Integrated Management of Co-Occurring Alcohol Use Disorder and Depression: Clinical Approaches for Concurrent Disorders.

Abstract

Co-occurring alcohol use disorder (AUD) and major depressive disorder (MDD) are common and complex conditions that significantly impact patient outcomes. The bidirectional relationship between alcohol use and depression complicates diagnosis and treatment, as alcohol exacerbates depressive symptoms and vice versa. Integrated treatment addressing both disorders simultaneously has shown better outcomes compared to sequential treatments. This article provides evidence-based clinical guidance for managing patients with co-occurring AUD and MDD, focusing on pharmacotherapy, psychotherapy and integrated care models. Pharmacologically, selective serotonin reuptake inhibitors and tricyclic antidepressants are commonly used to treat depression in individuals with AUD, while naltrexone and acamprosate are first-line medications for AUD. Combining antidepressants with AUD medications improves treatment efficacy. Psychotherapeutic interventions such as Cognitive-Behavioural Therapy (CBT) and Motivational Interviewing are essential components of treatment, focusing on addressing both alcohol use and depressive symptoms. Behavioural activation has also proven effective in treating depression while reducing alcohol cravings. Integrated care models, where both disorders are addressed simultaneously, yield the best outcomes and involve coordinated pharmacotherapy, psychotherapy and ongoing follow-up care. A case example of a 33-year-old woman with AUD and MDD highlights the success of an integrated treatment approach, where a combination of sertraline, naltrexone and CBT led to significant improvements in both mood and alcohol use. Clinicians are advised to differentiate between alcohol-induced depression and primary MDD, consider potential medication interactions, and incorporate ongoing psychotherapy and monitoring for optimal patient outcomes. This approach emphasizes the importance of addressing both conditions concurrently to achieve better long-term recovery outcomes for patients with co-occurring AUD and MDD.
