasing water and fruit juice intake.
• Increasing physical activity (exercise, walking, etc.).
• Rehabilitating the defecation reflex.

If symptoms persist despite dietary measures, an underlying cause should be considered and treated.

Do not takeFemlax:

• If you are allergic to Macrogol (= PEG = polyethylene glycol) or any of the other components of this medication (listed in section 6).
• If you have a disease that affects the intestine or colon (such as ulcerative colitis, Crohn's disease) or toxic megacolon associated with symptomatic stenosis.
• If you have abdominal pain of unknown cause.
• If you have or suspect you have a gastrointestinal perforation.
• If you have or suspect you have intestinal obstruction (ileus).
• Femlax should not be administered to children under 8 years old.

Warnings and Precautions

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

Patients should consult their doctor if they do not observe improvement or worsen after 7 days of treatment.

Due to the mechanism of action of macrogol, it is recommended to drink liquids during treatment with this medication.

In case of diarrhea, some patients may develop electrolyte disorders (decrease in certain salts in the blood), mainly elderly people, those with liver or kidney problems, or those taking diuretics (medications that facilitate the elimination of liquids). If you are any of these people, and experience diarrhea, you should review your electrolyte levels with a blood test.

Severe hypersensitivity reactions (rash, urticaria, and edema) have been reported with macrogol-containing medications. Rare cases of anaphylactic shock have been reported.

Use with caution in patients with altered nausea reflex, patients prone to regurgitation or aspiration, and patients with swallowing problems. In these cases, consult your doctor.

Avoid mixing Femlax with starch-based thickeners if you have swallowing problems. This may result in a watery liquid that could enter your lungs and cause pneumonia if you cannot swallow it properly.
