How to take this medicine
Follow carefully all directions given to you by your doctor. Their instructions may be different to the information in this leaflet.
If you do not understand any written instructions, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
Do not stop taking your medicine or change your dosage without first checking with your doctor. The usual adult dose of zolpidem is 10 mg.
If you are over 65 years of age or debilitated in any way, the usual dose is 5 mg at night.
If you have a liver problem, the usual dose is 5 mg. This can be increased to 10 mg if advised by your doctor.
How to take it
Swallow the tablets whole with a full glass of water unless your doctor has told you to take half a tablet.
Do not crush or chew the tablets.
When to take it
Take zolpidem immediately before you go to bed because it puts you to sleep quite quickly. It also works more quickly if you take it on an empty stomach.
Zolpidem should only be taken when you are able to get a full night's sleep (7 to 8 hours) before you need to be active and alert again.
How long to take it for
Zolpidem should only be used for short periods (treatment should not exceed 4 weeks). Continuous long term use is not recommended unless advised by your doctor.
If you forget to take it
If you forget to take zolpidem before you go to bed, and you wake up late in the night or very early in the morning, do not take it. If you take it later than normal, you may have trouble waking at your normal time.
Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.
If you take too much (overdose)
If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively, go to the Accident and Emergency department at your nearest hospital.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much zolpidem your consciousness may be impaired, (ranging from drowsiness to light coma).
While you are taking this medicine
Things you must do
Tell your doctor that you are taking this medicine if:
- you are about to be started on any new medicine
- you are pregnant or are planning to become pregnant. If you become pregnant while you are taking zolpidem, stop taking it and tell your doctor immediately
- you are breast-feeding or are planning to breast-feed. Breast-feeding is not recommended whilst taking zolpidem
- you are about to have any blood tests
- you are going to have surgery or an anaesthetic or are going into hospital.
Go to your doctor regularly for a check-up.
If the tablets have not started to work after 7 to 14 days go to your doctor to discuss what to do next.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.
Things you must not do
Do not give this medicine to anyone else, even if their symptoms seem similar to yours.
Do not take your medicine to treat any other condition unless your doctor tells you to.
Do not stop taking your medicine, or change the dosage, without first checking with your doctor. If you stop taking this medicine suddenly, there is a chance that your original symptoms of sleeplessness may become worse, or you get withdrawal symptoms such as muscle pain, sensitivity to light, touch or sound, headache, anxiety, tension, restlessness, confusion, strange thoughts, numbness, tingling, mood changes, irritability or, feeling not part of your body.
Do not drink alcohol before, during or immediately after taking this medicine. This can increase the risk of side effects.
Things to be careful of
Because zolpidem will make you sleepy, you should not operate dangerous machinery or drive motor vehicles for at least 8 hours after you take it. You should also be careful the next morning when you wake up. Make sure you know how you react to zolpidem before you drive a car or operate machinery. This is especially important if you are taking other drugs that also make you drowsy, because they may make you even more drowsy when taken with zolpidem.
Be careful if you are over the age of 65, unwell or debilitated in some way, or taking other medicines. You may be more sensitive to some of the side effects of zolpidem.
You must not have alcohol in your bloodstream while you are taking zolpidem. The effects of alcohol could be made worse while taking zolpidem.
Possible side effects
Tell your doctor as soon as possible if you do not feel well while you are taking zolpidem or if you have any questions or concerns.
Do not be alarmed by the following lists of side effects. You may not experience any of them. All medicines can have side effects. Sometimes they are serious but most of the time they are not.
Tell your doctor if you notice any of the following:
- worsened insomnia
- temporary amnesia
- diarrhoea, nausea and vomiting
- abdominal pain
- muscle weakness
- infections of the nose throat and chest.
Tell your doctor as soon as possible if you notice any of the following. These may be serious side effects and you may need medical attention:
- unexpected changes in behaviour, such as anger, aggression or rage, worsened insomnia, nightmares, confusion, agitation, restlessness, irritability, stimulation, excitement, hallucinations, delusions 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 having these strange experiences. These side effects can also occur without the presence of alcohol intake. They can also occur at the dosage prescribed by your doctor. However, there is an increased risk of side effects if you take more than the recommended dose.
Some sleep medicines may cause short-term memory loss. 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.
Other side effects not listed above may occur in some patients.
Sleep medicines should, in most cases, be used only for short periods of time. If your sleep problems continue, consult your doctor.
Some sleep medicines can cause dependence, especially when they are used regularly for longer than a few weeks. People who have been dependent 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.
Sometimes when medicines are stopped suddenly, after being used for a long time, withdrawal symptoms may occur. Symptoms of withdrawal may include muscle pain, sensitivity to light, touch or sound, headache, anxiety, tension, restlessness, confusion, strange thoughts, numbness, tingling, mood changes, irritability or feeling not part of your body.
In some cases, your insomnia may appear worse for a short time. Speak to your doctor if this occurs.
Patients taking part in trials have not had any problems when they stopped taking zolpidem.
However, let your doctor know if you have any problems when you stop taking zolpidem.
If you think you are having an allergic reaction to zolpidem, do not take any more of this medicine and tell your doctor immediately or go to the Accident and Emergency department at your nearest hospital.
Symptoms of an allergic reaction may include some or all of the following:
- cough, shortness of breath, wheezing or difficulty breathing
- swelling of the face, lips, tongue, throat or other parts of the body
- rash, itching or hives on the skin
- hay fever-like symptoms.
