5 WARNINGS AND PRECAUTIONS • Monitoring : Continuously monitor patients while receiving PRECEDEX. ( 5.1 ) • Bradycardia and Sinus Arrest : Have occurred in young healthy volunteers with high vagal tone or with different routes of administration, e.g., rapid intravenous or bolus administration. ( 5.2 ) • Hypotension and Bradycardia : May necessitate medical intervention. May be more pronounced in patients with hypovolemia, diabetes mellitus, or chronic hypertension, and in the elderly. Use with caution in patients with advanced heart block or severe ventricular dysfunction. ( 5.2 ) • Co-administration with Other Vasodilators or Negative Chronotropic Agents : Use with caution due to additive pharmacodynamic effects. ( 5.2 ) • Transient Hypertension : Observed primarily during the loading dose. Consider reduction in loading infusion rate. ( 5.3 ) • Arousability : Patients can become aroused/alert with stimulation; this alone should not be considered as lack of efficacy. ( 5.4 ) • Tolerance and Tachyphylaxis : Prolonged exposure to dexmedetomidine beyond 24 hours may be associated with tolerance and tachyphylaxis and a dose-related increase in adverse events. ( 5.7 ) 5.1 Drug Administration PRECEDEX should be administered only by persons skilled in the management of patients in the intensive care or operating room setting. Due to the known pharmacological effects of PRECEDEX, patients should be continuously monitored while receiving PRECEDEX. 5.2 Hypotension, Bradycardia, and Sinus Arrest Clinically significant episodes of bradycardia and sinus arrest have been reported with PRECEDEX administration in young, healthy adult volunteers with high vagal tone or with different routes of administration including rapid intravenous or bolus administration. Reports of hypotension and bradycardia have been associated with PRECEDEX infusion. Some of these cases have resulted in fatalities. If medical intervention is required, treatment may include decreasing or stopping the infusion of PRECEDEX, increasing the rate of intravenous fluid administration, elevation of the lower extremities, and use of pressor agents. Because PRECEDEX has the potential to augment bradycardia induced by vagal stimuli, clinicians should be prepared to intervene. The intravenous administration of anticholinergic agents (e.g., glycopyrrolate, atropine) should be considered to modify vagal tone. In clinical trials, glycopyrrolate or atropine were effective in the treatment of most episodes of PRECEDEX-induced bradycardia. However, in some patients with significant cardiovascular dysfunction, more advanced resuscitative measures were required. Caution should be exercised when administering PRECEDEX to patients with advanced heart block and/or severe ventricular dysfunction. Because PRECEDEX decreases sympathetic nervous system activity, hypotension and/or bradycardia may be expected to be more pronounced in patients with hypovolemia, diabetes mellitus, or chronic hypertension and in elderly patients. In clinical trials where other vasodilators or negative chronotropic agents were co-administered with PRECEDEX an additive pharmacodynamic effect was not observed. Nonetheless, caution should be used when such agents are administered concomitantly with PRECEDEX. 5.3 Transient Hypertension Transient hypertension has been observed primarily during the loading dose in association with the initial peripheral vasoconstrictive effects of PRECEDEX. Treatment of the transient hypertension has generally not been necessary, although reduction of the loading infusion rate may be desirable. 5.4 Arousability Some patients receiving PRECEDEX have been observed to be arousable and alert when stimulated. This alone should not be considered as evidence of lack of efficacy in the absence of other clinical signs and symptoms. 5.5 Withdrawal Intensive Care Unit Sedation With administration up to 7 days, regardless of dose, 12 (5%) PRECEDEX adult subjects experienced at least 1 event related to…

7 DRUG INTERACTIONS 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.

8.1 Pregnancy Risk Summary Available data from published randomized controlled trials and case reports over several decades of use with intravenously administered dexmedetomidine during pregnancy have not identified a drug-associated risk of major birth defects and miscarriage; however, the reported exposures occurred after the first trimester. Most of the available data are based on studies with exposures that occurred at the time of caesarean section delivery, and these studies have not identified an adverse effect on maternal outcomes or infant Apgar scores. Available data indicate that dexmedetomidine crosses the placenta. In animal reproduction studies, fetal toxicity that lower fetal viability and reduced live fetuses occurred with subcutaneous administration of dexmedetomidine to pregnant rats during organogenesis at doses 1.8 times the maximum recommended human dose (MRHD) of 17.8 mcg/kg/day. Developmental toxicity (low pup weights and adult offspring weights, decreased F1 grip strength, increased early implantation loss and decreased viability of second-generation offspring) occurred when pregnant rats were subcutaneously administered dexmedetomidine at doses less than the clinical dose from late pregnancy through lactation and weaning (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. Data Animal Data Increased post-implantation losses and reduced live fetuses in the presence of maternal toxicity (i.e. decreased body weight) were noted in a rat embryo-fetal development study in which pregnant dams were administered subcutaneous doses of dexmedetomidine 200 mcg/kg/day (equivalent to 1.8 times the intravenous MRHD of 17.8 mcg/kg/day based on body surface area [BSA]) during the period of organogenesis (Gestation Day [GD] 6 to 15). No malformations were reported. No malformations or embryo-fetal toxicity were noted in a rabbit embryo-fetal development study in which pregnant does were administered dexmedetomidine intravenously at doses of up to 96 mcg/kg/day (approximately half the human exposure at the MRHD based on AUC) during the period of organogenesis (GD 6 to 18). Reduced pup and adult offspring birth weights, and grip strength were reported in a rat developmental toxicology study in which pregnant females were administered dexmedetomidine subcutaneously at doses of 8 mcg/kg/day (0.07 times the MRHD based on BSA) during late pregnancy through lactation and weaning (GD 16 to postnatal day [PND] 25). Decreased viability of second generation offspring and an increase in early implantation loss along with delayed motor development occurred in the 32 mcg/kg/day group (equivalent to less than the clinical dose based on BSA) when first generation offspring were allowed to mate. This study limited dosing to hard palate closure (GD 15 to 18) through weaning instead of dosing from implantation (GD 6 to 7) to weaning (PND 21). In a study in the pregnant rat, placental transfer of dexmedetomidine was observed when radiolabeled dexmedetomidine was administered subcutaneously.

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) ] .
