Zolpidem is a sleeping pill. It’s used to treat insomnia (when you might have trouble getting to sleep and staying asleep). It helps you fall asleep more quickly and makes you less likely to wake up during the night. Zolpidem comes as tablets. It’s only available on prescription.
2. Belangrijkste feiten
- Zolpidem takes around 1 hour to work.
- You’ll usually take it for just a few weeks (up to 4 weeks).
- Common side effects are a metallic taste in your mouth or a dry mouth, and feeling sleepy in the daytime.

3. Who can and can’t take zolpidem
Zolpidem can be taken by most adults aged 18 and over.

Like all medicines, zolpidem can cause side effects in some people, although not everyone gets them.
Vaak voorkomende bijwerkingen
A common side effect is a bitter or metallic taste in your mouth or a dry mouth. Talk to a doctor or pharmacist if these side effects bother you or do not go away.
Using a mouthwash before bedtime may help. Choose one that’s good for a dry mouth, as some can make a dry mouth worse. You can also try taking sips of water and keep some water by your bed at night.
Some people can get serious side effects with zolpidem. Stop taking zolpidem and call a doctor as soon as possible if you:
- develop memory loss (amnesia)
- see or hear things that are not real (hallucinations)
- fall over – particularly if you are over the age of 65
- think things that are not true – these are called delusions
- feel low or sad – this could be a sign of depression
Ernstige allergische reactie
In rare cases, it’s possible to have a serious allergic reaction (anaphylaxis) to zolpidem.
Immediate action required: Call 999 or go to A&E if:
- u krijgt huiduitslag die kan bestaan uit jeukende, rode, gezwollen, blaren of vervellende huid
- je piept
- je krijgt een beklemd gevoel op de borst of keel
- je hebt moeite met ademhalen of praten

