About levomepromazine
Type de médicament | Un médicament antipsychotique |
Utilisé pour | Easing distressing symptoms in palliative care; easing symptoms of schizophrenia |
Aussi appelé | Nozinan®, Leverol® |
Disponible sous forme de | Tablets, injection |
Levomepromazine is sometimes given as an injection to people who are terminally ill to help ease distressing symptoms such as pain, feeling sick (nausea), restlessness, and confusion. It works on the balance of chemical substances acting in the brain. If you (or a family member) have been prescribed levomepromazine for this reason, your specialist or home-care team will be able to give you more information about the treatment.
Levomepromazine is also prescribed to relieve symptoms of la schizophrénie. Schizophrenia is a mental health problem which affects your thoughts, feelings or behaviours. Symptoms of schizophrenia include hearing, seeing, or sensing things that are not real, having mistaken beliefs, and feeling unusually suspicious. The rest of this document provides information about levomepromazine when it has been prescribed for schizophrenia.
Before taking levomepromazine
Retour au sommaireSome medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking levomepromazine it is important that your doctor knows:
Si vous êtes enceinte ou si vous allaitez.
Si vous avez une maladie cardiaque ou une maladie des vaisseaux sanguins.
Si vous avez des problèmes de foie, de reins ou de prostate.
Si vous avez des problèmes de respiration.
If you have any of the following: epilepsy, la maladie de Parkinson, dépression, raised pressure in your eye (glaucoma) or a condition which causes muscle weakness, called myasthénie grave.
If you have ever had yellowing of your skin or of the whites of your eyes (jaunisse) or a blood disorder.
Si vous avez une tumeur sur votre glande surrénale (une affection appelée phéochromocytome).
Si vous avez eu une réaction allergique à un médicament.
Si vous prenez ou utilisez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et complémentaires.

How to take levomepromazine
Retour au sommaireBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about levomepromazine and it will also provide you with a full list of the side-effects which you may experience from taking the tablets.
Take levomepromazine exactly as your doctor tells you to. When you first start taking levomepromazine, your doctor may give you a small dose and then gradually increase it. It is usually prescribed as three doses a day. The directions for taking the tablets will be printed on the label of the pack to remind you about what the doctor said to you.
Try to get into the habit of taking your doses at the same times of day each day, as this will help you to remember to take them regularly. You can take levomepromazine tablets either before or after meals. Swallow the tablets with a drink of water.
If you forget to take a dose, leave out the missed dose but make sure that you remember to take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.
Tirer le meilleur parti de votre traitement
Retour au sommaireYour treatment will require careful monitoring to make sure that you get the best possible benefit from levomepromazine. Keep your regular doctor's appointments so that your progress can be checked. You will need to have some tests from time to time during the treatment.
Treatment with levomepromazine for schizophrenia is usually long-term unless you experience an adverse effect. Keep taking the tablets unless your doctor tells you otherwise. Stopping levomepromazine suddenly can cause problems and your doctor may want you to reduce your dose gradually if this becomes necessary.
Alcohol increases the risk of side-effects from levomepromazine, so it is best avoided.
If you have diabetes you may need to check your blood glucose more frequently, as levomepromazine may affect the levels of sugar in your blood. Your doctor will advise you about this.
Levomepromazine can cause your skin to become more sensitive to sunlight than normal. Use a sunscreen that protects against UVA light and has a sun protection factor (SPF), especially in strong sunlight or until you know how your skin reacts. Do not use sunbeds.
If you are due to have any medical or dental treatment, tell the person carrying out the treatment which medicines you are taking. This is important because levomepromazine may interfere with any anaesthetic you receive.
If you buy or take any 'over-the-counter' medicines or herbal remedies, please check with a pharmacist that they are suitable for you to take with levomepromazine.
