The contents of one sachet should be dissolved in one liter of water and consumed immediately. One liter of the solution should be drunk within one hour. The dosage depends on body weight and the doctor's recommendations – typically, 3 to 4 liters of the solution are taken, divided into an evening and a morning dose, or taken entirely in the evening.

When should you not use this medicine?

It should not be used if you are allergic to any of the ingredients, have severe heart failure, dehydration, advanced cancer, intestinal obstruction or perforation, acute intestinal inflammation (e.g., Crohn's disease), gastric emptying disorders, or in children and adolescents under 18 years of age.

Does Fortrans interact with other medicines?

Yes. Diarrhea caused by the medicine may interfere with the absorption of other medicines, which may reduce their effectiveness. This includes, among others, medicines used for heart diseases (e.g., digoxin), anti-epileptic drugs, blood-thinning drugs (coumarins), and immunosuppressive drugs.

What are the possible side effects of Fortrans?

Nausea, bloating, abdominal pain, and vomiting occur frequently. Frequent loose stools are a normal symptom. You must stop use immediately and contact a doctor if an allergic reaction occurs (rash, hives) or a severe reaction (swelling of the face or throat, difficulty breathing, dizziness).

What precautions should be taken when using the medicine?

Caution should be exercised in cases of heart disease, kidney disease, swallowing disorders, and when using diuretic medicines. The medicine contains high amounts of sodium and potassium, which is important for individuals on low-sodium diets or those with kidney problems.

1. What Fortrans is and what it is used for

Fortrans is used in adults to cleanse the bowel before an examination or surgical procedure involving the intestine.
Fortrans is an osmotic laxative containing macrogol of high molecular weight (polyethylene glycol, PEG) and additional electrolytes. Fortrans increases the amount of fluid in the intestine, resulting in more frequent watery bowel movements, which leads to bowel cleansing.

2. Important information before using Fortrans

When not to use Fortrans:

  • if the patient is allergic to macrogol (PEG), anhydrous sodium sulfate, sodium bicarbonate, sodium chloride, potassium chloride, or any of the other ingredients of this medicine (listed in section 6);
  • if the patient has severe heart failure;
  • if the patient is in a serious general condition, e.g. is dehydrated;
  • if the patient has advanced stage cancer or another disease leading to excessive fragility of the mucous membrane;
  • if the patient has acute inflammatory bowel disease, including Crohn's disease and ulcerative colitis;
  • if the patient has gastrointestinal tract perforation or an increased risk of gastrointestinal tract perforation;
  • if the patient has colitis or toxic megacolon;
  • if the patient has intestinal obstruction or suspected intestinal obstruction;
  • if the patient has gastric emptying disorders (such as gastroparesis - delayed gastric emptying);
  • in children and adolescents under 18 years of age.

Warnings and precautions
Fortrans may be used in elderly patients with poor general health only under medical supervision.
This medicine contains macrogol. Allergic reactions (including rash, urticaria, and severe allergic reaction with sudden swelling of the face, lips, tongue, wheezing or shortness of breath) have been reported after administration of products containing macrogol.
Diarrhea induced by Fortrans may significantly impair the absorption of concomitantly administered medicines (see section Fortrans and other medicines).
If the patient is at risk of electrolyte imbalance (disturbances in water-electrolyte balance), for example patients with renal failure, heart failure, or those taking diuretics, the doctor may decide to monitor blood electrolyte levels before and after administration of Fortrans. Caution is advised when using Fortrans in patients prone to water-electrolyte imbalances.
Before taking Fortrans, consult a doctor or pharmacist if:

  • the patient has heart disease (including heart failure);
  • the patient has kidney disease;
  • the patient has swallowing disorders or risk of aspiration (food or fluid entering the respiratory tract);
  • the patient is seriously ill;
  • the patient is taking diuretics (medicines that increase urine production).

If during administration of Fortrans for bowel cleansing the patient develops sudden abdominal pain or rectal bleeding, contact a doctor or seek immediate medical attention.
Children and adolescents
Fortrans is not intended for use in patients under 18 years of age. Safety and efficacy have not been established in this population.
Fortrans and other medicines
Inform your 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.
Diarrhea resulting from the use of Fortrans may cause significant disturbances in the absorption of concomitantly administered medicines. The absorption of other medicines, such as digoxin (used in heart diseases), anticonvulsants, coumarins (blood-thinning medicines), and immunosuppressive medicines (used, for example, in cancer treatment and after organ transplantation) may be temporarily reduced during treatment with Fortrans, which may decrease their effectiveness.
Pregnancy, breastfeeding and fertility
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to have a child, she should consult a doctor or pharmacist before using this medicine.
Fortrans contains sodium and potassium
The medicine contains 2.890 g of sodium (main component of table salt) per sachet. This corresponds to 144.5% of the maximum recommended daily dietary sodium intake for adults.
This should be taken into account in patients on a strict low-sodium diet.
Fortrans contains 393 mg of potassium per sachet, which should be considered in patients with impaired kidney function and in patients controlling potassium intake in their diet.

3. How to use Fortrans

Fortrans must always be used according to the doctor's instructions. If in doubt, consult a doctor or pharmacist.
Fortrans is intended for use in adults only. The recommended dose is approximately one litre of solution per 15 to 20 kg of body weight, corresponding to an average dosage of 3 to 4 litres of solution.
To obtain one litre of solution, the contents of one sachet should be dissolved in one litre of water. Mix thoroughly until the powder is completely dissolved. After dissolving the powder, administration of the solution should begin immediately. One litre of solution should be taken within one hour.
Fortrans can be administered:
in divided doses:

  • either 2 litres in the evening on the day before the examination or procedure and 1–2 litres in the morning on the day of the examination or procedure;
  • or 3 litres in the evening on the day before the examination or procedure and 1 litre in the morning on the day of the examination or procedure;

in a single dose:

  • 3–4 litres in the evening on the day before the examination or procedure, with a possible 1-hour break after drinking 2 litres of solution.

According to medical advice, drink one 250 ml glass of solution every 10 to 15 minutes.
It is recommended that the patient take the last portion of the solution 3–4 hours before the examination or procedure.
Taking more Fortrans than recommended
If the patient thinks they have taken too much Fortrans, inform the doctor and drink sufficient water or clear fluids to prevent dehydration.
