1. What is MANNITOL 20% FRESENIUS and what is it used for
MANNITOL 20% FRESENIUS is a medicine that increases the amount of urine excreted and moves water from tissues to the vascular space. The medicine reduces intracranial and intraocular pressure. It is administered intravenously.
- Indications for use:
- increased diuresis (increased urine excretion) in the prevention and treatment of oliguria (reduced urine production) in acute renal failure;
- reduction of intracranial pressure and reduction of brain edema;
- reduction of elevated intraocular pressure when it cannot be reduced by other means;
- increased excretion of toxic substances by the urinary system (so-called forced diuresis).
2. Important information before using MANNITOL 20% FRESENIUS
When not to use MANNITOL 20% FRESENIUS:
- if the patient is allergic to mannitol;
- if the patient has advanced renal failure with anuria;
- if the patient has symptoms of pulmonary congestion or pulmonary edema;
- if the patient has intracranial hemorrhage, except for hemorrhages during craniotomy (surgical opening of the skull);
- if the patient is severely dehydrated;
- if the patient develops progressive renal failure with increasing oliguria (significant reduction in urine output) and azotemia (excess nitrogen in the blood) after starting mannitol administration;
- if the patient's heart failure worsens or symptoms of pulmonary congestion increase after starting mannitol administration.
Warnings and precautions
In patients with significant renal function disorders before starting MANNITOL 20% FRESENIUS, the doctor will administer a test dose to check the body's reaction to the medicine.
- During MANNITOL 20% FRESENIUS administration, the doctor will monitor:
- sodium and potassium levels in the blood (whether there is a disturbance in fluid and electrolyte balance);
- hourly diuresis (amount of urine excreted per hour);
- whether hypovolemia (too little blood in the blood vessels) worsens;
- whether congestive heart failure (heart dysfunction characterized by edema in the legs and pulmonary edema) worsens;
- renal function.
The medicine must not be administered intramuscularly or subcutaneously, and not in combination with blood.
MANNITOL 20% FRESENIUS and other medicines
Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or plan to take.
- Caution should be exercised when using the following medicines in combination with MANNITOL 20% FRESENIUS:
- neomycin (an antibiotic used to treat fungal infections) due to the increased risk of hearing loss and kidney damage;
- kanamycin (an antibiotic used to treat infections) due to the risk of hearing loss;
- digitalis glycosides (medicines used to treat heart failure) due to the risk of digitalis toxicity, especially if the patient has low potassium levels in the blood;
- diuretic medicines, as mannitol enhances their effect;
- other diuretic medicines, including carbonic anhydrase inhibitors, as they may enhance the effect of reducing intraocular pressure.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before using this medicine.
Driving and using machines
MANNITOL 20% FRESENIUS has no or negligible influence on the ability to drive and use machines.
3. How to use MANNITOL 20% FRESENIUS
This medicine is administered only by medical personnel. The medicine must not be used by yourself. In case of doubts, consult a doctor.
Using a higher dose of MANNITOL 20% FRESENIUS than recommended
In case of using a higher dose of the medicine, inform your doctor or nurse immediately.
- Rapid administration of a large amount of mannitol may cause:
- excessive increase in fluid volume in the blood vessels;
- heart failure;
- pulmonary edema.
Using higher doses of the medicine than recommended may cause excessive loss of electrolytes, especially sodium, potassium, and chlorides. Low levels of these electrolytes may cause:
- orthostatic hypotension (decrease in blood pressure when changing position from lying to standing);
- tachycardia (rapid, abnormal heart rhythm);
- decrease in central venous pressure (due to too little blood in the blood vessels);
- disorders of nerve conduction and muscle function (muscle paralysis);
- atrophy of the gastrointestinal tract (lack of muscle contraction in the gastrointestinal tract).
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them. The following side effects may occur:
- pulmonary congestion (characteristic crackling in the lungs);
- disturbances in fluid and electrolyte balance;
- acidosis (accumulation of excessive amounts of acidic substances in the blood);
- dry mouth, increased thirst;
- excessive diuresis (excretion of large amounts of urine), urinary retention;
- edema;
- headache, dizziness;
- blurred vision;
- seizures;
- nausea, vomiting, diarrhea;
- rhinitis;
- arm pain;
- skin necrosis;
- thrombophlebitis (formation of inflammation and small blood clots, characterized by palpable hardening of the vein, redness around it, pain, and tenderness);
- chills;
- urticaria (bright red, itchy blisters on the skin);
- dehydration (excessive loss of fluid from the body);
- decrease in blood pressure;
- tachycardia (rapid, abnormal heart rhythm);
- fever;
- chest pain similar to angina (severe pain behind the sternum, radiating to the arms, jaw);
- congestive heart failure (heart dysfunction characterized by edema in the legs and pulmonary edema);
- vein pain and irritation caused by too rapid administration of the medicine.

