Children and adolescents

Mirtagen should not be used in children and adolescents under 18 years of age, as its efficacy has not been established.
It should also be noted that in patients under 18 years of age treated with this type of medicine, there is an increased risk of adverse reactions such as suicidal attempts, suicidal thoughts, and hostility (especially aggression, rebelliousness, and anger).
However, your doctor may prescribe Mirtagen to patients under 18 years of age if he/she considers it to be in their best interest.
If your doctor has prescribed Mirtagen to a patient under 18 years of age and the patient wishes to discuss this, they should consult their doctor again.
If symptoms such as those mentioned above worsen in patients under 18 years of age taking Mirtagen, the treating doctor should be informed.
Additionally, the long-term effects of Mirtagen on safety, including effects on growth, maturation, and cognitive and behavioral development, have not been established in this age group.
Furthermore, significant weight gain has been observed more frequently in patients treated with mirtazapine in this age group compared to adults.

Suicidal thoughts and worsening of depression

Patients with depression may sometimes have thoughts of self-harm or suicidal thoughts.
These thoughts may worsen when antidepressant medicines are first taken, as these medicines take time to work, usually about 2 weeks, and sometimes longer.
The patient may be particularly at risk:

• If the patient has had thoughts of self-harm or suicide before.
• If the patient is a young adult. Information from clinical trials has shown an increased risk of suicidal behavior in adults under 25 years of age with mental disorders treated with antidepressants.
  In the event of suicidal thoughts or suicidal attempts, contact your doctor or go to the hospital immediately.

Talking to someone close to you or a friend may be helpful.The patient may inform these people about their depression and ask them to read this leaflet so that they can tell the patient if they notice a worsening of their condition or unusual changes in behavior.

When combined with Mirtagen, these medicines may increase the level of mirtazapine in the blood. Tell your doctor if you are taking these medicines. It may be necessary to reduce the dose of Mirtagen, and after stopping treatment with these medicines, the dose of Mirtagen may need to be increased.

Medicines that decrease the level of mirtazapine in the blood:

• carbamazepine and phenytoin, medicines used to treat epilepsy; rifampicin, a medicine used to treat tuberculosis. When combined with Mirtagen, these medicines may decrease the level of Mirtagen in the blood. Tell your doctor if you are taking these medicines.

4. Possible side effects

Like all medicines, Mirtagen can cause side effects, although not everybody gets them.

If you experience any of the following symptoms, stop taking Mirtagen and contact your doctor or go to the emergency room immediately:

Rare(may affect up to 1 in 1000 people):

• Pancreatitis, causing moderate to severe abdominal pain radiating to the back.

Frequency not known(frequency cannot be estimated from the available data):

• seizures (convulsions)
• yellowing of the skin or eyes, which may indicate liver function disorders (jaundice)
• a combination of symptoms such as unexplained fever, sweating, increased heart rate, diarrhea, (uncontrolled) muscle spasms, chills, increased reflexes, anxiety, mood changes, and loss of consciousness. In very rare cases, these may be symptoms of serotonin syndrome
• thoughts of self-harm or suicide or suicide attempts
• red skin lesions on the torso in the form of target-like spots or round spots, often with blisters in the center; skin peeling; ulcers of the mucous membranes of the mouth, throat, nose, eyes, and genitals. This type of severe skin rash may be preceded by fever and flu-like symptoms (Stevens-Johnson syndrome, toxic epidermal necrolysis)
• widespread rash, high fever, and swollen lymph nodes (DRESS syndrome or drug hypersensitivity syndrome)
• infection symptoms such as sudden high fever, sore throat, and mouth ulcers (agranulocytosis). Mirtazapine may cause blood disorders (bone marrow suppression). Some people become less resistant to infections because mirtazapine can cause a temporary decrease in the number of white blood cells (granulocytopenia). In rare cases, mirtazapine may also cause a decrease in the number of red and white blood cells, as well as platelets (aplastic anemia), a decrease in the number of platelets (thrombocytopenia), or an increase in the number of white blood cells (eosinophilia),
• muscle tissue breakdown, causing muscle pain, tenderness, stiffness, and (or) weakness, as well as dark urine (rhabdomyolysis)
• difficulty urinating or emptying the bladder
• lower than normal sodium levels in the blood, which may cause feelings of weakness and disorientation with muscle pain. This may be due to the improper secretion of antidiuretic hormone, which causes water retention in the body and dilution of the blood, reducing the amount of sodium.
