Regulatory and Compliance Guidance
When Diazepam appears on a claimant's medication list, claims professionals should assess whether the prescribing is appropriate for the compensable injury, whether the duration is within guidelines, and whether there are interactions with other medications on the claim.
Work capacity impact: As a CNS depressant, Diazepam may impair driving, operating machinery, and cognitive function. Work capacity certificates should reflect any medication-related restrictions.
Australia TGA / PBS / State Schemes
Classified as S4 under the Therapeutic Goods Administration (TGA).
Listed on the Pharmaceutical Benefits Scheme (PBS) for subsidised prescribing.
Flagged as reportable under SIRA guidelines in NSW. Claims involving this medication may require additional reporting and clinical justification.
All Australian workers compensation schemes flag benzodiazepine use as high-risk, particularly when combined with opioids. Duration should be limited and tapering plans documented.
United Kingdom NICE / MHRA / FPM
UK drug driving laws (Section 5A Road Traffic Act 2006) set specific limits for prescription drugs that cause impairment. Employers and occupational health advisors should assess fitness to work.
United States FDA / CDC / State WC
FDA approved for use in the United States.
FDA Boxed Warning: WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS; ABUSE, MISUSE, AND ADDICTION; and DEPENDENCE AND WITHDRAWAL REACTIONS • Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation (see WARNINGS and PRECAUTIONS ). • The use of benzodiazepines, including diazepam tablets, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes. Before prescribing diazepam tablets and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction (see WARNINGS ) . • The continued use of benzodiazepines, including diazepam tablets, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Abrupt discontinuation or rapid dosage reduction of diazepam tablets after continued use may precipitate acute withdrawal reactions, which can be life-threatening. To reduce the risk of withdrawal reactions, use a gradual taper to discontinue diazepam tablets or reduce the dosage (see DOSAGE AND ADMINISTRATION and WARNINGS ) .
The CDC and FDA have issued joint warnings about the risks of concurrent benzodiazepine and opioid use. Workers compensation adjusters should flag this combination for clinical review.
