1. What is Oponaf and what is it used for
Oponaf belongs to a group of medicines called oral osmotic laxatives.
Oponaf is indicated:
- For the treatment of chronic habitual constipation.
- As part of the treatment of certain symptoms of portosystemic encephalopathy, which is a consequence of severe liver disease.
2. What you need to know before taking Oponaf
Chronic constipation should be treated, as a first measure, through a high-fiber diet, sufficient fluid intake, or physical exercise. If there is no improvement 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 interfere with the normal functioning of the defecation reflex, so it is recommended to treat constipation with adequate hygiene and dietary measures.
The use of laxatives during prolonged periods should be avoided.
Do not take Oponaf
- if you are allergic (hypersensitive) to lactitol;
- if you have intestinal obstruction or there is suspicion of organic lesions in the digestive tract;
- if there is unjustified 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 baby with hereditary autosomal recessive fructose intolerance;
- if you have a pre-existing electrolyte imbalance in your serum.
Warnings and precautions
- In elderly, debilitated, or dehydrated patients, or those with hypokalemia (low potassium levels in the blood), your doctor should regularly monitor the blood electrolyte levels, especially in prolonged treatments;
- If you are to undergo any internal examination of the intestine, you should consult your doctor;
- In cases of ileostomy or colostomy (opening from the ileum or colon to the outside), the administration of Oponaf is not recommended;
- In cases of particularly resistant constipation, you should consult your doctor;
- If nausea occurs, it is recommended to take Oponaf during meals;
- In babies, Oponaf should only be used after the doctor's recommendation.
Taking Oponaf with other medicines
Tell your doctor or pharmacist if you are using or have recently used any other medicines, including those obtained without a prescription.
Certain medicines may interact with Oponaf; in these cases, it may be necessary to change the dose or interrupt treatment with one of them.
It is important that you inform your doctor if you are taking or have recently taken any of the following medicines:
- Antacids or neomycin (antibiotic) should not be administered together with Oponaf in the treatment of cirrhosis with hepatic encephalopathy, as these medicines may interfere with its mechanism of action.
- Thiazide diuretics (medicines used to increase urine elimination).
- Corticosteroids (anti-inflammatory and antiallergic medicines).
- Carbenoxolone (gastric mucosa protector and anti-inflammatory).
- Amphotericin B (medicine for the treatment of fungal infections).
- Mesalazine (anti-inflammatory medicine).
Pregnancy and breastfeeding
Consult your doctor or pharmacist before using any medicine.
Oponaf should not be used during the first trimester of pregnancy unless your doctor recommends it.
Although it has not been studied whether lactitol passes into breast milk, the use of Oponaf is considered safe for breastfeeding mothers.
Driving and using machines
Oponaf does not affect the ability to drive vehicles or use machinery.
Oponaf contains lactitol

3. How to take Oponaf
Follow exactly the administration instructions of Oponaf indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.
Constipation
Treatment with Oponaf should be adapted individually, in order to achieve a daily bowel movement.
Oponaf is administered orally in a single daily dose, in the morning or at night, preferably mixed with food or drink, and taking 1-2 glasses of liquid during the meal. The patient should choose between taking the medicine in the morning or at night, according to their response, since the laxative effect occurs mostly a few hours after intake.
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 guideline may be the following:
- from 1 to 6 years: 2.5 to 5 g of powder/day (1/4 to 1/2 sachet)
- from 6 to 12 years: 5 to 10 g of powder/day (1/2 to 1 sachet)
- from 12 to 16 years: 10 to 20 g of powder/day (1 to 2 sachets)
The intake of Oponaf by children should be supervised by an adult and the doctor's instructions should be strictly followed.
Adults (including elderly patients): Oponaf is administered orally, although in hospitalized patients it can also be administered through a nasogastric tube or retention enema via a rectal balloon catheter, according to the doctor's instructions.
The initial daily dose should be 2 sachets (20 g of lactitol) in a single intake. After a few days, a daily dose of 1 sachet (10 g) may be sufficient for many patients.
In case the initial dose is not effective, a maximum dose of 3 sachets (30 g/day) may be administered.
Hepatic encephalopathy
Treatment with Oponaf should be adapted to each individual. It is important to follow the doctor's instructions. The initial dose for the treatment of adults is 0.5 to 0.7 g/kg of body weight per day. The daily dose should be divided into 3 intakes, with meals, drinking 1-2 glasses of liquid during the meal.
The indicated dose may vary until two soft stools per day are achieved, depending on the severity of the disease and the response to treatment.
If you think the effect of Oponaf is too strong or too weak, tell your doctor or pharmacist.
Your doctor will indicate the duration of your treatment with Oponaf. Do not stop treatment before the indicated time, as irregular use or premature interruption of treatment carries the risk of relapse.
If you take more Oponaf than you should
If you have taken more Oponaf than you should, consult your doctor or pharmacist immediately.
The sign of overdose with Oponaf is diarrhea, which may disappear by reducing the dose. If diarrhea persists, consult your doctor.
