1. What Imipramine is and what it is used for

Imipramine belongs to a class of antidepressant drugs known as the
tricyclic antidepressant drugs. These medicines alter the levels of
chemicals in the brain to relieve the symptoms of depression.
Imipramine is used to treat depression. It can also be used to treat bedwetting in children.

medicine or any other tricyclics antidepressants

• if you are a young adult. Information from clinical trials has shown
an increased risk of suicidal behaviour in young adults (less than 25
years old) with psychiatric conditions who were treated with an
If you have thoughts of harming or killing yourself at any time,
contact your doctor or go to a hospital straight away.

is getting worse, or if they are worried about changes in your behaviour.
