HOW TO TAKE MIRTAZAPINE SANDOZ
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions, ask your doctor or pharmacist for help.
How much to take
Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take.
The usual starting dose is 15 mg per day. Your doctor may slowly increase this dose depending on how you respond to Mirtazapine Sandoz. The effective dose for most people is usually between 30 mg and 45 mg per day.
Your doctor may have prescribed a different dose.
Follow the instructions they give you. If you take the wrong dose, Mirtazapine Sandoz may not work as well and your problem may not improve.
How to take it
Swallow the tablets whole with a full glass of water.
If you need to break Mirtazapine Sandoz 30 mg tablets in half, hold the tablet with both hands and snap along the break line.
When to take Mirtazapine Sandoz
Take your medicine at about the same time each day, preferably as a single night-time dose before going to bed. Taking it at the same time each day will help you remember when to take it.
If recommended by your doctor, this medicine may be taken in sub-doses equally divided over the day (for example, once in the morning and once at night-time before going to bed).
How long to take Mirtazapine Sandoz
Continue taking your medicine for as long as your doctor tells you.
For depression, the length of treatment depends 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 symptoms may improve in 1 to 2 weeks, but it can take up to 2 to 4 weeks to feel the full benefit of the medicine.
It is important to keep taking your medicine even if you feel well, usually for about 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 the next morning.
This medicine may cause drowsiness or sleepiness during the day.
Continue treatment in the evening with your usual dose, and continue to take it as you would normally.
Twice daily dosing:
- If you forget your morning dose:
take your morning dose together with your evening dose.
- If you forget your evening dose:
do not take it with the next morning dose. Continue treatment with your usual evening dose, and continue to take it as you would normally.
- If you forget both doses:
do not try to make up for missed doses. Continue treatment with your usual morning and evening dose the next day.
If you are not sure what to do, ask your doctor or pharmacist.
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 that you or anyone else may have taken too much Mirtazapine Sandoz. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention. If you take too many tablets, you may feel drowsy, dizzy, confused, agitated, have increased heart rate or lose consciousness.
WHILE YOU ARE TAKING MIRTAZAPINE SANDOZ
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Mirtazapine Sandoz.

If you become pregnant while taking this medicine, tell your doctor immediately.
Do not stop taking your tablets until you have spoken to your doctor.
If you develop fever, chills, sore throat or mouth ulcers or other signs of frequent infections, tell your doctor immediately.
In rare cases, mirtazapine 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.
If you have any suicidal thoughts or other mental/mood changes, tell your doctor immediately or go to the nearest hospital for treatment. Occasionally, the symptoms of depression or other psychiatric conditions may include thoughts of harming yourself or committing suicide. Until the full effects of your medicine become apparent, these symptoms may increase in the first few weeks of treatment.
If you or someone you know is showing signs of suicide-related behaviour while taking Mirtazapine Sandoz, contact your doctor or a mental health professional immediately 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.
Any mention of self-harm, violence or suicide must be taken seriously.
Keep all of your doctor's appointments so that your progress can be checked. Your doctor may do some blood tests from time to time. This helps to prevent unwanted side effects.
Tell your doctor if you feel the tablets are not helping your condition.
Tell your doctor if you have not taken your medicine exactly as prescribed. Otherwise your doctor may think that it was not effective and change your treatment unnecessarily.

If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.

Your doctor may want you to gradually reduce the amount you are taking before stopping completely. This may help reduce the possibility of withdrawal symptoms such as nausea, headache, dizziness, anxiety and agitation.
