ZOLPIDEM-DP is a prescription medicine that your doctor has prescribed for you. Do not share it with anyone. ZOLPIDEM-DP is the brand name of a medicine called Zolpidem tartrate.

What is it used for and how does it work?

ZOLPIDEM-DP is used to initiate sleep in those with sleeping difficulties, also called insomnia. The cause of sleeping problem should be known, if possible. The causes should be treated before ZOLPIDEM-DP, or any hypnotic is prescribed. It should not be used for more than 4 weeks at a time. Continuous long term use in not recommended unless advised by your doctor. The use of ZOLPIDEM-DP may lead to dependence on the medicine.

ZOLPIDEM-DP has a different chemical structure to any other sleeping tablet that is currently available in Australia. ZOLPIDEM-DP works by binding to special sites in the brain which produce sleep. Your doctor will have explained why you are being treated with ZOLPIDEM-DP and told you what dose to take. Follow these directions carefully. They may differ from the information contained in this leaflet.

  • Any other substances, including foods, preservatives or dyes.

  • Kidney problems
  • Liver problems
  • Lung disease
  • Fits or convulsions
  • Depression, psychosis or schizophrenia
  • Drug and/or alcohol addiction
  • If you have any problems with your breathing or if you often snore while you are asleep

Some medicines can cause dependence, especially when they are used regularly for longer than a few weeks. People who have been dependant on alcohol or other drugs in the past may have higher chance of becoming addicted to sleep medicines.

ZOLPIDEM-DP should be taken just before you go to bed because it puts you to sleep quite quickly. It works more quickly if you take it on an empty stomach. The usual adult dose of ZOLPIDEM-DP is 10 mg. If you are over 65 years of age the dose is 5mg (half of the 10mg) ZOLPIDEM-DP at night. If you have a liver problem, you should start with 5 mg (half of the 10mg) ZOLPIDEM-DP, taken at night. If necessary, this can be increased to 10 mg.

If you forget to take your dose

If you forget to take ZOLPIDEM-DP before you go to bed and you wake up late in the night or early morning, do not take any ZOLPIDEM-DP as you may have trouble waking in the morning.

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

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

Things you must do

  • Always follow your doctor's instructions carefully.
  • Tell your doctor if you become pregnant while taking ZOLPIDEM-DP.
  • If you are about to start taking a new medicine, tell your doctor and pharmacist that you are taking ZOLPIDEM-DP. ZOLPIDEM-DP will add to the effects of alcohol and other central nervous system (CNS) depressant medicines that cause drowsiness. Some examples of CNS depressants are sedating antihistamines or medicine for hay fever, other allergies, or colds; sedative tranquillisers or sleeping medicines; prescription pain medicines or narcotics; barbiturates; medicine for seizures; muscle relaxants; or anaesthetics including some dental anaesthetics. Check with your doctor or pharmacist before taking any of the above or any other medicines with or without a prescription while you are using ZOLPIDEM-DP.
  • Keep all your doctor's appointments so that your progress can be monitored.
  • Discuss with your doctor any problems or difficulties during or after taking ZOLPIDEM-DP. After taking ZOLPIDEM-DP for insomnia, you may have difficulty sleeping (rebound insomnia) for the first few nights after you stop taking it.
  • Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise you doctor may think it was not effective and change you treatment unnecessarily.
  • If you develop any unusual and strange thoughts or abnormal behaviour while you are taking ZOLPIDEM-DP, be sure to discuss it with your doctor. Some changes that have occurred in people taking this medicine are like those seen in people who drink alcohol and then act in a manner that is not normal. Other changes may be more unusual and extreme, such as aggression, hallucinations (seeing, hearing, or feeling things that are not there), and unusual excitement, nervousness, or irritability.
  • When sleep medicines are used every night for more than a few weeks, they may lose their effectiveness to help you sleep. Sleep medicines should in most cases, be used only for short periods of time. If your sleep problems continue, consult your doctor.

Things you must not do

  • Do not stop taking ZOLPIDEM-DP or lower the dose without checking with your doctor. Stopping this medicine suddenly, especially when you are on a high dose or have been taking if for a long time, may cause some unwanted effects such as mood changes, anxiety and restlessness. Your doctor will advise you to slowly reduce your dose of ZOLPIDEM-DP before you can stop taking it completely.
  • Do not use ZOLPIDEM-DP to treat any other complaint unless your doctor says so.
  • Do not give this medication to anyone else, even if their symptoms seem similar to yours.
  • Do not take ZOLPIDEM-DP for a longer time than your doctor has prescribed. ZOLPIDEM-DP should be taken for short periods only (maximum 4 weeks), unless advised by your doctor.
  • ZOLPIDEM-DP will make you sleepy, dizzy or light- headed and may therefore affect alertness. Do not drive motor vehicles or operate dangerous machinery for 8 hours after you take it. You should also be careful the next morning when you wake up. Even if you take ZOLPIDEM-DP at night, you may still be drowsy or dizzy early the next day.
  • Do not take ZOLPIDEM-DP with alcohol, as combining ZOLPIDEM-DP and alcohol can increase the risk of sleep walking and other associated behaviours (see SIDE EFFECTS).

Things to be careful of

Be careful if you are elderly, unwell or taking other medicines. Some people may experience side effects such as drowsiness, confusion, dizziness and unsteadiness, which may increase the risk of a fall.

All medicines can have unwanted effects. Sometimes they are serious, most of the time they are not. Your doctor or pharmacist has weighed the risk of using this medicine against the benefits they expect it will have on you. Do not be alarmed by this list of possible side effects. You may not experience any of them.

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

  • Drowsiness, dizziness or light-headedness
  • Headache
  • Nausea and vomiting
  • Diarrhoea
  • Muscle weakness

These are the more common side effects of ZOLPIDEM-DP. Mostly, these are mild and short-lived.

Some sleep medicines may cause a special type of memory loss "anterograde amnesia". When this occurs, a person may not remember what has happened for several hours after taking the medicine. This is usually not a problem since most people fall asleep after taking the medicine. To reduce this risk, ensure that you are able to get a full night's sleep (7 to 8 hours) before you need to be active again.

Less common side effects include:

  • Unexpected changes in behaviour. These have included rage reactions, worsened insomnia, confusion, agitation, hallucinations and other forms of unwanted behaviour.
  • Sleep walking, driving motor vehicles and other unusual and on some occasions dangerous behaviours whilst apparently asleep. These have also included preparing and eating food, making phone calls or having sexual intercourse. People experiencing these effects have had no memory of the events.

Alcohol can increase the risk of sleep walking and other related behaviours. These side effects can also occur without the presence of alcohol.

Although these side effects can occur at the usual recommended doses, the risk of these behaviours occurring may also be increased if you take more than the recommended dose.

If any of the following happen, stop taking ZOLPIDEM-DP and tell your doctor immediately, or go to Accident and Emergency at your nearest hospital:

  • Skin rashes or hives, excessive sweating, swelling of the face, lips, mouth or throat which may cause difficulty in swallowing or breathing, fainting.

These are very serious side effects. If you have them, you may have had a serious allergic reaction to ZOLPIDEM-DP. You may need urgent medical attention or hospitalisation. All of these side effects are very rare.

Other side effects not listed above may also occur in some people. Tell your doctor if you notice any other effects.
