Many people can feel anxious from time to time. Anxiety is normal in stressful situations, and can even be helpful. However, anxiety can become abnormal if it appears for no apparent reason, or if it is out of proportion to a stressful situation, or if it continues after a stressful situation has passed. Oxazepam is an anti-anxiety medicine which is prescribed for short periods of time to help ease the symptoms of anxiety.

Oxazepam works by affecting the way certain substances in your brain (called neurotransmitters) pass messages to your brain cells. It has a calming effect on your brain. The calming effect is helpful in people who have symptoms caused by anxiety, such as difficulties sleeping.

Before taking oxazepam

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 oxazepam it is important that your doctor knows:

  • If you are pregnant or breastfeeding.

  • If you have any breathing problems.

  • If you have any problems with the way your liver works, or if you have any problems with the way your kidneys work.

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

  • If you have ever had a drug or alcohol addiction.

  • If you have a condition causing severe muscle weakness, called myasthenia gravis.

  • If you have ever had an allergic reaction to a medicine.

  • If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

How to take oxazepam

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

  • Take oxazepam exactly as your doctor tells you to. Your doctor will tell you how many tablets to take, and how often to take them. These directions will also be printed on the label of the pack to remind you about what was said to you. As a guide, it is usual to take one or two tablets three times a day for anxiety. If you are taking oxazepam because you are having difficulty sleeping, you may be prescribed a dose to take at bedtime only. The course of treatment prescribed will be as short as possible.

  • Try to take your doses of oxazepam 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 oxazepam 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.

Getting the most from your treatment

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

  • Oxazepam 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 oxazepam could 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.

  • Do not drink alcohol while you are on oxazepam. It will increase the risk of sedative side-effects.

  • Oxazepam 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.

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

  • Your doctor could recommend that you reduce your dose of oxazepam 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.
