Warnings and precautions
Talk to your doctor or pharmacist before taking Amitriptyline Tablets.
Heart rhythm disorders and hypotension may occur if you receive a high dosage of amitriptyline. This might also occur in usual doses if you have pre-existing heart disease.
Prolonged QT interval
A heart problem called ?prolonged QT interval? (which is shown on your electrocardiogram, ECG) and heart rhythm disorders (rapid or irregular heartbeat) have been reported with Amitriptyline Tablets. Tell your doctor if you:
- have slow heart rate,
- have or had a problem where your heart cannot pump the blood around 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
- have a surgery planned as it might be necessary to stop the treatment with amitriptyline before you are given anaesthetics. In the case of acute surgery, the anaesthetist should be informed about the treatment of amitriptyline.
- have an overactive thyroid gland or receive thyroid medication.
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 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, 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.
Episodes of mania
Some patients with manic-depressive illness may enter into a manic phase. This is characterized by profuse and rapidly changing ideas, exaggerated gaiety and excessive physical activity. In such cases, it is important to contact your doctor who probably will change your medication.

- narrow-angle glaucoma (loss of vision due to abnormally high pressure in the eye)
- epilepsy, a history of convulsions or fits
- difficulty in passing urine
- enlarged prostate
- thyroid disease
- bipolar disorder
- severe liver disease
severe heart disease
stenosis (narrowing of the gastric outlet) and paralytic ileus (blocked

If you use antidepressants such as SSRIs, your doctor might consider changing the dose of your medicine (see also section 2 other medicines and Amitriptyline Tablets and section 3)
Elderly are more likely to suffer from certain side effects, such as dizziness when you stand up due to low blood pressure (see also section 4 Possible side effects).

- This medicines should not be taken at the same time as an anticholinergic drug (see also section 2 Other medicines and Amitriptyline Tablets)
- Suicidal thoughts and behaviours may also develop during early treatment with antidepressants for disorders other than depression; the same precautions observed when treating patients with depression should, therefore, be followed when treating patients with bedwetting
