Children and adolescents
Amitriptyline Oral Solution should not be used in children under 6 years.
Amitriptyline Oral Solution is not recommended for the treatment of depression
in children under 16 years of age.

1. What Amitriptyline Oral Solution is and what it is used for
The name of your medicine is Amitriptyline Oral Solution. Amitriptyline belongs
to a group of medicines known as tricyclic antidepressants. Everybody has
substances called serotonin and noradrenaline in their brains. It is thought
that people with depression (and some other conditions) have less of these
substances compared to those without depression (or other conditions).
Amitriptyline works by increasing the amounts of these substances in the brain.
Amitriptyline also affects the muscles in the bladder and reduces the need to
pass urine.
Amitriptyline Oral Solution is used in the treatment of:
• depression (especially when associated with sleep disturbance)
• night-time bed-wetting in children aged six years and above.
2. What you need to know before you take Amitriptyline Oral Solution

(listed in section 6)
• are taking drugs called Monoamine Oxidase Inhibitors (MAOIs) for depression
• are recovering from a heart attack
• have blockage of the coronary arteries or heart failure
· are taking drugs that increase the QT interval of the ECG (heart trace)

thioridazine, sotalol

· have a blood disorder

A heart problem called “prolonged QT interval” (which is shown on your
electrocardiogram, ECG) and heart rhythm disorders (rapid or irregular heart
beat) have been reported with Amitriptyline Oral Solution. Tell your doctor
if you:
• have slow heart rate,
• have or had a problem where your heart cannot pump the blood round your
body as well as it should (a condition called heart failure),
• are taking any other medication that may cause heart problems, or
• have a problem that gives you a low level of potassium or magnesium, or
a high level of potassium in your blood.
When the medicine is given for bed-wetting:
1. you should not take amitriptyline with medicines known as anticholinergic
such as atropine, oxybutynin or orphenadrine.
2. your doctor may monitor your heart with an ECG (electrocardiogram) test
before giving this medicine
3. suicidal thoughts may occur when taking this medicine for bed-wetting.
See the information in the following section for advice.
Special care should be taken with elderly patients.
Thoughts of suicide and worsening of your depression or anxiety disorder
If you are depressed 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 have these kinds of thoughts if:
• you have previously had thoughts about killing or harming yourself

If you have thoughts about harming or killing yourself at any time,
contact your doctor or go to hospital straight away. You may find it
helpful to tell a close friend or relative that you are depressed, 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.
