What Avanza is used for

Avanza is used in the treatment of depression including relapse prevention.

Depression is longer lasting or more severe than "low moods" everyone has from time to time due to the stress of everyday life. It is thought to be caused by a chemical imbalance in parts of the brain. This affects your whole body and can cause emotional and physical symptoms such as feeling low in spirit, loss of interest in activities, 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.

This medicine corrects this chemical imbalance and may help relieve the symptoms of depression.

Your doctor, however, may prescribe it for another purpose.

Ask your doctor if you have any questions about why it has been prescribed for you. This medicine is only available with a doctor's prescription.

Avanza is not addictive.

Before you take Avanza

When you must not take it

Do not take Avanza:

• if you are allergic to medicines containing mirtazapine
• if you are allergic to any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include skin rash, itching or hives, swelling of the face, lips, mouth, throat or other parts of the body, shortness of breath, wheezing or trouble breathing.

Do not take Avanza if you are taking another medicine for depression called a monoamine oxidase inhibitor (MAOI) or have been taking an MAOI within the last 14 days. Taking Avanza with an MAOI may cause a serious reaction with a sudden increase in body temperature, extremely high blood pressure and severe convulsions.

Examples of this type of medicine include phenelzine, tranylcypromine and selegiline.

Ask your doctor or pharmacist if you are not sure if you are or if you have been taking a MAOI medicine.

Do not take Avanza if the packaging is torn or shows signs of tampering.

Do not take Avanza if the expiry date printed on the pack has passed.

If you are not sure whether you should start taking Avanza, talk to your doctor.

1. you are allergic to any other medicines, foods, dyes or preservatives
2. you are pregnant or plan to become pregnant.
   Like most medicines of this kind, Avanza is not recommended to be used during pregnancy. Your doctor will discuss the risks and benefits of taking Avanza when pregnant.

How to take Avanza

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 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. 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 for help.

When to take it

Take Avanza 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 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

Swallow the tablet(s), without chewing, together with some water or other fluid.

How long to take it

Keep taking Avanza 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 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 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 hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone Australia  13 11 26 or New Zealand 0800 POISON or 0800 764 766) for advice, or go to Accident and Emergency at your nearest hospital if you think you or anyone else may have taken too much Avanza. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

If you take too many Avanza tablets, you may feel drowsy, dizzy, confused, agitated, have increased heart rate or lose consciousness.

While you are taking Avanza

Things you must do

Tell your doctor immediately if you develop fever, chills, sore throat or mouth ulcers or other signs of frequent infections.

In rare cases Avanza can cause a shortage of white blood cells, resulting in lowering body resistance to infection. These symptoms may appear after 2 - 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.

If you or someone you know is showing warning signs of suicide-related behaviour while taking Avanza, 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.

Tell your doctor if you become pregnant while taking this medicine. Do not stop taking your tablets until you have spoken to your doctor.

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 unnecessarily.

Tell your doctor if you feel the tablets are not helping your condition.

Be sure to keep all of your appointments with your doctor so that your progress can be checked. You may need to have blood tests from time to time.

Before starting any new medicine, tell your doctor or pharmacist that you are taking Avanza.

Tell all doctors, dentists and pharmacists who are treating you that you are taking Avanza.

Things you must not do

Do not drive or operate machinery until you know how Avanza affects you. Avanza may cause drowsiness, dizziness or sleepiness in some people and affect alertness and concentration. If any of these occur, do not drive, operate machinery or do anything else that could be dangerous.

Do not suddenly stop taking Avanza, or lower the dose, without first checking with your doctor.

Do not let yourself run out of medicine over the weekend or on holidays.

Do not stop taking Avanza, even if you feel better, unless advised by your doctor. Suddenly stopping Avanza may cause nausea, headache, dizziness, anxiety, agitation.

Your doctor may want to gradually reduce the amount of Avanza you are taking before stopping completely.

Do not use Avanza to treat any other conditions unless your doctor tells you to.

Do not give this medicine to anyone else, even if their symptoms seem similar to yours or if they have the same condition as you.

Things to be careful of

Be careful when drinking alcohol while taking Avanza. Combining Avanza and alcohol can make you more sleepy and less alert. Your doctor may suggest you avoid alcohol while being treated with this medicine.
