The American College of Physicians recommends monitoring vital signs and Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scores every 4-6 hours during acute withdrawal phase, with a strength of evidence rated as high 1
The National Institute of Health suggests providing thiamine supplementation (100mg IV/IM daily) before glucose administration to prevent Wernicke's encephalopathy, with a moderate level of evidence 2

The American Psychiatric Association recommends choosing from aripiprazole, quetiapine, risperidone, or olanzapine for augmentation of antidepressant therapy, with a high strength of evidence 3
The American College of Physicians suggests quetiapine may offer dual benefits as it has some evidence for mood stabilization and can assist with insomnia common in early recovery, with a moderate level of evidence 3

The National Institute of Mental Health recommends monitoring treatment response within 1-2 weeks of initiating antidepressant/antipsychotic combination, assessing for therapeutic effects, adverse effects, and suicidality, with a high strength of evidence 4
The American Psychiatric Association suggests using standardized tools such as PHQ-9 or HAM-D to track depressive symptom severity, with a moderate level of evidence 4

The American College of Physicians recommends modifying treatment through dose adjustment, medication switch, or alternative augmentation strategies if inadequate response by 6-8 weeks, with a high strength of evidence 4
The National Institute of Health defines treatment response as ≥50% reduction in measured severity on validated depression scales, with a moderate level of evidence 4

The American Psychiatric Association recommends continuing antidepressant therapy for 4-9 months minimum after satisfactory response for first episodes, with longer duration (≥1 year) for recurrent episodes, with a high strength of evidence 4

The National Institute of Mental Health emphasizes the importance of monitoring closely for suicidality, especially during the initial treatment period when psychotic depression carries particularly high suicide risk, with a high strength of evidence 4
The American College of Physicians warns that inadequate monitoring of withdrawal symptoms can lead to preventable complications including seizures and delirium tremens from alcohol withdrawal, with a moderate level of evidence 1