U zou een ernstige allergische reactie kunnen hebben en mogelijk onmiddellijke behandeling in het ziekenhuis nodig hebben.
These are not all the side effects of zolpidem. For a full list, see the leaflet inside your medicines packet.
U kunt elke vermoedelijke bijwerking melden aan het UK Safety Scheme.
6. Pregnancy and breastfeeding
Do not take zolpidem if you’re pregnant, as it may harm your baby. There’s some evidence that taking zolpidem can increase the risk of your baby coming early (before 37 weeks) and having a lower birthweight.
Taking zolpidem right up until you go into labour may increase your baby’s chances of having withdrawal symptoms as soon as they’re born.
For more information about how zolpidem can affect you and your baby during pregnancy, read this leaflet on the Best Use of Medicines in Pregnancy (BUMPS) website.
Zolpidem and breastfeeding
If a doctor or health visitor says that your baby is healthy, it’s OK to take zolpidem while breastfeeding. Zolpidem passes into breast milk in very small amounts.
However, it’s best to try some practical steps to help you sleep first. The side effects of taking zolpidem could make you feel too tired to breastfeed and look after your baby.
Do not share a bed with your baby if you’re taking zolpidem.
If you notice that your baby is not feeding as well as usual, or seems unusually sleepy, or if you have any other concerns about your baby, talk to a health visitor or doctor as soon as possible.
Non-urgent advice: Tell a doctor or a pharmacist if you’re:
- proberen zwanger te worden
- borstvoeding geven
7. Cautions with other medicines
Some medicines and zolpidem can interfere with each other and increase your chance of having side effects. Certain medicines may increase the drowsy (sedating) effects of zolpidem.
Speak to a doctor or a pharmacist before starting on zolpidem if you take any of the following:
- drowsy antihistamines such as chlorphenamine or promethazine
- medicines to treat schizophrenia and bipolar disorder
- medicines to treat depression
- medicines for epilepsy
- medicines to calm or reduce anxiety
- medicines for sleep problems
- medicines used to treat fungal infections (such as ketoconazole and itraconazole)
- ritonavir (a medicine used to treat HIV infections)
- strong painkillers (such as codeine, methadone, morphine, oxycodone, pethidine or tramadol)
Mixing zolpidem with herbal remedies and supplements
- Do not take any herbal remedies that make you feel sleepy while taking zolpidem.
- These can increaase the drowsy (sedating) effects of your medicine.
For safety, tell a doctor or pharmacist if you’re taking any other medicines, including herbal remedies, vitamins or supplements.
8. Common questions
Hoe werkt zolpidem?
Zolpidem helps improve your sleep by boosting a chemical in your brain called gamma-aminobutyric acid (GABA). GABA blocks some of the neurotransmitters that send messages in the brain. This has a calming effect on the brain, which helps you get to sleep.
Hoe lang duurt het voordat het werkt?
Zolpidem zou binnen 1 uur na inname moeten werken.
Hoe zal zolpidem me laten voelen?
Zolpidem will make you feel sleepy (drowsy). It affects people in different ways and some people may feel sleepier than others.
When you first start taking this medicine, you may feel sleepy during the daytime for the first few days. Be aware that this can affect you being able to carry out everyday tasks.
Zal ik slaapwandelen met zolpidem?
Some people have reported doing things like sleepwalking, making food and making phone calls while they’re asleep after taking zolpidem. They do not remember when they wake up.
This is more likely to happen if you take zolpidem with alcohol, or medicines for mental health problems like depression or anxiety. If this happens to you, stop taking zolpidem and go back to the doctor for advice.
Hoe lang zal ik het nemen?
You’ll usually be prescribed zolpidem for just 2 to 4 weeks. This is because your body gets used to this medicine quickly. After taking it for a few weeks, it’s unlikely to have the same effect. Your body can also become dependent on it.
If you still have problems sleeping after you finish your course of zolpidem, try the lifestyle changes recommended below. See the doctor again if these changes do not help.
Kan ik verslaafd raken aan zolpidem?
If you just take it for a few weeks, you’re unlikely to become addicted to zolpidem. However, you may become dependent on this medicine if you take it for longer than 4 weeks. Ask a doctor or pharmacist for advice about stopping zolpidem.
They can help you come off your medicine gradually if you have been taking it for a long time, or if you’re worried about becoming dependent on it.
Is het veilig om voor een lange tijd te nemen?
Zolpidem should only be used short term (usually up to 4 weeks) for sleep problems. This is because your body can become dependent on it.
See a doctor if you feel you need to take it for longer than 4 weeks. They will be able to discuss your sleep problems and recommend other things that may help.
Wat gebeurt er als ik stop met het innemen?
If you have been taking zolpidem for less than 4 weeks, you’re unlikely to have any problems. If you have been taking zolpidem for longer than 4 weeks, do not stop taking this medicine suddenly. You may get withdrawal symptoms.
Your insomnia can come back and it may be worse than before. You may also feel anxious, restless and have mood changes. You may become very sensitive to light, noise and being touched.
Speak to the doctor first about coming off zolpidem. They may recommend reducing your dose of zolpidem slowly, over a few days or weeks. This will help prevent withdrawal symptoms if you’ve been taking it for more than 4 weeks.
Mag ik autorijden of fietsen?
If zolpidem makes you sleepy, dizzy or clumsy, gives you blurred vision or you cannot concentrate or make decisions, do not drive a car, ride a bike or operate machinery. This may be more likely when you first start taking zolpidem, but could happen at any time – for example, when starting another medicine.
It’s an offence to drive a car if your ability to drive safely is affected. It’s your responsibility to decide if it’s safe to drive. If you’re in any doubt, do not drive. GOV.UK has more information on the law on drugs and driving Talk to a doctor or pharmacist if you’re unsure whether it’s safe for you to drive while taking zolpidem.
Zal het mijn vruchtbaarheid beïnvloeden?
There’s no firm evidence to suggest that taking zolpidem will reduce fertility in either men or women. But speak to a pharmacist or doctor if you and your partner are trying for a baby. Your doctor may review your treatment.
Heeft het invloed op mijn anticonceptie?
Zolpidem does not affect how contraception works, including the combined pill and emergency contraception.
Is er eten of drinken dat ik moet vermijden?
Do not have drinks that contain caffeine while you’re on zolpidem. These include coffee, tea, cola and energy drinks and hot chocolate. Caffeine has the opposite effect of zolpidem on your body and stops it working.
Kan ik er alcohol bij drinken?
No. Do not drink alcohol while you’re on zolpidem. Alcohol and zolpidem together can make you sleep very deeply, so you do not breathe properly and can have difficulty waking up.
Hoe lang blijft het in mijn systeem?
Zolpidem does not stay in your system for more than about 12 hours. But some people feel sleepy the next morning when they wake up.
If this happens to you, do not do any activities that require you to be fully alert, such as driving, cycling, or using tools or machinery.
Zullen recreatieve drugs het beïnvloeden?
Using cannabis with zolpidem will make its sleep-inducing (sedative) effects worse. You could go into a very deep sleep, where you have difficulty waking up.
Using heroin or methadone with zolpidem may also increase the sedative effects of both drugs. Again, you could go into a very deep sleep and have difficulty waking up. Talk to a doctor if you think you might use recreational drugs while you’re taking zolpidem.
Kunnen veranderingen in levensstijl helpen bij slapeloosheid?
There are a number of things you can do to help yourself beat insomnia:
-set regular times for going to bed and waking up
-relax before bedtime – try taking a warm bath or listening to calming music
-use thick curtains or blinds, an eye mask and earplugs to stop you being woken up by light and noise
-avoid caffeine, cigarettes (or e-cigarettes), alcohol, heavy meals and exercise for a few hours before going to bed
-do not watch TV or use phones, tablets or computers just before going to bed
-do not nap during the day
-write a list of your worries, and any ideas about how to solve them, before you go to bed to help you forget about them until the morning
