Faculty of Pain Medicine, ANZCA
Recommendations from the Faculty of Pain Medicine, ANZCA on chronic pain, neuropathic pain and low back pain. The Faculty of Pain Medicine is a faculty of the Australian and New Zealand College of Anaesthetists and is the professional organisation for specialist pain medicine physicians (Fellows) and specialist pain medicine physicians in training (trainees). The Faculty is responsible for the training, examination and specialist accreditation of specialist pain medicine physicians and for the standards of clinical practice for pain medicine in Australia and New Zealand. Formed in 1998, the Faculty is the first multidisciplinary medical academy in the world to be devoted to education and training in pain medicine.
Do not prescribe benzodiazepines for low back pain.
Lifetime prevalence of low back pain in Australia is reported to be as high as 80% with one in ten experiencing significant activity limitation.
Although benzodiazepines continue to be commonly prescribed as ‘muscle relaxants’ for low back pain (LBP), there is an absolute lack of evidence of benefit for this indication. Only one RCT has been conducted on diazepam in acute LBP during the last 40 years, and it showed no additional benefit when added to NSAID therapy alone. A recent systematic review found no additional studies to support the use of benzodiazepines in treating acute or chronic back pain.
Well-described risks are associated with benzodiazepine usage, including abuse, addiction, tolerance and overdose. Accidental death from pharmaceutical benzodiazepines in Australia were highest in the 40–49 and 30–39 year age groups. The number of deaths in the older age groups also remains high.
There is no place for use of benzodiazepine for low back pain.

The Faculty of Pain Medicine (FPM), ANZCA established a working group to develop a preliminary list of pain medicine related practices that were identified, using current clinical evidence, as having possible limited benefit, no benefit or which may potentially cause harm to patients. An online survey tool was used to survey all FPM fellows and trainees inviting them to rank these recommendations and to provide any comment related to them. This engagement facilitated consensus and informed the Fellows and trainees about FPM’s involvement with the Choosing Wisely campaign.
FPM's final list of 5 Choosing Wisely recommendations reflects those that were the most broadly supported by the clinicians and which were considered to be the most relevant to community practice.
FPM Board directed that a poll of the fellowship be conducted to assess support for a sixth Choosing Wisely recommendation regarding the role of medicinal cannabis in chronic non-cancer pain treatment. The survey question was very similar to the final wording of the recommendation, and was supported by 79% of the fellows who responded (more than 25% of the active fellowship).
The final draft wording of the recommendation, explanation and list of key references was then approved by the Board and sent to Choosing Wisely for consideration by the Representative Panel. Feedback obtained from that consultation was then collated and discussed at the following Board meeting before some minor amendments were made to clarify the explanation section of the recommendation.
- 1 Avoid prescribing opioids (particularly long-acting opioids) as first-line or monotherapy for chronic non-cancer pain (CNCP).
- 2 Do not continue opioid prescription for chronic non-cancer pain (CNCP) without ongoing demonstration of functional benefit, periodic attempts at dose reduction and screening for long-term harms.
- 3 Avoid prescribing pregabalin and gabapentin for pain which does not fulfil the criteria for neuropathic pain
- 4 Do not prescribe benzodiazepines for low back pain.
- 5 Do not refer axial lower lumbar back pain for spinal fusion surgery.
- 6 Do not prescribe currently available medicinal cannabis products to treat chronic non-cancer pain (CNCP) unless part of a registered clinical trial.
