Oponaf belongs to a group of medications known as oral osmotic laxatives.

Oponaf is indicated for:

• The treatment of chronic habitual constipation.
• As part of the treatment of some symptoms of portal-systemic encephalopathy, which is a consequence of a severe liver disease.

Chronic constipation should be treated, as a first measure, with a diet rich in fiber, sufficient liquid intake, or physical exercise. If no improvement is seen with these measures, your doctor may recommend the use of Oponaf.

Especially in children, it should be taken into account that prolonged treatment with laxatives can impede the normal functioning of the defecation reflex, so it is recommended to treat constipation with appropriate hygiene and dietary measures.

Prolonged use of laxatives should be avoided.

Do not take Oponaf

• if you are allergic (hypersensitive) to lactitol;
• if you have intestinal obstruction or suspicion of organic lesions in the digestive tract;
• if you have unexplained abdominal pain or rectal bleeding;
• if you are following a galactose-free diet;
• in case of fecal stasis (prolonged retention), which should be treated previously by other means;
• if you have galactosemia;
• if you are breastfeeding a lactant with hereditary autosomal recessive fructose intolerance;
• if you have a pre-existing electrolyte imbalance in your serum.

Warnings and precautions

• in elderly patients, debilitated or dehydrated or with hypopotasemia (low potassium levels in blood), your doctor should regularly monitor blood electrolyte levels, especially in prolonged treatments;
• if you need to undergo any internal examination of the intestine, consult your doctor;
• in cases of ileostomy or colostomy (opening from the ileum or colon to the outside) Oponaf administration is not recommended;
• in case of particularly resistant constipation, consult your doctor;
• if nausea occurs, it is recommended to take Oponaf during meals;
• in babies, Oponaf should only be used after doctor's recommendation.

Administration of Oponaf with other medications

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

Certain medications may interact with Oponaf; in these cases, it may be necessary to change the dose or discontinue treatment with one of them.

It is essential to inform your doctor if you are taking or have recently taken any of the following medications:

• Anti-acids or neomycin (antibiotic) should not be administered concurrently with Oponaf in cirrhosis with hepatic encephalopathy treatments, as these medications can interfere with its mechanism of action.
• Thiazide diuretics (medications used to increase urine elimination).
• Corticosteroids (anti-inflammatory and antiallergic medications).
• Carbenoxolone (gastric mucosa protector and anti-inflammatory).
• Ampicillin B (medication for fungal infections).
• Mesalazine (anti-inflammatory medication).

Pregnancy and lactation

Consult your doctor or pharmacist before using any medication.

Oponaf should not be used during the first trimester of pregnancy unless your doctor recommends otherwise.

Constipation

Oponaf treatment should be adapted individually to achieve a daily bowel movement.

Oponaf is administered orally in a single daily dose, either in the morning or at night, preferably mixed with food or drink and taking 1-2 glasses of liquid during meals. The patient should choose between taking the medication in the morning or at night, according to their response, as the laxative effect occurs mainly a few hours after taking it.

The first laxative response may not appear until the second or third day of treatment.

Use in children: The initial daily dose is 0.25 g/kg of body weight per day; a general schedule can be as follows:

• 1 to 6 years: 2.5 to 5 g of powder/day (¼-½ scoop)
• 6 to 12 years: 5 to 10 g of powder/day (½-1 scoop)
• 12 to 16 years: 10 to 20 g of powder/day (1-2 scoops)

Oponaf intake by children should be supervised by an adult and the doctor's instructions should be followed strictly.

Adults (including elderly patients): Oponaf is administered orally, although in hospitalized patients it can also be administered via nasogastric tube or rectal balloon catheter enema, as indicated by the doctor.

The initial daily dose should be 2 scoops (20 g of lactitol) in a single dose. After a few days, a daily dose of 1 scoop (10 g) may be sufficient for many patients.

If the initial dose is not effective, a maximum dose of 3 scoops (30 g/day) may be administered.

Hepatic encephalopathy:

Oponaf treatment should be adapted to each individual. It is essential to follow the doctor's instructions. The initial dose for adult treatment is 0.5 to 0.7 g/kg of body weight per day. The daily dose should be divided into 3 doses, taken with meals, drinking 1-2 glasses of liquid during meals.

The indicated dose may vary to achieve 2 soft bowel movements per day, depending on the severity of the disease and the response to treatment.

If you estimate that Oponaf's action is too strong or too weak, inform your doctor or pharmacist.

Your doctor will indicate the duration of your Oponaf treatment. Do not discontinue treatment before the indicated time, as irregular use or premature interruption of treatment may lead to relapse.
