What Mirtazapine is and what it is used for

Mirtazapine is one of a group of medicines called antidepressants.

Mirtazapine is used to treat depressive illness.

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.


• 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

Please also tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Tell your doctor or pharmacist if you are taking (or plan to take) any of the medicines in the following list.

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.

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 tablets contain lactose. If you have been told by your doctor that you have an intolerance for some sugars, contact your doctor before taking this medicinal product.

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 15mg or 30mg every day. Your doctor may advise you to increase your dose after a few days to the amount that is best for you (between 15mg and 45mg 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 your tablets orally.

Swallow your prescribed dose of Mirtazapine without chewing, with some water.

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 have 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.
