Contents of the pack and other information

1. What Clozapina Stada is and what it is used for

The active substance of Clozapina Stada is clozapine, which belongs to a group of medicines called antipsychotics (medicines used to treat specific mental disorders such as psychosis).

Clozapine is used to treat patients with schizophrenia when other medicines have not worked. Schizophrenia is a mental illness involving disturbances in thought, emotional reactions, and behavioural disorders. You may only use this medicine if you have already tried at least two other antipsychotic medicines, including one of the newer atypical antipsychotics for treating schizophrenia, and these medicines have either been ineffective or caused serious adverse reactions that cannot be managed.

Clozapine is also indicated for the treatment of severe disturbances in thought, emotional reactions, and behavioural disorders occurring in Parkinson's disease, when other medicines have not been effective.

2. What you need to know before starting to take Clozapine Stada

DO NOT take Clozapina Stada if you:

are allergic to clozapine or to any of the other components of this medicine (listed in section 6).
cannot have regular blood tests performed.
have been informed that you have a low white blood cell count (e.g., leukopenia or agranulocytosis), especially if it was caused by other medicines. This does not apply if your low white blood cell count was due to previous chemotherapy.
previously had to stop taking clozapine because it caused you serious adverse reactions (e.g., agranulocytosis or any heart problems).
are being or have been treated with long-acting depot injections of antipsychotics.
have or have had a bone marrow disorder.
have uncontrolled epilepsy (seizures or fits).
have had severe mental disorders caused by alcohol or other medicines (e.g., narcotics).
have loss of consciousness and marked drowsiness.
have circulatory collapse that may occur as a result of severe shock.
have severe kidney disease.
have myocarditis (inflammation of the heart muscle).
have any other serious heart disease.
have symptoms of active liver disease such as jaundice (yellowing of the skin and eyes, feeling unwell, and loss of appetite).
have any other severe liver disease.
have paralytic ileus (intestinal obstruction, your bowel does not work properly and you have severe constipation).
are taking any medicine that impairs the function of your bone marrow.
are taking any medicine that reduces the number of white blood cells in your blood.

Inform your doctor and do not take clozapine if any of the above conditions apply to you.

Clozapine must not be given to anyone who is unconscious or in a coma.

Warnings and precautions

The safety measures mentioned in this section are very important. You must follow them to minimize the risk of serious adverse reactions that could be life-threatening.

Inform your doctor before starting treatment with clozapine if you have or have had any of the following conditions:

blood clots or a family history of blood clots, as this type of medicine has been associated with blood clot formation.
increased pressure in the eye (glaucoma).
diabetes. Elevated blood glucose levels (sometimes markedly) have been reported in patients with or without a medical history of diabetes mellitus (see section 4).
prostate problems or difficulty urinating.
any heart, kidney, or liver disease.
chronic constipation or are taking medicines that cause constipation (such as anticholinergics).
controlled epilepsy.
diseases of the large intestine.
abdominal surgery.
heart disease or a family history of an abnormal heart conduction condition known as “QT interval prolongation.”
risk of stroke, for example, if you have very high blood pressure, cardiovascular problems, or blood vessel problems in the brain.

Inform your doctor immediately before taking your next clozapine tablet if:

you have signs of a cold, fever, flu-like symptoms, sore throat, or any other infection. You will need an urgent blood test to determine whether these symptoms are related to the medicine.
you experience a sudden increase in body temperature, muscle stiffness that may lead to altered consciousness (neuroleptic malignant syndrome), as this may be a serious adverse reaction requiring immediate treatment.
you have a fast or irregular heartbeat, even at rest, palpitations, breathing difficulties, chest pain, or unusual tiredness. Your doctor should perform a heart check and, if necessary, refer you immediately to a cardiologist.
you have nausea (feeling sick), vomiting (being sick), and/or loss of appetite. Your doctor should examine your liver.
you have severe constipation. Your doctor should treat you to prevent further complications.
you experience constipation, abdominal pain, abdominal tenderness, fever, abdominal distension, and/or bloody diarrhea. Your doctor will need to examine you.

