For adult patients being converted from alternate sedative therapy: a loading dose may not be required. For patients over 65 years of age: Consider a dose reduction [see Use in Specific Populations (8.5) ] . For adult patients with impaired hepatic function: Consider a dose reduction [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] . Maintenance of Intensive Care Unit Sedation For adult patients: a maintenance infusion of 0.2 to 0.7 mcg/kg/ hour . The rate of the maintenance infusion should be adjusted to achieve the desired level of sedation. For patients over 65 years of age: Consider a dose reduction [see Use in Specific Populations (8.5) ]. For adult patients with impaired hepatic function: Consider a dose reduction [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] Initiation of Procedural Sedation For adult patients: a loading infusion of one mcg/kg over 10 minutes . For less invasive procedures such as ophthalmic surgery, a loading infusion of 0.5 mcg/kg given over 10 minutes may be suitable. For awake fiberoptic intubation in adult patients: a loading infusion of one mcg/kg over 10 minutes . For patients over 65 years of age: a loading infusion of 0.5 mcg/kg over 10 minutes [see Use in Specific Populations (8.5) ]. For adult patients with impaired hepatic function: Consider a dose reduction [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] . Maintenance of Procedural Sedation For adult patients: the maintenance infusion is generally initiated at 0.6 mcg/kg/ hour and titrated to achieve desired clinical effect with doses ranging from 0.2 to 1 mcg/kg/ hour . Adjust the rate of the maintenance infusion to achieve the targeted level of sedation. For awake fiberoptic intubation in adult patients: a maintenance infusion of 0.7 mcg/kg/ hour is recommended until the endotracheal tube is secured. For patients over 65 years of age: Consider a dose reduction [see Use in Specific Populations (8.5) ]. For adult patients with impaired hepatic function: Consider a dose reduction [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] . Table 2: Recommended Dosage in Pediatric Patients INDICATION DOSAGE AND ADMINISTRATION Initiation of Sedation During Non‑invasive Procedures For pediatric patients: • 1 month to less than 2 years: a loading infusion of 1.5 mcg/kg over 10 minutes. • 2 to less than 18 years: a loading infusion of 2 mcg/kg over 10 minutes. Consider a reduction in dosage if clinically indicated. Maintenance of Sedation During Non-invasive Procedures For pediatric patients: • 1 month to less than 18 years: the maintenance infusion is generally initiated at 1.5 mcg/kg/ hour and titrated to achieve desired clinical effect with dosage ranging from 0.5 to 1.5 mcg/kg/ hour. As clinically warranted, titrate the maintenance dose to individual patient clinical response. 2.3 Dosage Adjustment Due to possible pharmacodynamic interactions, a reduction in dosage of PRECEDEX or other concomitant anesthetics, sedatives, hypnotics or opioids may be required when co-administered [see Drug Interactions (7.1) ] . Dosage reductions may need to be considered for adult patients with hepatic impairment, and geriatric patients [see Warnings and Precautions (5.8) , Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] . 2.4 Preparation of Solution Strict aseptic technique must always be maintained during handling of PRECEDEX. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if product is discolored or if precipitate matter is present. PRECEDEX in 0.9% Sodium Chloride Injection, 80 mcg/20 mL (4 mcg/mL), 200 mcg/50 mL (4 mcg/mL), 400 mcg/100 mL (4 mcg/mL), and 1,000 mcg/250 mL (4 mcg/mL) PRECEDEX in 0.9% Sodium Chloride Injection is supplied in glass containers containing a premixed, ready to use dexmedetomidine hydrochloride solution in 0.9% sodium chloride in water. No further dilution of these preparations is necessary. 2.5 Administration with Other Fluids PRECEDEX infusion should not be co-administered through the same intravenous catheter with blood or plasma because physical compatibility has not been established. PRECEDEX has been shown to be incompatible when administered with the following drugs: amphotericin B, diazepam. PRECEDEX has been shown to be compatible when administered with the following intravenous fluids: • 0.9% sodium chloride in water • 5% dextrose in water • 20% mannitol • Lactated Ringer's solution • 100 mg/mL magnesium sulfate solution • 0.3% potassium chloride solution 2.6 Compatibility with Natural Rubber Compatibility studies have demonstrated the potential for absorption of PRECEDEX to some types of natural rubber. Although PRECEDEX is dosed to effect, it is advisable to use administration components made with synthetic or coated natural rubber gaskets.

