WorkSafe Victoria medication prescribing standards

Expert overview of medication prescribing standards and governance for professional insurers in Victorian workers compensation

Published 3 April 2026

Introduction

Victoria's workers compensation scheme is administered by WorkSafe Victoria under the Workplace Injury Rehabilitation and Compensation Act 2013 (WIRC Act). Medication prescribing within this framework must align with WorkSafe principles emphasizing rehabilitation, functional recovery, and evidence-based treatment. For professional indemnity insurers and claims managers operating in Victoria, understanding WorkSafe medication prescribing standards is essential to optimal claims management and compliance with regulatory expectations.

This article provides a specialist overview of medication prescribing standards applicable to Victorian workers compensation claims.

WorkSafe Regulatory Framework and Principles

The WIRC Act 2013 establishes the legislative foundation for Victorian workers compensation. Treatment, including medications, must be:

• Reasonable and necessary for the treatment of the accepted injury.
• Evidence-based and aligned with established clinical guidelines.
• Delivered by appropriately qualified and registered healthcare practitioners.
• Consistent with rehabilitation objectives and functional recovery.

WorkSafe publishes guidelines and information materials providing guidance on treatment authorization and appropriateness. While WorkSafe does not issue detailed medication-specific protocols equivalent to some other regulatory frameworks, the reasonable and necessary test is the primary framework for assessing medication coverage and appropriateness.

Evidence-Based Prescribing Standards

Victorian prescribers are expected to follow the Therapeutic Guidelines and Australian Medicines Handbook as primary references for evidence-based prescribing. Additionally, WorkSafe recognizes the importance of professional regulatory standards from colleges including the Royal Australian College of General Practitioners (RACGP), the Australasian Society of Clinical and Experimental Pharmacologists and Toxicologists (ASEPT), and other relevant professional bodies.

For workers compensation claims, several medication categories warrant specific attention regarding prescribing standards.

Pain Management and Analgesic Prescribing

Pain management is central to most workers compensation claims. WorkSafe supports multimodal pain management combining physical therapy, psychological interventions, and appropriately selected pharmacological therapy. Evidence-based pain management in workers compensation emphasizes:

• Initial use of non-opioid analgesics (paracetamol, NSAIDs) where clinically appropriate.
• Careful consideration of opioid prescribing, with clear clinical justification and explicit timeframes for review.
• Integration of analgesic therapy with physical rehabilitation and functional restoration.
• Regular review of pain management efficacy with assessment of continued necessity and appropriateness.

WorkSafe expectations align with contemporary evidence emphasizing that opioid-focused pain management without concurrent rehabilitation may impede functional recovery. Prolonged opioid prescribing warrants particular scrutiny and may indicate need for review of overall pain management strategy.

Muscle Relaxants and Benzodiazepines

Muscle relaxants such as diazepam and other benzodiazepines are sometimes prescribed for acute muscle spasm following workplace injury. Best practice standards recommend limiting benzodiazepine prescribing to short-term use (typically 2-4 weeks) due to dependence risk and potential impedance of rehabilitation progress. Physiotherapy and exercise-based interventions should be prioritized over prolonged pharmacological spasticity management.

Psychotropic Medications

Workplace injuries frequently result in mood disturbance, anxiety, or post-traumatic stress. Selective serotonin reuptake inhibitors (SSRIs) are considered first-line pharmacological treatment. Importantly, WorkSafe typically provides funded access to psychological services, and these should be provided alongside or coordinated with psychotropic medication therapy.

Benzodiazepine Prescribing Governance

Benzodiazepine prescribing presents particular challenges in workers compensation claims. These medications carry dependence risk and may impair rehabilitation and return to work. Best practice governance aligns with WorkSafe's rehabilitation focus and includes:

• Time-limited prescribing (2-4 weeks maximum) with explicit deprescribing plan documented from outset.
• Regular clinical review by the prescriber, with particular scrutiny for prescribing extending beyond initial periods.
• Prioritization of alternative interventions including psychological support and sleep hygiene optimization.
• Documentation of dependence risk assessment, particularly for workers with personal or family history of substance use.

