Use: Labeled Indications

Intensive care unit sedation: Sedation of initially-intubated and mechanically-ventilated patients during treatment in an intensive care setting

Procedural sedation: Procedural sedation prior to and/or during awake fiberoptic intubation; sedation prior to and/or during surgical or other procedures of nonintubated patients

Off Label Uses

Sedation during awake craniotomy

Data from controlled studies indicate that dexmedetomidine can be used successfully to provide sedation during awake craniotomy and may help reduce length of stay as well as the need for other perioperative pharmacological interventions. Additional trials may be necessary to further define the role of dexmedetomidine in this condition.

Additional Off-Label Uses

Treatment of shivering

Contraindications

There are no contraindications listed in the US manufacturer's labeling.

Canadian labeling: Hypersensitivity to dexmedetomidine or any component of the formulation.

Dosing: Adult

Note: Errors have occurred due to misinterpretation of dosing information. Maintenance dose expressed as mcg/kg/hour. Individualized and titrated to desired clinical effect. At recommended doses, dexmedetomidine does not provide adequate and reliable amnesia (when necessary); therefore, use of additional agents with amnestic properties (eg, benzodiazepines) may be necessary (Ebert 2000).

ICU sedation: IV: Initial: Loading infusion (optional; see "Note" below) of 1 mcg/kg over 10 minutes, followed by a maintenance infusion (see "Note" below) of 0.2 to 0.7 mcg/kg/hour; adjust rate to desired level of sedation; titration no more frequently than every 30 minutes may reduce the incidence of hypotension (Gerlach 2009)

Note: Loading infusion: The loading dose may be omitted for this indication if patient is either being converted from another sedative and patient is adequately sedated or there are concerns for hemodynamic compromise. Maintenance infusion: Dosing ranges between 0.2 to 1.5 mcg/kg/hour have been reported during randomized controlled clinical trials (Pandharipande 2007; Riker 2009). Although infusion rates as high as 2.5 mcg/kg/hour have been used, it is thought that doses >1.5 mcg/kg/hour do not add to clinical efficacy (Venn 2003). Manufacturer recommends duration of infusion should not exceed 24 hours; however, randomized clinical trials have demonstrated efficacy and safety comparable to lorazepam and midazolam with longer-term infusions of up to ~5 days (Pandharipande 2007; Riker 2009).

Procedural sedation: IV: Initial: Loading infusion of 1 mcg/kg (or 0.5 mcg/kg for less invasive procedures [eg, ophthalmic]) over 10 minutes, followed by a maintenance infusion of 0.6 mcg/kg/hour, titrate to desired effect; usual range: 0.2 to 1 mcg/kg/hour

Fiberoptic intubation (awake): IV: Initial: Loading infusion of 1 mcg/kg over 10 minutes, followed by a maintenance infusion of 0.7 mcg/kg/hour until endotracheal tube is secured (Bergese 2010).

Craniotomy (awake) (off-label use): IV: Initial: Loading infusion of 0.5 to 1 mcg/kg over 10 to 20 minutes, followed by a maintenance infusion of 0.5 mcg/kg/hour, titrate to desired effect (Bekker 2001; Bekker, 2008; Piccioni 2008; Shen 2013); usual range: 0.1 to 0.7 mcg/kg/hour (Piccioni 2008)

Dosing: Geriatric

ICU sedation: IV: Refer to adult dosing. Consider dosage reduction. No specific guidelines available. Dose selections should be cautious, at the low end of dosage range; titration should be slower, allowing adequate time to evaluate response.

Procedural sedation: IV: Refer to adult dosing: Initial: Loading infusion of 0.5 mcg/kg over 10 minutes; Maintenance infusion: Dosage reduction should be considered.

Dosing: Pediatric

Note: Errors have occurred due to misinterpretation of dosing information. Maintenance dose expressed as mcg/kg/hour. Individualize and titrate to desired clinical effect. At recommended doses, dexmedetomidine does not provide adequate and reliable amnesia (when necessary); therefore, use of additional agents with amnestic properties (eg, benzodiazepines) may be necessary (Ebert 2000).