Medical examinations and blood tests

Before starting treatment with clozapine, your doctor will ask you about your medical history and perform a blood test to ensure that your white blood cell count is normal. This is important because your body needs white blood cells to fight infections.

Make sure you have regular blood tests performed before starting treatment, during treatment, and after stopping treatment with clozapine.

Your doctor will inform you exactly when and where these tests will be carried out. You may only take clozapine if you have a normal blood count.
Clozapine may cause a serious decrease in white blood cells in your blood (agranulocytosis). Only regular blood testing allows your doctor to determine whether you are at risk of developing agranulocytosis (see section 4).
Blood tests must be performed weekly during the first 18 weeks of treatment, and then at least once a month during the following 34 weeks.
After 12 months of treatment, blood tests should be performed every 12 weeks for one year, and then annually, provided no decrease in white blood cell count has been detected.
If a decrease in white blood cell count occurs, clozapine treatment must be stopped immediately. Your white blood cell count should return to normal levels.
You must continue to have blood tests for 4 weeks after stopping clozapine treatment, especially if treatment is completely discontinued for hematological reasons (i.e., agranulocytosis), or if monitoring duration has been less than 2 years, or if you have a history of neutropenia that did not lead to discontinuation of treatment.

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 necessary or if you have any specific concerns.

If you have liver problems, periodic liver function tests will be performed throughout clozapine treatment.

If you have high blood glucose levels (diabetes), your doctor may periodically check your glucose levels.

Clozapine may alter lipid levels in the blood. Clozapine may cause weight gain. Your doctor may monitor your weight and lipid levels.

If you experience mild headache, dizziness, or weakness, or if clozapine makes you feel this way, be careful when getting up from a sitting or lying position, as this may increase your risk of falling.

If you need to undergo surgery or for any reason are unable to walk for a prolonged period, inform your doctor that you are taking clozapine. You may be at risk of developing thrombosis (blood clot in a vein).

Children and adolescents under 16 years of age

If you are under 16 years of age, you must not take clozapine, as there is insufficient information on its use in this age group.

Use in elderly patients (60 years and older)

Patients aged 60 years and older may be more susceptible to the following adverse effects during clozapine treatment:

weakness or mild headache after changing position
dizziness
rapid heart rate
urinary retention
constipation

Inform your doctor or pharmacist if you have a condition called dementia.

Other medicines and Clozapina Stada

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription or herbal remedies. You may need to take different doses or different medicines.

Do not take clozapine together with other medicines that impair the proper functioning of the bone marrow and/or reduce the number of blood cells produced by the body, such as:

carbamazepine, a medicine used for epilepsy.
certain antibiotics: chloramphenicol, sulfonamides such as cotrimoxazole.
certain pain medicines: analgesics of the pyrazolone group such as phenylbutazone.
penicillamine, a medicine used to treat rheumatoid arthritis.
cytotoxic agents, medicines used in chemotherapy.
long-acting depot injections of antipsychotic medicines.

These medicines increase your risk of developing agranulocytosis (deficiency of white blood cells in the blood).

Taking clozapine together with other medicines may affect the proper action of clozapine and/or the other medicines. Inform your doctor if you intend to take, are currently taking (even if treatment is about to end), or have recently stopped taking any of the following medicines:

medicines used to treat depression, such as lithium, fluvoxamine, tricyclic antidepressants, MAO inhibitors, citalopram, paroxetine, fluoxetine, and sertraline.
other antipsychotic medicines used to treat mental illnesses, such as perazine.
benzodiazepines and other medicines used to treat anxiety or sleep disorders.
narcotics and other medicines that may affect your breathing.
medicines used to control epilepsy, such as phenytoin and valproic acid.
medicines used to treat high or low blood pressure, such as adrenaline and noradrenaline.
warfarin, a medicine used to prevent blood clotting.
antihistamines, medicines used for colds and allergies, such as hay fever.
anticholinergic medicines, used to relieve stomach cramps, spasms, and dizziness.
medicines used to treat Parkinson's disease.
digoxin, a medicine used to treat heart problems.
medicines used to treat fast or irregular heart rate.
some medicines used to treat stomach ulcers, such as omeprazole or cimetidine.
some antibiotics, such as erythromycin and rifampicin.
some medicines used to treat fungal infections (such as ketoconazole) or viral infections (such as protease inhibitors, used to treat HIV infections).
atropine, a medicine that may be used in certain eye drops or in cough and cold preparations.
adrenaline, a medicine used in emergency situations.
hormonal contraceptives (birth control pills).

