Abstract
Objective: This study aims to ascertain the experience and views of psychiatrists in relation to St John's Wort and alternative treatments generally.
Method: A questionnaire was posted to all members of the Royal Australian and New Zealand College of Psychiatrists living in Australia or New Zealand.
Results: Of the 1910 mailed questionnaires, 862 (45%) were returned. Eighty per cent of respondents had patients who had used the herb. Side-effects and drug interactions were reported by 28% and 8% respectively of these psychiatrists. Some adverse events were described as serious. Psychiatrist attitudes about St John's Wort and alternative treatments were positive overall and psychiatrists seemed willing to recommend St John's Wort despite limited evidence of its usefulness.
Conclusions: Psychiatrists in Australia and New Zealand regularly manage patients who take St John's Wort and a considerable number actually recommend the treatment. However, they also report side-effects and drug interactions. Psychiatrists should routinely enquire about their patients' use of alternative treatments, be mindful of possible side-effects and in particular be aware of the dangers of combining St John's Wort with other psychotropics.
