6. Contents of the pack and other information

• The short-term treatment of the symptoms of severe anxiety in adults
• Epilepsy (fits) in adults and children aged over 2 years (together with other treatments).
• Short term treatment of hyperarousal and agitation in patients with schizophrenic or other psychotic illness (only in combination with other treatments as benzodiazepines alone are not effective in these patients).

• You are allergic to clobazam, other benzodiazepine medicines or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.
• You are breast-feeding.
• You have ever had problems with drugs or alcohol dependence in the past.
• You suffer from an illness that causes muscle weakness (called ‘myasthenia gravis’).
• You have severe liver problems.
• You have severe breathing problems.
• You stop breathing for short periods during sleep (called ‘sleep apnoea syndrome’).
• The patient is under 2 years old, except if the doctor decides this is necessary.

Do not take if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Zacco.

Note: Make sure that you receive the same clobazam medicine every time you collect your prescription unless your doctor has agreed to change to a different clobazam medicine. If the appearance of this medicine is not the same as usual or if the dosage instructions have changed, speak to your doctor or pharmacist as soon as possible to make sure you have the right medicine.

Talk to your doctor or pharmacist before taking Zacco if:

• You have problems with controlling your movements (called ‘spinal or cerebellar ataxia’).
• You have depression, irrational fears and obsessions.
• You have delusions (believing things which are not true) or hallucinations (sensing things which are not there).
• You have liver or kidney problems. Your doctor will decide whether to reduce the dose of Zacco.
• You have ever become dependent upon another drug or alcohol. Alcohol should not be taken during treatment with Zacco as there is an increased risk of experiencing side effects.
• You are over 65. This is due to increased sensitivity to adverse reactions in the elderly such as drowsiness, dizziness and muscle weakness. There is also an increased risk of fall that may result in serious injury.
• You have difficulty digesting medicines. In some patients, liver may not metabolise (break down) medicines adequately. In these patients the medicine may remain in the body for a longer period of time. This may result in side effects. If you are known to poorly metabolise certain medicines please speak to your doctor.

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Zacco.

Suicidal thoughts

Tell your doctor straight away if you start thinking about suicide or harming yourself. Some patients have had suicidal thoughts while taking medicines containing clobazam, especially if they were also depressed.

Psychotic or ‘Paradoxical’ reactions

It is known that with the use of clobazam restlessness, agitation, irritability, aggression, delusions, rage, nightmares, hallucinations, deceptive thoughts (psychosis), inappropriate behaviour and other adverse behavioural effects may occur. If this happens you should stop taking Zacco and contact your doctor. These reactions are more common in children and elderly patients.

Dependence, withdrawal and tolerance

You may become dependent on Zacco if you take it for a long period of time or with high dose, particularly if you have a history of heavy alcohol or drug use. This means that you may feel that you need to continue treatment with Zacco in order to feel well (known as psychological dependence). You should therefore take Zacco for as short time as possible.

If you suddenly stop taking Zacco you may experience worsening of the symptoms you were originally being treated for, as well as mood changes, anxiety, sleep disturbance, headache, increased dreaming, tension, confusion, excitability, hallucinations, muscle pain, numbness of the limb, tingling, sweating, tremor, nausea, sensitivity to light, increased sensitivity to sound, sensitivity to light or restlessness.

This is known as withdrawal symptoms and can be avoided by slowly reducing your dose. If you are worried about dependence or withdrawal please talk to your doctor.

If you take Zacco for a long period of time for treatment of epilepsy it is possible that you may become tolerant to it, meaning that it will not be as effective as it was when you first started taking it. If you feel that Zacco is no longer helping to control your symptoms please talk to your doctor, they may suggest you take a short break from this medicine.

Breathing difficulties

Zacco may cause respiratory depression, particularly when administered at high doses. Tell your doctor if you have respiratory failure, your doctor will decide whether to reduce the dose. In case of severe respiratory disturbance, clobazam may not be used.

Serious skin problems

Zacco may cause serious skin reactions.

You should talk to your doctor if you develop any rash unless it is clearly not drug related.

Children

Zacco should only be used in children from 1 month to 2 years old, under exceptional situations, where there is a clear epilepsy indication.

