Patient leaflet - Perizam 2 mg / ml oral suspension
1.What Perizam Oral Suspension is and what it is used for
The full name of your medicine is Perizam 2mg/ml Oral Suspension. In this leaflet the shorter name Perizam is used. It contains the active ingredient Clobazam.
This medicine has been prescribed for you for either:
- symptomatic treatment of severe anxiety (short term use only)
- epilepsy (fits) in adults and children over 2 (together with other treatments)
- mental illness such as schizophrenia (together 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 Perizam Oral Suspension

Warnings and precautions
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 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. Alcohol should not be taken during treatment with Perizam as there is an increased risk of experiencing side effects
- you have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs
- 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.
- you feel you need to take more of Perizam 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.
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. Suicidal thoughts
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).

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’).
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).
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.
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.
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.
Children under 2 years
Epilepsy (fits): Perizam should only be taken by children under 2 years if the doctor decides this is necessary. Other medicines and Perizam
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 anti-depressants’ (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.
Operations
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. Perizam with alcohol
Do not drink alcohol while taking Perizam. This is because alcohol can change the way Perizam works. Pregnancy, breast-feeding and fertility
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.
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 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.

doctor before taking this medicine.
Sodium methyl parahydroxybenzoate and sodium propyl parahydroxybenzoate. These may cause an allergic reaction.
This allergy may happen some time after starting the medicine.

0.12% of the recommended maximum daily dietary intake of sodium for an adult. This should be taken into account by patients on a low salt diet.
This medicine contains 6.21mg propylene glycol in each ml. If your baby is less than 4 weeks old, talk to your doctor or
pharmacist before giving them this medicine, in particular if the baby is given other medicines that contain propylene glycol or alcohol.
