1 ): • For intravenous infusion preferably into a large central vein. • Prior to administration, evaluate renal, cardiac and pulmonary status, and correct fluid and electrolyte imbalances. 2 ) : • The dosage, concentration and rate of administration depend on the age, weight and condition of the patient, including fluid requirement, urinary output and concomitant therapy.
25 gram/kg administered every 6 to 8 hours as an intravenous infusion over 30 minutes. 5 to 2 grams/kg of a 15% or 20% w/v solution as a single dose administered intravenously over at least 30 minutes. 5) , Description (11) ]. 2) ]. • Do not administer OSMITROL simultaneously with blood products through the same administration set because of the possibility of pseudoagglutination or hemolysis.
Preparation 1. Tear overwrap down side at slit and remove solution container. 2. Visually inspect the container. Do not administer unless solution is clear and seal is intact. o If the outlet port protector is damaged, detached, or not present, discard container as solution path sterility may be impaired.
o Some opacity of the plastic due to moisture absorption during the sterilization process may be observed. This is normal and does not affect the solution quality or safety. The opacity will diminish gradually. 3. Check for minute leaks by squeezing inner bag firmly.
If leaks are found, discard solution as sterility may be impaired. 4. Admixing OSMITROL with other medications is not recommended. 5. Inspect OSMITROL visually for particulate matter and discoloration prior to administration. If particulates or discoloration are present, discard the bag.
6. OSMITROL solutions may crystallize when exposed to low temperature. At higher concentrations, the solutions have a greater tendency to crystallize. Inspect OSMITROL for crystals prior to administration. If crystals are visible, re-dissolve by warming the solution up to 70°C, with agitation.
Solutions should not be heated in water or in a microwave oven due to potential for product contamination or damage. Allow the solution to cool to room or body temperature before re-inspection for crystals and use. Administration 1. Suspend container from eyelet support.
2. Remove protector from outlet port at bottom of container. 3. Attach administration set. Refer to complete directions accompanying set. 4. Use administration sets with a final in-line filter because of the potential for OSMITROL crystals to form.
6 ADVERSE REACTIONS The following adverse reactions from voluntary reports or clinical studies have been reported with OSMITROL. Because many of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
• Hypersensitivity reactions : cardiac arrest, anaphylaxis, hypotension, dyspnea, hypertension, pyrexia, chills, sweating, cough, musculoskeletal stiffness, myalgia, urticarial/rash, pruritus, generalized pain, discomfort, nausea, vomiting, and headache.
6) ] • Cardiac and Respiratory Disorders : congestive cardiac failure, pulmonary edema, palpitations • Gastrointestinal Disorders : thirst, dry mouth • General Disorders : asthenia, malaise The most common adverse reactions are hypersensitivity reactions, renal failure, CNS toxicity, hypo/hypervolemia, hypo/hypernatremia, hypo/hyperkalemia, and infusion site reactions.

5 WARNINGS AND PRECAUTIONS • Hypersensitivity Reactions, including anaphylaxis : Stop infusion immediately if hypersensitivity reactions develop. 1 ) • Renal Complications Including Renal Failure : Risk factors include pre-existing renal failure, concomitant use of nephrotoxic drugs or other diuretics.
Avoid use of nephrotoxic drugs. Discontinue OSMITROL if renal function worsens. 6 ) • Central Nervous System (CNS) Toxicity : Confusion, lethargy and coma may occur during or after infusion. Concomitant neurotoxic drugs may potentiate toxicity.
Avoid use of neurotoxic drugs. Discontinue OSMITROL if CNS toxicity develops. 3 ) • Fluid and Electrolyte Imbalances, Hyperosmolarity : Hypervolemia may exacerbate congestive heart failure, hyponatremia can lead to encephalopathy; hypo/hyperkalemia can result in cardiac adverse reactions in sensitive patients.
Discontinue OSMITROL if fluid and/or electrolyte imbalances occur. 4 ) • Monitoring/Laboratory Tests : Monitor fluid and electrolytes, serum osmolarity and renal, cardiac and pulmonary function. Discontinue if toxicity develops. 5 ) • Infusion Site Reactions : May include irritation and inflammation, as well as severe reactions (compartment syndrome) when associated with extravasation.
6 ) • Interference with Laboratory Tests : High concentrations of mannitol may cause false low results of inorganic phosphorus blood concentrations. Mannitol may produce false positive results for blood ethylene glycol. 1 Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis, hypotension and dyspnea resulting in cardiac arrest and death have been reported with OSMITROL [see Adverse Reactions (6) ].
Stop the infusion immediately if signs or symptoms of a suspected hypersensitivity reaction develop. Initiate appropriate therapeutic countermeasures as clinically indicated. 2 Renal Complications Including Renal Failure Renal complications, including irreversible renal failure have been reported in patients receiving mannitol.
5) ] • Active intracranial bleeding except during craniotomy • Known hypersensitivity to mannitol. 1 ) • Anuria. 2 ) • Severe hypovolemia. 4 ) • Pre-existing severe pulmonary vascular congestion or pulmonary edema. 5 ) • Active intracranial bleeding except during craniotomy.

