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

Amitriptyline Hydrochloride Tarbis contains the active substance amitriptyline, which 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 a response has not 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 Tarbis

Do not take Amitriptyline Hydrochloride Tarbis:

• 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 had 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 day before
• if you have severe liver disease

If you are taking amitriptyline hydrochloride, 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.

Severe skin reactions, including drug reactions with eosinophilia and systemic symptoms (DRESS), have been reported in association with amitriptyline treatment. Discontinue use of amitriptyline and seek medical attention immediately if you observe any of the symptoms related to these severe skin reactions described in section 4.

The use of buprenorphine/opioids with amitriptyline hydrochloride may cause serotonin syndrome, a potentially life-threatening condition (see "Taking Amitriptyline Hydrochloride Tarbis with other medicines")

Cardiac arrhythmias 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 cardiac arrhythmias (fast or irregular heartbeat) have been reported with amitriptyline hydrochloride. Inform 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 condition called heart failure)
• you are taking any other medication 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 medication for your thyroid

Suicidal thoughts and worsening of depression

If you are depressed, you may sometimes have thoughts of harming or killing yourself. These thoughts may increase when you first start taking antidepressants, as all these medicines take time to work, usually around 2 weeks, but sometimes longer.

You are more likely to have these thoughts:

• If you have had thoughts of killing or harming yourself in the past.
• If you are a young adult. Information from clinical trials has shown an increased risk of suicidal behavior 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, 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 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 behavior.

Manic episodes

Some patients with manic-depressive illness may enter a manic phase, characterized by rapid, changing 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 problems, 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 (blockage of the intestine)
• diabetes, as it may be necessary to adjust your antidiabetic medication

If you use antidepressants such as selective serotonin reuptake inhibitors (SSRIs), your doctor may consider changing the dose of your medication (see also section 2 "Taking Amitriptyline Hydrochloride Tarbis with other medicines" and section 3).

Elderly people are more likely to suffer from 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 "Taking Amitriptyline Hydrochloride Tarbis with other medicines")
• 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

Other medicines and Amitriptyline Hydrochloride Tarbis

Some medicines may affect the way other medicines work and sometimes this can 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) such as, e.g., phenelzine, iproniazid, isocarboxazid, nialamide, or tranylcypromine (used to treat depression) or selegiline (used to treat Parkinson's disease). These medicines should not be taken at the same time as amitriptyline hydrochloride (see section 2 "Do not take Amitriptyline Hydrochloride Tarbis")
• adrenaline, ephedrine, isoprenaline, noradrenaline, phenylephrine, and phenylpropanolamine (which may be present in cough and cold medicines and in some anesthetics)

• anticholinergic drugs such as certain medicines for Parkinson's disease and gastrointestinal disorders (e.g., atropine, hyoscine)
• thioridazine (used to treat schizophrenia)
• tramadol (for pain relief)
• medicines for fungal infections (e.g., fluconazole, terbinafine, ketoconazole, and itraconazole)
• sedatives (e.g., barbiturates)
• Buprenorphine/opioids. These medicines may interact with amitriptyline hydrochloride, and you may experience symptoms such as involuntary muscle contractions, including muscles that control eye movement, agitation, hallucinations, coma, excessive sweating, tremors, exaggerated reflexes, increased muscle tension, and body temperature above 38°C. Contact your doctor if you experience these symptoms.
• antidepressants (e.g., SSRIs [fluoxetine, paroxetine, fluvoxamine], duloxetine, and bupropion)
• medicines for certain heart conditions (e.g., beta-blockers and antiarrhythmics)

Also, tell your dentist that you are taking this medicine if you are going to receive a local anesthetic.
