Zolkar is used to treat patients with schizophrenia when the use of other medications has not been effective.
Schizophrenia is a mental illness that involves disorders of thought, emotional reactions, and behavioral disorders. You can only use this medication if you have already tried at least two other neuroleptic medications, including one of the new atypical neuroleptics to treat schizophrenia, and these medications have not responded, or have caused severe adverse reactions that cannot be treated.
This medication is also indicated to treat thought disorders, emotional reactions, and severe behavioral disorders that occur in Parkinson's disease, when other treatments have not been effective.
Do not take Zolkar:
Tell your doctor and do not take Zolkar if any of the above circumstances apply to you.
Zolkar should not be administered to anyone who is unconscious or in a coma.

Medical examinations and blood tests
Before starting treatment with this medication, your doctor will ask you about your medical history and perform a blood test to ensure that your white blood cell count is normal. It is essential to know this, as you need white blood cells to fight infections.
Make sure you have regular blood tests before, during, and after finishing treatment with Zolkar.
Before starting treatment, your doctor will also perform a physical examination. Your doctor may perform an electrocardiogram (ECG) to check your heart, but only if it is necessary for you or if you have any special concerns.
If you have liver disorders, you will have periodic liver function tests throughout treatment with this medication.
If you have high blood sugar levels (diabetes), your doctor may perform periodic checks of your blood sugar levels.
This medication can alter your blood lipid levels. This medication can cause weight gain. Your doctor may monitor your weight and lipid levels.
If you have a mild headache, dizziness, or weakness, or this medication makes you feel this way, be careful when getting up from a sitting or lying position, as this can increase the risk of falls.
If you need to undergo surgery or if, for any reason, you cannot walk for an extended period, inform your doctor that you are taking this medication. You may be at risk of having a blood clot (thrombosis).

Taking Zolkar with food and drinks
During treatment with this medication, do not drink alcohol.
Tell your doctor if you smoke and how often you consume beverages that contain caffeine (coffee, tea, cola). A sudden change in your smoking or caffeine consumption habits can also change the effects of this medication.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medication. Your doctor will discuss with you the benefits and possible risks of using this medication during pregnancy. Inform your doctor immediately if you become pregnant during treatment with Zolkar.
The following symptoms may appear in newborns of mothers who have used clozapine in the last trimester (the last three months of pregnancy): tremors, muscle stiffness and/or weakness, drowsiness, agitation, breathing problems, and difficulty feeding. If your baby develops any of these symptoms, you should contact your doctor.
Some women who take certain medications for mental illnesses have irregular menstrual periods or do not have menstrual periods. If this has happened to you, your menstrual period will return to normal when your medication is replaced by Zolkar. This means you should use effective contraceptives.
During treatment with this medication, you should not breastfeed your baby. Clozapine, the active substance of Zolkar, can pass into breast milk and affect the baby.
Driving and using machines
Zolkar can cause fatigue, drowsiness, and seizures, especially at the beginning of treatment. Therefore, you should avoid driving or operating machinery while you have these symptoms.
Zolkar contains lactose.
If your doctor has informed you that you have an intolerance to some sugars, contact your doctor before taking this medication.
To minimize the risk of suffering from hypotension, epileptic seizures, or drowsiness, it is necessary for your doctor to gradually increase the dose. Follow your doctor's administration instructions for Zolkar exactly. If in doubt, consult your doctor or pharmacist again.
It is essential that you do not change the dose or stop taking this medication without first asking your doctor. Continue taking the tablets for the time your doctor has indicated.
If you are a patient over 60 years old, your doctor may start treatment with a lower dose and increase your dose more gradually, as you may be more susceptible to developing some unexpected adverse reactions. (See section 2 "What you need to know before taking Zolkar").
If you cannot achieve the prescribed dose with this tablet presentation, other presentations of this medication are available to achieve the prescribed dose.
The tablet can be divided into two equal parts.
Treatment of schizophrenia
Treatment is started with 12.5 mg (half a 25 mg tablet) once or twice on the first day, followed by 25 mg once or twice on the second day. Swallow the tablet with the help of a glass of water. If you tolerate it well, your doctor will gradually increase the dose in amounts of 25 or 50 mg over 2 to 3 weeks until you reach a dose of 300 mg per day. It may be necessary to continue increasing the dose in amounts of 50 or 100 mg twice a week, or preferably once a week.
The normal daily dose of clozapine is between 200 and 450 mg, divided into several doses per day. Some people may need higher doses. Doses of up to 900 mg per day are allowed. At daily doses above 450 mg, adverse reactions (particularly seizures) may increase. Always take the minimum dose that is effective for you. Most patients should take part of the dose in the morning and another part at night. Your doctor will tell you exactly how to divide your daily dose. If your daily dose does not exceed 200 mg, you can take it as a single dose at night. Once the treatment with Zolkar is working well for you for some time, your doctor will try treatment with lower doses. You will need to take this medication for at least 6 months.
Treatment of severe thought disorders in patients with Parkinson's disease
The normal initial dose of clozapine is 12.5 mg (half a 25 mg tablet) at night. Swallow the tablet with the help of a glass of water. Your doctor will slowly increase the dose in amounts of 12.5 mg, with a maximum of two increases per week, until you reach a maximum dose of up to 50 mg at the end of the second week. Dose increments should be stopped or postponed if you feel weak, dizzy, or confused. To avoid such symptoms, your blood pressure will be measured during the first weeks of treatment.
The effective daily dose is between 25 and 37.5 mg, taken as a single dose at night. The dose can only be increased to more than 50 mg per day in exceptional cases. The maximum dose is 100 mg per day. Always take the minimum dose that is effective for you.
If you take more Zolkar than you should
If you think you have taken more Zolkar than you should, or if someone has taken some of your tablets, inform your doctor or pharmacist immediately or call the Toxicology Information Service. Phone 91 562 04 20, indicating the medication and the amount taken.
The symptoms of overdose are:
Drowsiness, fatigue, lack of energy, unconsciousness, coma, confusion, hallucinations, agitation, incoherent speech, numbness in the limbs, tremors in the hands, seizures, increased saliva production, dilated pupils, blurred vision, low blood pressure, collapse, rapid or irregular heartbeat, shallow or difficult breathing.
If you forget to take Zolkar
If you forget to take a dose, take the missed dose as soon as possible. If it is almost time for the next dose, do not take the missed dose and take the next dose at the scheduled time. Do not take a double dose to make up for the missed dose. If you have stopped taking Zolkar for more than 48 hours, do not start treatment again without first consulting your doctor.
If you interrupt treatment with Zolkar
Do not interrupt treatment with Zolkar without asking your doctor, as you may have withdrawal symptoms. These symptoms include sweating, headache, nausea (feeling dizzy), vomiting (being dizzy), and diarrhea. If you experience any of these symptoms, consult your doctor immediately. These symptoms can be followed by more severe ones unless you are treated immediately. Your initial symptoms may recur. If you need to interrupt treatment, it is recommended to gradually decrease the dose in amounts of 12.5 mg over a period of 1 to 2 weeks. Your doctor will give you instructions on how to reduce your daily dose. If you need to interrupt your treatment with Zolkar suddenly, your doctor should examine you. If your doctor decides to restart treatment and your last dose of Zolkar was 2 days or more ago, you should start again with the initial dose of 12.5 mg.
If you have any other questions about the use of this medication, ask your doctor or pharmacist.
