There is a paucity of data describing dexmedetomidine withdrawal syndrome (DWS) as well as clonidine's place in therapy for DWS. This review will describe and analyze current literature to provide clinical recommendations. SUMMARY A MEDLINE literature search was performed to identify original research articles describing DWS and/or transitioning from dexmedetomidine to clonidine for the purpose of weaning patients from sedation with dexmedetomidine. Four case reports describing DWS, 3 case reports describing the use of clonidine to treat DWS, and 3 observational studies describing the use of clonidine to facilitate dexmedetomidine weaning were identified. The incidence of and risk factors for DWS are unknown; factors including patient age and dexmedetomidine infusion rate, loading dose, and discontinuation strategy have inconsistent associations witermissions@oup.com.PURPOSE Evaluation of mechanisms used to cope with an i.v. fl
