1. What is Forlax 10 g and what is it used for
Forlax 10 g contains macrogol 4000 as the active substance and belongs to a group of medicines called osmotic laxatives. It works by increasing the amount of water in the stool, which helps to overcome problems related to slow bowel movements. Forlax 10 g is not absorbed into the bloodstream and is not broken down in the body.
Forlax 10 g is used for the symptomatic treatment of constipation in adults and children from 8 years of age.
The medicine is in the form of a powder, which should be dissolved in a glass of water (at least 50 ml) and drunk. The medicine usually takes 24 to 48 hours to work.
Treatment of constipation with medicines should only supplement a healthy lifestyle and diet.

Warnings and precautions
There have been reports of allergic reactions, including rash and swelling of the face or throat (anaphylaxis) after taking products containing macrogol (polyethylene glycol) in adults. Single severe allergic reactions have been reported, which led to fainting, collapse, or difficulty breathing and caused general malaise. If such symptoms occur, stop taking Forlax 10 g and consult a doctor immediately.
Since this medicine may sometimes cause diarrhea, before taking it, consult a doctor or pharmacist if:
- there is impaired liver or kidney function,
- diuretics (diuretic medicines) are being taken or in the case of elderly people, as they may be at increased risk of low sodium (salt) or potassium levels in the blood.
Before taking Forlax, consult a doctor or pharmacist if the patient has swallowing disorders.
In patients with swallowing difficulties, avoid mixing Forlax 10 g - a laxative containing macrogol (polyethylene glycol) - with food thickeners based on starch. This may cause the formation of a watery liquid that can enter the lungs and cause pneumonia.
Forlax 10 g and other medicines
When using Forlax, there may be a temporary decrease in the absorption of other medicines, leading to a decrease in their effectiveness, particularly for medicines with a narrow therapeutic index or short half-life, such as digoxin, antiepileptic drugs, coumarins, and immunosuppressants.
Tell the doctor or pharmacist about all medicines the patient is currently taking or has recently taken, as well as any medicines the patient plans to take.
Forlax 10 g may reduce the effectiveness of thickeners used in cases where fluids need to be thickened for safe swallowing.
