unable to enjoy life, poor appetite or overeating, disturbed sleep, often waking up
early, loss of sex drive, lack of energy and feeling guilty over nothing.

How to take Axit
Follow all directions given to you by your doctor and pharmacist carefully.
They may differ from the information contained in this leaflet.
How much to take
Your doctor will tell you how much Axit to take each day. Take exactly the amount
your doctor tells you.
The usual starting dose is 15 mg per day. Your doctor may slowly increase this dose
depending on how you respond to this medicine. The effective dose for most people
is usually between 30 and 45 mg daily.
Your doctor may have prescribed a different dose.
If you do not understand the instructions on the box, ask your doctor or pharmacist
When to take it
Take your medicine at about the same time each day.
Your doctor will tell you when to take your tablets.
The tablet(s) should be taken at the same time each day, preferably as a single night-time
dose before going to bed; if recommended by your doctor, Axit may be taken in sub-doses
equally divided over the day (once in the morning and once at night-time before going
How to take it
Swallow the tablet(s), without chewing, together with some water or other fluid.
Do not crush or chew the tablets.
Axit 15 and Axit 30 tablets can be divided in half along the breakline, if advised
by your doctor or pharmacist.
Axit can be taken with or without food.
How long to take it
Keep taking Axit until your doctor tells you to stop.
For depression, the length of treatment will depend on how quickly your symptoms improve.
Most antidepressants take time to work, so do not be discouraged if you don't feel
better right away. Some of your symptoms may improve in 1 to 2 weeks but it can take
up to 2 - 4 weeks longer to feel the full benefit of the medicine.
Even when you feel well, you will usually have to take Axit for 4 to 6 months or even
longer to make sure the benefits will last.
If you forget to take it
ONCE DAILY DOSING
If you forget to take the tablet before you go to bed, do not take the missed dose
the next morning. It may cause drowsiness or sleepiness during the day. Continue treatment
in the evening with your normal dose.
TWICE DAILY DOSING
Morning dose forgotten - simply take it together with your evening dose.
Evening dose forgotten - do not take it with the next morning dose. Continue treatment
with your normal morning and evening doses.
Both doses forgotten - do not try to make up for the missed tablets. Continue with
your usual morning and evening dose the next day.
If you have trouble remembering to take your medicine, ask your pharmacist for some
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13
11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you
think you or anyone else may have taken too much Axit. Do this even if there are no
signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too many Axit tablets, you may feel drowsy, dizzy, confused and agitated.
You may also have changes to your heart rhythm (fast, irregular heartbeat) and/or

While you are taking Axit
Things you must do
Tell your doctor immediately if you develop fever, chills, sore throat or mouth ulcers
or other signs of frequent infections. Stop taking Axit and consult with your doctor
for a blood test.
In rare cases Axit can cause disturbances in the production of blood cells (bone marrow
depression). Some people become less resistant to infection because Axit can cause
a temporary shortage of white blood cells (granulocytopenia). In rare cases Axit can
also cause a shortage of red and white blood cells, as well as blood platelets (aplastic
anaemia), a shortage of blood platelets (thrombocytopenia) or an increase in the number
of white blood cells (eosinophilia). While rare, these symptoms most commonly appear
after 4 - 6 weeks of treatment.
Tell your doctor immediately or go to the nearest hospital for treatment if you have
any suicidal thoughts or other mental/mood changes.
Occasionally, the symptoms of depression or other psychiatric conditions may include
thoughts of harming yourself or committing suicide. Until the full antidepressant
effect of your medicine becomes apparent, it is possible these symptoms may increase
in the first few weeks of treatment.
Information from clinical trials have shown an increased risk of suicidal behaviour
in young adults aged less than 25 years with psychiatric conditions who were treated
with an antidepressant.
If you or someone you know is showing warning signs of suicide-related behaviour while
taking Axit, contact your doctor or a mental health professional right away or go
to the nearest hospital for treatment. These signs include:
thoughts or talk about death or suicide
thoughts or talk of self-harm or harm to others
any recent attempts of self harm
increase in aggressive behaviour, irritability or agitation.
All mentions of suicide or violence must be taken seriously.
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.
Tell your doctor if you become pregnant while taking this medicine. Do not stop taking
your tablets until you have spoken to your doctor.
If you use Axit until, or shortly before birth, your baby should be supervised for
possible adverse effects.
