Zaponex®25 mg Tablets Zaponex®100 mg Tablets – patient leaflet, side effects, dosage

1 What Zaponex is and what it is used for

If you already feel that Zaponex makes you light-headed, dizzy or faint, be careful when getting up from a sitting or lying position, as this may increase the possibility of falling.

The active ingredient of Zaponex is clozapine which belongs to a group of medicines called antipsychotics (medicines that are used to treat specific mental disorders such as psychosis).

If you have to undergo surgery or if for some reason you are unable to walk around for a long time, discuss with your doctor the fact that you are taking Zaponex. You may be at risk of thrombosis (blood clotting within a vein).

Zaponex is used to treat people with schizophrenia in whom other medicines have not worked. Schizophrenia is a mental illness which affects how you think, feel and behave. You should only use this medicine if you have already tried at least two other antipsychotic medicines, including one of the newer atypical anti-psychotics, to treat schizophrenia, and these medicines did not work, or caused severe side effects that cannot be treated.

Children and adolescents under 16 years

If you are under 16 years of age you should not use Zaponex as there is not enough information on its use in that age group.

Older people (aged 60 years and over)

Older people (aged 60 years and over) may be more likely to have the following side effects during treatment with Zaponex: faintness or light-headedness after changing position, dizziness, fast heart beat, difficulty in passing urine, and constipation.

Zaponex is also used to treat severe disturbances in the thoughts, emotions and behaviour of people with Parkinson’s disease in whom other medicines have not worked.

Tell your doctor or pharmacist if you suffer from a condition called dementia.

2 What you need to know before you take Zaponex

Other medicines and Zaponex

Do not take Zaponex if you:

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This includes medicines obtained without a prescription or herbal therapies. You might need to take different amounts of your medicines or take different medicines.

• are allergic (hypersensitive) to clozapine or any of the other ingredients of Zaponex (see section 6) • are not able to have regular blood tests • have ever been told you have a low white blood cell count (e.g. leukopenia or agranulocytosis), especially if this was caused by medicines. This does not apply if you have had low white blood cell count caused by previous chemotherapy.

  Do not take Zaponex together with medicines that stop the bone marrow from working properly and/or decrease the number of blood cells produced by the body, such as:

• suffer from bone marrow disease or have ever suffered from bone marrow disease

  • carbamazepine, a medicine used in epilepsy • certain antibiotics: chloramphenicol, sulphonamides such as co-trimoxazole
• use any medicine that stops your bone marrow from working properly

• use any medicine that reduces the number of white cells in your blood

  • certain painkillers: pyrazolone analgesics such as phenylbutazone

• had to stop using Zaponex previously because of severe side effects (e.g. agranulocytosis or heart problems)

  • penicillamine, a medicine used to treat rheumatic joint inflammation
  • cytotoxic agents, medicines used in chemotherapy • long-acting depot injections of antipsychotic medicines.

• suffer from uncontrolled epilepsy (seizures or fits) • have an acute mental illness caused by alcohol or drugs (e.g. narcotics)

  These medicines increase your risk of developing agranulocytosis (lack of white blood cells).

• suffer from myocarditis (an inflammation of the heart muscle)

• suffer from any other severe heart disease • suffer from any severe kidney disease

  Taking Zaponex at the same time as another medicine may affect how well Zaponex and/or the other medicine works.

• have symptoms of active liver disease such as jaundice (yellow colouring of the skin and eyes, feeling sick and loss of appetite)

  Tell your doctor if you plan to take, if you are taking (even if the course of treatment is about to end) or if you have recently had to stop taking any of the following medicines:

• suffer from any other severe liver disease • suffer from reduced consciousness and severe drowsiness

  • medicines used to treat depression such as lithium, fluvoxamine, tricyclic antidepressants, MAO inhibitors, citalopram, paroxetine, fluoxetine, and sertraline
• suffer from circulatory collapse which may occur as a result of severe shock

• suffer from paralytic ileus (your bowel does not work properly and you have severe constipation) • are being or have been treated with long-acting depot injections of antipsychotics.

  • other antipsychotic medicines used to treat mental illnesses
  • benzodiazepines and other medicines used to treat anxiety or sleep disturbances

If any of the above applies to you, tell your doctor and do not take Zaponex.

• narcotics and other medicines which can affect your breathing

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

• 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

Warnings and Precautions

• warfarin, a medicine used to prevent blood clots • antihistamines, medicines used for colds or allergies such as hay fever

The safety measures mentioned in this section are very important. You must comply with them to minimise the risk of serious life-threatening side effects.

• anticholinergic medicines, which are used to relieve stomach cramps, spasms and travel sickness • medicines used to treat Parkinson’s disease • digoxin, a medicine used to treat heart problems • medicines used to treat a fast or irregular heart beat • some medicines used to treat stomach ulcers, such as omeprazole or cimetidine

Before you start treatment with Zaponex, tell your doctor if you have or ever had:

• blood clots or family history of blood clots, as medicines like these have been associated with formation of blood clots

  • some antibiotic medicines, such as erythromycin and rifampicin

• glaucoma (increased pressure in the eye) • diabetes. Elevated (sometimes considerably) blood sugar levels have occurred in patients with or without diabetes mellitus in their medical history (see section

  • 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 which may be used in some eye drops or cough and cold preparations

4)

• prostate problems or difficulty in urinating • any heart, kidney or liver disease

  • adrenaline, a medicine used in emergency situations. • hormonal contraceptives (birth control medicines). This list is not complete. Your doctor and pharmacist have more information on medicines to be careful with or to avoid while taking Zaponex. They will also know if the medicines you are taking belong to the listed groups. Speak to them.
• chronic constipation or if you are taking medicines which cause constipation (such as anticholinergics) • galactose intolerance, lactase deficiency or glucose-galactose malabsorption
• controlled epilepsy
• large intestine diseases

  Do not drink alcohol during treatment with Zaponex.

