• Clonazepam or any of the other ingredients of this medicine (listed in Section 6).
• Other benzodiazepine medicines, such as diazepam, flurazepam and temazepam.

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 Clonazepam.

• Breathing problems or lung disease.
• Severe liver problems.
• A condition called ‘myasthenia gravis’ (where your muscles become weak and get tired easily).
• A condition called ‘sleep apnoea syndrome’ (where your breathing stops when you are asleep).
• Problems with alcohol or drug (prescription or recreational) use.

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 Clonazepam.

Talk to your doctor or pharmacist before taking Clonazepam.

A small number of people being treated with anti-epileptics such as clonazepam have had thoughts of harming or killing themselves. If at any time you have these thoughts, contact your doctor immediately.

Check with your doctor or pharmacist before taking Clonazepam if:

• You have liver, kidney or lung problems.
• You have ever had depression.
• You have ever tried to kill yourself.
• A close friend or relative has recently died.
• You regularly drink alcohol or take recreational drugs or you have had problems with alcohol or drug use in the past.
• You have ataxia (where you may become shaky and unsteady, have slurred speech or rapid eye movements).
• You have a rare, inherited blood condition called ‘porphyria’.
• You are elderly or debilitated (weak); your doctor may adjust your dose.

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

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines that you buy without a prescription and herbal medicines. This is because clonazepam can affect the way some other medicines work.

Also some other medicines can affect the way clonazepam works.

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

• Other medicines to treat epilepsy, such as carbamazepine, lamotrigine, hydantoins, phenobarbital, phenytoin, primidone or sodium valproate.
• Cimetidine (used to treat stomach problems and heartburn).
• Rifampicin (an antibiotic used to treat infections).
• Medicines used to make you sleep (hypnotics).
• Medicines that help with anxiety (tranquillisers).
• Pain-killers (analgesics) and medicines to relax your muscles (muscle relaxants).

Concomitant use of Clonazepam and opioids (strong pain killers, medicines for substitution therapy and some cough medicines) increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.

However if your doctor does prescribe Clonazepam together with opioids the dose and duration of concomitant treatment should be limited by your doctor.

Please tell your doctor about all opioid medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.

If you are going to have an anaesthetic for an operation or for dental treatment, it is important to tell your doctor or dentist that you are taking Clonazepam.

Do not drink alcohol while you are taking Clonazepam. This is because it may cause side effects or cause your fits to return. Alcohol can also increase the effects of Clonazepam, possibly leading to severe sedation that could result in coma or death.

You must not take Clonazepam if you are pregnant, might become pregnant or are breast-feeding, unless your doctor tells you to. Clonazepam is known to have harmful effects on the unborn child.

Talk to your doctor about driving and using machines or tools, whilst you are taking Clonazepam. This is because it can slow down your reactions, particularly when you start taking it. If you are in any doubt about whether you can do a particular activity, talk to your doctor.

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.

When taking this medicine there is a risk of dependence which increases with the dose and duration of treatment and also in patients with a history of alcohol and/or drug abuse.

This medicine contains 64.68mg of alcohol (ethanol) in each 5 ml which is equivalent to 64.68mg of ethanol (96%) per 5ml dose. The amount in 5ml of this medicine is equivalent to less than 2 ml beer or 1 ml wine.

The small amount of alcohol in this medicine will not have any noticeable effects.

Clonazepam Thame 0.5mg/5ml Oral

Solution is recommended for starting dose.

Adults: The usual starting dose is 10ml (1mg) a day, or less.

Elderly: The usual starting dose is 5ml (0.5mg) a day, or less.

Clonazepam Thame 2mg/5ml Oral Solution is recommended for maintenance dose.

Adults and elderly: The starting dose will be increased gradually as maintenance dose (usually to between 10ml (4mg) and 20ml (8mg) a day). The maximum dose is 50ml (20mg) a day.

This medicine must be taken orally. Use the 10ml oral syringe with 1ml measurement markings (0.25ml intermediate graduation) provided in the pack.

a) Open the bottle: press the cap and turn it anticlockwise.
b) Separate the adaptor from the syringe. Insert the adaptor into the bottle neck. Ensure it is properly fixed. Take the syringe and put it in the adaptor opening.

c) Turn the bottle upside down. Fill the syringe with a small amount of solution by pulling the piston down, then push the piston upwards in order to remove any possible bubble. Pull the piston down to the graduation mark corresponding to the quantity in milliliters (ml) prescribed by your doctor.

d) Turn the bottle the right way up. Remove the syringe from the adaptor.

e) Empty the contents of the syringe into the patient’s mouth by pushing the piston to the bottom of the syringe. The contents of the syringe should be emptied into the side cheek of the patient's mouth to avoid a choking hazard. Close the bottle with the plastic screw cap. Wash the syringe with water.

• If you take more Clonazepam than you should, talk to a doctor or go to a hospital straight away. Take the medicine pack with you.
• If you take more Clonazepam, you may feel drowsy, sleepy, light-headed, have a lack of co-ordination or be less responsive than normal.

• If you forget to take a dose, skip the missed dose. Then take the next dose when it is due.
• Do not take a double dose (two doses at the same time) to make up for a forgotten dose.

If you receive long term treatment with Clonazepam (are given the medicine for a long time) you may become dependent upon this medicine and get withdrawal symptoms (see Section 4).

• Do not stop taking your medicine without talking to your doctor. If you do, your fits may return and you may get withdrawal symptoms (see Section 4).
• If the dose of Clonazepam you take has to be reduced, or stopped, this must be done gradually. Your doctor will let you know how to do this.

If someone else takes your Clonazepam by mistake, they should talk to a doctor or go to a hospital straight away.
