Clozapine
The active substance of Paxifar is clozapine, which belongs to a group of medicines called antipsychotics (medicines used to treat specific mental disorders, such as psychoses). Paxifar is used to treat patients with schizophrenia who do not respond to treatment with other medicines. Schizophrenia is a mental illness that causes disturbances in thinking, emotions, and behavior. Paxifar is recommended only for the treatment of patients who have already taken at least two different antipsychotic medicines, including new atypical antipsychotic medicines indicated for the treatment of schizophrenia, and have not responded to these medicines or have experienced severe side effects that could not be controlled. Paxifar at a strength of 25 mg, 50 mg, and 100 mg is also used to treat severe thought, emotional, and behavioral disorders in patients with Parkinson's disease, when other treatment methods have been ineffective.

Some women taking medicines for mental illnesses have irregular periods or do not have them at all. As a result of switching to Paxifar, normal menstruation may return. Therefore, women of childbearing age should use effective contraception.
Before starting treatment with Paxifar, the doctor will take a medical history and order blood tests to confirm a normal white blood cell count. This is important because the patient's body needs white blood cells to fight infection.
The doctor will also perform a physical examination before starting treatment with Paxifar. The doctor may order an electrocardiogram (ECG) to check the patient's heart function if necessary.
If the patient has liver function disorders, regular liver function tests will be performed throughout the treatment with Paxifar. If the patient has a high blood sugar level (diabetes), the doctor may order regular blood sugar tests.
Paxifar may cause changes in blood lipid levels. Paxifar may cause weight gain. The doctor may monitor the patient's weight and blood lipid levels.
If Paxifar causes the patient to feel dizzy, lightheaded, or faint, they should be careful when changing position from sitting or lying down, as these symptoms can increase the risk of falls.
If the patient needs to have surgery or is immobilized for a long time, they should discuss taking Paxifar with their doctor. There is a risk of blood clots (thrombosis).
Patients under 16 years of age should not take Paxifar, as there is limited data on the use of the medicine in this age group.
In elderly patients (60 years of age and older), the following side effects may occur more frequently during treatment with Paxifar: fainting or feeling lightheaded when changing position, dizziness, rapid heartbeat, difficulty urinating, and constipation. The patient should tell their doctor if they have a condition called dementia.

The above list is not exhaustive. The doctor or pharmacist has more information about medicines that should be used with caution with Paxifar or should be avoided during treatment with Paxifar, and they know if the medicine belongs to the listed groups. The patient should ask them about it.
The patient should not drink alcohol while taking Paxifar. The patient should tell their doctor if they smoke and how often they drink caffeinated beverages (coffee, tea, cola). Sudden changes in smoking or drinking caffeinated beverages can also change the effects of Paxifar.
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a baby, they should consult their doctor before taking this medicine. The doctor will discuss the benefits and possible risks of taking the medicine during pregnancy. The patient should tell their doctor immediately if they become pregnant while taking Paxifar. In newborns of mothers taking antipsychotic medicines in the last trimester (last three months of pregnancy), the following symptoms may occur: trembling, stiffness, and (or) muscle weakness, drowsiness, agitation, breathing problems, and difficulty feeding. If the baby develops these symptoms, the patient should contact their doctor. Some women taking medicines for mental illnesses have irregular periods or do not have them at all. As a result of switching to Paxifar, normal menstruation may return. Therefore, women of childbearing age should use effective contraception. The patient should not breastfeed while taking Paxifar. Clozapine, the active substance of Paxifar, may pass into breast milk and affect the baby.
Paxifar may cause drowsiness, sleepiness, and seizures, especially during the initial treatment period. The patient should not drive vehicles or operate machinery if they experience these symptoms.
If the patient has been diagnosed with intolerance to some sugars, they should contact their doctor before taking the medicine.
In order to minimize the risk of low blood pressure, seizures, and drowsiness, it is necessary for the doctor to gradually increase the dose of Paxifar. Paxifar should always be taken as directed by the doctor. If the patient has any doubts, they should consult their doctor or pharmacist. It is very important not to change the dose or stop taking Paxifar without consulting the doctor first. The patient should continue treatment for as long as the doctor recommends. In patients over 60 years of age, the doctor may start treatment with smaller doses and gradually increase them, as it is more likely that they will experience certain side effects (see section 2. Important information before taking Paxifar). If the recommended dose cannot be achieved with a tablet of a given strength, tablets of a different strength are available.
The usual recommended starting dose is 12.5 mg (half a 25 mg tablet) once or twice a day on the first day, and then 25 mg once or twice a day on the second day. The tablet should be swallowed with water. If the patient tolerates the treatment well, the daily dose can then be gradually increased by 25 mg to 50 mg over 2-3 weeks to achieve a target dose of up to 300 mg per day. Then, if necessary, the daily dose can be further increased by 50 mg to 100 mg at intervals of 3 to 4 days or preferably once a week. The effective daily dose is usually 200 mg or 450 mg, divided into several single doses. Some patients may need higher doses. The maximum daily dose is 900 mg. At doses above 450 mg per day, it is possible to exacerbate some side effects (in particular, seizures). The patient should always take the smallest effective dose of the medicine. Most patients take part of the dose in the morning and part in the evening. The doctor will explain how to divide the daily dose. If the daily dose is 200 mg, the patient can take it as a single dose in the evening. If the patient has been taking Paxifar for some time with good results, the doctor may try to reduce the dose. The patient should take Paxifar for at least 6 months.
The usual recommended starting dose is 12.5 mg (half a 25 mg tablet) in the evening. The tablet should be swallowed with water. Then, the doctor will gradually increase the dose by 12.5 mg, no faster than twice a week, to achieve a maximum dose of 50 mg per day within two weeks. If the patient experiences fainting, dizziness, or confusion, the dose increase should be delayed or suspended. To avoid these symptoms, the patient's blood pressure should be checked in the first weeks of treatment. The effective daily dose is usually 25 mg to 37.5 mg, taken as a single dose in the evening. Taking doses higher than 50 mg per day should only be done in exceptional cases. The maximum daily dose is 100 mg. The patient should always take the smallest effective dose of the medicine. In the treatment of psychiatric disorders in Parkinson's disease, only 25 mg, 50 mg, and 100 mg tablets are used.
If the patient has taken too many tablets, they should contact their doctor or call emergency services immediately. Symptoms of overdose: drowsiness, fatigue, lack of energy, loss of consciousness, coma, confusion (disorientation), hallucinations, agitation, chaotic speech, muscle stiffness, hand tremors, seizures (convulsions), excessive salivation, dilated pupils, blurred vision, low blood pressure, collapse, rapid or irregular heartbeat, shallow or difficult breathing.
If the patient misses a dose, they should take it as soon as possible. However, they should not take the medicine if it is almost time for the next dose. In this case, they should take the next dose at the usual time. The patient should not take a double dose to make up for the missed dose. If the patient forgets to take Paxifar for 48 hours or more, they should contact their doctor immediately.
The patient should not stop taking Paxifar without consulting their doctor, as withdrawal reactions may occur. These include: sweating, headache, nausea, vomiting, and diarrhea. If the patient experiences any of these symptoms, they should tell their doctor immediately.

The doctor will inform the patient how to reduce the daily dose. If it is necessary to stop taking Paxifar immediately, the patient should consult their doctor. If the doctor decides to restart treatment with Paxifar and the patient has taken the last dose of Paxifar more than two days ago, the starting dose will be 12.5 mg.