Most common treatment-emergent adverse reactions, occurring in greater than 2% of adult patients in both Intensive Care Unit and procedural sedation studies include hypotension, bradycardia and dry mouth. Intensive Care Unit Sedation Adverse reaction information is derived from the continuous infusion trials of PRECEDEX for sedation in the Intensive Care Unit setting in which 1,007 adult patients received PRECEDEX. The mean total dose was 7.4 mcg/kg (range: 0.8 to 84.1), mean dose per hour was 0.5 mcg/kg/hr (range: 0.1 to 6.0) and the mean duration of infusion of 15.9 hours (range: 0.2 to 157.2). The population was between 17 to 88 years of age, 43% ≥65 years of age, 77% male and 93% Caucasian. Treatment-emergent adverse reactions occurring at an incidence of >2% are provided in Table 3 . The most frequent adverse reactions were hypotension, bradycardia and dry mouth [see Warnings and Precautions (5.2) ] .

The mean total dose was 1.6 mcg/kg (range: 0.5 to 6.7), mean dose per hour was 1.3 mcg/kg/hr (range: 0.3 to 6.1) and the mean duration of infusion of 1.5 hours (range: 0.1 to 6.2). The population was between 18 to 93 years of age, ASA I–IV, 30% ≥65 years of age, 52% male and 61% Caucasian. Treatment-emergent adverse reactions occurring in adults at an incidence of >2% are provided in Table 7 . The most frequent adverse reactions were hypotension, bradycardia, and dry mouth [see Warnings and Precautions (5.2) ] . Pre-specified criteria for the vital signs to be reported as adverse reactions are footnoted below the table. The decrease in respiratory rate and hypoxia was similar between PRECEDEX and comparator groups in both studies.

In pediatric patients 1 month to less than 2 years old, the median total dose for the PRECEDEX low, middle, and high dose treatment groups was 8.30, 18.90, and 22.75 mcg, respectively. The median duration of treatment ranged from 52.5 to 69 minutes across treatment groups. In pediatric patients 2 to less than 17 years old, the median total dose for the PRECEDEX low, middle, and high dose treatment groups was 21.30, 43.90, and 80.25 mcg, respectively. The median duration of treatment ranged from 56.5 to 66 minutes across treatment groups. All-causality treatment-emergent adverse reactions occurring in the combined age group of pediatric patients during the procedure at an incidence of >5% are provided in Table 8 . The most frequent treatment-emergent adverse events were bradypnea, bradycardia, hypertension, and hypotension [see Warnings and Precautions (5.2 , 5.3) ] . In the combined age group and in each age group, increased incidence in bradycardia and hypertension was observed with increasing PRECEDEX dose. Mild transient withdrawal symptoms of emergence delirium or agitation occurred in 3 of 122 patients after discontinuation of PRECEDEX infusion [see Warnings and Precautions (5.5) ] . All reported treatment‑emergent adverse reactions were mild to moderate in severity and the majority resolved without medical intervention. No subject in the study required airway intervention, including a jaw thrust or insertion of a nasal or oral airway. A similar profile was observed in the pediatric patients 1 month to less than 2 years old and in pediatric patients 2 to less than 17 years old. Pre‑specified criteria for the vital signs to be reported as adverse events are footnoted below the table.

Anesthetics, Sedatives, Hypnotics, Opioids: Enhancement of pharmacodynamic effects. Reduction in dosage of PRECEDEX or the concomitant medication may be required. ( 7.1 ) 7.1 Anesthetics, Sedatives, Hypnotics, Opioids Co-administration of PRECEDEX with anesthetics, sedatives, hypnotics, and opioids is likely to lead to an enhancement of effects. Specific studies have confirmed these effects with sevoflurane, isoflurane, propofol, alfentanil, and midazolam. No pharmacokinetic interactions between PRECEDEX and isoflurane, propofol, alfentanil and midazolam have been demonstrated. However, due to possible pharmacodynamic interactions, when co-administered with PRECEDEX, a reduction in dosage of PRECEDEX or the concomitant anesthetic, sedative, hypnotic or opioid may be required. 7.2 Neuromuscular Blockers In one study of 10 healthy adult volunteers, administration of PRECEDEX for 45 minutes at a plasma concentration of one ng/mL resulted in no clinically meaningful increases in the magnitude of neuromuscular blockade associated with rocuronium administration.
