• you have ever been addicted to drugs or alcohol
• you have an illness that causes muscle weakness (‘myasthenia gravis’)

• you are in the first 3 months of pregnancy, think you might be pregnant or are breast-feeding (see section 2 ‘Pregnancy, breast-feeding and fertility’)
• the patient is under 2 years old, except if the doctor decides this is necessary.

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

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.

There have been very rare reports of potentially life-threatening skin rashes (Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis) with the use of Perizam. Symptoms of which may include: flu-like symptoms followed by a painful red or purplish rash that spreads and blisters. If you develop any of the above you must stop taking this medicine and inform your doctor straight away (see Section 4).

Talk to your doctor or pharmacist before taking Perizam if:

• you have problems with controlling your movements (‘spinal or cerebellar ataxia’)
• you have depression, irrational fears or obsessions
• you have kidney problems
• you sometimes believe things which are not true (delusions) or see things which are not there (hallucinations)
• you have ever become dependent upon another drug or alcohol. Alcohol should not be taken during treatment with Perizam as there is an increased risk of experiencing side effects
• you are over 65. This is due to increased sensitivity to adverse reactions in elderly such as drowsiness, dizziness and muscle weakness. There is also an increased risk of fall that might result in serious injury
• you have difficulty digesting medicines. In some patients the 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.
• You are taking any medicinal or non-medicinal products containing cannabidiol, as it may increase the side effects of clobazam.

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

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

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 Perizam

You may become dependent on Perizam if you take it for a long period of time, especially if you regularly drink a lot of alcohol or use drugs. This means that you may feel that you need to continue the treatment with Perizam in order to feel well (‘psychological dependence’).

If you suddenly stop taking Perizam you may get:

• worsening of the symptoms you were originally being treated for
• mood changes, feeling anxious, restless, depressed or confused
• sleep problems
• loss of appetite.

These are known as ‘withdrawal symptoms’ and can be avoided by slowly reducing your dose. Talk to your doctor or pharmacist if you are worried about ‘psychological dependence’ or ‘withdrawal symptoms’.

If you take Perizam for epilepsy for a long period of time then it is possible that you may become ‘tolerant’ to it. This means that it will not work as well as it did when you first started taking it. Talk to your doctor if you feel that Perizam is no longer helping to control your symptoms - they may suggest that you take a short break from this medicine.

Epilepsy (fits): Perizam should only be taken by children under 2 years if the doctor decides this is necessary.

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 and herbal medicines. This is because Perizam can affect the way some other medicines work.

Also, some other medicines can affect the way Perizam works.

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

• medicines for epilepsy such as phenytoin, carbamazepine or valproic acid
• medicines for depression such as trazodone, ‘SSRI’s’ (such as fluoxetine or citalopram), ‘tricyclic antidepressants’ (such as amitriptyline or nortriptyline) or ‘MAOIs’ (such as phenelzine or moclobemide)
• medicines for serious mental health problems called ‘neuroleptics’ such as chlorpromazine, haloperidol, clozapine and pimazide
• painkillers such as medicines containing codeine, dihydrocodeine or morphine
• sleeping tablets such as zolpidem or temazepam
• medicines for anxiety such as diazepam or lorazepam
• muscle relaxants such as baclofen
• antihistamines that make you feel sleepy such as chlorphenamine, promethazine or diphenhydramine
• lithium, used for a serious mental health problem called ‘bipolar disorder’ (mood changes between a state of high excitability or exaggerated emotions and depression)
• cimetidine, used to treat stomach ulcers and heartburn
• omeprazole, used to treat 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, medicines used to treat high blood pressure.
• Cannabidiol-containing products (medicinal or non-medicinal products)

When taking Perizam you should not start taking any different medicines containing clobazam unless your doctor tells you to. If you do, it may cause breathing difficulties and sleepiness.

Concomitant use of Perizam and opioids increases the risk of drowsiness, difficulties breathing, coma and death. Because of this, concomitant use should only be considered when other treatment options are not possible.

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 operation or dental work, tell your doctor or dentist that you are taking Perizam. This is because they may need to change the amount of medicine (anaesthetic or muscle relaxant) they give to you.

Do not drink alcohol while taking Perizam. This is because alcohol can change the way Perizam works.

Do not take Perizam if:

• you are in the first 3 months of pregnancy or think you may be pregnant
• you are breast-feeding. This is because Perizam may pass into the mother’s breast milk.

Talk to your doctor before taking this medicine if you are more than 3 months pregnant or plan to become pregnant.

• Your doctor may give you this medicine during later pregnancy or during labour. If this happens, there is a risk of having a baby with low body temperature, floppiness, breathing or feeding problems.
• If this medicine is taken regularly in late pregnancy, your baby may get withdrawal symptoms. In this case the newborn should be closely monitored during the postnatal period.

In fertility studies, no effects on fertility were observed in animals.

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 feel 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
  • You have taken it according to the instructions given by the prescriber or in the information provided with the medicine
  • 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.

• Take the syringe and put it in the adaptor opening (Figure 3).
• Turn the bottle upside down (Figure 4).

• Fill the syringe with a small amount of solution by pulling the piston down (Figure 4A). Then push the piston upward in order to remove any possible bubbles (Figure 4B). Finally, pull the piston down to the graduation mark corresponding to the quantity in millilitres (ml) prescribed by your doctor (Figure 4C).

• Turn the bottle the right way up (Figure 5A).
• Remove the syringe from the adaptor (Figure 5B). Put the end of the syringe into your mouth and push the plunger slowly back in to take the medicine.
• Wash the syringe with water and let it dry before you use it again (Figure 6).
• Close the bottle with the plastic screw cap - leave the syringe adaptor in the bottle.
