What is in this leaflet
This leaflet answers some common questions about Axit.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking Axit against the benefits expected for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
What Axit is used for
Axit 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.
Axit 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 Axit has been prescribed for you. Axit is available only with a doctor's prescription.
Axit is not addictive.
Before you take Axit
When you must not take it
Do not take Axit:
- 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 Axit 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. If you stop taking Axit, do not take MAOI during the next two weeks either. Taking Axit with an MAOI may cause a serious reaction with a sudden increase in body temperature, extremely high blood pressure and severe convulsions.
Examples of MAOIs are phenelzine, tranylcypromine and selegiline.
Ask your doctor or pharmacist if you are not sure if you are taking, or if you have been taking a MAOI medicine.
Do not take Axit if you have galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption, as this medicine contains lactose.
Do not take Axit if the expiry date (EXP) printed on the pack has passed. If you take this medicine after the expiry date, it may not work as well.
Do not take Axit if the packaging shows signs of tampering or the tablets do not look quite right.
If you are not sure whether you should start taking this medicine, talk to your doctor.
Before you start to take it
Do not give Axit to a child or adolescent. The safety of Axit in patients under 18 years has not been established.

How to take Axit
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist.
How much to take
Your doctor will tell you how much Axit to take each day. Take exactly the amount your doctor tells you. The usual starting dose is 15 mg per day. Your doctor may slowly increase this dose depending on how you respond to this medicine. The effective dose for most people is usually between 30 and 45 mg daily.
Your doctor may have prescribed a different dose.
How to take it
Swallow the tablets with a glass of water.
Do not crush or chew the tablets.
Axit 15 and Axit 30 tablets can be divided in half along the breakline, if advised by your doctor or pharmacist.
Axit can be taken with or without food.
When to take it
Take your medicine 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, Axit 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 long to take it for
Keep taking Axit 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 don't 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 longer to feel the full benefit of the medicine.
Even when you feel well, you will usually have to take Axit 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 Axit before you go to bed, do not take the missed dose the 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 Axit. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much Axit, you may feel drowsy, dizzy, confused and agitated.
You may also have changes to your heart rhythm (fast, irregular heartbeat) and/or fainting which could be symptoms of a life-threatening condition known as Torsade de Pointes.
While you are taking Axit
Things you must do
Tell your doctor immediately if you develop fever, chills, sore throat or mouth ulcers or other signs of frequent infections. Stop taking Axit and consult with your doctor for a blood test.
In rare cases Axit can cause disturbances in the production of blood cells (bone marrow depression). Some people become less resistant to infection because Axit can cause a temporary shortage of white blood cells (granulocytopenia). In rare cases Axit can also cause a shortage of red and white blood cells, as well as blood platelets (aplastic anaemia), a shortage of blood platelets (thrombocytopenia) or an increase in the number of white blood cells (eosinophilia). 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.
Information from clinical trials have shown an increased risk of suicidal behaviour in young adults aged less than 25 years with psychiatric conditions who were treated with an antidepressant.
If you or someone you know is showing warning signs of suicide-related behaviour while taking Axit, 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.
You may find it helpful to tell a relative or close friend that you are depressed and ask them to read this leaflet. You might ask them to tell you if they think your depression is getting worse, or if they are worried about changes in your behaviour.
Tell all the doctors, dentists and pharmacists who are treating you that you are taking Axit.
Tell your doctor if you become pregnant while taking Axit. Do not stop taking your tablets until you have spoken to your doctor.
If you use Axit until, or shortly before birth, your baby should be supervised for possible adverse effects.
Ask your doctor whether you can breastfeed, while taking Axit.
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. Your doctor may want to take some blood tests and check your heart and blood pressure from time to time. This helps prevent unwanted side effects.
Before starting any new medicine, tell your doctor or pharmacist that you are taking Axit.
Things you must not do
Do not drive or operate machinery until you know how Axit affects you. Axit 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 Axit, or lower the dose, without first checking with your doctor.
Do not let yourself run out of medicine over weekends or on holidays.
Do not stop taking Axit, even if you feel better, unless advised by your doctor. Suddenly stopping Axit may cause nausea (feeling sick), headache, dizziness, anxiety, agitation.
Your doctor may want you to gradually reduce the amount of Axit you are taking before stopping completely.
Do not use Axit to treat any other conditions unless your doctor tells you to.
Do not give Axit 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
You are advised not to drink any alcohol while taking Axit. Combining Axit and alcohol can make you more sleepy and less alert. Your doctor may suggest you avoid alcohol while being treated with this medicine.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Axit. Axit helps most people with depression, but it may have unwanted side effects in some people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
- lethargy, drowsiness or sleepiness
- increase in appetite and weight gain
- dry mouth
- nausea, vomiting
- dizziness or faintness when getting up quickly from a lying or sitting position (low blood pressure)

- shaking or tremors
- sudden muscle contractions (myoclonus)
- attack of excessive excitability (mania)
- changes to your heart rhythm
- yellow colouring of eyes or skin; this may suggest disturbance in liver function

- a combination of symptoms such as fever, sweating, increased heart rate, diarrhoea, (uncontrollable) muscle contractions, shivering, overactive reflexes, restlessness, mood changes, unconsciousness and increased salivation (serotonin syndrome)
The above list includes rare but very serious side effects. You may need urgent medical attention or hospitalisation.
Tell your doctor if you notice anything else that is making you feel unwell.
Other side effects not listed above may also occur in some patients.
Ask your doctor or pharmacist if you don't understand anything in this list.
