MSFinals-5635

A 55-year-old man with a history of paranoid schizophrenia experiences a recurrence of symptoms due to irregular medication intake, leading to his admission under section 2 of the Mental Health Act following a formal mental state assessment. He had been taking Risperidone orally once daily for several years, which had effectively stabilized his mental state while living in the community. Considering his non-adherence, what treatment option would be most appropriate for this individual?
