This case report highlights the role of hospital-based modified assertive community treatment (ACT) in maintaining stability in a patient with dual diagnosis. We report a case of a middle-aged Indian gentleman who had schizophrenia with co-morbid alcohol abuse presented with multiple relapses, with recurrent suicidal attempts and criminal behaviour during his relapse episodes. After stabilisation of his most recent acute episode in hospital, the patient was followed-up by the community mental health team (CMHT). He was able to maintain in remission and stay free from alcohol, suicidality and criminal behaviour when provided ACT. The hospital-based modified ACT is proven to be effective in the management of this patient with co-morbidities and complications to sustain remission and prevent relapses.
