Mirtin – Mirtazapine uses, dose and side effects


15 mg, 30 mg, 45 mg orodispersible tablets

What Mirtin is and what it is used for

Mirtin belongs to a group of medicines called antidepressants .

Mirtin is used to treat depression in adults.

It will take 1-2 weeks before Mirtin starts working. After 2-4 weeks, you can start to feel better. Contact your doctor if you do not feel better or if you feel worse after 2-4 weeks. For more information, see section 3 under the heading “When you can expect to start feeling better”.

Mirtazapine contained in Mirtin may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist or other healthcare professional if you have any further questions and always follow their instructions.

What you need to know before you use Mirtin

Do not use Mirtin

  • if you are allergic to mirtazapine or any of the other ingredients of this medicine (listed in section 6). If so, talk to your doctor as soon as possible before taking Mirtin.
  • if you are taking or have recently taken (within the last two weeks) medicines called monoamine oxidase inhibitors ( MAOIs ).

Warnings and cautions

Talk to your doctor or pharmacist before taking Mirtin:

  • if you have ever had a severe rash or flaky skin, blisters and / or sores in your mouth after taking mirtazapine or other medicines.

Children and young people

Mirtin should not normally be used in the treatment of children and adolescents under 18 years of age as an effect has not been demonstrated. The risk of side effects such as suicide attempts, suicidal thoughts and hostility (mainly aggression, defiance and anger) is greater in patients under 18 years of age, when taking drugs of this type. Despite this, Mirtin can be prescribed by a doctor to patients under the age of 18, if the doctor deems it appropriate.

If your doctor has prescribed Mirtin to someone under the age of 18 and you want to discuss this, you should see your doctor again. You should also tell your doctor if you notice any of the above symptoms or if they get worse when patients under 18 years of age use Mirtin. The long-term effects of Mirtin on growth, maturation and cognitive and behavioral development have not yet been established in children and adolescents below 18 years of age. In addition, significant weight gain has been observed more frequently in this age group when receiving mirtazapine compared to adults.

If you start to feel worse and have thoughts of harming yourself

You who are depressed can sometimes have thoughts of harming yourself or committing suicide. These symptoms may worsen when you start taking antidepressants, as it takes time for a drug of this type to take effect, usually about 2 weeks, sometimes longer.

These thoughts may be common:

  • if you have previously had thoughts of harming yourself or committing suicide,
  • if you are younger than 25 years. Studies have shown that young adults (younger than 25 years) with mental illness who are treated with antidepressant drugs have an increased risk of suicidal thoughts and thoughts of harming themselves.

→ Contact a doctor as soon as possible or go to the nearest hospital if you have thoughts of injuring yourself or committing suicide. It can be helpful to tell a relative or close friend that you are depressed. Feel free to ask them to read this leaflet. You can also ask them to tell you if they think you are feeling worse or if they think your behavior is changing.

Also, be especially careful with Mirtin

• if you have or have had any of the following conditions.

→ Tell your doctor about these conditions before starting Mirtin if you have not done so before.

  • cramps ( epilepsy ). If you get cramps or if your cramps come more often, stop taking Mirtin and contact your doctor immediately
  • liver disease , including jaundice. If you get jaundice, stop taking Mirtin and contact your doctor immediately
  • kidney disease .
  • heart diseaseor low blood pressure
  • schizophrenia If psychotic symptoms such as paranoid thoughts occur more often or become more severe, contact your doctor immediately
  • manic depression(alternating periods of feeling elated / overactive and depressed). If you start to feel excited or overexcited, stop taking Mirtin and contact your doctor immediately.
  • diabetes(you may need to adjust your dose of insulin or other diabetes medicines)
  • eye disease , such as increased pressure in the eye ( glaucoma )
  • difficultyurinating (urinating), which may be due to an enlarged prostate
  • certain types of heart problems that can change your heart rhythm, a recent heart attack, heart failure , or taking certain medications that can affect your heart rhythm.

• if you get signs of infection such as unexplained high fever, sore throat and sore mouth.

→ Stop taking Mirtin and contact your doctor immediately for a blood test. In rare cases, this may be a sign of a disorder in the production of blood cells in the bone marrow . It is rare, but if they do occur, it is generally after 4-6 weeks of treatment

• if you are an elderly person. You may be more sensitive to the side effects of antidepressants.

• severe skin reactions such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported with mirtazapine. Stop using the medicine and seek medical attention immediately if you get any of the symptoms described in section 4 in connection with these severe skin reactions.

• if you have ever had a severe skin reaction, you should never be treated with mirtazapine again.

Do not take Mirtin in combination with:

  • monoamine oxidase inhibitors( MAOIs ). Also, do not take Mirtin for two weeks after stopping MAOIs . If you stop taking Mirtin, do not take MAO inhibitors during the first two weeks. Examples of MAO inhibitors are moclobemide, tranylcypromine (both are antidepressants) and selegiline (used in Parkinson’s disease )

  • schizophrenia drugs such as olanzapine;
  • Allergy medicines such as cetirizine ;
  • medicines for severe pain such as morphine If you combine these medicines with Mirtin, the drowsiness you get from these medicines may increase.

Pregnancy, breastfeeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

If you are using Mirtin until or just before delivery, your baby should be checked for any side effects .

When similar drugs ( SSRIs ) are used during pregnancy, the risk of a serious condition called persistent pulmonary hypertension in the newborn (PPHN) may increase. This condition causes the baby to breathe faster and look blue. The symptoms usually appear within 24 hours of the baby being born. If this affects your baby, contact a midwife or doctor immediately.

Driving and using machines

Mirtin may affect your concentration or reactivity. Make sure your ability has not been affected before driving or using tools or machines. If your doctor has prescribed Mirtin to a patient under the age of 18, make sure that their ability to concentrate and react is not affected before the person enters traffic (eg by bicycle).

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened vigilance. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and / or side effects . Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.
