Cetirizine pour les allergies

About cetirizine

Cetirizine 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. Cells in the lining of your nose and eyes release histamine when they come into contact with these substances. This leads to inflammation in your nose and eyes, which produces symptoms such as sneezing and watery eyes.

L'urticaire est une affection caractérisée par l'apparition d'une éruption cutanée accompagnée de démangeaisons. L'éruption peut être déclenchée par une allergie à une substance telle qu'un savon ou un détergent.

Cetirizine 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 and capsule formulations are generally suitable for adults and older children, whereas oral liquid medicine is available for younger children. Cetirizine is not suitable for children under 2 years of age.

Before taking cetirizine

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

• Vous êtes enceinte, vous essayez d'avoir un enfant ou vous allaitez.

• You/they have any kidney problems. If so, the recommended dose will be reduced.

• You/they have epilepsy.

• You/they have a rare inherited blood disorder called porphyria.

• You/they are taking or using any other medicines. This includes any medicines being taken which are available to buy without a prescription, as well as herbal and complementary medicines.

• You/they have ever had an allergic reaction to another antihistamine, or to any other medicine.

How to take cetirizine

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

• Recommended doses of cetirizine are:
  

  • For adults and for children aged over 12 years: 10 mg taken once a day.

  • For children aged 6-11 years: 5 mg taken twice daily.

  • For children aged 2-5 years: 2.5 mg taken twice daily.

• If you are giving cetirizine 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 age of your child.

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

• If you forget to take a dose, don't worry, just take the next dose when it is needed and then continue as before. Do not take two doses together to make up for a forgotten dose.

Tirer le meilleur parti de votre traitement

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

• Although cetirizine 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 on cetirizine, be aware of its effects on you and do not drink more than moderate amounts. Alcohol can increase the risk of side-effects from antihistamines.

• Si vous devez subir une opération, un traitement ou des tests (en particulier s'il s'agit de tester une allergie), n'oubliez pas de préciser que vous prenez un antihistaminique.

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