A Clinical Psychologist is concerned with the Identification of the behavior of the patient and its analysis. He/she can provide psychological support to the patients by providing counselling sessions etc but they can’t prescribe medicine. As per the Medical Council of India, a trained practitioner with a MBBS degree and having specialization course in Psychiatry (Diploma/any other course) is only allowed to prescribe medicine provided he/she is a licensed practioner.
So only a Psychiatrist can prescribe medicine to patients and not the Psychologist.