Information intended for healthcare professionals only:
Dosage and administration
Dosage
- The rate of infusion and the amount of solution administered depend on the indication, fluid requirements, and renal function.
- The usual dose in adults is 50-200 g/day.
- In most cases, the appropriate response occurs after administration of a dose of about 100 g/day.
- The rate of administration is usually based on diuresis. The diuresis rate should be maintained at at least 30-50 ml/h.
The above guidelines are only general recommendations for the use of the medicine.
Usually, the medicine is used according to the following scheme:
Adult patients
Test dose in patients with significant oliguria or renal function disorders
The dose is: 0.2 g/kg body weight (75 ml of 20% solution). Administration of this dose over 3-5 minutes should cause diuresis at a rate of at least 30-50 ml/h. If the diuresis rate does not increase, a second test dose can be administered. Lack of the desired effect after the second dose indicates that treatment with mannitol is ineffective.
Treatment of oliguria
Maximum daily dose is about 1.5 g/kg body weight/day (about 100 g/day for a patient with a body weight of 70 kg).
Maximum infusion rate is 0.3 g/kg body weight/h (21 g/h for a patient with a body weight of 70 kg).
The medicine should not be administered again to patients with persistent oliguria.
Prevention of oliguria
To prevent acute renal failure during cardio-surgical and other surgical procedures, a dose of 50-100 g of mannitol is used.
Reduction of intracranial pressure, brain edema
To achieve maximum effect, mannitol is administered intravenously in a dose of 0.25 g/kg body weight, not more frequently than every 6-8 hours.
Reduction of intraocular pressure
A dose of 1.5-2 g/kg body weight (7.5 ml to 10 ml of 20% solution/kg body weight) can be administered over 30 minutes to achieve rapid and maximum effect.
If mannitol is used to reduce intraocular pressure before ophthalmic surgical procedures, the above dose should be administered about 1-1.5 hours before the surgical procedure.
Acceleration of excretion of toxic substances by the urinary system
The dose should be adjusted according to the patient's current diuresis and fluid requirements.
The total dose of mannitol should not exceed 200 g. Loss of water and electrolytes should be compensated.
Children
The efficacy and safety of MANNITOL 20% FRESENIUS in children under 12 years of age are not known.
Reduction of brain edema, reduction of intracranial pressure, reduction of intraocular pressure
Intravenous infusion of a dose of 1-2 g/kg body weight, administered over 60 minutes.
Oliguria
Intravenous infusion of a dose of 0.25-2 g/kg body weight, administered over 2-6 hours.
Before using the medicine, a test dose of 0.75 g/kg body weight should be administered over 3-5 minutes. If diuresis does not increase within 2 hours, the medicine should not be used.
Overdose
Rapid administration of a large amount of mannitol may cause excessive increase in fluid volume in the vascular space, heart failure, and pulmonary edema.
Using higher doses of the medicine than recommended may cause excessive loss of electrolytes, especially sodium, potassium, and chlorides. Low levels of these electrolytes may cause hypotension, tachycardia, and decrease in central venous pressure. Low potassium levels in the blood may cause disorders of nerve conduction and muscle function and atrophy of the gastrointestinal tract.
Interactions with other medicines and other types of interactions
If blood transfusion is necessary during mannitol infusion, blood and mannitol should be administered through separate veins.
Mannitol enhances the diuretic effect of diuretic medicines.
Concomitant use of mannitol with neomycin may increase ototoxicity and nephrotoxicity.
Concomitant use of mannitol with kanamycin may cause hearing loss.
Concomitant use of mannitol with digitalis glycosides may increase the risk of digitalis toxicity associated with hypokalemia.
Concomitant use of mannitol with other diuretic medicines, including carbonic anhydrase inhibitors, may enhance the effect of reducing intraocular pressure. Therefore, dose adjustment may be necessary.
Preparation of the medicine for use
Use only clear solution.
Unused medicine should not be used.
Do not use this medicine if you notice contamination, color change, or if the packaging is damaged.
Follow the principles of asepsis.
Incompatibilities
MANNITOL 20% FRESENIUS should not be mixed with the following medicines due to incompatibility:
- erythromycin, tetracycline hydrochloride, cefapirin, ofloxacin, potassium chloride.
Due to the lack of data on interactions between mannitol and other substances, mixing with other medicines should be avoided.
Storage conditions
