Warnings and cautions

Talk to your doctor, pharmacist, or nurse before taking Mirtazapine Alternova.

Children and young people

Mirtazapine Alternova should not normally be used in the treatment of children and adolescents under 18 years of age as no effect has 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, Mirtazapine Alternova can be prescribed to patients under 18 years of age, if the doctor deems it appropriate. If you are under 18 years of age and want to discuss why you received this medicine, consult your doctor again.

You should also tell your doctor if you notice any of the above symptoms or if they get worse. The long-term effects on growth, maturity, and cognitive and behavioral development have not yet been established for children and adolescents under 18 years of age. In addition, significant weight gain has been observed more frequently in this age group when receiving Mirtazapine Alternova 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, take special care with Mirtazapine Alternova

  • if you have or have had:
    • cramps ( epilepsy ). If you get cramps or if your cramps come more often, stop taking Mirtazapine Alternova and contact your doctor immediately.
    • liver disease, including jaundice. If you get jaundice, stop taking Mirtazapine Alternova and contact your doctor immediately.
    • kidney disease
    • heart disease (eg conduction disorders, angina, heart attack). Especially if you are taking certain medicines that may affect your heart rhythm with Mirtazapine Alternova.
    • low blood pressure
    • difficulty urinating (eg due to enlarged prostate )
    • eye disease, such as increased pressure in the eye ( glaucoma )
    • diabetes (you may need to adjust dose one on insulin or other antidiabetic drugs)
    • schizophrenia. If psychotic symptoms such as paranoid thoughts occur more often or become more severe, contact your doctor immediately.
    • manic depression (alternating periods of elation and depression). If you start to feel elated or overexcited, stop taking Mirtazapine Alternova and contact your doctor immediately.
    • akathisia / psychomotor restlessness (inability to sit still)
  • If you get signs of infection such as unexplained high fever, sore throat and sore mouth, stop taking Mirtazapine Alternova and contact your doctor immediately for a blood test.
    In rare cases, these symptoms may be a sign of a disturbance 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 older person. You may be more sensitive to the side effects of antidepressants.

A syndrome called serotonergic syndrome can occur in rare cases if mirtazapine is used in combination with other drugs that increase the release of serotonin. The main symptoms of a serotonergic syndrome are fever (above 38 ° C) and muscle twitching but can also include confusion, irritability, and extreme agitation that turns into delirium (a mental disorder with symptoms such as attention deficit, motor problems, and delusions) and coma. Contact your doctor if such symptoms occur. You may need to stop taking the medicine and receive treatment.

Although mirtazapine is not considered addictive, abrupt discontinuation of treatment may lead to withdrawal symptoms such as nausea, headache, dizziness, agitation, anxiety, and malaise. Contact your doctor for advice on how to reduce the treatment gradually.

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 Alternova again.