Opioid Prescribing in Workers Compensation

Opioid prescribing in workers compensation claims warrants careful governance due to dependence risk, functional impairment, and documented association with delayed return to work. Best practice includes:

• Clear clinical justification for initial opioid prescribing, including documentation that non-opioid therapies are inadequate.
• Regular assessment of opioid efficacy and appropriateness for continued use.
• Risk screening for dependence using validated tools.
• Explicit deprescribing planning with target timeframes for cessation.
• Integration of opioid therapy with rehabilitation and physical therapy to support functional recovery.

WorkSafe expectations increasingly align with contemporary evidence emphasizing cautious opioid use in occupational injury claims. Prolonged opioid therapy extending significantly beyond typical recovery timeframes may warrant insurer review and consideration of independent medication assessment.

Scheduling and Controlled Substance Prescribing

Victoria uses the Australian Standard for the Uniform Scheduling of Medicines and Poisons (SUSMP) to classify medications. Schedule 8 controlled drugs (including opioids and benzodiazepines) are subject to regulatory requirements including specific prescription forms and record-keeping obligations.

For Schedule 8 prescribing in workers compensation claims:

• Clear clinical documentation of indication and justification is required.
• Regular review by the prescriber should assess continued necessity and efficacy.
• Risk screening for dependence should be documented, particularly for claimants with relevant risk factors.
• Deprescribing planning should be documented, with explicit target dates for cessation.

Return to Work and Medication Appropriateness

A key objective of WorkSafe claims is supporting workers to return to work. Medication selection should be considered in relation to functional capacity and work feasibility. Medications impairing alertness, cognition, or motor function may impact return-to-work capability, particularly in safety-critical or cognitively demanding roles.

WorkSafe expects treating practitioners to document:

• Functional impact of medications relevant to the worker's job role and capacity.
• Consideration of medication adjustments where functional impairment affects work capacity.
• Coordination between medication management and return-to-work planning.
• Regular review of medication necessity as the worker's functional capacity improves.

Pharmacy Services and Medication Review

Community pharmacists in Victoria provide important medication review and support services. Pharmacy services relevant to workers compensation claims include:

Insurers managing workers compensation claims may benefit from engaging pharmacy services where:

• Complex polypharmacy requires assessment and rationalization.
• Long-term medication use warrants independent review and optimization.
• Benzodiazepine or opioid dependence risk requires deprescribing support.
• Medication-related functional impairment affects rehabilitation or return to work.

Independent Medication Review in Workers Compensation

Independent medication reviews by specialist pharmacists provide valuable assessment of medication appropriateness, dependence risk, and functional implications in complex claims. Medication review is particularly valuable in workers compensation scenarios including:

• Complex polypharmacy requiring assessment and optimization.
• Prolonged opioid or benzodiazepine prescribing.
• Medication-related functional impairment affecting return to work.
• Disputes regarding medication appropriateness or necessity.
• Need for deprescribing support and rehabilitation coordination.

Best Practice for WorkSafe Insurers

For insurers managing Victorian workers compensation claims, best practice medication governance should include:

• Early assessment: Review medication profile in early claims to identify potential governance concerns.
• Rehabilitation coordination: Ensure medication management is aligned with rehabilitation and return-to-work planning.
• Specialist engagement: Engage pain specialists, psychiatrists, or other medical specialists for complex medication scenarios.
• Regular review: Establish review protocols for long-term medication use, particularly Schedule 8 controlled drugs.
• Deprescribing support: Actively support deprescribing of time-limited medications as worker's condition improves.

Regulatory Developments and Future Trends

Victoria's workers compensation regulatory landscape continues to evolve, with increasing emphasis on opioid stewardship, evidence-based treatment, and early intervention. WorkSafe continues to refine guidance on treatment appropriateness and rehabilitation focus. The growing availability of independent medication review services with workers compensation expertise provides insurers with enhanced capacity to manage medication-related risk and support better worker outcomes.
