1. What Amitriptyline is and what it is used for

Amitriptyline belongs to a group of drugs called tricyclic antidepressants (TCADs). These medicines alter the levels of chemicals in the brain to relieve the symptoms of depression.

Amitriptyline may be used:

•    to treat the symptoms of depression.

•    for the relief of bed-wetting at night by children.

2. What you need to know before you take Amitriptyline

Do not take Amitriptyline and tell your doctor if you

•    are allergic (hypersensitive) to amitriptyline, other tricyclic antidepressants or any of the other ingredients in these tablets (listed in section 6).

•    are taking monoamine oxidase inhibitors (MAOI), or you have stopped taking these medicines within the last14 days.

•    have heart disease including irregular heart beats, heart block, heart failure, coronary artery disease or have had a recent heart attack.

•    suffer from periods of increased and exaggerated behaviour (mania).

•    are pregnant or breast-feeding.

•    have severe liver disease.

•    are under 16 years old.

Warnings and precautions

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 young adults (less than 25 years old) 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.

Talk to your doctor or pharmacist before taking Amitryptiline if you or your child:

•    have any blood disorders (you may bruise easily, frequently suffer from infections or be anaemic).

•    have any psychiatric (mental) disorder (eg schizophrenia or manic depression).

•    are not able to pass water.

•    have been told you have an enlarged prostate gland.

•    suffer from porphyria (a deficiency of specific enzymes within the body, causing an increase of substances called porphyrins).

•    have a diseased thyroid gland

•    have a history of epilepsy.

•    suffer from narrow-angle glaucoma (increased pressure in the eye resulting in loss of vision).

•    are being given electroconvulsive therapy (ECT)

•    are planning to have surgery (including dental), as Amitriptyline may need to be stopped before you have a general anaesthetic.

If you are elderly, you are more likely to suffer from certain side effects (see section 4).

You may not see an improvement in your depression during the first month of treatment. Your doctor may want to monitor you during this time.
