Patient leaflet - Clonazepam Dawa 0.5 mg tablets
1. What Clonazepam is and what it is used for
This medicine has been prescribed to treat epilepsy in infants, children and adults.
- It lowers the number of fits (seizures) that you have.
- Any fits that you do have will be less serious.
It contains the active ingredient clonazepam 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. As 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 Clonazepam
Do not take Clonazepam if you are allergic (hypersensitive) to:
clonazepam or to any of the other ingredients of this medicine (listed in
other benzodiazepine medicines. These include diazepam, flurazepam
and temazepam.
Do not take Clonazepam if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking this medicine.
Do not take Clonazepam if you have:
- 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 this medicine.
Warnings and precautions
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, immediately contact your doctor. Talk to your prescriber before taking this medicine if you:
- you have liver, kidney or lung problems
- you have ever had depression
- you have ever tried to harm or kill yourself
- a close friend or relative has recently died
you regularly drink alcohol or use recreational drugs, or you have had
problems with alcohol or drug use in the past. This is because you should not drink alcohol or take recreational drugs while you are taking clonazepam
you have spinal or cerebellar 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. • are or 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.
have previously suffered from withdrawal symptoms such as agitation,
anxiety, shaking or sweating, when you have stopped taking alcohol or drugs.
feel you need to take more of Clonazepam Tablets 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.
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.
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.
Other medicines and Clonazepam
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 (used to treat stomach problems and heartburn) • rifampicin (an antibiotic used to treat infections)
- medicines used 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.
Concomitant use of Clonazepam and opioids (strong pain killers, medicines used for substitution therapy and some cough medicines) increase 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.
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 and alcohol
Do not drink alcohol whilst 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.
Pregnancy and breast-feeding
Do 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.
Driving and using machinery
Talk to your doctor about driving or 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.
Dependence
When taking this medicine there is a risk of dependence. The risk increases with the dose and length of treatment period. The risk is greater if you have ever had a history of alcohol or drug abuse.
Clonazepam contains lactose
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.
