1. What Amitriptyline Hydrochloride Neuraxpharm is and what it is used for

Amitriptyline belongs to a group of medicines called tricyclic antidepressants.

This medicine is used to treat:

• Depression in adults (major depressive episodes)
• Neuropathic pain in adults
• Prevention of chronic tension-type headache in adults
• Prevention of migraine in adults
• Nocturnal enuresis in children aged 6 years and above, only when other organic causes such as spina bifida and related disorders have been excluded and no response has been achieved with other non-pharmacological or pharmacological treatments, including muscle relaxants and desmopressin. This medicine should only be prescribed by doctors with experience in the treatment of patients with persistent urinary incontinence.

2. What you need to know before you take Amitriptyline Hydrochloride Neuraxpharm

Do not take Amitriptyline Hydrochloride Neuraxpharm:

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

If you are taking amitriptyline, you must stop treatment with this medicine and wait 14 days before starting treatment with an MAOI.

This medicine must not be used in children under 6 years of age.

Warnings and precautions

Consult your doctor or pharmacist before starting treatment with Amitriptyline Hydrochloride Neuraxpharm.

Heart rhythm disorders and hypotension may occur if you receive a high dose of amitriptyline. This can also occur with usual doses if you have pre-existing heart disease.

Prolonged QT interval

A heart problem called "prolonged QT interval" (which appears on the electrocardiogram [ECG]) and heart rhythm disorders (fast or irregular heartbeat) have been reported with this medicine. Tell your doctor if:

• you have a slow heart rate
• you have or have had a problem where the heart cannot pump blood to the body as it should (a situation called heart failure)
• you are taking any other medicine that may cause heart problems, or
• you have a problem that causes low potassium or magnesium or high potassium levels in the blood
• you are scheduled for surgery, as it may be necessary to stop treatment with amitriptyline before you are given anesthetics. In case of emergency surgery, the anesthesiologist should be informed about treatment with amitriptyline
• you have an overactive thyroid gland or are taking thyroid medication

Suicidal thoughts and worsening of depression

If you are depressed, you may sometimes think about harming yourself or taking your own life. This type of thought may increase when you first start taking antidepressants, as all these medicines take time to work, usually about two weeks, but sometimes longer.

You are more likely to have these thoughts:

• If you have previously thought about taking your own life or harming yourself.
• If you are a young adult. Clinical trial data have shown an increased risk of suicidal behavior in young adults (less than 25 years old) with psychiatric disorders who were treated with an antidepressant.

If you have thoughts of harming yourself or taking your own life, contact your doctor or go to a hospital immediately.

It may be helpful to tell a relative or close friend that you are depressed and ask them to read this leaflet. You can ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behavior.

Manic episodes

Some patients with manic-depressive illness may enter a manic phase, characterized by rapid, profuse ideas, excessive joy, and excessive physical activity. In these cases, it is essential to contact your doctor, who will probably change your medication.

Tell your doctor if you have or have had any medical problem, especially if you have

• narrow-angle glaucoma (vision loss due to abnormally high pressure in the eye)
• epilepsy, history of seizures or epileptic fits
• difficulty urinating
• enlarged prostate
• thyroid disease
• bipolar disorder
• schizophrenia
• severe liver disease
• severe heart disease
• pyloric stenosis (narrowing of the stomach outlet) and paralytic ileus (intestinal blockage)

• diabetes, as it may be necessary to adjust your antidiabetic medication

If you are taking antidepressants such as selective serotonin reuptake inhibitors (SSRIs), your doctor may consider changing the dose of your medication (see also section 2 "Other medicines and Amitriptyline Hydrochloride Neuraxpharm" and section 3).

Severe skin reactions, including drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported in association with treatment with Amitriptyline Hydrochloride Neuraxpharm. Stop using Amitriptyline Hydrochloride Neuraxpharm and seek medical attention immediately if you notice any of the symptoms related to these severe skin reactions described in section 4.

Elderly people are more likely to experience certain side effects, such as dizziness when standing up due to low blood pressure (see also section 4 "Possible side effects").

Children and adolescents

Depression, neuropathic pain, prevention of chronic tension-type headache, and prevention of migraine.

Do not give this medicine to children and adolescents under 18 years of age for these treatments, as long-term safety and efficacy have not been established for this age group.

Nocturnal enuresis

• An ECG should be performed before starting therapy with amitriptyline to rule out long QT syndrome.
• These medicines should not be taken at the same time as an anticholinergic drug (see also section 2 "Other medicines and Amitriptyline Hydrochloride Neuraxpharm").
• During the early stages of treatment with antidepressants for disorders other than depression, suicidal thoughts and behaviors may also occur; therefore, when treating patients with enuresis, the same precautions should be taken as when treating patients with depression.
