WHAT VALDOXAN IS USED FOR
VALDOXAN is used in the treatment of depression or to help prevent depression returning,
and is only available with a doctor's prescription. The symptoms of depression vary
from one person to another, but commonly include persistent sadness, loss of interest
in favourite activities, feelings of worthlessness, sleep problems, feeling of being
slowed down, feelings of anxiety or changes in appetite and weight. Changes in your
daily sleep and appetite patterns are examples of disturbances of your 'body clock'
that occur commonly in depression.
VALDOXAN can help regulate your 'body clock' (circadian rhythm) with positive benefits
on mood and sleep in depression.
VALDOXAN is not addictive.
In clinical studies VALDOXAN had no effect on sexual function.
VALDOXAN is not recommended for children, adolescents (under 18 years old) or elderly
patients aged 75 or older.
Your doctor may prescribe VALDOXAN for another purpose. Ask your doctor if you have
any questions about why VALDOXAN has been prescribed for you.
BEFORE YOU TAKE VALDOXAN
There are some people who shouldn't take VALDOXAN. Please read the list below. If
you think any of these situations apply to you or you have any questions, please see

at the end of this leaflet
the packaging is torn or shows signs of tampering
the expiry date (EXP) printed on the pack has passed.
Before you start to take VALDOXAN
A routine blood test should be performed before treatment to check how your liver
is functioning. If you have increased levels of liver enzymes your doctor will decide
if VALDOXAN is right for you.
You may be at risk of liver problems if you are overweight, obese or have diabetes
or if you are taking medicines known to affect your liver (ask your doctor if you
are unsure which medicines these might be).
Tell your doctor if you have ever experienced or develop an episode of bipolar disorder,
mania or hypomania (extreme upward mood swings or irritable mood).
Your doctor should be made aware if you have a history of dementia.
Tell your doctor if you are pregnant, plan to become pregnant or are breast-feeding.
Talk to your doctor about how much alcohol you drink. People who drink excessive quantities
of alcohol should not take VALDOXAN. Excessive alcohol may cause liver problems and
may make depression worse.
Tell your doctor if you are smoking more than 15 cigarettes/day.
If you have any doubts or questions about taking VALDOXAN consult with your doctor.
Taking other medications

buy without a prescription from a pharmacy, supermarket, health food shop or naturopath/herbalist.
Tell your doctor if you are taking propranolol (a medicine sometimes used to treat
HOW TO TAKE VALDOXAN
Always take VALDOXAN exactly as your doctor has told you. You should check with your
doctor or pharmacist if you are not sure.
Swallow VALDOXAN tablets whole with some water in the evening at bedtime.
VALDOXAN can be taken with or without food.
How much to take
The usual dose of VALDOXAN is one tablet in the evening at bedtime. In some cases
your doctor may prescribe two tablets (50 mg) to be taken together in the evening
at bedtime. You should not take more than the maximum recommended dose of 50 mg daily.
Do not change your dose without the advice of your doctor even if you feel better.
How long to take it
Current experience with medications to treat depression shows that treatment for six
months or longer provides the best opportunity of long-term recovery from a first
episode of depression. For those who have previously had depression, a longer period
of treatment will usually be recommended.
With VALDOXAN, some people experience improvements in mood and sleep within two weeks
of starting treatment. As people respond differently to medications, do not become
discouraged if you do not notice a difference right away.
Continue taking VALDOXAN until your doctor advises you to stop. Even when you are
feeling better, your doctor would usually continue to give you VALDOXAN for some time
to help to prevent your depression from returning.
If you forget to take it
If you forget to take your VALDOXAN skip the dose you missed, take your next planned
dose at the usual time and continue as normal.
To avoid confusion, it is recommended that you leave the tablet you missed in the
tablet strip and continue on with the next day's tablet as indicated on the tablet
Do not try to make up for missed doses. Simply take one dose per day.
The calendar printed on the tablet strip should help you remember when you last took
a VALDOXAN tablet. It is also a good reminder of how much VALDOXAN you have left so
you can get your prescription refilled if you need to.
If you take too much (overdose)
It is important that you do not take more VALDOXAN tablets than your doctor has prescribed.
The experience of overdoses with VALDOXAN is limited but reported symptoms include
stomach pain, drowsiness, tiredness, agitation, anxiety, dizziness, blue-ish discolouration
of the skin or mucous membranes and/or a general feeling of being unwell.
If you do take more than you have been prescribed, contact your doctor immediately
If anyone accidentally swallows any of your VALDOXAN tablets, call your nearest Poisons
Information Centre for advice (Australian telephone: 13 11 26), or go to Accident
and Emergency at your nearest hospital. Keep the telephone number for these places
handy whilst taking any medications.
WHILE YOU ARE TAKING VALDOXAN
Your liver function
VALDOXAN is processed by the liver. Before you started taking VALDOXAN a blood test
was required to check your liver function. While you are taking VALDOXAN you will
need further blood tests to check your liver continues to function properly. These
tests should be performed:
before the start of treatment and before a dose increase to 50mg (dose should only
be increased by your doctor).
and then around:
12 weeks and
These blood test results will help your doctor decide whether VALDOXAN is suitable
for you. VALDOXAN may sometimes affect the results of these blood tests.
You may also have tests to check that your liver is working properly if you start
to take medicines that interfere with how the body processes VALDOXAN.
Talk to your doctor about how much alcohol you drink.
Things you must do
To make sure you have the best opportunity of long-term recovery from your depression,
continue to take VALDOXAN as long as your doctor recommends you to.
Tell your doctor if you have experienced or develop an episode of bipolar disorder,
mania or hypomania (extreme upward mood swings or irritable mood).
Check with your doctor that your liver function tests are done as described in the
YOUR LIVER FUNCTION section above.
Seek advice from your doctor immediately if you develop signs or symptoms of potential
liver problems (such as dark urine, light coloured faeces, yellow skin or eyes, pain
in your upper right abdomen, new-onset and unexplained fatigue). Your doctor may advise
you to stop taking VALDOXAN.
Tell your doctor immediately if you become pregnant while taking VALDOXAN.
Tell all doctors, dentists and healthcare professionals who are treating you that
you are taking VALDOXAN.
Do not take any other medications, whether they require a prescription or not, without
first telling your doctor that you are taking VALDOXAN as sometimes the action of
one medicine may interfere with another.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed.
Otherwise, your doctor may think that it was not effective and change your treatment
Tell your doctor if you feel the tablets are not helping your condition.
Keep all of your doctor's appointments so that your progress can be checked.
If you are being treated for depression, be sure to discuss with your doctor any problems
you may have and how you feel, especially any feelings of severe sadness or bursts
of unusual energy or anger.
If you have any thoughts about suicide or doing harm to yourself call your doctor
immediately and also contact someone you trust.
All thoughts or talk about suicide or violence towards others or yourself are serious.
Such thoughts may even occur after commencing antidepressant treatment, particularly
before the full antidepressant effect is seen. Such thoughts are more likely to occur
in young adults under 25 years of age.
If you or someone you know is showing any of the following common warning signs, either
contact your doctor or healthcare professional or go to the nearest hospital for treatment:
worsening of your depression
thoughts or talk about death or suicide
thoughts or talk about self-harm or doing harm to others
any recent attempts of self-harm
an increase in aggressive behaviour, irritability or agitation.

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.

You should not take VALDOXAN together with certain medications (see also under "When
you must not take VALDOXAN") such as: fluvoxamine (another medicine used in the treatment
of depression) or ciprofloxacin (an antibiotic).

or if they have the same condition as you.
