1. What Nortriptyline Tablets are and what are they used for

Nortriptyline Tablets contain the active ingredient nortriptyline hydrochloride, which is a tricyclic antidepressant. Nortriptyline Tablets are used to treat major depression in adults.

2. What you need to know before you take Nortriptyline Tablets
Do not take Nortriptyline Tablets if:
  • you are allergic (hypersensitive) to nortriptyline or any of the other ingredients of Nortriptyline Tablets (see list of ingredients in Section 6). An allergic reaction may include rash, itching, difficulty breathing or swelling of the face, lips, throat or tongue;
  • you have had a recent heart attack or heartbeat disorder, heart block or coronary artery disease;
  • you are taking, or have stopped taking within the last 14 days, a monoamine oxidase inhibitor (e.g. phenelzine, isocarboxazid or tranylcypromine). If you are taking moclobemide you must stop this at least 24 hours before starting nortriptyline.
    You have to stop treatment with Nortriptyline Tablets and wait for 14 days before you start treatment with a monoamine oxidase inhibitor.

Warnings and precautions

Talk to your doctor before taking these tablets if

  • you feel suicidal or aggressive;
  • you are agitated, overactive, or suffer from schizophrenia;
  • you have heart disease;
  • you have a thyroid condition or receive thyroid medication;
  • you have a history of epilepsy;
  • you have high pressure in the eyes (glaucoma);
  • you have an enlarged prostate;
  • you are going to have electroconvulsive therapy (electric shock);
  • you are diabetic as you might need and adjustment of your antidiabetic medicine;
  • you are going to receive an anaesthetic, e.g. for an operation – tell your doctor as it might be necessary to stop the treatment with nortriptyline before you are given anaesthetics;
  • you have had an allergic reaction to another tricyclic antidepressant in the past;
  • you have difficulty in passing urine;
  • you have bipolar disorder as some patients may enter into a manic phase;
  • you have pylorus stenosis (narrowing of the gastric outlet) and paralytic ileus (blocked intestine);
  • you have excessive fever (hyperpyrexia);
  • you are elderly as you 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).
  • you have severe liver disease;
  • you have a cardiac condition called Brugada syndrome.

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 Nortriptyline. 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.

Thoughts of suicide and worsening of your depression

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 adults aged less than 25 years 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 is getting worse, or if they are worried about changes in your behaviour.

Children and adolescents

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.

Other medicines and Nortriptyline Tablets

  • monoamine oxidase inhibitors (MAOIs) e.g. moclobemide, 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 Nortriptyline tablets (see section 2 Do not take nortritptyline tablets)
  • adrenaline, ephedrine, isoprenaline, noradrenaline, phenylephrine and phenylpropanolamine (these may be present in cough or cold medicine, and in some anaesthetics)

Taking Nortriptyline Tablets with alcohol

You should not drink alcohol while you are being treated with Nortriptyline Tablets as alcohol might increase the sedative effect.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Nortriptyline should not be used during pregnancy unless your doctor considers it clearly necessary and only after careful consideration of the benefit and risk. If you have taken this medicine during the last part of the pregnancy, the newborn may have withdrawal symptoms such as irritability, increased muscle tension, tremor, irregular breathing, poor drinking, loud crying, urinary retention, and constipation.

Your doctor will advise you whether to start/continue/ stop breast-feeding, or stop using this medicine taking into account the benefit of breast-feeding for your child and the benefit of therapy for you.

Do not drive or use machinery when you are on Nortriptyline Tablets unless you are sure your judgement and co-ordination are not affected. Antidepressants may affect your ability to drive or to operate machinery safely.

3. How to take Nortriptyline Tablets

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

  • The recommended adult dose is 25mg three or four times daily or the dose may be given once a day, usually at night. The dose should begin at a low level, 10mg, 3-4 times daily, for example and be increased gradually as required. The maximum dose is 150mg per day.
  • If your doctor tells you to take more than four 25mg tablets a day, he or she may arrange for you to have regular blood tests.

The elderly:

The usual dose is 30 to 50mg/day in divided doses.

Treatment may start at a low level (10-20 mg daily) and may be increased as required to the maximum dose of 50mg. If you require a dose of 50mg or over, your doctor will arrange for you to have a recording of your heart (ECG) and blood tests.

The 50mg tablets are not appropriate for use in elderly patients.

Renal impairment

In case of renal impairment, your doctor will increase or decrease the dose carefully and gradually. In most cases, however, the usual dosage will be given.

Hepatic impairment

Patients with liver diseases or people known as “poor metabolisers” usually receive lower doses. Your doctor may take blood samples to determine the level of noritriptyline in the blood.

Use in children and adolescent patients:

Nortriptyline Tablets should not be used in children and adolescents aged less than 18 years, as safety and efficacy have not been established.

Lower dosages are recommended for outpatients than for patients in hospital who will be under close supervision.

Duration of treatment

It may take a few weeks before you feel any improvement.

Following remission, maintenance treatment may be needed longer term, usually up to 6 months. This should be at the lowest dose that stops the symptoms of depression coming back.

If you take more Nortriptyline Tablets than you should

Do not take more tablets than your doctor tells you to. If you ever take too many, or if a child has taken any nortriptyline, go to the nearest hospital casualty department or tell your doctor at once.

Symptoms of overdose include blurred vision, fast or irregular heartbeats, difficulties passing water, dry mouth and tongue, intestinal blockage, fits, fever, agitation, confusion, hallucinations, uncontrolled movements, low blood pressure, weak pulse, pallor, difficulty breathing, blue discolouration of the skin, decreased heart rate, drowsiness, loss of consciousness, coma, various cardiac symptoms such as heart block, heart failure, cardiogenic shock, metabolic acidosis, hypokalaemia.

An overdose can be very dangerous.

If you forget to take Nortriptyline Tablets

If you forget to take a dose, take it as soon as you remember. If it is almost time for your next dose do not take a double dose to make up for a forgotten dose, just carry on as before. If you have missed several doses, discuss this with your doctor.

If you stop using Nortriptyline Tablets

Antidepressants may not make you feel better for the first two weeks or more of treatment, so keep taking Nortriptyline Tablets until your doctor tells you to stop. Do not stop these tablets without discussing it with your doctor first.

If you stop using Nortriptyline Tablets abruptly after prolong therapy you may have withdrawal symptoms, including not being able to sleep, headache, nausea, irritability and sweating.
