6.Contents of the pack and additional information

Lantanon belongs to a group of medications called antidepressants. Lantanon alleviates the depressed mood caused by depression. Depression is an emotional disorder. During depression, changes occur in the brain: brain nerve cells communicate with each other through chemical substances, and in depression, the normal amount of these substances is lower. Antidepressants can correct these deficiencies and restore normal brain function. In general, improvement is experienced within 2-4 weeks of treatment.

Do not takeLantanon

• if you are allergic to the active ingredient (mianserina) or any of the other components of this medication (listed in section 6).
• if you have mania (a state of euphoria and hyperactivity).
• if you have liver disease.
• if you are taking or have taken in the last two weeks monoamine oxidase inhibitors (MAOIs).

Use in children and adolescents under 18 years

Lantanon should not be used normally in the treatment of children and adolescents under 18 years. At the same time, you should know that in patients under 18 years there is a higher risk of adverse effects such as suicide attempts, suicidal thoughts, and hostility (mainly aggression, confrontational behavior, and irritability) when taking this type of medication. Despite this, the doctor who prescribes it may prescribe Lantanon to patients under 18 years when they decide it is the most convenient for the patient. If the doctor who prescribes it has prescribed Lantanon to a patient under 18 years and wants to discuss this decision, please return to your doctor. You should inform your doctor if any of the symptoms listed below progress or experience complications when patients under 18 years are taking Lantanon. At the same time, the long-term effects regarding safety and related to growth, maturity, and cognitive and behavioral development of Lantanon in this age group have not yet been demonstrated.

Suicidal thoughts and worsening of depression

If you are depressed and/or have anxiety disorders, you may sometimes have thoughts of harming yourself or committing suicide. This could worsen when you start taking antidepressants for the first time, as these medications usually take two weeks or more to have a normal effect.

You may be more prone to thinking this way if:

• if you have previously had suicidal thoughts or self-harm thoughts,
• if you are a young adult. Information from clinical trials has shown an increased risk of suicidal behavior in adults under 25 years with psychiatric disorders and being treated with an antidepressant.

If you have thoughts of harming yourself or committing suicide at any time,consult your doctor or go to the hospital immediately.

It may be helpful to tell a close relative or friendthat you are depressed or feel anxious, and ask them to read this leaflet. You can ask them to tell you if they think your depression or anxiety are worsening, or if they are concerned about changes in your behavior.