Please tell your doctor or pharmacist if you are taking or have recently taken or might take any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because Zacco can affect the way some other medicines work. Also some medicines can affect the way Zacco works.

In particular, tell your doctor if you are taking any of the following:

• Medicines for epilepsy (such as phenytoin, carbamazepine, stiripentol or valproic acid).
• Medicines for depression (Monoamine Oxidase Inhibitors (MAOIs) such as phenelzine and isocarboxazid; tricyclic anti-depressants such as amitriptyline and nortriptyline; trazodone; Selective Serotonin Re-uptake Inhibitors (SSRIs) such as fluvoxamine and paroxetine).
• Medicines for severe mental illness called ‘antipsychotics’ (such as chlorpromazine, haloperidol, clozapine and pimozide).
• Painkillers (such as medicines containing codeine, dihydrocodeine or morphine).
• Sleeping tablets (such as zolpidem).
• Tranquilisers (such as diazepam, temazepam or lorazepam).
• Muscle relaxants (such as baclofen).
• Antihistamines that make you sleepy (such as chlorphenamine, promethazine or diphenhydramine).
• Lithium - used for a mental illness called ‘manic-depressive illness’ (mood changes between a state of high excitability or exaggerated emotions and depression).
• Cimetidine - used to treat ulcers and heartburn.
• Erythromycin - used to treat infections caused by bacteria.
• Omeprazole - used to treat the symptoms of acid reflux such as heartburn or acid regurgitation.
• Ticlopidine - an antiplatelet medication used in patients with an increased risk of stroke.
• Fluconazole - used in the treatment of fungal conditions.
• Dextromethorphan - used to relieve dry, irritating coughs.
• Nebivolol - medicine used to treat high blood pressure.

Concomitant use of Zacco and opioids (strong pain killers, medicines for substitution therapy and some cough medicines) increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.

However, if your doctor does prescribe Zacco together with opioids the dose and duration of concomitant treatment should be limited by your doctor.

Please tell your doctor about all opioid medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.

If you are not sure if any of the above apply to you talk to your doctor or pharmacist.

If you are going to have an anaesthetic, tell your doctor or anaesthetist that you are taking Zacco. This is because your doctor may need to change the amount of anaesthetic or muscle relaxants to give you.

Do not drink alcohol while taking Zacco. This is because there is an increased risk of sleepiness and other side effects.

Pregnancy

Use of this medicine is not recommended during pregnancy and in women of childbearing potential not using contraception.

If you discover that you are pregnant or are planning to have a baby, consult your doctor right away to re-assess the need for treatment.

Do not stop taking Zacco without talking to your doctor.

A large amount of data has not shown evidence of malformations associated with the use of benzodiazepines. However, some studies have shown a potentially increased risk of cleft lip and palate in newborn babies compared to that in the general population.

Cleft lip and palate (sometimes called “harelip”) is a deformation at birth caused by incomplete fusion of the palate and upper lip.

Reduced fetal movement and fetal heart rate variability may occur after taking Zacco during the second and/or third trimester of pregnancy.

If Zacco is taken at the end of pregnancy or during childbirth, your baby may show drowsiness (sedation), muscle weakness (hypotonia or floppy infant syndrome), a drop in body temperature (hypothermia), difficulty feeding (problems suckling causing poor weight gain) and breathing problems (respiratory depression sometimes severe).

If taken regularly in late pregnancy, your baby may get withdrawal symptoms such as agitation or shaking. In this case the newborn should be closely monitored during the postnatal period.

Zacco has major influence on the ability to drive and use machines. You may feel sleepy or have concentration or memory problems after taking this medicine. You may also experience double vision or you may react more slowly to things. If this happens, do not drive or use any tools or machines.

The medicine can affect your ability to drive as it may make you sleepy or dizzy.

• Do not drive while taking this medicine until you know how it affects you.
• It is an offence to drive if this medicine affects your ability to drive.
• However, you would not be committing an offence if:
  • The medicine has been prescribed to treat a medical or dental problem and
  • You have taken it according to the instructions given by the prescriber or in the information provided with the medicine and
  • It was not affecting your ability to drive safely.

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

This medicine contains methyl parahydroxybenzoate (E218), which may cause allergic reactions (possibly delayed).