ICU sedation: Infants, Children, and Adolescents: Limited data available:

Loading dose (Optional): IV: 0.5 to 1 mcg/kg/dose over 10 minutes (Chrysostomou 2009; Walker 2006); use of loading dose is dependent upon concomitant sedation agents and patient’s current and desired level of sedation

Maintenance dose: Continuous IV infusion: Initial: 0.2 to 0.5 mcg/kg/hour; adjust dose to desired level of sedation. Dosing based on multiple retrospective studies, case reports, and a few prospective studies. Most reported increasing by 0.1 to 0.3 mcg/kg/hour as needed. Reported maintenance dose variable, usual reported range was 0.4 to 0.7 mcg/kg/hour (Bejian 2009; Carroll 2008; Chrysostomou 2006; Chrysostomou 2009; Czaja 2009; Hosokawa 2010; Tobias 2004; Walker 2006; Whalen 2014). In general, infants may require higher maintenance infusion rates than either neonates or older children (Chrysostomou 2006; Chrysostomou 2009; Tobias 2004). Maximum reported doses varied; most utilized doses <1 mcg/kg/hour; however, doses as high as 2.5 mcg/kg/hour in intubated patients have been described (Carroll 2008). Although the manufacturer recommends duration of infusion should not exceed 24 hours, most studies reported use beyond this time period; most patients received infusion for ≤72 hours; however, one patient received dexmedetomidine for 103 days (Whalen 2014). Prolonged infusions should not be abruptly discontinued and are generally tapered over several days to prevent withdrawal symptoms.

Sedation/anesthesia, noninvasive procedures: Limited data available:

Loading dose: Infants, Children, and Adolescents: IV: 0.5 to 2 mcg/kg/dose over 10 minutes; may be repeated if sedation is not adequate (Ahmed 2014; Berkenbosch 2005; Koroglu 2006; Mason 2013; Siddappa 2011)

Maintenance dose: Infants, Children, and Adolescents: Continuous IV infusion: 0.5 to 1 mcg/kg/hour (Ahmed 2014; Berkenbosch 2005; Koroglu 2006; Mason 2013; Siddappa 2011). Dosing based on multiple retrospective and prospective studies in over 800 pediatric patients receiving dexmedetomidine (± other sedatives) for noninvasive procedures (eg, EEG, MRI, PET scan). In the largest, a retrospective study, 669 patients (age: 0.1 to 22.5 years) undergoing nuclear medicine imaging received dexmedetomidine for sedation. A bolus of 2 mcg/kg was administered over 10 minutes; this dose could be repeated up to 2 additional times if the predefined sedation score was not achieved; in addition, patients also received a maintenance infusion of 1 mcg/kg/hour. The mean time to achieve adequate sedation for all patients was 8.6 ± 4.6 minutes (range: 1 to 40 minutes). Hypotension, hypertension, and bradycardia occurred in 58.7%, 2.1% and 4.3% of patients, respectively; no patient required pharmacologic treatment. Hypotension and bradycardia were noted to be age related; risk of hypotension increased by 25% with each 5 year age increment increase and bradycardia occurred more often in children 3 to 12 years than any other age group. The authors concluded that the drug was well tolerated (Mason 2013).

Sedation, pre-anesthetic: Limited data available: Children and Adolescents (very limited data available in patients >9 years): Intranasal: 1 to 2 mcg/kg as a single dose 30 to 60 minutes prior to induction of anesthesia. Higher-end doses (2 mcg/kg) are recommended for older children (≥ 5 years) and adolescents (Talon 2009; Yuen 2012). Dosing based on multiple prospective studies (Akin 2012; Cimen 2013; Talon 2009; Wang 2014; Yuen 2012).

