This medication is solely for diagnostic use.

Barilux belongs to the group of medications known as radiological contrast agents for X-rays containing barium sulfate without suspending agents, classified within the ATC (anatomical therapeutic chemical classification) in the pharmacotherapeutic group VO8BA01.

Barilux is a radio-opaque diagnostic agent used to intensify contrast during visualization of the gastrointestinal tract through certain radiological techniques:

• Oral use:

• Rectal use (administered through an enema in the intestine):for double-contrast X-ray explorations of the lower gastrointestinal tract (rectum, sigma, and colon), as a diagnostic aid for pathologies in these organs.

Barilux is indicated in pediatric populations for opacification of the upper and lower gastrointestinal tract only in simple X-ray contrast explorations as a diagnostic aid for pathologies in these organs.

Do not take Barilux:

• if you are allergic (hypersensitive) to the active ingredient or any of the other components of Barilux (oral and rectal routes).
• if you have an inflammation of the abdominal cavity walls (irritated peritoneum) (oral and rectal routes).
• if you have a complete obstruction of the gastrointestinal tract (only for oral use).
• if you have a narrowing of the pylorus (pyloric stenosis) (only for oral use).
• if you have or suspect a perforation of the gastrointestinal tract (oral and rectal routes).
• if you have a postoperative gastrointestinal suture dehiscence (suture opening) (only for oral use).
• if you have or suspect an intestinal perforation (only for oral use).
• if you have intestinal fistulas (oral and rectal routes).
• if you have tracheoesophageal or bronchoesophageal fistulas (only for oral use).
• if you have recent injuries or chemical burns in the gastrointestinal tract (oral and rectal routes).
• if you have insufficient blood flow (ischemia) to the intestinal wall (oral and rectal routes).
• if you have a condition called "necrotizing enterocolitis" (oral and rectal routes).
• if you are about to undergo gastrointestinal tract surgery (oral and rectal routes)
• within 7 days after an endoscopic resection (oral and rectal routes).
• within 4 weeks after concurrent radiation therapy (oral and rectal routes).

Be especially careful with Barilux:

• If you are an elderly person with diseases, mainly cardiovascular, as the test may be stressful for you.
• If you have high-grade stenosis, especially in the distal parts of the stomach or conditions with a high risk of perforation, such as fistulas and gastrointestinal carcinomas, inflammatory bowel disease, diverticulitis, diverticulosis, and amebiasis, a thorough benefit-risk assessment is necessary.

During the radiological examination, the penetration of barium sulfate into areas such as tissues, vascular space, and body cavities or respiratory tracts should be prevented to avoid potentially severe adverse reactions.

You should also ensure adequate hydration after the procedure to avoid severe constipation.

To avoid potentially severe adverse reactions, during the diagnostic process, the penetration of barium sulfate into areas outside the gastrointestinal tract (parenteral) such as tissues, vascular space, and body cavities or respiratory tracts should be prevented.

In the event of massive aspiration of the product, intravascular penetration, or perforation, immediate specialized medical intervention, intensive care, or surgery is necessary.

During the radiological examination, barium sulfate may accumulate in the colon diverticula, potentially favoring or worsening infectious processes in this location.

In the case of barium sulfate coprolite formation (bariolites) due to the thickening of barium sulfate, laxatives and/or saline purgatives (with salts or minerals) are recommended.

Use of other medications:

Inform your doctor or pharmacist if you are using or have recently used other medications, including those purchased without a prescription.

Certain medications may interact with Barilux, and in these cases, it may be necessary to change the dose or discontinue treatment with one of the medications. It is especially important to inform your doctor if you are using any of the following medications:

• Medications that reduce intestinal peristalsis (contractions in the form of waves along the intestine): Taking these medications may cause thickening of the barium sulfate suspension and increase the risk of constipation.

Use of Barilux with food and beverages:

Pregnancy and breastfeeding:

Consult your doctor or pharmacist before using any medication.

The use of barium contrast agents in pregnant women has not been sufficiently demonstrated to be safe. Radiological examinations should not be performed in pregnant women unless strictly necessary or when the benefit to the mother outweighs the risk to the fetus. In any case, given the teratogenic effects of radiation exposure during pregnancy, regardless of the use or non-use of a contrast agent, the benefit of the radiological examination should be carefully evaluated.

