What MIRTAZAPINE SANDOZ® ODT is used for

Depression is longer lasting or more severe than "low moods" everyone has from time to time due to the stress of everyday life.

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.

This medicine is only available with a doctor's prescription.

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 MIRTAZAPINE SANDOZ® 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 SANDOZ® 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 MIRTAZAPINE SANDOZ® ODT 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, MIRTAZAPINE SANDOZ® ODT 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
MIRTAZAPINE SANDOZ® 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 Figure 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 Figure 2).
- Carefully peel off the lidding foil, starting in the corner indicated by the arrow (see Figure 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 Figure 4 & 5)

How long to take it
Keep taking MIRTAZAPINE SANDOZ® 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 MIRTAZAPINE SANDOZ® ODT for 4 to 6 months or even longer to make sure the benefits will last.

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.

All mentions of suicide or violence must be taken seriously.
