Warnings and precautions

Consult your doctor or pharmacist before starting to take this medicine.

Tell your doctor before taking Mirtazapine Normon:

If you have ever suffered from severe skin rash or peeling of the skin, blisters or sores in the mouth after taking mirtazapine.

Children and adolescents

Mirtazapine should not normally be used in the treatment of children and adolescents under 18 years of age because it has not been shown to be effective. At the same time, you should know that in patients under 18 years of age there is an increased risk of adverse effects such as suicidal attempts, suicidal ideation, and hostility (mainly aggression, confrontational behavior, and irritation) when taking this type of medicine.

However, your doctor may prescribe mirtazapine to patients under 18 years of age when they decide what is best for the patient. If your doctor has prescribed mirtazapine to a patient under 18 years of age and you want to discuss this decision, please go back to your doctor. You should inform your doctor if any of the above symptoms appear or worsen in patients under 18 years of age who are taking mirtazapine. Additionally, the long-term safety effects of mirtazapine on growth, maturity, and development of knowledge and behavior in this age group are not yet known.

It has also been observed that there is a significant increase in weight in this age group when treated with mirtazapine, compared to adults.

Suicidal thoughts and worsening of depression

If you are depressed, you may sometimes have thoughts of harming yourself or of suicide.

This may worsen when you first start taking antidepressants, as these medicines take 2 weeks or sometimes longer to start working.

You may be more likely to think this way if:

  • You have previously had thoughts of suicide or self-harm.
  • You are a young adult. Clinical trial data have shown an increased risk of suicidal behavior in young adults under 25 years of age with psychiatric disorders who are being treated with an antidepressant.
  • If you have thoughts of self-harm or suicide at any time, contact your doctor or go to a hospital immediately.

It may be helpful to tell a relative or close friendthat you are depressed and ask them to read this leaflet. You can ask them to tell you if they think your depression is getting worse, or if they are worried about changes in your behavior.

Also, be especially careful with mirtazapine:

  • If you have or have ever had any of the following conditions:
  • Tell your doctor about these situations before taking mirtazapine, if you have not already done so.
  • Seizures(epilepsy). If seizures occur 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.

  • Diabetes(you may need to adjust your insulin or other antidiabetic medication dose).

  • If signs of infection appear, such as unexplained high fever, sore throat, and mouth ulcers.
  • Stop taking mirtazapine and contact your doctor immediately for a blood test.

In rare cases, these symptoms can be signs of changes in blood cell production in the bone marrow. Although rare, these symptoms usually appear 4-6 weeks after treatment.

  • If you are an elderly person. You may be more sensitive to the adverse effects of antidepressant medicines.
  • Severe skin reactions have been reported with the use of mirtazapine, such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS). Stop using it and seek medical attention immediately if you notice any of the symptoms described in section 4 related to these severe skin reactions.

If you have ever suffered from severe skin reactions, do not restart treatment with mirtazapine.
