1. WHAT IS MIRTAZAPINE AND WHAT IT IS USED FOR
Mirtazapine is one of a group of medicines called antidepressants.
Mirtazapine is used to treat depressive illness.
2. BEFORE YOU TAKE MIRTAZAPINE
Do not take Mirtazapine





if you are allergic (hypersensitive) to mirtazapine or any of the other ingredients of Mirtazapine. If so, you must talk to
your doctor as soon as you can before taking Mirtazapine.
if you are taking or have recently taken (within the last two weeks) medicines called monoamine oxidase inhibitors
(MAO-Is).

Take special care with Mirtazapine
Use in children and adolescents under 18 years of age
Mirtazapine should normally not be used for children and adolescents under 18 years. Also, you should know that patients
under 18 have an increased risk of side-effects such as suicide attempt, suicidal thoughts and hostility (predominantly
aggression, oppositional behaviour and anger) when they take this class of medicines. Despite this, your doctor may prescribe
Mirtazapine for patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed
Mirtazapine for a patient under 18 and you want to discuss this, please go back to your doctor. You should inform your doctor
if any of the symptoms listed above develop or worsen when patients under 18 are taking Mirtazapine. Also, the long-term
safety effects concerning growth, maturation and cognitive and behavioural development of Mirtazapine in this age group
have not yet been demonstrated.
Thoughts of suicide and worsening of your depression
If you are depressed you can sometimes have thoughts of harming or killing yourself. These may be increased when first
starting antidepressants, since these medicines all take time to work, usually about two weeks but sometimes longer.
You may be more likely to think like this:
• if you have previously had thoughts about killing or harming yourself.
• if you are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in adults aged
less than 25 years with psychiatric conditions who were treated with an antidepressant.
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away.
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.
Also take special care with Mirtazapine
• if you have, or have ever had one of the following conditions.
Tell your doctor about these conditions before taking Mirtazapine, if not done previously
- seizures (epilepsy). If you develop seizures or your seizures become more frequent, stop taking Mirtazapine and
contact your doctor immediately;
- liver disease, including jaundice. If jaundice occurs, stop taking Mirtazapine and contact your doctor immediately;
- kidney disease;
- heart disease, or low blood pressure;
- schizophrenia. If psychotic symptoms, such as paranoid thoughts become more frequent or severe, contact your
doctor straight away;
- manic depression (alternating periods of feeling elated/overactivity and depressed mood). If you start feeling elated
or over-excited, stop taking Mirtazapine and contact your doctor immediately;
- diabetes (you may need to adjust your dose of insulin or other antidiabetic medicines);
- eye disease, such as increased pressure in the eye (glaucoma);
- difficulty in passing water (urinating), which might be caused by an enlarged prostate.
• if you develop signs of infection such as inexplicable high fever, sore throat and mouth ulcers.
Stop taking Mirtazapine and consult your doctor immediately for a blood test.
In rare cases these symptoms can be signs of disturbances in blood cell production in the bone marrow. While rare, these
symptoms most commonly appear after 4-6 weeks of treatment.
• if you are an elderly person. You could be more sensitive to the side-effects of antidepressants.
Taking other medicines
Tell your doctor or pharmacist if you are taking (or plan to take) any of the medicines in the following list.
Please also tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines
obtained without a prescription.
Do not take Mirtazapine in combination with:
• monoamine oxidase inhibitors (MAO inhibitors). Also, do not take Mirtazapine during the two weeks after you have
stopped taking MAO inhibitors. If you stop taking Mirtazapine, do not take MAO inhibitors during the next two weeks
either. Examples of MAO inhibitors are moclobemide, tranylcypromine (both are antidepressants) and selegiline (used for
Parkinson’s disease).
Take care when taking Mirtazapine in combination with:
• antidepressants such as SSRIs, venlafaxine and L-tryptophan or triptans (used to treat migraine), tramadol
(a pain-killer), linezolid (an antibiotic), lithium (used to treat some psychiatric conditions) and St. Johns Wort –
Hypericum perforatum preparations (a herbal remedy for depression). In very rare cases Mirtazapine alone or the
combination of Mirtazapine with these medicines, can lead to a so-called serotonin syndrome. Some of the symptoms
of this syndrome are: inexplicable fever, sweating, increased heart rate, diarrhoea, (uncontrollable) muscle contractions,
shivering, overactive reflexes, restlessness, mood changes and unconsciousness. If you get a combination of these symptoms,
talk to your doctor immediately.
• the antidepressant nefazodone. It can increase the amount of Mirtazapine in your blood. Inform your doctor if you are
using this medicine. It might be needed to lower the dose of Mirtazapine, or when use of nefazodone is stopped, to increase
the dose of Mirtazapine again.
• medicines for anxiety or insomnia such as benzodiazepines;
• medicines for schizophrenia such as olanzapine;
• medicines for allergies such as cetirizine;
• medicines for severe pain such as morphine.
In combination with these medicines Mirtazapine can increase the drowsiness caused by these medicines.
• medicines for infections; medicines for bacterial infections (such as erythromycin, medicines for fungal infections (such
as ketoconazole) and medicines for HIV/AIDS (such as HIVprotease inhibitors).
In combination with Mirtazapine these medicines can increase the amount of Mirtazapine in your blood. Inform your doctor
if you are using these medicines. It might be needed to lower the dose of Mirtazapine, or when these medicines are stopped,
to increase the dose of Mirtazapine again.
• medicines for epilepsy such as carbamazepine and phenytoin;
• medicines for tuberculosis such as rifampicin.
In combination with Mirtazapine these medicines can reduce the amount of Mirtazapine in your blood. Inform your doctor
if you are using these medicines. It might be needed to increase the dose of Mirtazapine, or when these medicines are
stopped to lower the dose of Mirtazapine again.
• medicines to prevent blood clotting such as warfarin.
Mirtazapine can increase the effects of warfarin on the blood. Inform your doctor if you are using this medicine. In case of
combination it is advised that a doctor monitors your blood carefully.
Taking Mirtazapine with food and drink
You may get drowsy if you drink alcohol while you are taking Mirtazapine.
You are advised not to drink any alcohol.
You can take Mirtazapine with or without food.
Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking any medicine.
Limited experience with Mirtazapine administration to pregnant women does not indicate an increased risk. However, caution
should be exercised when used during pregnancy.
If you are taking Mirtazapine and you become pregnant or you plan to get pregnant, ask your doctor whether you may
continue taking Mirtazapine. If you use Mirtazapine until, or shortly before birth, your baby should be supervised for possible
adverse effects.
Make sure your midwife and/or doctor knows you are on Mirtazapine. When taken during pregnancy, similar drugs (SSRIs) may
increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the newborn (PPHN), making the
baby breathe faster and appear bluish. These symptoms usually begin during the first 24 hours after the baby is born. If this
happens to your baby you should contact your midwife and/or doctor immediately.
Ask your doctor whether you can breast-feed, while taking Mirtazapine.
Driving and using machines
Mirtazapine can affect your concentration or alertness. Make sure these abilities are not affected before you drive or operate
machinery.
Important information about some of the ingredients of Mirtazapine
Mirtazapine contains lactose and sorbitol. If you have been told by your doctor that you have an intolerance to some
sugars, contact your doctor before taking this medicinal product.
Mirtazapine contains aspartame, a source of phenylalanine. This may be harmful for people with phenylketonuria.
3. HOW TO TAKE MIRTAZAPINE
Always take Mirtazapine exactly as your doctor or pharmacist tells you to. You should check with your doctor or pharmacist if
you are not sure.
How much to take
The usual starting dose is 15 or 30 mg every day. Your doctor may advise you to increase your dose after a few days to the
amount that is best for you (between 15 and 45 mg per day). The dose is usually the same for all ages. However, if you are an
elderly person or if you have renal or liver disease, your doctor may adapt the dose.
When to take Mirtazapine
Take Mirtazapine at the same time each day. It is best to take Mirtazapine as a single dose before you go to bed. However
your doctor may suggest you to split your dose of Mirtazapine – once in the morning and once at night-time before you go to
bed. The higher dose should be taken before you go to bed.

