Thoughts of suicide and worsening of your depression or anxiety disorder

If you are depressed and/or have anxiety disorders you can sometimes have thoughts of harming or killing yourself. These may 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 yourself;

■    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 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. You might ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behaviour.

If any of the above apply to you, tell your doctor or pharmacist.

The following medicines may interact with your Allegron tablets:

■    guanethidine, debrisoquine, bethanidine, clonidine

(used to treat high blood pressure);

■    barbiturates (used for anxiety or to make you feel sleepy);

■    alcohol (you should not drink alcohol);

■    fluoxetine (another antidepressant);

■    phenothiazines (for mental illness);
