Patient leaflet - Nortriptyline 10 mg film-coated tablets

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

Nortriptyline tablets contain the active substance nortriptyline hydrochloride, which is a tricyclic antidepressant. Nortriptyline tablets relieve symptoms of depression in adults.

2. What you need to know before you take Nortriptyline tablets

Do not take Nortriptyline tablets

Ÿ If you are allergic to nortriptyline hydrochloride or any of the other

ingredients of this medicine (listed in section 6). An allergic reaction may include rash, itching, difficulty breathing or swelling of the face, lips, throat or tongue.

Ÿ If you have had a recent heart attack or heartbeat disorder. Ÿ If you have severe liver disease.

Ÿ If you suffer from mania (abnormally raised mood).

Ÿ If you are breast-feeding.

Ÿ If the child is under 6 years of age.

Ÿ If you are taking, or have taken in the last two weeks, monoamine

oxidase inhibitors (another type of antidepressant).

Ÿ If you are taking adrenaline-like drugs including ephedrine, isoprenaline,

noradrenaline, phenylephrine and phenylpropanolamine. These drugs are often contained in cough and cold remedies.

Warnings and precautions

Talk to your doctor or pharmacist before taking Nortriptyline tablets Ÿ If you feel suicidal or aggressive – tell your doctor.

Ÿ If you are agitated, overactive or suffer from schizophrenia. Ÿ If you have heart disease.

Ÿ If you have a cardiac condition called Brugada syndrome. Ÿ If you have a thyroid condition.

Ÿ If you have a history of epilepsy.

Ÿ If you have high pressure in the eyes (glaucoma).

Ÿ If you have an enlarged prostate.

Ÿ If you are going to have electroconvulsive therapy (electric shock). Ÿ If you are diabetic.

Ÿ If you are going to receive an anaesthetic, e.g. for an operation – tell

your doctor.

Ÿ If you have had an allergic reaction to another tricyclic antidepressant in

the past.

Ÿ If you are pregnant, think you might be pregnant or planning to become

pregnant or are breastfeeding, you should not take Nortriptyline tablets unless your doctor tells you to.

The use of Buprenorphine together with Nortriptyline tablets can lead to serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Nortriptyline tablets”).

Children and adolescents

Nortriptyline should not be used in the treatment of depression in children and adolescents under the age of 18 years.

Thoughts of suicide and worsening of your depression or anxiety disorder

If you are depressed and/or have anxiety disorders 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:

Ÿ If you have previously had thoughts about killing or harming yourself. Ÿ 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 hospital straight away.

You may find it helpful to tell a relative or close friend that you are depressed or have an anxiety disorder, 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. If any of the above applies to you, tell your doctor or pharmacist.

Other medicines and Nortriptyline tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

The following medicines may interact with your Nortriptyline tablets: Ÿ guanethidine, debrisoquine, bethanidine, clonidine (used to treat high blood pressure)

Ÿ barbiturates (used for anxiety or to make you feel sleepy) Ÿ alcohol (you should not drink alcohol)

Ÿ fluoxetine (another antidepressant)

Ÿ cimetidine (for heartburn and ulcers)

Ÿ phenothiazines (for mental illness)

Ÿ carbamazepine (for epilepsy)

Ÿ propafenone, flecainide, encainide, quinidine (for heartbeat disorders) Ÿ valproic acid (medicine used for the treatment of epilepsy and bipolar disorder)

Ÿ buprenorphine/opioids: These medicines may interact with Nortriptyline tablets and you may experience symptoms such as involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, hallucinations, coma, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension, body temperature above 38°C. Contact your doctor when experiencing such symptoms. It may still be alright for you to be given Nortriptyline tablets. Your doctor will be able to decide what is suitable for you.
