Portalac or Dufalac, which is more effective

The preparations “Portalac” and “Dufalac” are absolute analogues. They contain lactose in a dosage of 66, 7 g per 100 ml and purified water. Both are prescribed for the same diagnoses: constipation, dysbiosis, salmonellosis, hepatic encephalopathy, hemorrhoids and the recovery period after surgery. Also, both drugs are safely prescribed for women during pregnancy and lactation. They are not dangerous for the treatment of newborn children.

Contraindications and side effects are the same. Both of these drugs are not instantaneous. The result can be obtained after 12 to 48 hours, and the recommended time of use is at least three weeks (up to a month).

Among the differences between these drugs can be called the country of origin (“Dufalac” – the Netherlands, “Portalac” – Croatia), prices also differ. Dufalac is more expensive.

Preparations of this type can be used by all, without exception. They are not addictive, have a mild effect. They are even suitable for newborns, because babies in the first months of life often have problems with bowel movements. To give the baby medicine, you need to take a regular 5 ml syringe without a needle, put syrup into it and squeeze 1 ml of the drug onto the inside of the baby’s cheek.

From the foregoing, we can conclude that Portalac and Dufalac are absolute analogues that equally effectively affect a delicate problem. They can be easily interchanged.

With constipation, intestinal function is disturbed, a putrefactive microflora occurs, in which dangerous toxins actively develop. All this poisons the human body and leads to pathological changes. You can not neglect this condition, you need to balance the diet and strive to restore the function of the gastrointestinal tract. But there are situations when you have to resort to the help of laxatives. In such cases, you need to choose the safest names, pay attention to such paragraphs of the instructions as contraindications and addiction, and it is best to consult a specialist. He will prescribe the drug and the necessary dosage in accordance with the individual characteristics of the body.

Speaking of safe drugs, we can distinguish an osmotic group among them . Such drugs contribute to fluid retention in the intestines. Because of this, the volume of its contents increases and peristalsis begins to work actively, which, in fact, caused a laxative result. One of these drugs are lactulose laxatives “Dufalac” and “Portalac”.

 The remedy for constipation “Portalac”

It is a sweet, but very viscous syrup, comes in bottles of 250 and 500 ml. The main component is lactulose with a dosage of 66.7 per 100 ml. It is used not only for constipation, but also for dysbiosis and the medical need to soften the stool (for hemorrhoids, before surgery), and also to avoid hepatic coma (with the complex treatment of encephalopathy). With all the safety of this drug, it is worth considering cases when it is not prescribed:

  • Allergy.
  • Galactosemia.
  • Intestinal obstruction.
  • The risk of perforation and perforation of the digestive tract.

During pregnancy and lactation, “Portalac” is not contraindicated, its use is allowed, since the composition of the syrup cannot harm the fetus and does not penetrate into breast milk.


The medicine tastes good, but you can drink it with water if it seems too cloying. It is recommended to take it in the morning, before breakfast, but you may need to take it 2 times a day, that is, before bedtime, a second dose. To achieve the desired stool, adults begin to take it from 15 ml, gradually bringing it to 45 ml. After stool is established, the dosage is reduced to 30 ml. For children, the dosage depends on age. So, children up to a year can take 5 ml per day, up to 6 years – up to 10 ml, from 7 to 14 years – up to 15 ml per day. It is important to remember that during treatment with this remedy it is necessary to drink a minimum of 1.5-2 liters of water. The entire course of treatment must be made individually with the help of a specialist.

Neglecting dosage recommendations can be hazardous to health. Possible abdominal pain and diarrhea. In such cases, taking “Portalac” should be discontinued and symptomatic treatment of the arising pain should begin. Also, with diarrhea, you need to take a drug that restores the water-salt balance. But do not stop treatment for constipation if in the first days of admission there is increased gas formation or nausea. It will pass in a couple of days.


Dufalac can be found in the form of a viscous syrup in yellow. The drug also belongs to the osmotic group of laxatives with the same active substance – lactulose. Lactulose breaks down in the intestines with the help of bacteria and turns into organic acids. They lower acidity in the colon and increase fecal volume. This whole procedure stimulates intestinal motility and constipation is eliminated.


The action of the drug with dysbiosis is also effective. Lactulose stimulates the appearance of beneficial bacteria (bifidobacteria, lactobacilli), which stops the growth of harmful bacteria (E. coli, clostridia).

“Duphalac” is prescribed for any manifestation of constipation, as well as for hemorrhoid cones and before possible surgical operations. It is used in the complex treatment of hepatic encephalopathy.

There are also situations when taking this drug is excluded:

  • Acute intestinal obstruction.
  • Galactosemia.
  • Lactose intolerance.
  • Tendency to intestinal bleeding.
  • Diabetes.

During pregnancy and during lactation, the drug is safe.

This medicine has a sickly sweet taste, so you can take it both in pure form or diluted in water. The system of taking the drug is no different from the method of taking “Portalac”, and with excessive intake there may be the same consequences. Actions with an overdose are to stop taking the medicine.

What are the similar means
  • The composition is identical.
  • Indications for use are the same.
  • Contraindications and side effects are the same. Side effects may occur due to improper use of drugs and if the dosage is exceeded. They manifest as nausea, vomiting, diarrhea, cramping and pain in the intestines.