Take the orodispersible tablet as follows
Take your tablets orally.
Mirtazapine are fragile. They must not be pushed through the packaging as this would damage them. To take a tablet out
of the packaging:
1. Hold the blister at the edges and separate one blister cell from the rest of the blister by gently tearing along the
perforations around it.
2. Pull up the marked edge of the foil and peel foil off completely.
3. Tip the tablet out onto your hand.
4. Put the tablet on the tongue as soon as it is removed from the packaging.

When placed on the tongue, the tablet disintegrates rapidly. The disintegrated tablet can be swallowed with or without water.
Your mouth should be empty before placing the tablet on the tongue.
When can you expect to start feeling better
Usually Mirtazapine will start working after 1 to 2 weeks and after 2 to 4 weeks you may start to feel better.
It is important that, during the first few weeks of the treatment, you talk with your doctor about the effects of Mirtazapine:
2 to 4 weeks after you have started taking Mirtazapine, talk to your doctor about how this medicine has affected you.
If you still don’t feel better, your doctor may prescribe a higher dose. In that case, talk to your doctor again after another
2 to 4 weeks.
Usually you will need to take Mirtazapine until your symptoms of depression have disappeared for 4 to 6 months.
If you take more Mirtazapine than you should
If you or someone else has taken too much Mirtazapine, call a doctor straight away.
The most likely signs of an overdose of Mirtazapine (without other medicines or alcohol) are drowsiness, disorientation
and increased heart rate.
If you forget to take Mirtazapine
If you are supposed to take your dose once a day
• If you have forgotten to take your dose of Mirtazapine, do not take the missed dose. Just skip it.
Take your next dose at the normal time.
If you are supposed to take your dose twice a day
• if you have forgotten to take your morning dose, simply take it together with your evening dose.
• if you have forgotten to take your evening dose, do not take it with the next morning dose; just skip it and continue with
your normal morning and evening doses.
• if you have forgotten to take both doses, do not attempt to make up for the missed doses. Skip both doses and continue
the next day with your normal morning and evening doses.
If you stop taking Mirtazapine
→ Only stop taking Mirtazapine in consultation with your doctor.
If you stop too early, your depression might come back. Once you are feeling better, talk to your doctor. Your doctor will decide
when treatment can be stopped.
Do not suddenly stop taking Mirtazapine, even when your depression has lifted. If you suddenly stop taking Mirtazapine you
may feel sick, dizzy, agitated or anxious, and have headaches. These symptoms can be avoided by stopping gradually. Your
doctor will tell you how to decrease the dose gradually.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