• a risk for having stroke, for example if you have high blood pressure, cardiovascular problems or blood vessel problems in the brain

  Tell your doctor if you smoke and how often you have drinks containing caffeine (coffee, tea, cola). Sudden changes in your smoking habits or caffeine drinking habits can also change the effects of Zaponex.

• a severe skin rash or skin peeling, blistering and/or mouth sores after taking Zaponex. This medicine can cause serious skin reactions. Stop using clozapine and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions.

  Pregnancy and breast-feeding

  If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Your doctor will discuss with you the benefits and possible risks of using this medicine during pregnancy. Tell your doctor immediately if you become pregnant during treatment with Zaponex.

Tell your doctor immediately before taking the next Zaponex tablet if you:

• get signs of a cold, fever, flu-like symptoms, sore throat or any other infection. You will have to have an urgent blood test to check if your symptoms are related to your medicine.

  Pregnancy

  The following symptoms may occur in newborn babies, of mothers that have used Zaponex in the last trimester (last three months of their pregnancy): shaking, muscle stiffness and/or weakness, sleepiness, agitation, breathing problems, and difficulty in feeding. If your baby develops any of these symptoms you may need to contact your doctor.

• have a sudden rapid increase in body temperature, rigid muscles which may lead to unconsciousness (neuroleptic malignant syndrome) as you may be experiencing a serious side effect which requires immediate treatment.

• have fast and irregular heartbeat, even when you are at rest, palpitations, breathing problems, chest pain or unexplained tiredness. Your doctor will need to check your heart and if necessary refer you to a cardiologist immediately.

  Breast-feeding

  Do not breast-feed during treatment with Zaponex. Clozapine, the active substance of Zaponex, may pass into your milk and affect your baby.

• experience nausea (feeling sick), vomiting (being sick) and/or loss of appetite. Your doctor will need to check your liver.

  Women of childbearing potential

• experience constipation, abdominal pain, abdominal tenderness, fever, bloating and/or bloody diarrhoea. Your doctor will need to examine you.

  Some women taking some medicines to treat mental illnesses have irregular or no periods. If you have been affected in this way, your periods might return when your medicine is changed to Zaponex. This means you should use effective contraception.

• develop signs and symptoms of appendicitis; these may include intense and worsening abdominal pain that begins near the navel and moves to the lower right side, made worse by movement, coughing or pressing the area. Other signs can include constipation, abdominal swelling malaise, mild fever, vomiting, loss of appetite or diarrhoea. You will need an urgent medical examination by your doctor.

  Driving and using machines

  Zaponex might cause tiredness, drowsiness and seizures, especially at the beginning of treatment. You should not drive or operate machines while you have these symptoms.

  Zaponex contains lactose

Medical check-ups and blood tests

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking Zaponex.

Before you start taking Zaponex, your doctor will ask about your medical history and do a blood test to ensure that your white blood cell count is normal. It is important to find this out, as your body needs white blood cells to fight infections.

3 How to take Zaponex

Make sure that you have regular blood tests before you start treatment, during treatment and after you stop treatment with Zaponex.

In order to minimise the risk of low blood pressure, seizures and drowsiness it is necessary that your doctor increases your dose gradually. Always take Zaponex tablets exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

• Your doctor will tell you exactly when and where to have the tests. Zaponex may only be taken if you have a normal blood cell count.

• Zaponex can cause a serious decrease in the number of white cells in your blood (agranulocytosis). Only regular blood tests can tell the doctor if you are at risk of developing agranulocytosis.

  It is important that you do not change your dose or stop taking Zaponex without asking your doctor first. Continue taking the tablets for as long as your doctor tells you. If you are 60 years or older, your doctor may start you on a lower dose and increase it more gradually because you might be more likely to develop some unwanted side effects (see section 2 “Before you take Zaponex”).

• During the first 18 weeks of treatment, tests are needed once a week. Between weeks 18 and 52, tests are needed at least every 2 weeks. Afterwards, tests are needed at least once a month.

• If there is a decrease in the number of white blood cells, you will have to stop Zaponex treatment immediately. Your white blood cells should then return to normal.

  If the dose you are prescribed cannot be achieved with this strength tablet, other strengths of this medicinal product are available to achieve the dose.

• You will need to have blood tests for another 4 weeks after the end of Zaponex treatment.

  Zaponex tablets can be divided into equal doses.

Your doctor will also do a physical examination before starting treatment. Your doctor may do an electro-cardiogram (ECG) to check your heart, but only if this is necessary for you, or if you have any special concerns.

In order to avoid such symptoms your blood pressure will be measured during the first weeks of treatment.

• extremely intense and serious skin reactions, such as drug rash with eosinophilia and systemic symptoms (DRESS syndrome), have been reported during use of clozapine.
