About lormetazepam
Typ av medicin | A benzodiazepine |
Används för | Insomnia in adults |
Tillgänglig som | Tabletter |
Poor sleep (insomnia) is fairly common but does not usually last for long. If you have problems sleeping, it may mean that you have difficulty getting off to sleep, or you may wake up for long periods during the night, or you may wake up too early in the morning. 'Sleeping tablets' are considered a last resort, but are sometimes prescribed for a short period of time to help with a particularly bad spell of insomnia.
Lormetazepam works by affecting the way certain brain chemicals (neurotransmitters) transmit messages. This has a calming effect and helps you to sleep. It works well in the short term, but lormetazepam is not normally advised for more than 1-3 weeks. If you take it for longer, the medicine may lose its effect (you may become tolerant to the effect), and if you stop it you may develop withdrawal symptoms. You may need to keep taking the medicine to avoid the withdrawal symptoms. This is known as drug dependence.
In addition, you may become addicted to lormetazepam. Addiction is different from dependence. You have an overwhelming craving for a drug, so that you feel compelled to take it even though it is harming you physically or affecting your life and relationships.
Before taking lormetazepam
Tillbaka till innehållSome medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking lormetazepam it is important that your doctor knows:
Om du är gravid eller ammar.
If you have any breathing problems.
Om du har några problem med hur din lever fungerar, eller om du har några problem med hur dina njurar fungerar.
If you have a mental health problem. This includes conditions such as psychosis, depression, obsessive conditions, phobias and personality disorders.
If you have ever had a drug or alcohol addiction.
If you have a condition causing severe muscle weakness, called myasthenia gravis.
If you have a rare inherited blood disorder called porphyria.
Om du någonsin har haft en allergisk reaktion mot en medicin.
Om du tar några andra läkemedel. Detta inkluderar alla läkemedel som kan köpas utan recept, samt växtbaserade och komplementära läkemedel.

How to take lormetazepam
Tillbaka till innehållBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about lormetazepam, and will also provide you with a full list of the side-effects which you could experience from taking it.
Your doctor may recommend that you take one tablet each evening for a few days, or only on certain days of the week. Take lormetazepam exactly as your doctor tells you to. Take the tablet just before you go to bed.
Få ut det mesta av din behandling
Tillbaka till innehållTry to keep any appointments with your doctor. This is so your doctor can check how you are feeling.
The effects of lormetazepam can last into the following day; please be aware that it is likely to affect your reactions and your ability to drive. It is an offence to drive while your reactions are impaired, so do not drive until you know how you react, especially when you first start treatment. Even if your driving ability is not impaired, should you drive, you are advised to carry with you some evidence that the medicine has been prescribed for you - a repeat prescription form or a patient information leaflet from the pack is generally considered suitable.
Do not drink alcohol while you are on lormetazepam. It will increase the risk of sedative side-effects.
If you are due to have an operation or any dental treatment, please tell the person carrying out the treatment that you are taking a benzodiazepine. This is because lormetazepam increases the effects of some anaesthetics.
Your doctor is likely to recommend that you reduce your dose gradually when it is time to stop taking it. This is to reduce the risk of you experiencing withdrawal effects. Follow carefully any instructions your doctor gives to you.

Can lormetazepam cause problems?
Tillbaka till innehållAlong with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with lormetazepam. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
Common lormetazepam side-effects | Vad kan jag göra om jag upplever detta? |
Feeling sleepy, dizzy or light-headed during the day | Kör inte och använd inte verktyg eller maskiner. Drick inte alkohol |
Feeling unsteady or weak | Om det är besvärligt, prata med din läkare |
Important: because of side-effects such as dizziness, muscle weakness and feeling sleepy or tired, taking this medicine may make you more likely to have a fall or an accident. Please take care, especially when getting up during the night or using stairs. Take extra care if you are frail, elderly or have any other risk factors for falls.
Om du upplever några andra symtom som du tror kan bero på tabletterna, tala med din läkare eller apotekare för vidare råd.
