Contributor: Aaron Lessen MD Educational Pearls: Opioid overdoses that are reversed with naloxone (Narcan), a mu-opioid antagonist, can precipitate acute withdrawal in some patients Treatment of opioid use disorder with buprenorphine can also precipitate withdrawal Opioid withdrawal symptoms include nausea, vomiting, diarrhea, and agitation Buprenorphine works as a partial agonist at mu-opioid receptors, which may alleviate withdrawal symptoms The preferred dose of buprenorphine is 16 mg Treatment of buprenorphine-induced opioid withdrawal is additional buprenorphine Adjunctive treatments may be used for other opioid withdrawal symptoms Nausea with ondansetron Diarrhea with loperamide Agitation with hydroxyzine References 1.
