Treatment starts with a single second-generation antipsychotic at the lowest effective dose — risperidone 1-2 mg initially, titrated slowly — because first-episode patients respond at roughly half the doses used in chronic illness and are exquisitely sensitive to side-effects. Baseline weight, fasting glucose, lipids and ECG are recorded before the first tablet. Treatment resistance is not declared until two adequate antipsychotic trials (4-6 weeks each at adequate dose) have failed, and remission should be consolidated with 12-24 months of maintenance before any cautious, supervised taper is contemplated. ## What you must remember - **DUP principle:** shorter duration of untreated psychosis predicts better outcomes; the "critical period" for deterioration is the first 2-5 years after onset. - **Start low, go slow:** first-episode patients need roughly half standard doses (risperidone 1-4 mg, olanzapine 5-10 mg); response assessment waits 4-6 weeks at an adequate dose. - **Baseline before the first dose:** weight and waist, fasting glucose and lipids, blood pressure, ECG, and in relevant cases pregnancy testing and substance screen — a favourite structured viva answer. - **Clozapine is not a first-line drug:** reserve for failure of two adequate trials; premature clozapine use in first-episode illness is an exam error. - **Duration of maintenance:** at least 1-2 years after full remission in a first episode; every taper attempt carries substantial relapse risk (commonly quoted around 50-80% within months of stopping) and must be gradual and supervised. - **Psychosocial package:** psychoeducation, family intervention targeting expressed emotion, CBT for psychosis, substance-use (especially cannabis) counselling, and early functional re-engagement — work or study, not waiting for "complete recovery". - **Indian context:** under the District Mental Health Programme, first episodes often present late with long DUP; cannabis potency in street preparations has risen, and cannabis-associated psychosis in young men is a growing presentation in Indian OPDs. ## The first two years, step by step Begin with a 22-year-old engineering student brought by family after a week of auditory hallucinations and referential ideas, cannabis positive on screen. Acute phase (weeks 0-6): engage without confrontation, admit only if risk or self-care demands it, start risperidone 1 mg at night increasing to 2-3 mg, treat the cannabis use as a parallel target, and complete the baseline metabolic panel. The family receives structured psychoeducation including the relapse-signature — the patient's own early warning pattern of sleeplessness and social withdrawal. Stabilisation (months 2-12): once symptoms settle, the priorities invert toward recovery — graded return to studies, CBT for residual delusional distress, family sessions to lower criticism and over-involvement, and honest discussion of the maintenance timeline. Consolidation (months 12-24): if fully remitted and functioning, some guidelines support a slow, monitored dose reduction with a pre-agreed relapse plan; in India, where follow-up is irregular and medication access may lapse, the clinician weighs the very real risk of silent discontinuation when planning any taper. Relapse is handled as information, not failure — search for the cause (adherence, substance use, stressor) and restart effective treatment early. ## Where students slip Three recurring slips: escalating dose rapidly in week one when the patient is merely sedated rather than responding; declaring "treatment-resistant schizophrenia" after one partial trial — the definition demands two adequate trials of 4-6 weeks each before the word resistance is used, and only then does clozapine enter; and counselling permanent treatment after a single episode, when guidelines actually support time-limited maintenance with a planned review. The exam also likes the differential buried in first-episode stems — autoimmune encephalitis in a patient with seizures and dyskinesias, or steroid-induced psychosis — before accepting schizophrenia. ## Frequently asked questions ### What is duration of untreated psychosis and why does it matter? DUP is the time from onset of frank psychotic symptoms to start of adequate treatment; longer DUP is consistently associated with poorer symptomatic and functional outcomes. ### At what doses are antipsychotics started in first-episode psychosis? Roughly half of standard chronic-illness doses — for example risperidone 1-2 mg initially — because first-episode patients are more responsive and more side-effect sensitive. ### When can treatment-resistant schizophrenia be diagnosed in a first episode? Only after two adequate antipsychotic trials (appropriate dose for 4-6 weeks each, with adherence confirmed) have failed, at which point clozapine becomes the indicated drug. ### How long should antipsychotics be continued after a first episode with full remission? At least 12-24 months, with any subsequent taper gradual and closely supervised because early discontinuation carries a high relapse risk. ### Which psychosocial interventions are core in first-episode care? Psychoeducation, family intervention to reduce expressed emotion, CBT for psychosis, substance-use counselling and early vocational reintegration.
