Thoughts of suicide and worsening of your depression or
anxiety disorder
If you are depressed and/or have anxiety disorders you can

be increased when first starting antidepressants, since these
medicines all take time to work, usually about two weeks but
sometimes longer.
You may be more likely to think like this:
 If you have previously had thoughts about killing or harming
 If you are a young adult. Information from clinical trials has
shown an 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
