Warnings and precautions
If during the use of Olopeg for bowel cleansing, the patient experiences sudden abdominal pain or rectal bleeding, they should contact a doctor or seek medical help immediately.
In patients with water and electrolyte balance disorders (with symptoms such as edema, dyspnea, increasing fatigue, dehydration, heart weakness), Olopeg should be discontinued, and electrolyte levels should be measured and appropriate measures taken if necessary.
The product contains potassium. Warning regarding dosing in patients with limited kidney function or those on a low-potassium diet: The medicine contains 1.26 mmol (or 49 mg) of potassium per dose (125 ml of ready-to-drink solution), which should be taken into account in patients with reduced kidney function and in patients controlling potassium intake in their diet.
The product contains sodium. Warning regarding dosing in patients on a low-sodium diet: The medicine contains 186 mg of sodium (the main component of table salt) in each dose unit (125 ml of ready-to-drink solution). This corresponds to 9.3% of the maximum recommended daily sodium intake in the diet for adults.
In diabetic patients, there is no need to count additional bread units.
In patients with a tendency to water and electrolyte balance disorders (e.g., elderly patients, patients with liver or kidney function disorders, patients taking diuretics), Olopeg can be used on the explicit recommendation of a doctor with special caution. In case of diarrhea in these patients, water and electrolyte balance control is recommended.
Elderly patients should use Olopeg with special caution, as they are usually more prone to adverse reactions to medicines.
This should be particularly remembered in case of diarrhea and water and electrolyte balance disorders.
In patients with reflux esophagitis or heart rhythm disorders (conduction disorders between the sinus node and the atrium, sick sinus syndrome), Olopeg can be used only under medical supervision.
Children
There have been no sufficient studies on the use of the medicine in children and adolescents, therefore, Olopeg should not be used in children and adolescents under 18 years of age.
Pregnancy and breastfeeding
If the patient is pregnant or breastfeeding, suspects that she may be pregnant, or plans to have a child, she should consult a doctor or pharmacist before using this medicine.
There have been no sufficient studies on the use of the medicine during pregnancy, therefore, Olopeg can be used in pregnant women only if necessary.
There have been no sufficient studies on the use of the medicine during breastfeeding, therefore, Olopeg can be used in breastfeeding women only if necessary.
Driving and using machines
The medicine has no influence or has a negligible influence on the ability to drive and use machines.
The solution does not containsodium sulfate or sugar.
Olopeg and other medicines
The patient should tell their doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
During diagnostic tests performed using enzymatic methods (e.g., ELISA), there may be an interaction between polyethylene glycol and enzymes.
Interactions between Olopeg and other medicines used during the treatment of constipation
There are no clinical reports of interactions with other medicines. However, macrogol increases the solubility of substances soluble in alcohol and relatively poorly soluble in water. Therefore, there is a theoretical possibility that the absorption of such medicines may be temporarily reduced. Therefore, it is recommended to maintain a break of at least two hours between taking Olopeg and other medicines.
Interactions between Olopeg and other medicines used during bowel cleansing
If the patient has taken other medicines a few hours before or during the use of Olopeg, there may be a flushing of these medicines from the stomach and intestines or a reduction in their absorption or complete blockade of absorption. This applies especially to medicines with delayed release of active substances. If it is necessary to administer another medicine with a life-saving indication shortly before or during the use of Olopeg, it may be necessary to abandon oral administration of this medicine and use an intravenous or intramuscular form.
3. How to use Olopeg
This medicine should always be used as directed by a doctor or pharmacist. In case of doubts, consult a doctor or pharmacist.
Before drinking, Olopeg should be diluted in water according to the following scheme.
Symptomatic treatment of constipation
The medicine is used as an aid, with a healthy lifestyle and diet maintained.
Adults
2-3 times a day, 25 ml of Olopeg should be diluted in 100 ml of water (a total of 125 ml of solution per dose), and then drunk.
Elderly patients
Initially, once a day, 25 ml of Olopeg should be diluted in 100 ml of water (resulting in 125 ml of solution), and then drunk.
As with all laxatives, long-term use of Olopeg is not recommended. Olopeg should not be used for more than 2 weeks. If necessary, it can be used again.
Bowel cleansing before diagnostic examination
To prepare one liter of solution, 200 ml of Olopeg should be added to 800 ml of water.
To completely cleanse the bowel, 3-4 liters of solution should be drunk.
The solution should be drunk in portions of 200-300 ml every 10 minutes until the stool is clear or the patient has taken 3 liters (or a maximum of 4 liters) of the solution.
The bowel cleansing solution is usually taken about 4 hours before the start of the examination.
The patient may also need to drink the required amount of solution the previous evening or part of the solution the previous evening and the rest in the morning on the day of the examination.
For 2-3 hours before the administration of Olopeg and until the examination is performed, no solid food should be taken.
If gastrointestinal symptoms occur, the solution prepared with Olopeg should be drunk more slowly or its administration should be stopped until these symptoms disappear.
Using a higher dose of Olopeg than recommended
In case of symptoms indicating an overdose, such as severe pain, bloating, or severe diarrhea, consult a doctor.
Missing a dose of Olopeg
If the amount of solution drunk is significantly less than the recommended dose, bowel cleansing may be insufficient, which may make it impossible to perform the planned examination. The recommended dosage by the doctor or the instructions in the patient leaflet should be strictly followed.
