1. What Clonazepam Celix Tablets are and what are they used for

The name of your medicine is clonazepam (called Clonazepam Celix Tablets in this leaflet). Clonazepam belongs to a group of medicines called ‘benzodiazepines. It is used to treat epilepsy. Clonazepam Celix Tablets work by preventing seizures or fits. Any fits that you do have will be less serious.

2. What you need to know before you take Clonazepam Celix Tablets
Do not take Clonazepam Celix Tablets:
  • if you are allergic to clonazepam or any of the other ingredients of this medicine (listed in section 6)
  • if you are allergic to other benzodiazepine medicines. These include diazepam, chlordiazepoxide, bromazepam, temazepam and flurazepam
  • if you have lung disease or breathing problems
  • if you have myasthenia gravis (severe muscle weakness)
  • if you suffer from sleeping disorders, such as difficulty breathing while asleep (sleep apnoea)
  • if you have a severe liver condition
  • if you have problems with alcohol or drug (prescription or recreational) use

If you are not sure, talk to your doctor or pharmacist before taking this medicine.

Warnings and precautions

Talk to your doctor or pharmacist before taking Clonazepam Celix Tablets if: -

  • you have a lung, liver or kidney condition
  • you have a history of depression or have attempted suicide or tried to harm yourself
  • you have recently suffered a death of a close friend or relative
  • you regularly drink alcohol or use recreational drugs
  • you have porphyria (a disease that affects the skin and/or nervous system)
  • you suffer from cerebellar ataxia (you have a problem co-ordinating movement)
  • you are elderly or debilitated (weak); your doctor may adjust your dose

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.

Other medicines and Clonazepam Celix Tablets

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, including 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, hydantoins, phenobarbital, phenytoin, primidone or sodium valproate
  • cimetidine (medicine used to treat stomach problems)
  • rifampicin (an antibiotic)
  • anaesthetics
  • medicines to make you sleep (hypnotics), or that make you feel sleepy as a side effect.
  • medicines that help with anxiety (tranquillisers)
  • pain killers (analgesics) or medicines to relax your muscles (muscle relaxants)
  • medicines that reduce your blood pressure, such as ramipril, candesartan, amlodipine, doxazosin

If any of the above applies to you (or you are not sure), talk to your doctor or pharmacist before taking Clonazepam Celix Tablets.

Using Clonazepam Celix Tablets and opiods (strong painkillers, medicines used for substitution therapy and some cough medicines) or together with sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, using these medicines together should only be considered when other treatment options are not possible.

However if your doctor does prescribe Clonazepam Celix Tablets together with opiod or sedative medicines, the dose and duration of this treatment should be limited by your doctor.

Please tell your doctor about all opiod or sedative 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.

Operations

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.

Clonazepam Celix Tablets with alcohol

Do not drink alcohol whilst taking Clonazepam Celix Tablets as it may cause fits (epileptic seizures) and increase the risk of having side effects. Alcohol can also increase the effects of clonazepam, possibly leading to severe sedation that could result in coma or death.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Clonazepam is known to have harmful effects on the unborn child.

Driving and using machines

Clonazepam may affect your ability to drive, operate machinery and other hazardous activities, particularly in the first few days of treatment. This may be made worse if you drink alcohol.

Increasing the dose of clonazepam or changing the time that you take it may also slow your reactions. You should not drive unless your doctor says you can.

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 accordance with 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.

Dependence

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.

Clonazepam Celix Tablets contain lactose

This medicine contains lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

3. How to take Clonazepam Celix Tablets

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

If you take more Clonazepam Celix Tablets than you should

If you take too many tablets or someone else accidentally takes your medicine, contact you doctor, pharmacist or go to your nearest hospital immediately. Take the medicine pack with you.

If you take too much clonazepam you may feel drowsy, sleepy, light-headed, have a lack of coordination or be less responsive than normal.

If you forget to take Clonazepam Celix Tablets

If you forget to take a dose, skip the missed dose and simply 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 stop taking Clonazepam Celix Tablets

Do not suddenly stop taking Clonazepam Celix Tablets. If you need to stop taking Clonazepam Celix Tablets, your doctor will tell you how to stop slowly to reduce any side effects as you can get withdrawal symptoms if you stop suddenly. These symptoms may include problems with sleeping, upset stomach/diarrohoea, muscle pain, anxiety (sometimes severe), tension, restlessness, confusion, severe mood changes, irritability, sweating, shakes (tremor), headaches, hallucination, faster heart beat and agitation. In serious cases, withdrawal effects can also include being oversensitive to light, noise and touch, hallucinations, tingling, numbness and a feeling of being unreal.
