Follow all directions given to you by your doctor and pharmacist.
They may differ from the information contained in this leaflet.
How much to take
Your doctor will tell you how much Avanza SolTab to take each day. Take exactly the
amount your doctor tells you.
The usual starting dose is 15mg per day. Your doctor may slowly increase this dose
depending on how you respond to Avanza SolTab. The effective dose for most people
is usually between 30mg and 45mg per day.
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 Avanza SolTab 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, Avanza SolTab may be taken
in sub-doses equally divided over the day (once in the morning and once at night-time
before going to bed).
How to take it
AVANZA SolTab can be taken with or without water.
Please read the following instructions carefully.
To prevent crushing the tablet, do not push against the tablet pocket.
Each blister contains six tablet pockets, which are separated by perforations (dotted
lines). Bend the strip several times along the dotted lines, and then tear off one
Carefully peel off the lidding foil, starting in the corner indicated by the arrow.
Take out the tablet with dry hands and place it on the tongue. The tablet will rapidly
disintegrate and can be swallowed with or without water.
Take the tablet immediately after it is removed from the tablet pocket.
Once removed it cannot be stored.
How long to take it
Keep taking Avanza SolTab 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 to feel the full benefit of the medicine.
Even when you feel well, you will usually have to take Avanza SolTab for 4 to 6 months
or even longer to make sure the benefits will last.
If you forget to take it

next morning. It may cause drowsiness or sleepiness during the day. Continue treatment

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 Avanza SolTab and consult with
your doctor for a blood test.
In rare cases mirtazapine can cause disturbances in the production of blood cells
(bone marrow depression). Some people become less resistant to infection because Avanza
SolTab can cause a temporary shortage of white blood cells (granulocytopenia). In
rare cases Avanza SolTab 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 Avanza SolTab, 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.
