Patient leaflet - Clobazam Milpharm 10 mg tablets

1. What Clobazam Milpharm is and what it is used for

This medicine has been prescribed for you for:

  • Severe anxiety over a short time
  • Epilepsy (fits) over a longer time
  • Mental illness such as schizophrenia

    (in combination with other

    treatments)

It contains clobazam which belongs to a class of medicines called

benzodiazepines.

This medicine has been prescribed to you and should not be given to anyone else.

Benzodiazepines can cause

dependence, tolerance and addiction, and you may get withdrawal symptoms if you stop taking it or reduce the dose suddenly. Your prescriber should have explained how long you will be taking it for and, when it is appropriate to stop, how to do this safely. When your treatment is stopped, it is usually done gradually over a period which is specific to you and may occur over a period of weeks to months. If this medicine is being used for the treatment of epilepsy you must continue to take it as prescribed by your doctor.

2. What you need to know before you take Clobazam Milpharm

Do not take Clobazam Milpharm if:

  • You are allergic (hypersensitive) to

    clobazam, other benzodiazepine medicines or any of the other ingredients of Clobazam Milpharm Tablets (see section 6).

Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.

  • You are pregnant or are planning

    to have a baby (see below under ‘Pregnancy, breast-feeding and fertility’ for more information).

  • 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 liver problems.
    • You have breathing problems.
    • You stop breathing for short

      periods during sleep (called ‘sleep apnoea syndrome’)

    • The patient is under 6 years

      old.

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

Warnings and precautions

Talk to your prescriber before taking this medicine 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 kidney problems.
  • You have ever become dependent

    upon another drug or alcohol. Alcohol should not be taken during treatment with Clobazam Milpharm as there is an increased risk of experiencing side effects.

  • You are over 65. This is due to the

    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. Some patients’ livers 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.

  • You are taking any medicinal or

    non-medicinal products containing cannabidiol, as it may increase the side effects of clobazam.

Your prescriber will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop taking the medicine suddenly as you will be more likely to experience withdrawal symptoms. Your prescriber will ensure that your plan for stopping treatment is tailored to you and can be adapted according to your needs and experience of any withdrawal symptoms.

Benzodiazepines should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of benzodiazepines may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.

Drowsiness, difficulties breathing, coma and death may occur if Clobazam Milpharm is taken together with opioids. Clobazam Milpharm and opioids should only be used concomitantly, when other treatment options are inadequate. Please tell your doctor about all opioid medicines you are taking and follow your doctor’s dosage recommendations closely.

Some studies have shown an increased risk of suicidal ideation, suicide attempt and suicide in patients taking certain sedatives and hypnotics, including this medicine. However, it has not been established whether this is caused by the medicine or if there may be other reasons. If you have suicidal thoughts, contact your doctor as soon as possible for further medical advice (see section 4).

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

Other medicines and Clobazam Milpharm

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because Clobazam Milpharm can affect the way some other medicines work. Also, some medicines can affect the way Clobazam Milpharm 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 (such as Monoamine Oxidase Inhibitors (MAOIs) or tricyclic anti-depressants such as trazodone, or Selective Serotonin Re-uptake Inhibitors (SSRIs) such as fluvoxamine or 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.
  • Omeprazole – used to treat stomach conditions.
  • Ticlopidine – an antiplatelet

    medication used to prevent blood clots.

  • Fluconazole – used in the treatment of fungal conditions.
  • Dextromethorphan – used to relieve dry, irritating coughs.
  • Nebivolol – used to treat high blood pressure.
  • Cannabidiol-containing products

    (medicinal or non-medicinal products).

Concomitant use of clobazam and opioids increases the risk of drowsiness, difficulties breathing, coma and death. Follow your doctor’s dosage recommendations closely.

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

Anaesthetics

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

Clobazam Milpharm with alcohol

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

Pregnancy, breast-feeding and fertility

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 reassess the need for treatment. Do not stop taking Clobazam Milpharm without talking to your doctor.

A large amount of data has not shown evidence for 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.

Talk to your prescriber before taking this medicine if you:

  • are or have ever been addicted to opioids, alcohol, prescription medicines, or illegal drugs, or if you
  • have ever had a history of struggling to control your alcohol or drug intake.
  • have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs.
  • feel you need to take more of

    Clobazam Milpharm to get the same level of symptom control, this may mean you are developing tolerance to the effects of this medicine or are becoming addicted to it. Speak to your prescriber who will discuss your treatment and may change your dose or switch you to an alternative medication.

Taking this medicine regularly, particularly for a long time, can lead to physical dependence and addiction. Your prescriber should have explained how long you will be taking it for and, when it is appropriate to stop, how to do this safely. When your treatment is stopped, it is usually done gradually over a period which is specific to you and may occur over a period of weeks to months.

Physical dependence and addiction can cause withdrawal symptoms when you stop taking this medicine. Withdrawal symptoms can include: headaches, muscle pain, anxiety, tension, depression, restlessness, sweating, confusion or irritability. Do not stop taking your tablets suddenly. This could lead to more serious symptoms such as loss of the sense of reality, feeling unreal or detached from life, and unable to feel emotion. Some patients have also experienced numbness or tingling of the arms or legs, tinnitus (ringing sounds in the ears), oversensitivity to light, sound and touch, uncontrolled or overactive movements, twitching, shaking, feeling sick, being sick, stomach upsets or stomach pain, loss of appetite, agitation, abnormally fast heartbeats, panic attacks, dizziness or feeling that you are about to fall, memory loss, hallucinations, feeling stiff and unable to move easily, feeling very warm, convulsions (sudden uncontrolled shaking or jerking of the body).

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

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

If Clobazam Milpharm 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.

Do not take Clobazam Milpharm if you are breast-feeding or are planning to breast-feed. This is because it may pass into the mothers’ milk.

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.
