What Mirtanza ODT is used for
Mirtanza ODT 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 available only with a doctor’s prescription.
Mirtanza ODT is not addictive.
Before You Take Mirtanza ODT
When you must not take it

How to take Mirtanza ODT
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 Mirtanza ODT 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 MIRTAZAPINE ODT. 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 Mirtanza 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, Mirtanza 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
Mirtanza ODT 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 (see fig. 1)
- Each blister contains ten tablet pockets, which are separated by perforations (dotted lines). Bend the strip several times along the dotted lines, and then tear off one tablet pocket (see fig. 2).
- Carefully peel off the lidding foil, starting in the corner indicated by the arrow (see fig. 3).
- 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 (see fig. 4 & 5).
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 Mirtanza ODT 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 Mirtanza ODT 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 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 Mirtanza ODT. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too many Mirtanza ODT tablets, you may feel drowsy, dizzy, confused, agitated, have increased heart rate or lose consciousness.
While you are taking Mirtanza ODT
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 Mirtanza ODT 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 Mirtanza ODT, 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.
