2. What you need to know before you take Tryptizol

Do not take Tryptizol:

• 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 heartbeat (arrhythmias) detected on 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 Tryptizol, 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

Talk to your doctor or pharmacist before you start taking Tryptizol.

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.

The use of Buprenorphine or Buprenorphine/naloxone with Tryptizol may cause serotonin syndrome, a potentially life-threatening condition (see “Taking Tryptizol with other medicines”)

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

QT interval prolongation

A heart problem called “QT interval prolongation” (which appears on the electrocardiogram [ECG]) and heart rhythm disorders (fast or irregular heartbeat) have been reported with Tryptizol. 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 the 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 around 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) 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 package 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 that you 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 crises
• 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 use antidepressants such as selective serotonin reuptake inhibitors (SSRIs), your doctor may consider changing the dose of your medicine (see also section 2 “Taking Tryptizol with other medicines” and section 3).

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, prophylaxis of chronic tension-type headache, and prophylaxis of migraine

Do not give this medicine to children and adolescents under 18 years 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 Tryptizol 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

Taking Tryptizol with other medicines

Some medicines may affect the way other medicines work 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) 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 Tryptizol (see section 2 “Do not take Tryptizol”)
• adrenaline, ephedrine, isoprenaline, noradrenaline, phenylephrine, and phenylpropanolamine (which may be present in cough and cold medicines and some anesthetics)

• medicines to treat high blood pressure, such as, e.g., calcium channel blockers (e.g., diltiazem and verapamil), guanethidine, betanidine, clonidine, reserpine, and methyldopa
• 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 to treat fungal infections (e.g., fluconazole, terbinafine, ketoconazole, and itraconazole)
• sedatives (e.g., barbiturates)
• Buprenorphine or Buprenorphine/naloxone. These medicines may interact with Tryptizol, 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)
• cimetidine (used to treat stomach ulcers)
• methylphenidate (used to treat ADHD)
• ritonavir (used to treat HIV)
• oral contraceptives
• rifampicin (for infections)
• phenytoin and carbamazepine (used to treat epilepsy)
• St. John's Wort (Hypericum perforatum), a herbal medicine used for depression
• thyroid medicines
• valproic acid

You should also tell your doctor if you are taking or have recently taken medicines that may affect heart rhythm, such as:

• medicines to treat irregular heartbeats (e.g., quinidine and sotalol)
• astemizole and terfenadine (used to treat allergies and hay fever)
• medicines used to treat certain 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” such as, e.g., furosemide)

If you are going to have surgery and receive general or local anesthetics, you must tell your doctor that you are taking this medicine.

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