What Noumed Diazepam is used for

Diazepam has sedative and muscle relaxant effects and is used to:

  • treat anxiety (anxiety or tension associated with the normal stress of everyday life which usually does not require treatment with medicines)
  • relax muscles
  • treat symptoms such as trembling, confusion and anxiety associated with alcohol withdrawal
  • treat panic attacks

Diazepam belongs to a group of medicines called benzodiazepines.

These medicines are thought to work by their action on brain chemicals.

Benzodiazepines are not recommended as the only treatment of severe mental illnesses and should not be used alone to treat depression.

Your doctor, however, may have prescribed it for another purpose.

Ask your doctor if you have any questions about why diazepam has been prescribed for you.

In general, benzodiazepines such as Noumed Diazepam should be taken for short periods only (around 2 to 4 weeks). Continuous long-term use is not recommended unless advised by your doctor.

The use of benzodiazepines may lead to dependence on the medicine.

This medicine is available only with a doctor’s prescription.

How to take Noumed Diazepam

How much to take

Take Noumed Diazepam exactly as your doctor has prescribed.

Your doctor will tell you how many Noumed Diazepam tablets to take each day.

The dose of diazepam varies from person to person depending on age and the condition being treated. The usual adult dose is between 5 and 40 mg daily. Children, elderly and very ill patients may need to take less.

How to take it

Swallow Noumed Diazepam tablets with a full glass of water.

When to take it

Diazepam can be taken up to three times a day. Your doctor will tell you how much you need to take. The tablets can be taken with or without food.

How long to take it

Usually, diazepam should be taken for short periods only (for example, for 2 to 4 weeks). Continuous long-term use is not recommended unless advised by your doctor. The use of benzodiazepines may lead to dependence on the medicine.

Continue taking Noumed Diazepam until your doctor tells you to stop.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much diazepam.

Do this even if there are no signs of discomfort or poisoning.

Also report any other medicine or alcohol which has been taken.

You may need urgent medical attention.

If you have taken too much diazepam, you may feel drowsy, confused, dizzy, have difficulty breathing, feel weak or become unconscious. It is important that you recognise these signs of overdose early.

If you are not sure what to do, contact your doctor or pharmacist.

While you are taking Noumed Diazepam

Things you must do

Tell all doctors, dentists and pharmacists who are treating you that you are taking diazepam.

Do not take any other medicines whether they require a prescription or not without first telling your doctor.

If you become pregnant while you are taking Noumed Diazepam, tell your doctor immediately.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.

Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise your doctor may think that it was not effective and change your treatment unnecessarily.

Tell your doctor if you feel the tablets are not helping your condition.

Be sure to keep all of your appointments with your doctor so that your progress can be checked.

Always discuss with your doctor any problems or difficulties during or after taking Noumed Diazepam.

Things you must not do

Do not drive or operate machinery until you know how diazepam affects you. Diazepam may cause drowsiness or dizziness in some people and therefore may affect alertness. Make sure you know how you react to diazepam before you drive a car or operate machinery or do anything else that could be dangerous if you are drowsy, dizzy or not alert. Even if you take this medicine at night, you may still be drowsy or dizzy the next day.

Do not take diazepam for a longer time than your doctor has prescribed.

Diazepam should be taken for short periods only (for example, 2 to 4 weeks), unless advised by your doctor.

Do not stop taking your medicine or lower the dose, without first checking with your doctor. Stopping this medicine suddenly may cause some unwanted effects. Your doctor may decide to slowly reduce your dose of diazepam before you can stop taking it completely.

Do not let yourself run out of medicine on weekends or holidays.

Do not suddenly stop taking diazepam if you suffer from epilepsy. Stopping this medicine suddenly may make your epilepsy worse.

Do not take Noumed Diazepam to treat any other complaints unless your doctor tells you to.

Do not give your medicine to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful if you are elderly, unwell, drinking alcohol or taking other medicines.. Your doctor may suggest that you avoid alcohol or reduce the amount of alcohol you drink while you are taking Noumed Diazepam.

Some people may experience side effects such as drowsiness, confusion, dizziness and unsteadiness, which may increase the risk of a fall.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Noumed Diazepam.

This medicine helps most people with anxiety but it may have unwanted side effects in a few people. All medicines may have side effects. Sometimes they are serious, most of the time they are not. Some side effects may require medical treatment.

If you are elderly, unwell or taking other medicines, you may have an increased chance of getting side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • drowsiness, tiredness
  • dizziness, unsteadiness
  • loss of memory, inattentiveness, confusion, lack of concentration
  • headache, hangover feeling in the morning
  • slurred speech
  • unpleasant dreams

The above list includes the more common side effects of diazepam. They are usually mild and may disappear if the dose is reduced.

Tell your doctor immediately or go to casualty at your nearest hospital if you notice any of the following:

  • sudden anxiety or excitation
  • restlessness, agitation, irritability, anger, abnormal behaviour
  • hallucinations or delusions
  • severe sleep disturbances
  • difficulties in breathing or choking or coughing

These are serious side effects. You may need medical attention. Serious side effects are rare.

This is not a complete list of all possible side effects. Others may occur in some people and there may be some side effects not yet known.

Tell your doctor if you notice anything else that is making you feel unwell, even if it is not on this list.

Ask your doctor or pharmacist if you do not understand anything in this list.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

After using Noumed Diazepam


Keep your tablets in the original packaging until it is time to take them. If you take the tablets out of the blister pack, they may not keep well.

Keep Noumed Diazepam in a cool dry place where the temperature stays below 25°C.

Do not store diazepam, or any other medicines in a bathroom or near a sink.

Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.

Keep Noumed Diazepam where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking diazepam or the medicine has passed the expiry date, ask your pharmacist what to do with any tablets that are left over.

Where to go for further information

Pharmaceutical companies are not in a position to give people an individual diagnosis or medical advice. Your doctor or pharmacist is the best person to give you advice on the treatment of your condition.
