increased risk of suicidal behaviour in adults aged less than 25 years
with psychiatric conditions who were treated with an antidepressant.
If you have thoughts of harming or killing yourself at any time, contact
your doctor or go to a hospital straight away.
You may find it helpful to tell a relative or close friend that you are
depressed or have an anxiety disorder, and ask them to read this leaflet.