This list is not complete. Your doctor and pharmacist have more information about medicines that should be used with caution or avoided while taking clozapine. They also know whether the medicines you are taking belong to any of the groups listed above.

Discuss this with them.

Taking Clozapina Stada with food and drinks

Do not drink alcohol during treatment with clozapine.

Inform your doctor if you smoke and how frequently you consume caffeine-containing drinks (coffee, tea, cola drinks). Sudden changes in your smoking habits or in your consumption of caffeine-containing drinks may also alter the effects of clozapine.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine.

Pregnancy

Your doctor will discuss with you the benefits and possible risks of using this medicine during pregnancy.

Inform your doctor immediately if you become pregnant during clozapine treatment.

The following symptoms may occur in newborn babies of mothers who have taken clozapine during the third trimester (the last three months of pregnancy):

tremor
muscle stiffness and/or weakness
drowsiness
agitation
breathing difficulties
feeding difficulties

If your baby develops any of these symptoms, you should contact your doctor.

Breastfeeding

You must not breastfeed during treatment with clozapine. Clozapine, the active substance in this medicine, may pass into breast milk and affect the baby.

Fertility

Some women who take certain medicines for mental illnesses may have irregular or absent menstrual periods. If this has happened to you, your menstrual cycle may return to normal when your medication is switched to clozapine. This means you should use effective contraception.

Driving and using machines

Clozapine may cause tiredness, drowsiness, and seizures, especially at the beginning of treatment. Therefore, you should avoid driving or operating machinery while experiencing these symptoms.

Clozapine may cause symptoms such as drowsiness, dizziness, or vision disturbances and may reduce reaction time. These effects, as well as the illness itself, may impair your ability to drive vehicles or operate machinery. Therefore, do not drive, operate machinery, or engage in other activities requiring special attention until your doctor has assessed your response to this medicine.

Clozapina Stada contains lactose

This medicine contains lactose. If your doctor has informed you that you have an intolerance to certain sugars, consult with your doctor before taking this medicine.

3. How to take Clozapina Stada

To minimize the risk of seizures, drowsiness, or hypotension as much as possible, your doctor must gradually increase your dose. Follow exactly the administration instructions given by your doctor. If in doubt, consult your doctor or pharmacist again.

It is important that you do not change the dose or stop taking clozapine without first asking your doctor.

Continue taking clozapine for as long as your doctor has instructed. If you are 60 years of age or older, your doctor may start you on a lower dose and increase it more gradually, as you may be more susceptible to certain unexpected adverse reactions. (See section 2, "What you need to know before starting to take Clozapina Stada").

If with this tablet formulation you cannot achieve the prescribed dose, other formulations of this medicine are available to reach the prescribed dose.

Method of administration

Oral use.

Swallow the tablet with water.

Treatment of schizophrenia

Unless your doctor prescribes a different dose, treatment is initiated 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. If well tolerated, your doctor will gradually increase the dose by increments of 25 or 50 mg over 2 to 3 weeks until reaching a dose of 300 mg per day. It may be necessary to continue increasing the dose by 50 or 100 mg twice weekly, or preferably once weekly.

The normal daily dose of clozapine is between 200 and 450 mg, divided into several doses per day. Some individuals may require higher doses. Doses up to 900 mg per day are permitted.

At daily doses exceeding 450 mg, adverse reactions (particularly seizures) may increase. Always take the lowest effective dose for you. Most patients should take part of the dose in the morning and 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 may take it as a single dose at night. Once clozapine treatment has been effective for some time, your doctor may test lower doses. You will need to take clozapine for at least 6 months.

