What this medicine is used for

The name of your medicine is Terry White Chemists Mirtazapine. It contains the active ingredient mirtazapine.
It is used to treat and prevent the reoccurrence of depression.
Depression is longer lasting or more severe than the “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.
Mirtazapine corrects this chemical imbalance and may help relieve the symptoms of depression.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor’s prescription.
There is no evidence that this medicine is addictive.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take this medicine

Follow carefully all directions given to you by your doctor or pharmacist.
Their instructions may be different to the information in this leaflet.

How much to take

This will depend on your condition and whether you are taking any other medicines.
The usual starting dose is 15 mg per day. Your doctor may slowly increase your dose depending on how you respond to mirtazapine.
The effective dose for most people is usually between 30 mg and 45 mg per day.
Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Swallow the tablets whole with a full glass of water.

When to take it

Take this medicine at the same time each day, preferably as a single night-time dose before going to bed.
If recommended by your doctor, your dose may be taken in sub-doses equally divided over the day (e.g. once in the morning and once at night-time before going to bed).
It does not matter if you take it before, with or after food.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.
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 1-2 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 your medicine for 4-6 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 your dose before going to bed, do not take the missed dose the next morning, because it may cause drowsiness or sleepiness during the day. Wait until the next evening before taking your normal dose.
Do not take a double dose to make up for the missed dose.
Twice-Daily Dosing:
If you forget your morning dose, simply take it together with your evening dose.
If you forget your evening dose, do not take it with the next morning dose.
Skip the missed dose and continue treatment with your normal morning and evening doses.
If you have forgotten both doses, you should not make up for the missed doses; the next day, just continue with your normal morning and evening doses.
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 of this medicine. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much mirtazapine you may feel drowsy, dizzy, confused, agitated, have increased heart rate or lose consciousness.

While you are taking this medicine

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this medicine.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.
It may affect other medicines used during surgery.
If you become pregnant or start to breastfeed while taking this medicine, tell your doctor immediately.
If you are about to have any blood tests, tell your doctor that you are taking this medicine.
It may interfere with the results of some tests.
Keep all your doctor’s appointments so that your progress can be checked.
Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects.
Go to your doctor regularly for a check-up.
Tell your doctor immediately if you develop fever, chills, sore throat or mouth ulcers or experience other signs of infections.
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.
Tell your doctor immediately or go to the nearest hospital for treatment if you have any suicidal thoughts or other mental/mood changes.
Young adults aged 18 to 24 are at particularly high risk of having this happen to them.
Occasionally, the symptoms of depression or other psychiatric conditions may include thoughts of harming yourself or committing suicide. Until the full antidepressant effect of the medicine becomes apparent, it is possible that these symptoms may increase in the first few weeks of treatment.
If you or someone you know is demonstrating any of the following warning signs of suicide while taking this medicine, contact your doctor or health professional immediately or go to the nearest hospital for treatment:
thoughts or talk of death or suicide
thoughts or talk of self-harm or harm to others
any recent attempts to self-harm
increase in aggressive behaviour, irritability or agitation.
All mention of suicide or violence must be taken seriously.
If you have diabetes take care to monitor your blood sugar levels. Your diabetes medication may need to be adjusted.
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 this medicine is not helping your condition.

Things you must not do

Do not take this medicine to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor.
Stopping your medicine suddenly may cause nausea, headache, dizziness, anxiety or agitation.
Your doctor may want to gradually reduce the amount of medicine you are taking before stopping completely.

Things to be careful of

Be careful when driving or operating machinery until you know how this medicine affects you.
Mirtazapine may cause drowsiness, sleepiness or dizziness 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.
Be careful when drinking alcohol while taking mirtazapine.
Taking mirtazapine with alcohol can make you sleepier and less alert.
Your doctor may suggest you avoid alcohol while being treated with this medicine.
