Suicide risk and antidepressants

The British Medical Journal has made a paper available through the Online First section of the website that examines the risk of suicide associated with several common antidepressants.

The study was a retrospective cohort study of the UK General Practice Research Database and examined suicide rates and attempted suicides associated with venlafaxine, citalopram, fluoxetine and dothiepin.

The observe suicide rates were as follows:

The risk of suicide is higher than baseline in patients treated common antidepressants. It remains unclear if this is a factor of depressive disease alone or if there is contribution from antidepressant therapy.

Action: Clinicians should assess suicide risk in all patients who exhibit symptoms of depression before commencing treatment.
