1. WHAT LORAZEPAM TABLETS IS AND WHAT IT IS USED FOR

The name of your medicine is Lorazepam Tablets. It contains lorazepam, which belongs to a class of medicines called benzodiazepines. It can help to relieve anxiety. This medicine has been prescribed for you as short-term therapy for anxiety (2-4 weeks), or sleeping difficulties due to anxiety. It may also be used as a sedative before surgery or operative dental treatment. Lorazepam Tablets are not to be used for longer than 4 weeks, to treat mild or moderate anxiety in adults or for anxiety/insomnia in children.

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.

Lorazepam may cause muscle relaxation and caution is advised as you may be at a greater risk of falling (see section 4). 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.

Taking other medicines

Tell your doctor or pharmacist that you are taking lorazepam before taking any other medicine or if you enter hospital for treatment, or if you are taking any other medicines, including those which have not been prescribed by a doctor, since they may affect the way Lorazepam Tablets work.

Lorazepam Tablets may also affect the way other drugs work. In particular, you should tell your doctor if you are taking any other sedative (e.g. barbiturates or antihistamines), anti-anxiety drugs, anti-depressants, strong pain killers (e.g. methadone), drugs for epilepsy (e.g. phenobarbital or valproate), antihistamines, or drugs for mood or mental disorders (e.g. chlorpromazine, loxapine or clozapine), drugs for cataplexy; treating HIV; to treat delusions or hallucinations; to help with indigestion (e.g. omeprazole); muscle relaxants (e.g. baclofen and tizanidine); drugs for addiction treatment (e.g. lofexidine and disulfiram); TB drugs such as isoniazid; antibiotics such as erythromycin; drugs to treat high blood pressure; Parkinson’s disease drugs e.g. levodopa; oestrogen-containing contraceptives and drugs for asthma (theophylline). The dose of these drugs may need to be reduced before you can take lorazepam.

Concomitant use of this product 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 this product 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. Using Lorazepam with food or drink

Grapefruit juice and drinks containing caffeine should be avoided as they can affect the way that Lorazepam Tablets work. Pregnancy and breast-feeding

If you take this medicine during late pregnancy or during labour, your baby, when born, may be less active than other babies, have a low body temperature, be floppy, or have breathing or feeding difficulties for a while. Your baby’s response to the cold might be temporarily impaired. If this medicine is taken regularly in late pregnancy, your baby may develop withdrawal symptoms after birth.

Do not take this medicine if you are breast-feeding, since the drug may pass into breast milk, and cause the baby to be less active and unable to suckle.

Driving and using machines

Lorazepam may make you feel dizzy, sleepy or forgetful during the day, or may affect your concentration. This may affect your performance at skilled tasks such as driving machinery or operating machinery by affecting your vision or muscle function. You should not take part in any other activities where this could put yourself or others at risk. You should avoid alcohol while you are taking lorazepam, since this may make you very drowsy and seriously affect your ability to drive or use machines.

3. HOW TO TAKE LORAZEPAM TABLETS

Always take this medicine exactly as your doctor has told you. The label on your medicine should also tell you. Check with your doctor or pharmacist if you are not sure. Lorazepam Tablets should be swallowed with water.

Your prescriber should have discussed with you how long the course of tablets will last. They will arrange a plan for stopping treatment. This will outline how to gradually reduce the dose and stop taking the medicine. 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.

Adults (and children over 13 years of age)

  • Anxiety: 1 to 4 mg daily in divided doses. Your doctor will tell you how often to take your tablets.
  • Sleeping problems: 1 to 2 mg before going to sleep. You should make sure that you will be able to sleep for 7 to 8 hours before taking your tablets.
  • Before surgery: 2 to 3 mg the night before your operation and 2 to 4 mg 1 or 2 hours before your operation.

Children (between 5 and 13 years of age)

  • Before surgery: the dose is usually between 0.5 and 2.5mg (depending on your child’s weight) at least 1 hour before your child’s operation.
  • Lorazepam is not recommended for the treatment of anxiety or sleeping problems in children. Nor is it recommended for children below 5 years of age.

Elderly or patients with liver or kidney problems

  • Older patients may be given lower doses. They may respond to half the usual adult dose or less.

Lorazepam is usually prescribed for short courses of treatment, lasting from a few days to 4 weeks including a dose reduction at the end. This reduces the risk of becoming dependent on Lorazepam Tablets, or suffering unpleasant effects when you stop taking them. (See ‘If you stop taking Lorazepam Tablets’ section). The beneficial effect of Lorazepam Tablets may be less apparent after several weeks of use. If you are given lorazepam for more than 4 weeks, your doctor might want to take blood samples occasionally to check your blood and liver, since drugs like lorazepam have occasionally affected blood and liver function. If you take more Lorazepam Tablets than you should

If anyone has taken an overdose of Lorazepam Tablets (that is more than the doctor has prescribed), seek medical help immediately, either by calling your doctor, or going to the nearest casualty department. Always take the labelled medicine container with you, even if there are no tablets left.

If you forget to take Lorazepam Tablets

Do not take a double dose to make up for a forgotten tablet. If you forget to take a tablet for anxiety, you should take it as soon as you remember if it is less than 3 hours since your usual time. If more than 3 hours has passed from when you usually take your tablet, just take your next tablet when it is due. If you forget to take a tablet for sleeping problems, only take it if you will be able to sleep for 7 to 8 hours afterwards.

If you stop taking Lorazepam Tablets

  • After you have finished your prescribed treatment with lorazepam, your doctor will decide if you need further treatment.
  • The number of Lorazepam Tablets and how often you take them should always be reduced slowly before stopping them. This allows your body to get used to being without your tablets, and reduces the risk of unpleasant effects when you stop taking them. Your doctor will tell you how to do this.
  • On stopping lorazepam, you may experience symptoms such as headaches, muscle pain, anxiety, tension, depression, restlessness, sweating, confusion or irritability. Your original sleeplessness may also return. If you suffer from any of these symptoms, ask your doctor for advice.
  • Do not suddenly stop taking this medicine. If you want to stop taking this medicine, discuss this with your prescriber first. They will tell you how to do this, usually by reducing the dose gradually so that any unpleasant withdrawal effects are kept to a minimum. This may occur over a period of weeks to months. 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.

Withdrawal symptoms such as:

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).

  • Patients taking anti-depressants and patients with seizure disorders may be more likely to experience convulsions. If you suffer from any of these symptoms, ask your doctor for advice immediately.