Reconstitution

Concentrated solution (100 mcg/mL): Must dilute in NS to achieve the required concentration (4 mcg/mL) prior to administration. Add 2 mL (200 mcg) of dexmedetomidine to 48 mL of NS for a total volume of 50 mL (4 mcg/mL) or 4 mL (400 mcg) of dexmedetomidine to 96 mL of NS for a total volume of 100 mL. Shake gently to mix.

Administration

Administer using a controlled infusion device. Advisable to use administration components made with synthetic or coated natural rubber gaskets. If loading dose used, administer over 10 minutes; may extend to 20 minutes to further reduce vasoconstrictive effects. Titration no more frequently than every 30 minutes may reduce the incidence of hypotension when used for ICU sedation (Gerlach 2009).

Storage

Bottles: Store at room temperature.

Vials: Store unopened vials (single-dose and multi-dose) at room temperature. Diluted solutions using multi-dose vials may be stored for up to 4 hours at room temperature or up to 24 hours at 2°C to 8°C (35°F to 46°F) prior to use.

Warnings/Precautions

Concerns related to adverse effects:

• Cardiovascular effects: Episodes of bradycardia, hypotension, and sinus arrest have been associated with rapid IV administration (eg, bolus administration) or when given to patients with high vagal tone. When used for ICU sedation, use of a loading dose is optional; for the maintenance infusion, titration no more frequently than every 30 minutes may reduce the incidence of hypotension (Gerlach 2009). If medical intervention is required, treatment may include stopping or decreasing the infusion, increasing the rate of IV fluid administration, use of pressor agents, and elevation of the lower extremities. At low concentrations, mean arterial pressure (MAP) may be reduced without changes in other hemodynamic parameters (eg, pulmonary artery occlusion pressure [PAOP]); however, at higher concentrations (>1.9 ng/mL), MAP, CVP, PAOP, PVR, and SVR increase (Ebert 2000).

• Transient hypertension: Has been primarily observed during loading dose administration and is associated with the initial peripheral vasoconstrictive effects of dexmedetomidine. Treatment is generally unnecessary; however, reduction of infusion rate may be required.

Disease-related concerns:

• Cardiovascular disease: Use with caution in patients with heart block, bradycardia, severe ventricular dysfunction, hypovolemia, or chronic hypertension. In a scientific statement from the American Heart Association, dexmedetomidine has been determined to be an agent that may exacerbate underlying myocardial dysfunction (magnitude: moderate) (AHA [Page 2016]).

• Diabetes: Use with caution in patients with diabetes mellitus; cardiovascular adverse events (eg, bradycardia, hypotension) may be more pronounced.

• Hepatic impairment: Use with caution in patients with hepatic impairment; dosage reductions recommended.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Elderly: Use with caution in the elderly; cardiovascular events (eg, bradycardia, hypotension) may be more pronounced. Dose reduction may be necessary.

Other warnings/precautions:

• Arousability: Patients may be arousable and alert when stimulated. This alone should not be considered as lack of efficacy in the absence of other clinical signs/symptoms.

• Experienced personnel: Should be administered only by persons skilled in management of patients in intensive care setting or operating room. Patients should be continuously monitored.

• Tolerance and tachyphylaxis: Use of infusions >24 hours has been associated with tolerance and tachyphylaxis and dose-related increase in adverse reactions.

• Withdrawal: When withdrawn abruptly in patients who have received >24 hours of therapy, withdrawal symptoms may result (eg, hypertension, tachycardia, nervousness, nausea, vomiting, agitation, headaches). Use for >24 hours is not recommended by the manufacturer.

Monitoring Parameters

Level of sedation; heart rate, respiration, rhythm, blood pressure; pain control. Note: Dexmedetomidine causes minimal respiratory depression, inhibits salivation, and is analgesic-sparing.

Critically-ill mechanically ventilated ICU patients: Assess and adjust sedation according to scoring system (Richmond Agitation-Sedation Scale [RASS] or Sedation-Agitation Scale [SAS]) (SCCM [Devlin 2018]).
