Neuropathic pain in adults
Chronic tension type headache prophylaxis in adults
Migraine prophylaxis in adults

This medicine should only be prescribed by doctors with expertise in treating patients with persistent bed-wetting.

2. What you need to know before you take Amitriptyline Oral Solution

Do not take Amitriptyline Oral Solution if you:

are allergic to amitriptyline or to any of the other ingredients of this medicine (listed in section 6)
if you recently have had a heart attack (myocardial infarction)
if you have heart problems such as disturbances in heart rhythm which are seen on an electrocardiogram (ECG), heart block, or coronary artery disease
if you are taking medicines known as monoamine oxidase inhibitors (MAOIs)
if you have taken MAOIs within the last 14 days
if you have taken moclobemide the day before
if you have a severe liver disease.

If you are treated with Amitriptyline Oral Solution, you have to stop taking this medicine and wait for 14 days before you start treatment with a MAOI.

This medicine should not be used for children below 6 years of age.

Warnings and precautions

Talk to your doctor before taking Amitriptyline Oral Solution:

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 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
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 over active thyroid gland or receive thyroid medication.

Thoughts of suicide and worsening of your depression

If you are depressed, you can sometimes have thoughts of harming or killing themselves. 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.

Tell your doctor if you have, or have had in the past, any medical problems, especially if you have

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
schizophrenia
severe liver disease
severe heart disease
pylorus stenosis (narrowing of the gastric outlet) and paralytic ileus (blocked intestine)
diabetes as you might need an adjustment of your antidiabetic medicine.

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 Oral Solution 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).

Children and adolescents

Depression, neuropathic pain, chronic tension type headache and migraine prophylaxis

Do not give this medicine to children and adolescents aged below 18 years for these treatments as safety and efficacy have not been established in this age group.

Bed-wetting at night

An ECG should be performed prior to initiating therapy with amitriptyline to exclude long QT syndrome
This medicines should not be taking at the same time as an anticholinergic drug (see also section 2 Other medicines and Amitriptyline Oral Solution)
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 enuresis.

Other medicines and Amitriptyline Oral Solution

Some medicines may affect the action of other medicines and this can sometimes cause serious side effects.

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, such as:

monoamine oxidase inhibitors (MAOIs) e.g. phenelzine, iproniazid, isocarboxazid, nialamide or tranylcypromine (used to treat depression) or selegiline (used to treat Parkinson’s disease). These should not be taken at the same time as Amitriptyline Oral Solution (see section 2 Do not take Amitriptyline Oral Solution)
adrenaline, ephedrine, isoprenaline, noradrenaline, phenylephrine and phenylpropanolamine (these may be present in cough or cold medicine, and in some anaesthetics)
medicine to treat high blood pressure for example calcium-channel blockers (e.g. diltiazem and verapamil), guanethidine, betanidine, clonidine reserpine and methyldopa
anticholinergic drugs such as certain medicines to treat Parkinsons disease and gastrointestinal disorders (e.g. atropine, hyoscyamine)
thioridazine (used to treat schizophrenia)
tramadol (painkiller)
medicines to treat fungal infections (e.g. fluconazole, terbinafine, ketoconazole, and itraconazole)
sedatives (e.g. barbiturates)
antidepressants (e.g. SSRIs (fluoxetine, paroxetine, fluvoxamine), duloxetine and bupropion)
medicines for certain heart conditions (e.g. beta blockers and antiarrhythmics)
cimetidine (used to treat stomach ulcers)
methylphenidate (used to treat ADHD)
ritonavir (used to treat HIV)
oral contraceptives
rifampicin (to treat infections)
phenytoin and carbamazepine (used to treat epilepsy)
St. John’s Wort (hypericum perforatum) – a herbal remedy used for depression
thyroid medication
valproic acid.

You should also tell your doctor if you take or have recently taken medicine that may affect the heart’s rhythm. e.g.:

medicines to treat irregular heartbeats (e.g. quinidine and sotalol)
astemizole and terfenadine (used to treat allergies and hayfever)
medicines used to treat some mental illnesses (e.g. pimozide and sertindole)
cisapride (used to treat certain types of indigestion)
halofantrine (used to treat malaria)
methadone (used to treat pain and for detoxification)
diuretics (“water tablets” e.g. furosemide).

If you are going to have an operation and receive general or local anaesthetics, you should tell your doctor that you are taking this medicine.

Likewise, you should tell your dentist that you take this medicine if you are to receive a local anaesthetic.
