What ZOLPIDEM AN is used for
ZOLPIDEM AN is a prescription medicine that your doctor has prescribed for you. Do not share it with anyone.
ZOLPIDEM AN is the brand name of a medicine called Zolpidem tartrate.
ZOLPIDEM AN is used to initiate sleep in those with sleeping difficulties, also called insomnia. The cause of sleeping problems should be known, if possible. The causes should be treated before ZOLPIDEM AN, or any hypnotic is prescribed.
It should not be used for more than 4 weeks at a time. Continuous long term use is not recommended unless advised by your doctor.
The use of ZOLPIDEM AN may lead to dependence on the medicine.
ZOLPIDEM AN has a different chemical structure to any other sleeping tablet that is currently available in Australia.
ZOLPIDEM AN works by binding to special sites in the brain which produce sleep.
Your doctor will have explained why you are being treated with ZOLPIDEM AN and told you what dose to take. Follow these instructions carefully. They may differ from the information contained in this leaflet.

In particular, tell your doctor if you take any of the following:
- Other sleeping tablets, sedatives or tranquilizers

- Medicines to treat bacterial infections such as rifampicin, erythromycin and clarithromycin

Let your doctor know if you have used Zolpidem AN before and if you had any problems with it.
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 a higher chance of becoming addicted to sleep medicines.
If you have been addicted to alcohol or drugs in the past, it is important to tell your doctor before starting ZOLPIDEM AN.
Use with caution in the elderly or debilitated patient.
How to take ZOLPIDEM-PS
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How much to take
The usual adult dose of ZOLPIDEM AN is 10 mg.
If you are over 65 years of age the dose is 5 mg (half of the 10 mg) ZOLPIDEM AN at night.
If you have a liver problem, you should start with 5 mg (half of the 10 mg) ZOLPIDEM AN, taken at night. If necessary, this can be increased to 10 mg.
How to take it
ZOLPIDEM AN 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.
How long to take it
It should not be used for more than 4 weeks at a time. Continuous long term use is not recommended unless advised by your doctor.
If you forget to take your dose
If you forget to take ZOLPIDEM-PS before you go to bed and you wake up late in the night or early morning, do not take any ZOLPIDEM AN 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.
If you take too much (overdosage)
Some signs and symptoms of taking too much ZOLPIDEM AN include severe drowsiness, clumsiness or unsteadiness, mental or mood changes, unusual tiredness or weakness and unconsciousness.
If you or someone else has taken too much ZOLPIDEM AN, immediately telephone your doctor or the Poisons Information Centre (13 11 26), or go to Accident and Emergency at your nearest hospital. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are taking ZOLPIDEM AN
Things you must do
Always follow your doctors instructions carefully.
Tell your doctor if you become pregnant while taking Zolpidem AN.
If you are about to start taking a new medicine, tell your doctor and pharmacist that you are taking ZOLPIDEM AN.
ZOLPIDEM AN 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 tranquilisers or sleeping medicines
- Prescription pain medicines or narcotics
- Medicines for seizures
- Muscle relaxants
- 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 AN.
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 AN.
After taking ZOLPIDEM AN 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 your doctor may think it was not effective and change your treatment unnecessarily.
If you develop any unusual and strange thoughts or abnormal behaviour while you are taking ZOLPIDEM AN, 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 AN 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 it for a long time, may cause some unwanted side effects such as mood changes, anxiety and restlessness.
Your doctor will advise you to slowly reduce your dose of ZOLPIDEM AN before you can stop taking it completely.
Do not use ZOLPIDEM AN 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 AN for a longer time than your doctor has prescribed. ZOLPIDEM AN should be taken for short periods only (maximum 4 weeks), unless advised by your doctor.
ZOLPIDEM AN 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 AN at night, you may still be drowsy or dizzy early the next day.
Do not take Zolpidem AN with alcohol, as combining Zolpidem AN 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 for 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
- Nausea and vomiting
- Muscle weakness
These are more common side effects of Zolpidem AN. 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 behavior. 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 AN 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
These are very serious side effects. If you have them, you may have had a serious allergic reaction to Zolpidem AN. You may need urgent medical attention or hospitalization. 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 and they worry you.
After taking Zolpidem AN
Keep your tablets in the blister pack until it is time to take them. If you take the tablets out of the blister pack they may not keep well.
Keep your tablets in a cool dry place where the temperature stays below 25°C and protect from light.
Do not store it or any other medicine in the bathroom or near a sink.
Do not leave it in the car or on window sills. Heat and dampness can destroy some medicines.
Keep it where children cannot reach it. A locked cupboard at least one-and-a-half meters above the ground is a good place to store medicines.
If your doctor tells you to stop taking this medicine, or the tablets have passed their expiry date, ask your pharmacist what to do with any that are left over.
