Prolonged dexmedetomidine infusion as an adjunct in treating sedation-induced withdrawal.

IMPLICATIONS: Dexmedetomidine, an alpha(2)-adrenoceptor agonist, is indicated for sedating patients on mechanical ventilation. It has been approved by the Food and Drug Administration for 24-h use. This is a report concerning a patient in whom a continuous infusion of dexmedetomidine was safely used for a week to help in averting frank withdrawal symptoms from an opioid and benzodiazepines.