5. To prevent air embolism, use a non-vented infusion set or close the vent on a vented set, avoid multiple connections, do not connect flexible containers in series, fully evacuate residual gas in the container prior to administration, do not pressurize the flexible container to increase flow rates, and if administration is controlled by a pumping device, turn off pump before the container runs dry.
6. For single use only; discard unused portion. 2 Recommended Dosage Prior to administration of OSMITROL, evaluate renal, cardiac and pulmonary status of the patient and correct fluid and electrolyte imbalances. The total dosage, concentration, and rate of administration depend on the age, weight, and condition of the patient being treated, including fluid requirement, electrolyte balance, serum osmolality, urinary output, and concomitant therapy.
The following outline of administration and dosage is only a general guide to therapy. 25 gram/kg given intravenously as an intravenous infusion over 30 minutes which may be repeated every six to eight hours. During and following OSMITROL infusion, monitor fluid and electrolytes, serum osmolarity, and renal, cardiac and pulmonary function.
5) ] . 5 to 10 mL/kg) or as a 15% w/v solution (10 to 13 mL/kg) as a single dose administered intravenously over at least 30 minutes. When used preoperatively, administer OSMITROL sixty to ninety minutes before surgery to achieve maximal reduction of intraocular pressure before operation.
Reversible, oliguric acute kidney injury (AKI) has occurred in patients with normal pretreatment renal function who received large intravenous doses of mannitol. Although the osmotic nephrosis associated with mannitol administration is in principle reversible, osmotic nephrosis in general is known to potentially proceed chronic or even end-stage renal failure.
Monitor renal function closely, including signs of urine output reduction, during OSMITROL infusion. Patients with pre-existing renal disease, patients with conditions that put them at high risk for renal failure, or those receiving potentially nephrotoxic drugs or other diuretics, are at increased risk of renal failure following administration of OSMITROL.
2 )]. Patients with oliguric AKI who subsequently develop anuria while receiving mannitol are at risk of congestive heart failure, pulmonary edema, hypertensive crisis, coma and death. During and following OSMITROL infusion for the reduction in intracranial pressure, monitor the patient clinically and laboratory tests for changes in fluid and electrolyte status.
Discontinue OSMITROL if renal function worsens. 5) ]. 4) ]. At high concentrations, mannitol may cross the blood brain barrier and interfere with the ability of the brain to maintain the pH of the cerebrospinal fluid especially in the presence of acidosis.
In patients with preexisting compromise of the blood brain barrier, the risk of increasing cerebral edema (general and focal) associated with repeated or continued use of OSMITROL must be individually weighed against the expected benefits.
A rebound increase of intracranial pressure may occur several hours after the infusion. Patients with a compromised blood brain barrier are at increased risk. , aminoglycosides) with OSMITROL may potentiate neurotoxicity. 3) ]. During and following OSMITROL infusion for the reduction in intracranial pressure, monitor the patient clinically and laboratory tests for changes in fluid and electrolyte status.
5) ]. 4 Fluid and Electrolyte Imbalances, Hyperosmolarity Depending on dosage and duration, administration of OSMITROL may result in hypervolemia leading to or exacerbating existing congestive heart failure. Accumulation of mannitol due to insufficient renal excretion increases the risk of hypervolemia.
Mannitol-induced osmotic diuresis may cause or worsen dehydration/hypovolemia and hemoconcentration. Administration of OSMITROL may also cause hyperosmolarity [see Description (11) ]. Depending on dosage and duration of administration, electrolyte and acid/base imbalances may also result from transcellular shifts in water and electrolytes, osmotic diuresis and/or other mechanisms.
Such imbalances may be severe and potentially fatal. Imbalances that may result from OSMITROL administration include: • Hypernatremia, dehydration and hemoconcentration • Hyponatremia, which can lead to headache, nausea, seizures, lethargy, coma, cerebral edema, and death.
Acute symptomatic hyponatremic encephalopathy is considered a medical emergency. • Hypo/hyperkalemia. 4) ]. 4) ]. 5) ]. 5 Monitoring/Laboratory Tests During and following OSMITROL infusion for the reduction in intracranial pressure, monitor: • serum osmolarity, serum electrolytes (including sodium, potassium, calcium and phosphate) and acid base balance, • the osmol gap • signs of hypo- or hypervolemia, including urine output • renal, cardiac and pulmonary function • intracranial pressure Discontinue OSMITROL if renal, cardiac, or pulmonary status worsens or CNS toxicity develops [see Contraindications (4) ].
6 Infusion Site Reactions The infusion of hypertonic solutions through a peripheral vein, including OSMITROL at a concentration of 10% w/v or greater, may result in peripheral venous irritation, including phlebitis. Other severe infusion site reactions, such as compartment syndrome and swelling associated with extravasation, can occur with administration of OSMITROL [see Adverse Reactions (6) ].
