A 32-year-old woman with a 5-year history of schizophrenia, currently on olanzapine 15 mg daily, presents with persistent auditory hallucinations, delusions of reference, and poor medication adherence. Her family reports she stopped taking medication 2 months ago. She denies suicidal or homicidal ideation. Mental status examination confirms active psychotic symptoms. What is the most appropriate next step in management?

Question

Accepted Answer

C. Admit to psychiatric ward for stabilization and assessment of treatment resistance; consider long-acting intramuscular antipsychotic after stabilization. ## Management of Relapse Due to Non-Adherence in Schizophrenia

**Key Point:** A patient with established schizophrenia who relapses due to medication non-adherence requires inpatient stabilization, assessment of treatment response, and consideration of long-acting injectable (LAI) antipsychotics to prevent future non-adherence.

### Why Admission Is Indicated

| Factor | This Patient | Clinical Significance |
| --- | --- | --- |
| **Active psychosis** | Yes (hallucinations, delusions) | Requires inpatient assessment and stabilization |
| **Non-adherence history** | Yes (stopped meds 2 months ago) | High risk of relapse; needs structured environment |
| **Insight** | Poor (no mention of recognizing illness) | Unlikely to comply with outpatient regimen |
| **Functional status** | Declining | Supports need for inpatient care |
| **Safety risk** | Denies SI/HI but psychotic | Inpatient observation warranted |

**High-Yield:** Non-adherence is the leading cause of relapse in schizophrenia. Inpatient admission allows:
- Direct observation of medication administration
- Assessment of treatment response and side effects
- Evaluation for treatment resistance
- Planning of adherence-enhancing interventions (LAI antipsychotics)

### Long-Acting Injectable (LAI) Antipsychotics

**Clinical Pearl:** After stabilization on oral antipsychotics, LAI agents should be offered to patients with:
- History of non-adherence
- Multiple relapses
- Poor insight
- Chronic schizophrenia

Common LAI options:
- Paliperidone palmitate (monthly or 3-monthly)
- Fluphenazine decanoate (fortnightly)
- Haloperidol decanoate (monthly)

### Why NOT Increase Olanzapine?

The problem is not inadequate dosing—it is non-adherence. Increasing the dose of a medication the patient is not taking will not improve outcomes. The focus must shift to adherence strategies.

**Warning:** Do NOT confuse "poor response" (medication not working) with "poor adherence" (patient not taking medication). This patient has relapsed due to stopping medication, not due to treatment resistance.
