This is an update of the review published on 'Drug therapy for anxiety in adult palliative care patients' in Issue 1, 2004 of The Cochrane Library. Anxiety is common in palliative care patients. It can be a natural response to impending death, but it may represent a clinically significant issue in its own right. It may also result from pain, or other untreated or poorly managed symptoms. When anxiety is severe or distressing drug therapy may be considered in addition to supportive care.
