1. Why am I using Frisium?

Frisium contains the active ingredient clobazam. Frisium belongs to a group of medicines called benzodiazepines. They are thought to work by their action on brain chemicals.

In general, benzodiazepines such as Frisium should be taken for short periods only (up to one month). Continuous long term use is not recommended unless advised by your doctor. The prolonged use of benzodiazepines may lead to dependence on the medicine.


Frisium is used to treat anxiety and sleep disturbances associated with anxiety. Anxiety or tension associated with the normal stress of everyday life usually does not require treatment with medicines.


Frisium is used along with other medicines to treat partial refractory and Lennox-Gastaut epilepsy (fits) in children 4 years of age or older.

Your doctor, however, may prescribe Frisium for another purpose.

Ask your doctor if you have any questions about why it has been prescribed for you.

This medicine is available only with a doctor’s prescription.

2. What should I know before I use Frisium?


Do not use Frisium if:

  • you are allergic to clobazam, or any of the ingredients listed at the end of this leaflet.
    Always check the ingredients to make sure you can use this medicine.
  • you have severe or chronic lung disease
  • you have a history of drug or alcohol abuse
  • you have severe muscle weakness known as myasthenia gravis
  • you have sleep apnoea syndrome where you snore heavily and stop breathing during the night
  • you have severely reduced liver function.

Some symptoms of an allergic reaction include skin rash, itching, shortness of breath or swelling of the face, lips or tongue, which may cause difficulty in swallowing or breathing.

Do not give Frisium to a child or adolescent for the treatment of anxiety or sleep disorders.

Tell your doctor if you have or have had any other medical conditions, especially the following:

  • liver, kidney or lung disease
  • fits or convulsions (epilepsy)
  • low blood pressure
  • pre-existing muscle weakness
  • ataxia (unsteadiness when walking)
  • addiction to drugs or medicines
  • glaucoma (high pressure in the eye)
  • depression, psychosis or schizophrenia
  • if you drink alcohol regularly
  • Your tolerance to alcohol will be reduced and it will increase the effect of Frisium.
  • Alcohol should be avoided during Frisium use.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Do not give Frisium to a child or adolescent for the treatment of anxiety or sleep disorders.

Pregnancy and breastfeeding

Do not take Frisium if you are pregnant or if you intend to become pregnant.

Benzodiazepines including Frisium cross the placenta and may cause reduced muscle strength, breathing difficulties, hypothermia (a drop in body temperature) and feeding difficulties (signs and symptoms of so-called “floppy infant syndrome”) in the newborn infant with potentially fatal effects.

Do not take it if you are breast-feeding or planning to breast-feed.

Frisium passes into the breast milk and may cause drowsiness and/or feeding difficulties in the infant. It is not recommended for use while breast-feeding.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with the absorption of Frisium and affect how it works.

  • other sleeping tablets, sedatives or tranquillisers
  • benzodiazepines (medicines used as sedatives or to treat anxiety)
  • anticholinergics (medicines used to relieve stomach cramps or spasms, to prevent travel sickness and to treat Parkinson’s disease)
  • alcohol, (ethanol), contained in some medicines eg cough syrups
  • medicines used to treat reflux or upset stomach, such as omeprazole
  • medicines for depression
  • medicines for allergies, for example antihistamines or cold tablets
  • pain relievers, such as opioids or narcotic analgesics muscle relaxants
  • dietary supplements and recreational products
  • medicines to control fits (including marijuana).

These medicines may be affected by Frisium, or they may affect how well it works. You may need to take different amounts of your medicine or take different medicines.

The use of Frisium together with opioids increases the risk of drowsiness, difficulties breathing, coma and death.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Frisium.

4. How do I use Frisium?

How much to take

  • The dose of Frisium may be different for each person. Your doctor will decide the right dose for you.
  • Ask your doctor if you are unsure of the correct dose for you.
  • Follow the instructions provided and use Frisium until your doctor tells you to stop.
  • If you take the wrong dose, Frisium may not work as well and your problem may not improve.
  • Swallow the prescribed dose of Frisium tablet(s) with a full glass of water.
  • Frisium tablets can be halved if a lower dose is recommended by your doctor.

When to take Frisium

  • Take Frisium at about the same time each day preferably in the evening.
  • Taking tablets at the same time each day will have the best effects. It will also help you remember when to take the tablets.
  • If you are not sure when to take it, ask your doctor.

How long to take Frisium

  • Do not use Frisium for longer than your doctor has advised.
  • Ask your doctor if you are not sure how long to take the medicine for.

If you forget to use Frisium

Frisium should be used regularly at the same time each day. If you miss your dose at the usual time.

Do not try to make up for missed doses by taking more than one dose at a time.

This may increase the chance of getting an unwanted side effect.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose you missed.

If there is still a long time to go before your next dose, take it as soon as you remember, and then go back to taking it as you would normally.

If you are not sure what to do, ask your doctor.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you use too much Frisium

If you think that you have used too much Frisium, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

Also report any other medicine or alcohol which has been taken. You may need urgent medical attention.

If you take too much Frisium you will probably feel drowsy, confused, tired, dizzy, have difficulty breathing, feel weak or become unconscious.

  • Do not suddenly stop taking Frisium if you suffer from epilepsy.
  • Stopping this medicine suddenly may make your epilepsy worse.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how Frisium affects you.

Frisium may cause drowsiness or dizziness in some people and therefore may affect alertness.

Make sure you know how you react to Frisium before you drive a car, operate machinery, or do anything else that could be dangerous if you are drowsy, dizzy or not alert.

Even if you take Frisium at night, you may still be drowsy or dizzy the next day.

Drinking alcohol

Tell your doctor if you drink alcohol.

Your tolerance to alcohol will be reduced and it will increase the effect of Frisium.

Alcohol should be avoided during Frisium use.

Dependence and withdrawal

Frisium should only be used for short periods of time (2 to 4 weeks).

The use of benzodiazepines may lead to physical and psychological dependence and withdrawal syndrome when you stop taking the medicine.

If you stop taking Frisium suddenly you may experience the following withdrawal effects:

  • depression
  • nervousness
  • difficulty in sleeping
  • irritability
  • sweating
  • upset stomach/diarrhoea
  • or the symptoms you are being treated for can come back worse than before

You may also experience mood changes, anxiety, restlessness and changes in sleep patterns. These effects may occur even after taking low doses for a short period of time. If you stop taking this medicine suddenly you may experience confusion, hallucinations, shaking, faster heartbeat or fits. Withdrawal may also cause unusual behaviour including aggressive outbursts, excitement or depression with suicidal thoughts or actions.

Looking after your medicine

  • Keep your tablets in their blister pack until it is time to take them.
  • If you take the tablets out of the blister pack they may not keep as well.
  • Keep the medicine in a cool dry place where the temperature stays below 30°C.
  • Follow the instructions in the carton on how to take care of your medicine properly.

Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Keep it where young children cannot reach it.

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Getting rid of any unused medicine

If your doctor tells you to stop taking Frisium or the tablets have passed their expiry date, ask your pharmacist what to do with any that are left over.

If you no longer need to use this medicine or it is out of date, take it to any pharmacy for safe disposal.

Do not use this medicine after the expiry date.
