Loratadine pour les allergies

About loratadine

Loratadine belongs to a group of medicines called antihistamines - it is an anti-allergy medicine. It stops the effects of a naturally occurring substance called histamine and this helps to relieve the symptoms of allergies such as hay fever and urticaria.

Exposure to substances such as pollen, pet fur, house dust or insect bites can cause your body to produce allergic symptoms. Les cellules de la muqueuse de votre nez et de vos yeux libèrent de l'histamine lorsqu'elles entrent en contact avec ces substances. Cela entraîne une inflammation du nez et des yeux, provoquant des symptômes tels que des éternuements et des yeux larmoyants.

L'urticaire est une affection où une éruption cutanée prurigineuse se développe. L'éruption peut être déclenchée par une allergie à une substance telle qu'un savon ou un détergent.

Loratadine can be prescribed for you by a doctor or dentist, or you can buy it without a prescription at pharmacies and other retail outlets. Tablet formulations are generally suitable for adults and older children, whereas oral liquid medicine is available for younger children. Loratadine is not suitable for children under 2 years of age.

To make sure that this is the right treatment for you (or your child), before you (or they) start taking loratadine it is important that you discuss the treatment with a doctor or pharmacist if:

• You/they are pregnant, trying for a baby or breastfeeding.

• You/they have any liver problems. If so, the recommended dose may need to be reduced.

• Vous/ils ont un trouble sanguin héréditaire rare appelé porphyrie.

• Vous/eux prennent ou utilisent d'autres médicaments. Cela inclut tous les médicaments en cours d'utilisation disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et complémentaires.

• Vous/ils ont déjà eu une réaction allergique à un autre antihistaminique, ou à tout autre médicament.

• Before starting the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about loratadine dosage, and it will also provide you with a full list of side-effects which could be experienced from taking it.

• Recommended doses of loratadine are:
  

  • Pour les adultes et les enfants de plus de 12 ans : 10 mg une fois par jour.

  • For children aged over 2 years and weighing 31 kg or more: 10 mg taken once a day.

  • For children aged over 2 years and weighing less than 31 kg: 5 mg taken once a day.

• If you are giving loratadine liquid medicine to a child, make sure you follow the dosing instructions on the bottle carefully so that you measure out the correct dose for the weight of your child.

• You can take loratadine either with or without food. Some people find it helps to swallow the tablets with a drink of water.

• Si vous oubliez de prendre une dose, ne vous inquiétez pas, prenez simplement la prochaine dose lorsque cela est nécessaire, puis continuez comme avant. Ne prenez pas deux doses en même temps pour compenser une dose oubliée.

• Most people only need to take an antihistamine for a short while when they have symptoms. You should stop taking loratadine once your symptoms have eased.

• Although loratadine is classed as a non-drowsy antihistamine, it can still cause drowsiness in a few people. If you are affected by drowsiness, do not drive, do not use a bicycle, and do not use tools or machines.

• If you drink alcohol while you are taking loratadine, be aware of its effects on you and do not drink more than moderate amounts. Alcohol can increase the risk of experiencing side-effects from antihistamines - for instance, you may feel more drowsy than usual.

• Si vous subissez une opération, ou tout traitement ou test (en particulier s'il s'agit de tester une allergie), assurez-vous de dire que vous prenez un antihistaminique.

• Si vous achetez des médicaments 'en vente libre', vérifiez avec un pharmacien qu'ils sont adaptés à prendre avec un antihistaminique. En effet, un certain nombre d'autres médicaments peuvent augmenter le risque d'effets secondaires.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them.

The best place to find a full list of the side-effects which can be associated with your medicine, is from the manufacturer's printed information leaflet supplied with the medicine.
