What is AROPAX used for?
The name of your medicine is AROPAX; it is also known as paroxetine.
AROPAX 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.
Depression 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 parts of the brain. This imbalance affects your whole body and can cause emotional and
physical symptoms. You may feel low in spirit, lose interest in usual activities, be unable to enjoy life, have poor appetite
or over eat, have disturbed sleep, often waking up early, low energy and feel guilty over nothing.
AROPAX may also be used to treat irrational fears or obsessional behaviour. These can also be due to chemical imbalance in
parts of the brain.
AROPAX may also be used to help prevent panic attacks.
AROPAX may also be used to treat patients who may avoid and/or are fearful of social situations.
AROPAX may also be used to treat patients who have excessive anxiety and worry, and who feel irritable, restless, and/or tense
in the muscles.
AROPAX may also be used to treat repetitive and distressing recollections of a past traumatic event.
Your doctor may decide that you should continue to use AROPAX for some time, even when you have overcome your problem. This
should prevent the problem from returning.
Your doctor may have prescribed AROPAX for another use. Ask your doctor if you have questions about why AROPAX has been prescribed
for you.
Before you take AROPAX
Antidepressants can increase suicidal thoughts and actions in some children and adolescents younger than 18 years of age.
But suicidal thoughts and actions can also be caused by depression, a serious medical condition that is commonly treated with
antidepressants. Thinking about killing yourself or trying to kill yourself is called suicidality or being suicidal.
Antidepressants are used to treat depression and other illnesses. Depression and other illnesses can lead to suicide. 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 Use In Children and Adolescents).
Do not take if:
You must not take Aropax if:
you are pregnant or intend to become pregnant. 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 (see Unwanted Effects that may occur on stopping treatment).
you have ever had an allergic reaction to paroxetine hydrochloride or any of the ingredients listed toward the end of this
leaflet. (See "Ingredients")
you have taken AROPAX 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 AROPAX with
another antidepressant may cause a serious reaction. You must not take AROPAX until 2 weeks after stopping monoamine oxidase
inhibitor drugs (MAOIs). Examples of MAOIs are phenelzine (Nardil) and tranylcypromine (Parnate). There may be others so
please check with your doctor. Taking AROPAX 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 (Melleril, Aldazine) for the treatment of schizophrenia.
you are taking pimozide (Orap)

the packaging is torn or shows signs of tampering
Take special care with Aropax if you are over 65 years of age as Aropax 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.
Medicines like AROPAX may affect your sperm. Fertility in some men may be reduced while taking AROPAX.

treat HIV infection such as a combination of fosamprenavir and ritonavir
Some medicines may affect the way other medicines work. Your doctor or pharmacist will be able to tell you which medicines
are safe to take with AROPAX.
How do I take Aropax?
Follow your doctors' instructions about how and when to take AROPAX.
Read the direction label carefully. If you have any concerns about how to take AROPAX, talk to your doctor or pharmacist.
How much to take
The usual dose of AROPAX for depression, social anxiety disorder/social phobia, generalised anxiety disorder or post traumatic
stress disorder is one 20mg 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 AROPAX is two 20mg 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.
How to take it
Take AROPAX with a full glass of water or another liquid. AROPAX tablets can be broken in half, but should not be chewed.
AROPAX should be taken in the morning, preferably with food.
How long to take it for
Keep taking your AROPAX for as long as your doctor tells you.
Like other drugs of this type, Aropax will not relieve your symptoms straight away. People generally start feeling better
in a few weeks or so. Occasionally, the symptoms of depression or other psychiatric conditions may include thoughts of harming
yourself or committing suicide. It is possible that these symptoms may continue or increase until the full anti-depressant
effect of your medicine becomes apparent. 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.
Stopping Treatment
Do not stop taking AROPAX even if you begin to feel better. Your doctor may decide that you should continue to use AROPAX
for some time, even when you have overcome your problem. For best effect AROPAX must be taken regularly.
Your doctor will tell you when and how Aropax 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 AROPAX, especially if this is done suddenly, you may experience unwanted symptoms. Please see the
section of this leaflet called "Unwanted Effects that may occur on stopping treatment"
Use in children and adolescents
AROPAX is not recommended for use in children and adolescents under 18 years.
The use of AROPAX 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 AROPAX, 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.
If you forget to take it
Do not take an extra dose. Wait until the next day and take your normal dose then.
Do not try to make up for the dose that you missed by taking more than one dose at a time.
What do I do if I take too much? (Overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 131126) for advice, if you think you or anyone
else may have taken too much Aropax, even if there are no signs of discomfort or poisoning.
If you are not sure what to do, contact your doctor or pharmacist.
While you are taking Aropax
Things you must do
Tell your doctor if, for any reason, you 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.
Things you must not do
Do not give this medicine to anyone else, even if their symptoms seem similar to yours.
Do not use Aropax to treat any other complaints unless your doctor says to.
Things to be careful of
Be careful driving or operating machinery until you know how AROPAX affects you. Tests have shown that AROPAX does not have
a marked effect on driving ability. However, AROPAX may cause drowsiness, dizziness or lightheadedness in some people. Make
sure you know how you react to AROPAX before you drive a car or operate machinery.
Although drinking moderate amounts of alcohol is unlikely to affect your response to AROPAX, it is best to avoid alcohol while
you are taking this medicine.
There is an increased risk of breaking a bone in people taking medicines like AROPAX. This risk is greatest during the early
stages of treatment.
When your doctor decides that you should stop taking AROPAX 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 AROPAX is stopped, particularly if stopped suddenly.
Although Aropax is not recommended for children under 18 years of age, additional symptoms that have been experienced by children
whilst stopping treatment are, abdominal pain, nervousness and mood changes.
What are the side effects?
Check with your doctor as soon as possible if you think you are experiencing any side effects or allergic reactions due to
taking Aropax, even if the problem is not listed below.
Like other medicines, Aropax can cause some side effects. If they occur, they are most likely to be minor and temporary.
However, some may be serious and need medical attention.

These are likely to occur in the first few days of stopping treatment or very rarely if you miss a dose. However, they are
more likely to occur if you stop taking AROPAX too quickly. Therefore always consult your doctor before stopping your medicine.
For the majority of patients, symptoms go away on their own within a few weeks. However, if you feel that the unwanted symptoms
are too severe, see your doctor who will suggest how to manage stopping treatment more slowly.

sweating
hyperactivity
hostile/unfriendly behaviour
