A survey of combination antidepressant use in Australia

Objective: The aim of this study was to survey doctors working in psychiatry in Australia about the practice of using two antidepressants simultaneously.

Method: A postal survey was sent to all doctors in psychiatry in Australia enquiring about their prescribing history and their attitudes to combination antidepressants and related issues.

Results: Seventy-nine percent of respondents had used combination antidepressants. The most frequently reported combination was a selective serotonin reuptake inhibitor combined with a tricyclic antidepressant. Combinations of mirtazepine with venlafaxine and other antidepressants were the next most frequently used. Seventeen percent of respondents reported having seen a complication from combination antidepressants, 75% believed that Australian GPs should be given information on the use of combination antidepressants, 89% wished for more information on this topic, and 88% believed patients had a right to be informed of this option in their treatment. Use of combination antidepressants was more frequent than exceeding the recommended maximum dose of an individual antidepressant.

Conclusion: Combination antidepressants are used far more frequently in Australia than suspected previously. Research into safe and evidence-based practice is strongly indicated.

The white doctors' burden

This thesis analyses the history of the influence of the Australian medical profession on government policies and community attitudes towards Asia. It concludes that, apart from their support of progressivist policies between 1880 and 1930, Australia's doctors had only a small and largely self-interested influence on Australia's Asian engagement.
