■1 What Amitriptyline tablets are and what they are used for

Check with your doctor or pharmacist before taking Amitriptyline tablets if you or your child (if they are the patient):

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

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

•    have liver or cardiovascular disease

•    are not able to pass water or have an enlarged prostate


•    have an overactive thyroid gland and are taking medicines to treat a thyroid disorder

•    have a history of epilepsy

•    are being given electroconvulsive therapy (ECT)

•    have increased pressure in the eye (glaucoma)

•    are due to have any surgery, including dental, that involves an anaesthetic.

Amitriptyline belongs to a group of medicines called tricyclic antidepressant drugs. These medicines alter the levels of chemicals in the brain to relieve the symptoms of depression. Amitriptyline is used:

•    to treat the symptoms of depression.

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

2 Before you take

Do not take Amitriptyline tablets and tell your doctor if you or your child (if they are the patient):

•    are allergic (hypersensitive) to amitriptyline, other tricyclic antidepressants or any of the other ingredients (see section 6). The 25mg tablets contain sunset yellow (E110), which may cause allergic-type reaction.

•    have heart disease such as irregular heart beats, heart block or failure, coronary artery disease or have recently had a heart attack

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

•    have severe liver disease

•    are taking monoamine oxidase inhibitors (MAOI) or you have taken MAOIs within the previous 14 days for depression

•    are breast-feeding

•    if the child is under 7 years old.

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.
