1. WHAT AMITRIPTYLINE IS FOR
Amitriptyline belongs to a group of medicines called tricyclic antidepressants. These medicines alter the levels of chemicals in your brain to relieve the symptoms of depression.
Amitriptyline can be used to treat:
• the symptoms of depression
• bed-wetting at night by children
If you are not sure why you have been prescribed these tablets then please ask your doctor.
2. BEFORE YOU TAKE AMITRIPTYLINE
Do not take Amitriptyline and tell your doctor if you:
• are allergic to Amitriptyline or any of the other ingredients in the tablets (listed in section 6 of this leaflet)
• have heart problems such as irregular heartbeats, heart block or have recently had a heart attack
• have severe liver problems
• are taking other medicines to treat depression known as Monoamine Oxidase Inhibitors (MAOIs) or you have taken MAOIs within the last 14 days
• suffer from mania (feeling over-excited, which causes unusual behaviour)
• are pregnant, planning a pregnancy or are breast-feeding
• have an inherited iron disorder (porphyria)
Amitriptyline should not be given to children under 7 years of age.
Take special care with Amitriptyline
Tell your doctor before you take this medicine if you:
• have epilepsy
• have a mental health problem such as schizophrenia or manic depression
• have problems with your liver or heart
• have increased pressure in your eye (glaucoma)
• cannot pass urine or have an enlarged prostate gland

• have a tumour called phaeochromocytoma, which is usually near the kidney and can cause high blood pressure
Tell your doctor or dentist that you are taking Amitriptyline if you are going to have an anaesthetic for an operation or dental treatment.
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 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. 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.
