1. Why am I using EXTINE?

EXTINE contains the active ingredient paroxetine (as hydrochloride).

EXTINE belongs to a group of medicines called selective serotonin reuptake inhibitor (SSRI) antidepressants. They are thought to work by their action on brain chemicals called amines which are involved in controlling mood.

EXTINE is used to treat:

• Depression which is longer lasting or more severe than the ‘low moods’ that everyone has from time to time. It is thought to be caused by a chemical imbalance in part of the brain that affects your whole body and can cause emotional and physical symptoms. You may feel low in spirit, lose interest in usual activities, have poor appetite, disturbed sleep, wake up early, have low energy and feel guilty over nothing.
• Irrational fears or obsessional behaviour: These can also be due to chemical imbalance in parts of the brain.
• Panic attacks: EXTINE may be used to help prevent panic attacks.
• Patients who may avoid and/or are fearful of social situations.
• Patients with excessive anxiety and worry, and who feel irritable, restless and/or tense in the muscles.
• Repetitive and distressing recollections of a past traumatic event.

2. What should I know before I use EXTINE?

Warnings

In some children and adolescents, treatment with an antidepressant increases suicidal thinking or actions.

• It is important to discuss all the risks of treating depression and also the risks of not treating it. You should discuss all treatment choices with your doctor, not just the use of antidepressants.
• Patients (and caregivers of patients) need to monitor for any worsening of their condition and/or the emergence of thoughts of suicide or suicidal behaviour or thoughts of harming themselves and to seek medical advice immediately if these symptoms present (see Section 2. What should I know before I use EXTINE – Children and Adolescents).

There is an increased risk of breaking a bone in people taking medicines like EXTINE. This risk is greatest during the early stages of treatment.

Do not use EXTINE if:

• you are allergic to paroxetine, or any of the ingredients listed at the end of this leaflet. Always check the ingredients to make sure you can use this medicine.
• you are pregnant or intend to become pregnant.
• you have taken EXTINE before and became unwell, tell your doctor or pharmacist before taking the first dose.
• you are taking any other medications for the treatment of depression or have done so in the last 2 weeks. Taking EXTINE with another antidepressant may cause a serious reaction.
• You must not take EXTINE until 2 weeks after stopping monoamine oxidase inhibitor drugs (MAOIs). Examples of MAOIs are phenelzine and tranylcypromine. Another MAOI includes the antibiotic linezolid. There may be others so please check with your doctor. Taking EXTINE with a MAOI may cause a serious reaction.
• you are taking or have recently taken (within the last two weeks) a medicine called methylthioninium chloride (methylene blue).
• you are taking thioridazine for the treatment of schizophrenia.
• you are taking pimozide.
• the expiry date (EXP) printed on the pack has passed.
• the packaging is torn or shows signs of tampering.

Check with your doctor if you:

• you are allergic to foods, dyes, preservatives or any other medicines.
• have any other medical conditions such as:
  – liver problems
  – heart problems
  – kidney problems
  – epilepsy
  – mania
  – raised pressure in the eye
  – problems with blood clotting
  – other psychiatric conditions (bipolar disorder)
  – diabetes
  – history of bleeding disorders, such as after childbirth
• you are pregnant or intend to become pregnant.
• you are breastfeeding or wish to breastfeed. Your doctor will discuss with you the possible risks and benefits of using EXTINE during breastfeeding.

The signs of an allergic reaction are wheezing, swelling of the lips/mouth, difficulty in breathing, hayfever, lumpy rash (hives) or fainting.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

• If you take EXTINE near the end of your pregnancy, there may be an increased risk of heavy vaginal bleeding shortly after birth, especially if you have a history of bleeding disorders.
• Your doctor or midwife should be aware that you are taking EXTINE so they can advise you.
• Studies show that use of paroxetine in early pregnancy (first 13 weeks) may be associated with an increased risk of some birth defects in babies.
• If you become pregnant or intend to become pregnant while taking paroxetine, you should make an appointment to see your doctor and have your treatment reviewed.
• It is important that you do not stop taking paroxetine suddenly.
• Paroxetine is a medicine that can have withdrawal side effects if stopped suddenly.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

Fertility

Medicines like EXTINE may affect your sperm. Fertility in some men may be reduced while taking EXTINE.

Elderly

Take special care with EXTINE if you are over 65 years of age as EXTINE may cause a reduction in the amount of sodium within your blood which can lead to sleepiness and muscle weakness. If you experience these symptoms, please consult your doctor as soon as possible.

Children and adolescents

EXTINE is not recommended for use in children and adolescents under 18 years.