Treatment of severe thought disorders in patients with Parkinson's disease

Unless your doctor prescribes a different dose, the usual initial dose of clozapine is 12.5 mg (half a 25 mg tablet) at night.

Your doctor will slowly increase the dose by increments of 12.5 mg, with a maximum of two increases per week, until reaching a maximum dose of up to 50 mg by the end of the second week. Dose increases should be stopped or postponed if you feel weak, dizzy, or confused. To avoid such symptoms, your blood pressure will be monitored during the first weeks of treatment.

The effective daily dose ranges between 25 and 37.5 mg, taken as a single nightly dose. Doses exceeding 50 mg per day are only allowed in exceptional cases. The maximum dose is 100 mg per day. Always take the lowest effective dose for you.

If you take more Clozapina Stada than you should

If you think you have taken more clozapine than you should, or if someone has taken any of your tablets, inform your doctor or pharmacist immediately.

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately or call the Toxicology Information Service at telephone number: 91 562 04 20, indicating the medicine and the amount ingested.

Symptoms of overdose include:

Drowsiness, fatigue, lack of energy, unconsciousness, coma, confusion, hallucinations, agitation, incoherent speech, numbness in the limbs, hand tremors, seizures, increased salivation, pupil dilation, blurred vision, low blood pressure, collapse, rapid or irregular heartbeat, shallow breathing, or difficulty breathing.

If you forget to take Clozapina Stada

If you forget to take a dose, take it as soon as possible. If it is almost time for your 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 a missed one. Contact your doctor as soon as possible if you have stopped taking clozapine for more than 48 hours.

If you stop taking Clozapina Stada

Do not stop clozapine treatment without consulting your doctor, as you may experience withdrawal symptoms. These symptoms include sweating, headache, nausea (feeling sick), vomiting (being sick), and diarrhea. If you experience any of these symptoms, consult your doctor immediately. These symptoms may be followed by more severe ones unless you are treated promptly. Your original symptoms may also return. If treatment must be discontinued, it is recommended to gradually reduce the dose by 12.5 mg increments over a period of 1 to 2 weeks.

Your doctor will give you instructions on how to reduce your daily dose. If you must stop treatment abruptly, your doctor should examine you.

If your doctor decides to restart clozapine treatment and your last dose of clozapine was two days or more ago, treatment should be restarted at the initial dose of 12.5 mg.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.

4. Possible adverse effects

Like all medicines, clozapine may produce adverse effects, although not everyone experiences them.

Some adverse effects may be serious and require immediate medical attention:

Contact your doctor immediately before taking your next clozapine tablet if you experience any of the following:

Severe constipation. Your doctor should treat this to prevent further complications.
Fast heartbeat.

Common (affects up to 1 in 10 people)

Signs of a cold, fever, flu-like symptoms, sore throat, or any other infection. You will need an urgent blood test to check whether your symptoms are related to your medication.
Epileptic seizures.
- Sudden fainting or sudden loss of consciousness with muscle weakness (syncope).

Uncommon (affects up to 1 in 100 people)

A sudden increase in body temperature, muscle rigidity that may progress to altered consciousness (neuroleptic malignant syndrome), as this may be a serious adverse effect requiring immediate treatment.

Rare (affects up to 1 in 1,000 people)

Signs of respiratory tract infection or pneumonia such as fever, cough, difficulty breathing, or wheezing (noisy breathing).
Severe burning pain in the upper abdomen radiating to the back, accompanied by nausea and vomiting due to inflammation of the pancreas.
Fainting and muscle weakness due to a significant drop in blood pressure (circulatory collapse).
Difficulty swallowing (which may lead to inhalation of food).
Nausea (feeling sick), vomiting (being sick), and/or loss of appetite. Your doctor will need to check your liver.
Signs of obesity or worsening obesity.
Interruption of breathing with or without snoring during sleep.

Rare (affects up to 1 in 1,000 patients) or very rare (affects up to 1 in 10,000 people)

Fast and irregular heartbeat, even at rest, palpitations, breathing difficulties, chest pain, or unusual tiredness. Your doctor should perform a heart check and, if necessary, refer you immediately to a cardiologist.