The safety of Barilux in women breastfeeding their children has not been investigated. Contrast agents are eliminated through breast milk in minimal amounts. No damage to the infant is expected, and your doctor will evaluate the benefit-risk before performing the examination.

The use of Barilux is not contraindicated during breastfeeding

Driving and operating machines:

Barilux does not affect driving, handling tools, or operating machines.

Important information about some components of Barilux:

Patients with low-sodium diets should note that this medication contains 4,152 – 5,072 mg (180.8 – 220.8 mmol) of sodium per 800 g dose of Barilux.

Follow exactly the administration instructions for Barilux indicated by your doctor. Consult your doctor or pharmacist if you have any doubts.

Medical staff will administer Barilux orally, or rectally (via enema).

Your doctor will determine the correct amount and administration schedule of the product required for your radiographic examination, depending on your age, weight, and the technique to be used.

In infants and children, the dose will be adjusted as needed by the doctor based on age, body weight, and the specific pediatric radiodiagnostic technique.

For elderly patients, there are no special dosage recommendations.

Consult your doctor if you wish to clarify the procedure for the examination. It is essential to follow your doctor's instructions once the examination is completed.

Patient Preparation

You should drink plenty of water after the examination to reduce the risk of constipation.

Patient Preparation for the Use of Barium Contrast via Oral Route:

Patient Preparation for X-ray Examination of the Stomach:

If excessive stomach acid (gastric acid) is observed in the fasting state, it is recommended, to the extent possible, to aspirate the gastric secretion or perform the examination on another day (in the morning, as early as possible).

Some professionals use acid secretion inhibitors (which reduce the amount of acid produced in the stomach) before performing the X-ray examination, with the aim of increasing the adherence of the contrast medium to the stomach walls. The test result improves if an additional antispasmodic is administered intravenously or intramuscularly, which reduces stomach tone, decreases peristalsis, and delays stomach evacuation.

To extend the different regions of the stomach, it is recommended to administer a medication with a carbon dioxide-forming effect simultaneously.

Patient Preparation for X-ray Examination via Bifasic Enteroclisis Technique:

Your doctor may administer an additional antispasmodic intravenously or intramuscularly to reduce intestinal tone, decrease peristalsis (intestinal muscle wave movement), and delay contrast evacuation, with the aim of improving the test result and patient acceptance.

Patient Preparation for Pediatric Use:

Newborns (neonates) do not need to be fasting. For children aged 1-24 months, they should be fasting for 4 hours before the test, 6 hours for children aged 2-4 years, and 8 hours for children aged 4-14 years, although in the latter case, they may take a small amount of water up to 3 hours before the study.

In young children, it is recommended not to provide the last meal to facilitate the ingestion of the contrast.

Patient Preparation for the Use of Barium Contrast via Rectal Route

To obtain an accurate X-ray examination of the large intestine, it is essential to perform a complete colon cleansing and eliminate mucosities. In this case, it is recommended to administer laxatives of habitual use indicated especially for radiological preparation the day before the test. From this moment on, the patient should take abundant liquid (approximately 2-3 liters), but only in the form of tea, water, vegetable soup, fruit juice, etc. Milk and alcohol should be avoided.

If necessary, a cleansing enema may be administered on the day of the radiological test to achieve a deep cleansing of the large intestine. At this point, the large intestine should be free of residues that affect the development of the radiological examination.

It is possible to administer acid secretion inhibitors before the test to increase the adherence of the contrast medium to the intestinal walls. The additional administration of an antispasmodic intravenously or intramuscularly leads to a marked hypotonia (muscle tone decrease) of the entire colon, which significantly improves the test result and patient acceptance.

Patients with Liver Insufficiency:

No dose adjustment is necessary (see section 2: Be careful with Barilux)

Patients with Renal Insufficiency:

No dose adjustment is necessary (see section 2: Be careful with Barilux)

If You Take More Barilux Than You Should

In rare cases, repeated administration of barium sulfate suspensions may cause stomach spasms and diarrhea. These reactions are transient and not considered serious.

In examinations where high doses of barium enema are administered, it may cause an alteration of the electrolyte balance in the blood due to the large amount of water retained by the contrast. In such cases, it is possible to reduce the risk by adding sodium chloride to the enema liquid. The electrolyte balance in the blood is restored through appropriate infusion therapy.

In case of overdose or accidental ingestion, consult the Toxicological Information Service. Phone 91.562.04.20.

If You Forget to Take Barilux

Do not take a double dose to compensate for the missed doses.
