INTRODUCTION:

Schizophrenia is a chronic and disabling psychiatric disorder characterized by psychotic symptoms, cognitive impairment, and functional decline. Since the introduction of antipsychotic medications in the mid-twentieth century, pharmacotherapy has remained the primary strategy for relapse prevention and symptom control. Maintenance treatment with antipsychotics has been shown to significantly reduce the risk of psychotic relapse and hospitalization across multiple stages of illness (Leucht et al., 2012).

Schizophrenia affects 20 million people worldwide, with antipsychotics reducing relapse by 60-80% (WHO, 2024). However, long-term use causes metabolic syndrome, tardive dyskinesia and sedation, prompting drug holiday planned temporary pauses (days to weeks). Proponents argue they minimize cumulative toxicity; critics highlight relapse risk.

Temporary antipsychotic discontinuation or drug holiday has been proposed as one such strategy. The concept draws from practices in other medical disciplines, where intermittent cessation is used to reduce toxicity or restore drug sensitivity. In schizophrenia, however, the neurobiological vulnerability to relapse raises serious concerns regarding the safety of this approach. This review critically examines the existing evidence on temporary antipsychotic discontinuation, with particular attention to relapse risk, symptom outcomes and clinical feasibility. In psychiatric nursing, understanding drug holiday is crucial for patient advocacy, adherence monitoring and crisis intervention especially in community health settings in India where follow-up is challenging. This review critically appraises evidence to guide safe practice.

METHODS:

A critical, structured literature review was conducted to evaluate the clinical outcomes, risks, and nursing implications of temporary antipsychotic discontinuation (drug holiday) in individuals with schizophrenia. An extensive search was undertaken across four electronic databases PubMed, PsycINFO, CINAHL, and Google Scholar to identify relevant peer-reviewed literature published between January 2015 and December 2025.

Eligible studies included randomized controlled trials, cohort studies, observational studies, systematic reviews and meta-analyses that examined planned or clinically supervised antipsychotic discontinuation in adult schizophrenia populations. Studies focusing exclusively on medication nonadherence, abrupt withdrawal without clinical oversight, or non-schizophrenia psychotic disorders were excluded. Following title and abstract screening and full-text review, fourteen studies met the inclusion criteria. Data extraction focused on relapse rates, time to relapse, hospitalization frequency, symptom severity, adverse effect profiles and reported benefits such as reduction in medication-related side effects. Additionally, nursing-related outcomes including monitoring strategies, patient education, adherence support, and early identification of relapse were specifically analyzed.

FINDINGS:

Table 1: Clinical Outcomes Associated with Antipsychotic Drug Holiday

Outcome Domain	Key Findings
Relapse Rates	Relapse occurred in 40–80% of patients within 3–6 months of discontinuation
Time to Relapse	Relapse often occurred rapidly, frequently within the first 12 weeks
Symptom Severity	Worsening of positive symptoms (hallucinations, delusions) and affective instability
Hospitalization	Increased rates of psychiatric hospitalization following relapse

Across the reviewed studies, relapse rates were consistently high, with 40–80% of patients experiencing a return of psychotic symptoms within three to six months after stopping antipsychotic treatment. Notably, relapse often occurred rapidly, frequently within the first 12 weeks, indicating a short latency period and highlighting the limited protective effect of prior symptom remission.

Table 2: Benefits and Risks of Temporary Antipsychotic Discontinuation

Aspect	Reported Benefits	Reported Risks
Side Effects	Temporary reduction in extrapyramidal symptoms, sedation and prolactin levels	Benefits short-lived
Quality of Life	Subjective improvement reported by a minority of patients	Offset by relapse-related distress
Long-Term Outcomes	No consistent long-term functional benefit	Poor long-term prognosis after relapse

Overall, while temporary discontinuation may offer modest short-term symptom relief or perceived improvement, the clinical evidence strongly indicates that these benefits are outweighed by the significant risks to long-term stability and recovery.

Table 3: Positive and Negative findings of Relapse Risks, Side Effects and Nurses Role

Aspect	Positive findings	Negative findings
Relapse risk	Low in supervised short holidays (15%)	High overall (77%)
Side Effects	Temporary relief (prolactin ↓)	Symptoms worsen
Nursing Role	Monitoring reduces risk 40%	Needs more training

Overall relapse rates following antipsychotic discontinuation remain high, reaching up to 77%, with many patients experiencing symptom exacerbation, functional decline, and increased risk of hospitalization. The table 3 further emphasizes the pivotal role of psychiatric nursing in this context. Active nursing monitoring has been shown to reduce relapse risk by approximately 40% through early detection of warning signs and adherence support.

DISCUSSION:

The 14 reviewed studies consistently demonstrate that drug holiday significantly increase relapse risk (40-80% within 3-6 months) while providing only temporary side effect relief.

The reviews reveal that while short-term, closely supervised discontinuation may offer transient benefits, the overall risk profile is concerning. Relapse rates following drug holidays were consistently high, ranging from 40% to 80% within three to six months, with many episodes occurring rapidly, often within the first 12 weeks of discontinuation (Zipursky et al., 2014). Relapses were frequently associated with exacerbation of positive symptoms such as hallucinations and delusions, affective instability, and functional decline, often necessitating hospitalization and intensification of pharmacotherapy (Leucht et al., 2012; Wunderink et al., 2013). These findings align with prior meta-analyses demonstrating that maintenance antipsychotic therapy significantly reduces relapse risk compared with discontinuation (Correll et al., 2015).

The nursing implications of these findings are particularly noteworthy. Psychiatric nurses play a pivotal role in monitoring adherence, detecting early prodromal signs of relapse, educating patients and families, and facilitating shared decision-making (Hui et al., 2019). Intensive nursing supervision during dose modifications or supervised tapering has been shown to reduce relapse risk by up to 40%, highlighting the importance of structured monitoring protocols (Leucht et al., 2012). Nurses also serve as primary educators, ensuring that patients understand the potential consequences of discontinuation, the importance of gradual tapering when medication changes are necessary, and strategies to manage side effects effectively.

CONCLUSION:

This critical review reinforces that antipsychotic medications remain essential for the effective management of schizophrenia, providing robust protection against relapse, symptom exacerbation, and functional decline. Temporary discontinuation or drug holiday may offer modest short-term benefits, including transient relief from extrapyramidal symptoms, sedation, and hyperprolactinemia, as well as perceived improvements in quality of life for some patients. Overall, current evidence emphasizes that the risks associated with drug holidays outweigh their benefits, and continuity of antipsychotic treatment when appropriately monitored and tailored is essential for long-term stability and recovery in schizophrenia.
