4. How do I take ANTENEX?

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

How much to take

  • Take ANTENEX exactly as your doctor has prescribed. Your doctor will tell you how many ANTENEX tablets to take each day and when to take them. The dose varies from person to person depending on age, the condition being treated and whether or not you are taking any other medicines.
  • The usual adult dose is between 5 and 40 mg daily. Children, elderly, those with kidney or liver problems and very ill patients may need to take less.
  • Follow the instructions provided and take ANTENEX until your doctor tells you to stop

When to take ANTENEX

  • ANTENEX can be taken up to three times a day. Your doctor will tell you how much you need to take.

How to take ANTENEX

  • The tablets can be taken with or without food.

How long to take ANTENEX for

  • Take ANTENEX only for as long as your doctor recommends.
  • Usually, ANTENEX should be taken for short periods only (for example 2 to 4 weeks). Continuous long-term use is not recommended unless advised by your doctor.

If you forget to take ANTENEX

ANTENEX should be used regularly at the same time each day.

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 the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.

Do not take a double dose to make up for the dose you missed.

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

If you take too much ANTENEX

If you think that you or anyone else has taken too much ANTENEX, urgent medical attention may be needed. If you take too much ANTENEX, you may feel drowsy, tired, confused, dizzy, have difficulty breathing, feel weak or become unconscious.

Benzodiazepines increase the effect of CNS depressants. When ANTENEX is combined with other CNS depressants, the effects of overdose are likely to be severe and may prove fatal.

You should immediately:

  • phone the Poisons Information Centre
    (Australia telephone 13 11 26) for advice, or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while taking ANTENEX?

Call your doctor straight away if you:

Things you should not do

Things to be careful of

Driving or using machines

Drinking alcohol

Tell your doctor if you drink alcohol.

Alcohol may increase the effects of ANTENEX. Your doctor may suggest that you avoid alcohol or reduce the amount of alcohol you drink while you are taking ANTENEX.

Looking after your medicine

  • Keep your tablets in the original packaging until it is time to take them.
  • Store below 30°C.

Store it in a cool dry place, away from moisture, heat or sunlight. For example, do not store it:

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
