Boxed warning: Only personnel trained in the administration of procedural sedation, and not involved in the conduct of the diagnostic or therapeutic procedure, should administer BYFAVO. 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. Hypersensitivity Reactions: Hypersensitivity reactions including anaphylaxis may occur. Neonatal Sedation and Withdrawal Syndrome: Receiving benzodiazepines during pregnancy can result in neonatal sedation and/or neonatal withdrawal. Pediatric Neurotoxicity: In developing animals, exposures greater than 3 hours cause neurotoxicity. Weigh benefits against potential risks when considering elective procedures in children under 3 years old.
