Warning: Personnel and Equipment for Monitoring and Resuscitation, and Risks from Concomitant Use with Opioid Analgesics and Other Sedative-Hypnotics

Only personnel trained in the administration of procedural sedation, and not involved in the conduct of the diagnostic or therapeutic procedure, should administer remimazolam.

Administering personnel must be trained in the detection and management of airway obstruction, hypoventilation, and apnea, including the maintenance of a patent airway, supportive ventilation, and cardiovascular resuscitation.

Remimazolam has been associated with hypoxia, bradycardia, and hypotension. Continuously monitor vital signs during sedation and through the recovery period.

Resuscitative drugs, and age-and size-appropriate equipment for bag/valve/mask assisted ventilation must be immediately available during administration of remimazolam.

Concomitant use of benzodiazepines with opioid analgesics may result in profound sedation, respiratory depression, coma, and death. The sedative effect of intravenous remimazolam can be accentuated by concomitantly administered CNS depressant medications, including other benzodiazepines and propofol. Continuously monitor patients for respiratory depression and depth of sedation .