• The use of EXTINE is not recommended to treat depression in children and adolescents under 18, as the drug has not been shown to be effective in this age group and there are possible unwanted effects.
• Information from clinical trials has suggested that young adults, particularly those with depression, may be at an increased risk of suicidal behaviour (including suicide attempts) when treated with EXTINE, especially during initial treatment (generally the first one to two months).
• The majority of attempted suicides in clinical trials in depression involved patients aged 18 to 30 years.
• Family and caregivers of children and adolescents being treated with antidepressants for major depressive disorder or for any other condition (psychiatric or non-psychiatric) need to monitor them for the emergence of agitation, irritability, unusual changes in behaviour, as well as the emergence of thoughts of suicide, and to report such symptoms immediately to their doctor.
• It is particularly important that monitoring be undertaken during the initial few months of antidepressant treatment or at times of dose increase or decrease.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with EXTINE and affect how it works. In particular tell your doctor if you are taking any of the following medicines which:

• treat depression, anxiety, schizophrenia or attention deficit hyperactivity disorder (ADHD) such as tryptophan, hypericum perforatum (St John’s Wort), perphenazine, risperidone, lithium or atomoxetine.
• are used in anaesthesia or to treat pain or chronic pain, specifically tramadol or fentanyl.
• lower blood pressure or treat heart conditions, such as metoprolol or flecainide.
• control epilepsy (anti-convulsants), such as phenytoin, carbamazepine, phenobarbital.
• thin blood (anti-coagulants), such as warfarin, aspirin, non-steroidal anti-inflammatory drugs (NSAIDs).
• treat Parkinson’s disease, such as selegiline, procyclidine.
• treat stomach ulcers, such as cimetidine.
• treat migraine attacks such as sumatriptan.
• treat or prevent breast cancer, specifically tamoxifen.
• treat HIV infection such as a combination of fosamprenavir and ritonavir.
• Used in anaesthesia, such as mivacurium and suxamethonium.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect EXTINE.

4. How do I use EXTINE?

How much to use

• The usual dose of EXTINE for depression, social anxiety disorder/social phobia, generalised anxiety disorder or post-traumatic stress disorder is one 20 mg tablet per day. Your doctor may increase the dose slowly over several weeks. This may require you to break the tablet in half.
• To treat obsessions and compulsions or panic attacks, the usual dose of EXTINE is two 20 mg tablets per day. Your doctor may start you on a lower dose (half a tablet) and increase the dose slowly over several weeks. This may require you to break the tablet in half.
• Follow the instructions provided and use EXTINE until your doctor tells you to stop.

When to take EXTINE

• EXTINE should be taken in the morning, preferably with food.

How to take EXTINE

• Take EXTINE with a full glass of water or another liquid.

How long to take EXTINE

Keep taking your EXTINE for as long as your doctor tells you.

Your doctor may decide that you should continue to use EXTINE for some time, even when you have overcome your problem. For best effect EXTINE must be taken regularly.

Your doctor will tell you when and how EXTINE should be discontinued.

Your doctor will usually recommend that you stop treatment by slowly reducing the dosage over a period of several weeks. When you stop treatment with EXTINE, especially if this is done suddenly, you may experience unwanted symptoms. Please see the Section 6. Are there any side effects?

If you forget to use EXTINE

• Do not take an extra dose. Wait until the next day and take your normal dose then.

You should immediately:

• phone the Poisons Information Centre
  (by calling 13 11 26), or
• contact your doctor, or

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using EXTINE?

Things you should do

Call your doctor straight away if you:

For any reason, have not taken your medicine exactly as directed. Otherwise, your doctor may think that it was not working as it should and change your treatment unnecessarily.

Like other drugs of this type, EXTINE will not relieve your symptoms straight away. People generally start feeling beter in a few weeks or so. Occasionally, the symptoms of depression or other psychiatric conditions may include thoughts of harming yourself or commiting suicide. It is possible that these symptoms may continue or increase until the full antidepressant effect of your medicine becomes apparent.

All thoughts of suicide must be taken seriously. Tell your doctor immediately or go to the nearest hospital if you have any distressing thoughts or experiences during this initial period or at any other time.

Also contact your doctor if you experience any worsening of your depression/other symptoms at any time during your treatment.

Tell your doctor or go to the hospital immediately if you experience symptoms of serotonin syndrome or neuroleptic malignant syndrome, which are rare life-threatening conditions. These symptoms include high body temperature, stiffness, involuntary muscle jerks, confusion, extreme agitation, delirium and coma.

Remind any doctor, dentist or pharmacist you visit that you are using EXTINE.

Things you should not do

• Do not stop using this medicine suddenly.
• Do not give this medicine to anyone else, even if their symptoms seem similar to yours.
• Do not use EXTINE to treat any other complaints unless your doctor says to.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how EXTINE affects you.

Tests have shown that EXTINE does not have a marked effect on driving ability. However, EXTINE may cause drowsiness, dizziness or lightheadedness in some people. Make sure you know how you react to EXTINE before you drive a car or operate machinery.

Drinking alcohol

Tell your doctor if you drink alcohol.

Although drinking moderate amounts of alcohol is unlikely to affect your response to EXTINE, it is best to avoid alcohol while you are taking this medicine.

Looking after your medicine

• Keep your tablets in the blister pack until it is time to take them.
• Keep the pack in a cool dry place.
• Do not leave it in the car on a hot day.

Keep it where young children cannot reach it, such as in a locked cupboard.

Stopping treatment

Do not stop taking EXTINE even if you begin to feel beter.

Your doctor may decide that you should continue to use EXTINE for some time, even when you have overcome your problem. For best effect EXTINE must be taken regularly.

Your doctor will tell you when and how EXTINE should be discontinued.

When your doctor decides that you should stop taking EXTINE the dose may be reduced slowly or the time between doses increased over 1 or 2 weeks. Some people may have symptoms such as dizziness, anxiety, sleep disturbances, pins and needles, electric shock sensations or feeling sick and sweating if EXTINE is stopped, particularly if stopped suddenly.
