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 patients under 18 years of age who take medicines of this type are at increased risk of side effects such as suicidal thoughts, suicidal attempts, and hostility (especially aggression, rebellious behavior, and anger).
However, the doctor may prescribe Mirtagen to patients under 18 years of age if they consider it to be in their best interest.
If the doctor has prescribed Mirtagen to a patient under 18 years of age and the patient wants to discuss this, they should consult their doctor again.
If the patient under 18 years of age who is taking Mirtagen develops or worsens the above-mentioned symptoms, they should inform their treating doctor.
Additionally, the long-term effects of Mirtagen on safety regarding growth, maturation, and cognitive and behavioral development in this age group have not been established.
Furthermore, significant weight gain has been more frequently observed 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.
Such 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 previously had thoughts of self-harm or suicide.
• 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, the patient should immediately contact their doctor or go to the hospital.

Talking to someone close, such as a family member or 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.
Before starting treatment with Mirtagen, the patient should discuss the following conditions with their doctor or pharmacist if they are present or have been present:

• seizures(epilepsy)
• liver disease, including jaundice
• kidney disease
• heart disease or a family history of heart disease, including certain heart rhythm disorders that can cause changes in heart rhythm, recent myocardial infarction, heart failure, or the use of certain medicines that can cause heart rhythm disorders
• low blood pressure
• schizophrenia
• bipolar affective disorder(alternating periods of elevated mood and depression);
• diabetes(may require a change in insulin or other hypoglycemic medication dose);
• eye diseases, such as increased intraocular pressure (glaucoma);
• difficulty urinating, which may be caused by an enlarged prostate.

Elderly patients

Elderly patients are often more sensitive, especially to the side effects of antidepressant medicines.

During treatment

The patient should inform their doctor if they experience symptoms of infection such as high fever, sore throat, mouth ulcers.
In rare cases, these symptoms may be a sign of blood disorders.
Although they are rare, these symptoms usually occur within 4-6 weeks of treatment.

• monoamine oxidase inhibitors (MAOIs)or within two weeks of stopping their use.
  Do not start taking Mirtagen within two weeks of stopping MAOIs.

The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take, including those available without a prescription, and in particular:

• other antidepressant medicines such as SSRIs(e.g., citalopram), venlafaxine, L-tryptophan or triptans(used to treat migraines), tramadol(a pain reliever), linezolid(an antibiotic), lithium salts(used to treat certain psychiatric disorders), methylene blue(used to treat high levels of methemoglobin in the blood), and St. John's Wort (Hypericum perforatum)(herbal preparations used to treat depression).

• medicines used to treat severe pain, such as morphine.
  Mirtagen in combination with these medicines may increase the sedation caused by these medicines.

Medicines that increase the level of mirtazapine in the blood:

• medicines used to treat infections: antibacterial medicines (such as erythromycin), antifungal medicines (such as ketoconazole), medicines used to treat HIV and AIDS (such as HIV protease inhibitors, e.g., ritonavir, nelfinavir); antidepressant medicines(such as nefazodone) and medicines used to treat stomach ulcers (such as cimetidine).
  In combination with Mirtagen, these medicines may increase the level of mirtazapine in the blood.
  The patient should inform their doctor about taking these medicines.
  It may be necessary to reduce the dose of Mirtagen, and after stopping treatment with these medicines, increase the dose of Mirtagen.

Medicines that decrease the level of mirtazapine in the blood:

The use of similar medicines (SSRIs) during pregnancy may increase the risk of a severe condition in children, called persistent pulmonary hypertension of the newborn (PPHN), which causes rapid breathing and cyanosis.
Symptoms usually start within 24 hours of birth.
If the above symptoms occur in the child, the patient should immediately contact the midwife or doctor.

If any of the following symptoms occur, the patient should stop taking Mirtagen and immediately contact their doctor or go to the emergency room

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 contractions, chills, increased reflexes, anxiety, mood changes, loss of consciousness.
  In very rare cases, these may be symptoms of serotonin syndrome.
• thoughts of self-harm or suicide or suicidal attempts
• red skin lesions on the torso in the form of target-like spots or round patches, often with blisters in the center; skin peeling; ulcers of the mucous membranes of the mouth, throat, nose, eyes, and genitals.
  These types of severe skin rashes may be preceded by fever and flu-like symptoms (Stevens-Johnson syndrome, toxic epidermal necrolysis)
• widespread rash, high fever, and swollen lymph nodes (DRESS or drug hypersensitivity syndrome)
• infection symptoms such as sudden high fever, sore throat, mouth ulcers (agranulocytosis).
  Mirtazapine may cause blood disorders (bone marrow suppression).
  Some people become less resistant to infections because mirtazapine may 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 a feeling 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.
