About lormetazepam
Tipo de medicamento | Una benzodiacepina |
Utilizado para | Insomnia in adults |
Disponible como | Tabletas |
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
Some 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:
Si está embarazada o en periodo de lactancia.
Si tiene problemas respiratorios.
Si tiene algún problema con el funcionamiento de su hígado, o si tiene algún problema con el funcionamiento de sus riñones.
Si tiene un problema de salud mental. Esto incluye enfermedades como psicosis, depresión, obsesiones, fobias y trastornos de la personalidad.
Si alguna vez has tenido una adicción a las drogas o al alcohol.
Si padece una enfermedad que provoca debilidad muscular grave, denominada miastenia grave.
Si padece un raro trastorno sanguíneo hereditario llamado porfiria.
Si alguna vez ha tenido una reacción alérgica a un medicamento.
Si está tomando otros medicamentos. Esto incluye todos los medicamentos que se pueden comprar sin receta, así como las hierbas medicinales y los medicamentos complementarios.

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.

Try 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.

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.

Feeling sleepy, dizzy or light-headed during the day | No conduzca ni utilice herramientas o máquinas. No beba alcohol |
Feeling unsteady or weak | En caso de molestias, hable con su médico |
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.
Si experimenta cualquier otro síntoma que crea que puede deberse a los comprimidos, hable con su médico o farmacéutico para que le aconsejen.
