Frequently asked questions

When should you not take Lattulac EPS?

You must not take it if you are allergic to the active substance or any of the other components, if you suffer from galactosemia (a hereditary disease that prevents the metabolism of galactose), or if you have disorders that cause intestinal obstruction.

How should the medicine be taken?

The method of administration depends on the pharmaceutical form: the granules should be dissolved in water, milk, or other beverages; the syrup should be taken according to the prescribed doses; the rectal solution should be prepared by dissolving the crystals in one liter of lukewarm water at 37°C and administered via a rectal cannula.

What are the doses for adults?

For the granules, the dose is 10-15 g per day (divided into two doses), while for the syrup, it is 15-45 ml per day. For the rectal solution, the dose is 1 liter every 8-12 hours, to be retained for at least 30-40 minutes.

Can Lattulac EPS cause side effects?

In rare cases, it may cause abdominal cramps or excessive intestinal gas buildup (flatulence), which usually disappear within the first few days. Allergic reactions, skin rashes, itching, or hives have also been reported.

Are there interactions with other drugs?

Caution should be exercised if you are taking oral antibiotics, antacids (for stomach acidity), heart medications known as digitalis, or the antibiotic neomycin, as these may affect the efficacy or toxicity of the treatment.

Can I take this drug if I am diabetic?

Yes, the medicine can be taken by those suffering from diabetes mellitus because it contains sugars that are not absorbed at the intestinal level.

1. What Lattulac EPS is and what it is used for

Lattulac EPS contains the active substance lactulose, which belongs to a class of medicines called
anti-hyperammonaemics.
Lactulose is a sugar that, lacking a specific enzyme in the small intestine for its metabolism, reaches the colon unchanged, where it is converted by the bacterial flora into short-chain fatty acids. This leads to reduced production and increased faecal excretion of ammonia, thereby helping to reduce blood ammonia levels.
Lattulac EPS is used in the treatment of:

  • conditions involving mental confusion, altered state of consciousness, and coma due to liver failure (porto-systemic hepatic encephalopathy). These conditions are related to the accumulation of toxic substances, such as ammonia, in the brain as a result of severe liver problems;
  • chronic and degenerative liver disease, known as hepatic cirrhosis.

2. What you should know before taking Lattulac EPS

Do not take Lattulac EPS if:

  • you are allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6);
  • you have a hereditary disease that prevents you from metabolizing a sugar called galactose (galactosemia);
  • you have conditions leading to intestinal obstruction.

Warnings and precautions
Talk to your doctor or pharmacist before taking Lattulac EPS if you suffer from excessive production and accumulation of gas in the intestinal tract (meteorism). In such cases, treatment will start with the lowest possible doses, which may then be gradually increased according to your response to the medicine.
If you have carbohydrate metabolism disorders (diabetes mellitus), you may still take Lattulac EPS, as it contains sugars that are not absorbed at the intestinal level.
If you take Lattulac EPS for prolonged periods, in rare cases, you may experience loss of electrolytes.

Other medicines and Lattulac EPS
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Pay particular attention if you are taking:

  • oral medicines used to treat bacterial infections, as they may reduce the response to treatment with Lattulac EPS;
  • oral medicines used to counteract stomach acidity (antacids), as they may reduce the response to treatment with Lattulac EPS;
  • heart medicines called digitalics, as Lattulac EPS may increase the toxicity of these medicines;
  • neomycin, an antibiotic used to treat bacterial infections, as it increases the activity of Lattulac EPS.

Pregnancy and breastfeeding

1. What Lattulac EPS is and what it is used for

Lattulac EPS contains the active substance lactulose, which belongs to a class of medicines called
anti-hyperammonaemics.
Lactulose is a sugar which, lacking the specific enzyme for its metabolism in the small intestine, reaches the colon unchanged, where it is converted by the intestinal bacterial flora into short-chain fatty acids. This leads to reduced production and increased faecal excretion of ammonia, thereby lowering its blood levels.
Lattulac EPS is used in the treatment of:

  • conditions of mental confusion, altered consciousness level, and coma due to liver insufficiency (porto-systemic hepatic encephalopathy). These conditions are related to the accumulation of toxic substances, such as ammonia, in the brain as a result of severe liver disease;
  • chronic degenerative liver disease, known as hepatic cirrhosis.

Lattulac EPS, 200 g granules for rectal solution, is used when the patient is unable to take Lattulac EPS orally due to the following reasons:

  • impaired level of consciousness, coma, pre-coma, or semiconsciousness;
  • difficulty in taking Lattulac EPS orally due to high doses or its taste;
  • risk of tracheal aspiration with oral administration;
  • medical inability to take the product orally (e.g. due to endoscopic procedures or intubation).

2. What you need to know before using Lactulac EPS

The lactulose crystals contained in the graduated bag must be dissolved in lukewarm water (37°C), bringing the volume up to 1 litre, immediately before use.

Instructions for use
To facilitate the use of the medicine in a quick and hygienic manner, it is recommended to use the accessories provided in the package together with the ready-to-use Lattulac EPS bag, which serves the dual purpose of containing the active ingredient and acting as an administration device:

  • Atraumatic rectal cannula, individually packed in a heat-sealed pouch;
  • Lubricant for the rectal cannula, supplied in a heat-sealed pouch.

Preparation and administration of Lattulac EPS 200 g granules for rectal solution (1-litre bag) must be carried out as follows:

    If immediate evacuation occurs, the enema must be immediately repeated. A balloon catheter, available at pharmacies, may be used if necessary to ensure retention for the required time. The catheter should be attached to the cone of the drainage tube, replacing the rectal cannula.

Use in adults
The recommended dose is 1 litre of Lattulac EPS every 8–12 hours, to be retained in the intestine for at least 30–40 minutes.
If the patient persistently fails to retain the enema for the required time (at least 30–40 minutes), or if there are any issues with subjective tolerability (abdominal pain or significant discomfort), the 1-litre dose may be divided into two half-doses of 500 ml administered every 3–4 hours. Rectal administration should continue for 3–4 days, during which full and alert consciousness is usually restored, allowing transition to oral administration of Lattulac EPS or other medications.

If you use more Lattulac EPS than you should
