Bottom Line Patients with alcoholic liver disease (ALD) require collaborative care from specialists in addiction, gastroenterology, and psychiatry. Psychiatrists have a role in identifying signs of ALD, prescribing medication to treat alcohol use disorder, and encouraging abstinence. There is some evidence supporting specific medications for varying severity of disease and different phases of recovery. Pharmacotherapy Current Psychiatry 32 December 2015 decisions should be made case by case.
