Frisium contains a medicine called clobazam. This belongs to a group of medicines called benzodiazepines. It works by having a calming effect on the brain.

Frisium can be used for:

  • Severe anxiety over a short time
  • Epilepsy (fits) over a longer time
  • Mental illness such as schizophrenia (in combination with other treatments)

Do not take Frisium if:
  • You are allergic (hypersensitive) to clobazam, other benzodiazepine medicines or any of the other ingredients of Frisium (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, breastfeeding 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 Frisium.

Warnings and precautions

Talk to your doctor or pharmacist before taking Frisium 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 Frisium 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 nonmedicinal products containing cannabidiol, as it may increase the side effects of clobazam.

Drowsiness, difficulties breathing, coma and death may occur if Frisium is taken together with opioids. Frisium 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 Frisium.

Other medicines and Frisium

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 Frisium can affect the way some other medicines work. Also, some medicines can affect the way Frisium 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 diphenenhydramine).
  • 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 Frisium 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.


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

Frisium with alcohol

Do not drink alcohol while taking Frisium. 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 Frisium 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.

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 clobazam during the second and/or third trimester of pregnancy.

If Frisium 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 Frisium if you are breast-feeding or are planning to breast-feed. This is because it may pass into the mothers’ milk.

Driving and using 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.
