Market Leader for a Reason

Use of DIPRIVAN has been associated with both fatal and life-threatening anaphylactic and anaphylactoid reactions. Clinical features of anaphylaxis, including angioedema, bronchospasm, erythema, and hypotension occur rarely following DIPRIVAN administration.

Strict aseptic technique must always be maintained during handling. DIPRIVAN is a single access parenteral product (single patient infusion vial) which contains 0.005% disodium edetate (EDTA) to inhibit the rate of growth of microorganisms, for up to 12 hours, in the event of accidental extrinsic contamination. However, DIPRIVAN can still support the growth of microorganisms, as it is not an antimicrobially preserved product under USP standards. Failure to use aseptic technique when handling DIPRIVAN was associated with microbial contamination of the product and with fever, infection, sepsis, other life-threatening illness, and death. Do not use if contamination is suspected. Discard unused drug product as directed within the required time limits. There have been reports, in the literature and other public sources, of the transmission of bloodborne pathogens (such as Hepatitis B, Hepatitis C, and HIV) from unsafe injection practices, and use of propofol vials intended for single use on multiple persons. A DIPRIVAN vial is never to be accessed more than once or used on more than one person.

DIPRIVAN has no vagolytic activity. Reports of bradycardia, asystole, and rarely, cardiac arrest have been associated with DIPRIVAN. Pediatric patients are susceptible to this effect, particularly when fentanyl is given concomitantly.

DIPRIVAN should not be coadministered through the same IV catheter with blood or plasma because compatibility has not been established.

For general anesthesia or monitored anesthesia care (MAC) sedation, DIPRIVAN should be administered only by persons trained in the administration of general anesthesia and not involved in the conduct of the surgical/diagnostic procedure. Sedated patients should be continuously monitored, and facilities for maintenance of a patent airway, providing artificial ventilation, administering supplemental oxygen, and instituting cardiovascular resuscitation must be immediately available. Patients should be continuously monitored for early signs of hypotension, apnea, airway obstruction, and/or oxygen desaturation. These cardiorespiratory effects are more likely to occur following rapid bolus administration, especially in the elderly, debilitated, or ASA-PS III or IV patients.

Administer DIPRIVAN with caution in patients with disorders of lipid metabolism such as primary hyperlipoproteinemia, diabetic hyperlipemia, and pancreatitis.

Very rarely the use of DIPRIVAN may be associated with the development of a period of postoperative unconsciousness which may be accompanied by an increase in muscle tone.

When DIPRIVAN is administered to an epileptic patient, there is a risk of seizure during the recovery phase.

Attention should be paid to minimize pain on administration of DIPRIVAN.

Venous sequelae, i.e., phlebitis or thrombosis, have been reported rarely (less than 1%).

Perioperative myoclonia, rarely including convulsions and opisthotonos, has occurred in association with DIPRIVAN administration.

Rarely, cases of unexplained postoperative pancreatitis (requiring hospital admission) have been reported after anesthesia in which DIPRIVAN was one of the induction agents used.

For sedation of intubated, mechanically ventilated patients in the Intensive Care Unit (ICU), DIPRIVAN should be administered only by persons skilled in the management of critically ill patients and trained in cardiovascular resuscitation and airway management. Patients should be continuously monitored for early signs of significant hypotension and/or cardiovascular depression, which may be profound.

Abrupt discontinuation of DIPRIVAN prior to weaning or for daily evaluation of sedation levels should be avoided. This may result in rapid awakening with associated anxiety, agitation, and resistance to mechanical ventilation. In pediatric patients, abrupt discontinuation of DIPRIVAN following prolonged infusion may result in flushing of the hands and feet, agitation, tremulousness and hyperirritability. Increased incidences of bradycardia, agitation, and jitteriness have also been observed.

For both adult and pediatric ICU sedation, DIPRIVAN infusion has been associated with Propofol Infusion Syndrome, that have resulted in death. The syndrome is characterized by severe metabolic acidosis, hyperkalemia, lipemia, rhabdomyolysis, hepatomegaly, renal failure, ECG changes and/or cardiac failure.

Since DIPRIVAN is formulated in an oil-in-water emulsion, elevations in serum triglycerides may occur when DIPRIVAN is administered for extended periods of time. Patients at risk of hyperlipidemia should be monitored for increases in serum triglycerides or serum turbidity.

EDTA is a strong chelator of trace metals – including zinc. DIPRIVAN should not be infused for longer than 5 days without providing a drug holiday to safely replace estimated or measured urine zinc losses. At high doses (2 grams to 3 grams per day), EDTA has been reported, on rare occasions, to be toxic to the renal tubules. Monitor patients at risk for renal impairment.

There have been rare reports of pulmonary edema in temporal relationship to the administration of DIPRIVAN, although a causal relationship is unknown.

Neurosurgical Anesthesia: When DIPRIVAN is used in patients with increased intracranial pressure or impaired cerebral circulation, significant decreases in mean arterial pressure should be avoided because of the resultant decrease in cerebral perfusion pressure.

Cardiac Anesthesia: Slower rates of administration should be utilized in premedicated patients, geriatric patients, patients with recent fluid shifts, and patients who are hemodynamically unstable.

Pediatric Neurotoxicity: Published animal studies demonstrate that the administration of anesthetic and sedation drugs that block NMDA receptors and/or potentiate GABA activity increase neuronal apoptosis in the developing brain and result in long-term cognitive deficits when used for longer than 3 hours. The clinical significance of these findings is unclear.

Adverse reactions reported with an incidence greater than 1% were: bradycardia, arrhythmia, tachycardia, hypotension, decreased cardiac output, hypertension, movement, apnea, respiratory acidosis during weaning, rash, pruritus, burning/stinging or pain at injection site, and hyperlipemia.

DIPRIVAN is not recommended for obstetrics, including Cesarean section deliveries. DIPRIVAN crosses the placenta, and as with other general anesthetic agents, the administration of DIPRIVAN may be associated with neonatal depression.

DIPRIVAN is not recommended for use in nursing mothers because Propofol has been reported to be excreted in human milk, and the effects of oral absorption of small amounts of propofol are not known.

Indications and Usage
DIPRIVAN® (Propofol), Injectable Emulsion, USP is an intravenous general anesthetic and sedation drug for use in adults for initiation and maintenance of Monitored Anesthesia Care (MAC) sedation, combined sedation and regional anesthesia, and Intensive Care Unit (ICU) sedation of intubated, mechanically ventilated patients. DIPRIVAN is also indicated for induction of general anesthesia for patients greater than or equal to 3 years of age and for maintenance of general anesthesia for patients greater than or equal to 2 months of age.
