זמין כ

Tablets, oral liquid medicine and injection

Lorazepam works by affecting the way certain substances in your brain (called neurotransmitters) pass messages to your brain cells. It has a calming effect on various functions of your brain.

The calming effect is helpful in a variety of conditions which can be caused by חרדה, such as panic attacks and difficulties sleeping. The calming effect is also used to relax and/or sedate people who are having certain medical investigations or treatments. It is given as a pre-med, particularly during procedures that can cause anxiety or discomfort. The calming action also helps to relax muscles, so lorazepam injection is used to treat fits, such as those caused by epilepsy.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking lorazepam it is important that your doctor knows:

  • אם את בהריון או מניקה.

  • אם יש לך בעיות נשימה.

  • אם יש לך בעיות בתפקוד הכבד שלך, או אם יש לך בעיות בתפקוד הכליות שלך.

  • If you have a mental health problem. This includes conditions such as psychosis, depression, obsessive conditions, phobias and personality disorders.

  • אם אי פעם הייתה לך התמכרות לסמים או לאלכוהול.

  • אם יש לך מצב הגורם לחולשת שרירים חמורה, הנקרא מיאסטניה גרביס.

  • אם אי פעם הייתה לך תגובה אלרגית לתרופה.

  • אם אתה נוטל או משתמש בתרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about lorazepam, and will also provide you with a full list of the side-effects which you could experience from taking it.

  • Take lorazepam exactly as your doctor tells you to - the dose will be individualised to suit your needs. The directions for taking the tablets will be printed on the label of the pack to remind you about what the doctor said to you. You could be asked to take just one single dose (if it is before a medical procedure, for example), or to take regular doses for a short while. If you are to take lorazepam regularly for anxiety, you will probably be prescribed two or three doses to take a day. If you are taking it because you are having difficulty sleeping, you will be prescribed a dose to take at bedtime only. The course of treatment prescribed will be as short as possible. If you have any questions about how to take the tablets, please ask your doctor or pharmacist for further advice.

  • Try to take your doses of lorazepam at the same times of day each day, as this will help you to remember to take them. Swallow the tablet(s) with a drink of water. You can take lorazepam either with or without food.

  • If you forget to take a dose at the usual time, take it when you remember. Try to take the correct number of doses each day, but do not take two doses together to make up for a forgotten dose.

  • Remember to keep any follow-up appointments with your doctor. This is so your doctor can check on your progress.

  • Lorazepam is likely to affect your reactions and ability to drive. It is an offence to drive while your reactions are impaired. Do not drive until you know how you react, especially when you first start treatment. Please also be aware that the effects of lorazepam can last into the following day. Even if your driving ability is not impaired, should you drive, you are advised to carry with you some evidence that the medicine has been prescribed for you - a repeat prescription form or a patient information leaflet from the pack is generally considered suitable.

  • You should not drink alcohol while you are on lorazepam. It will increase the risk of sedative side-effects.

  • Lorazepam is taken for short periods of time only, often for just a few days. It will not be for longer than four weeks, as this may lead to you feeling dependent on it. Also, your body gets used to it quickly, and after this time it is unlikely to have the same effect.

  • It is possible that drinking grapefruit juice can increase the amount of lorazepam in your bloodstream, which may increase the risk of side-effects. It is probably best to avoid drinking grapefruit juice while you are taking lorazepam.

  • If you are due to have an operation or any dental treatment, please tell the person carrying out the treatment that you are taking lorazepam. This is because lorazepam increases the effects of some anaesthetics.

  • Your doctor could recommend that you reduce your dose of lorazepam gradually when it is time to stop taking it. This is to reduce the risk of you experiencing withdrawal effects. Follow carefully any instructions your doctor gives to you.
