( 1.1 ) Sedation of non-intubated adult patients prior to and/or during surgical and other procedures. ( 1.2 ) Sedation of non-intubated pediatric patients aged 1 month to less than 18 years prior to and during non-invasive procedures. ( 1.2 ) 1.1 Intensive Care Unit Sedation Dexmedetomidine hydrochloride in 0.9% sodium chloride injection is indicated for sedation of initially intubated and mechanically ventilated adult patients during treatment in an intensive care setting. Dexmedetomidine hydrochloride in 0.9% sodium chloride injection should be administered by continuous infusion not to exceed 24 hours. Dexmedetomidine hydrochloride in 0.9% sodium chloride injection has been continuously infused in mechanically ventilated adult patients prior to extubation, during extubation, and post-extubation. It is not necessary to discontinue dexmedetomidine hydrochloride in 0.9% sodium chloride injection prior to extubation. 1.2 Procedural Sedation Dexmedetomidine hydrochloride in 0.9% sodium chloride injection is indicated for sedation of non-intubated adult patients prior to and/or during surgical and other procedures. …

Monitoring: Continuously monitor patients while receiving dexmedetomidine. ( 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 Dexmedetomidine 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 dexmedetomidine, patients should be continuously monitored while receiving dexmedetomidine. 5.2 Hypotension, Bradycardia, and Sinus Arrest …

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 …
