A 58-year-old man with a long history of alcohol use disorder is brought to the ED by his family for confusion, unsteady gait, and abnormal eye movements. On exam, he is disoriented to time, demonstrates a wide-based ataxic gait, and has bilateral lateral rectus palsy. Vitals are stable. Labs show mild macrocytic anemia and elevated AST > ALT. The NP suspects Wernicke’s encephalopathy. Which is the most appropriate immediate intervention?
