Levocetirizine for allergy

About levocetirizine

Levocetirizine is an anti-allergy medicine. It stops the effects of a 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.

Orticaria is a condition where an itchy skin rash develops. The rash can be triggered by an allergy to a substance such as a soap or a detergent.

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 levocetirizine it is important that your doctor knows:

• Se sei incinta o stai allattando.

• Se hai problemi con il funzionamento dei tuoi reni.

• Se hai l'epilessia.

• Se hai un raro disturbo ereditario del sangue chiamato porfiria.

• Se stai assumendo o utilizzando altri medicinali. Questo include qualsiasi medicinale che stai assumendo e che è disponibile per l'acquisto senza prescrizione, così come i medicinali a base di erbe e complementari.

• If you have ever had an allergic reaction to another antihistamine, or to any other medicine.

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

• The usual dose for adults and older children is one (5 mg) tablet daily. If it is for a younger child (aged 2-6 years), they are likely to be prescribed liquid medicine, so check the label on the bottle carefully to make sure you give the correct dose for the age of your child.

• Most people take levocetirizine in the morning, but you can take it at whatever time of day you find easiest to remember. Try to take your doses at the same time of day, each day, as this will help you to remember to take them regularly. You can take levocetirizine either before or after a meal. The tablets are best swallowed with a drink of water.

• If you have been given the liquid medicine, an oral dose syringe will be included in the pack. This is to measure out the dose. Put the tip of the syringe into the medicine and draw the plunger up to the mark which corresponds to the dose prescribed. Remove the syringe from the bottle and empty its contents on to a spoon or into a small glassful of water. The medicine can be swallowed either undiluted, or diluted with water. Remember to rinse the syringe with water after using it.

• If you forget to take a dose at your usual time, take it as soon as you remember. If you do not remember until the following day then leave out the forgotten dose from the previous day and take the dose that is due that day. Do not take two doses at the same time to make up for a missed dose.

• Many people only need to take an antihistamine when they have symptoms. Unless you are told otherwise, you should stop taking levocetirizine once your symptoms have eased.

• Although levocetirizine is classed as a non-drowsy antihistamine, it can still cause drowsiness in a few people. If this happens to you, do not drive and do not use tools or machines.

• If you drink alcohol while you are on levocetirizine, 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.

• If you are having an operation, or any treatment or tests (particularly if it is to test for an allergy), make sure you say that you are taking an antihistamine.

• If you buy any medicines 'over the counter', check with a pharmacist that they are suitable to take with an antihistamine. This is because a number of other medicines can increase the risk of side-effects.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains the most common ones associated with levocetirizine. 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 continue or become troublesome.

Se si verificano altri sintomi che ritieni possano essere dovuti al medicinale, parla con il tuo medico o farmacista per ulteriori consigli.

• Tenere tutti i medicinali fuori dalla portata e dalla vista dei bambini.

• Conservare in un luogo fresco e asciutto, lontano da fonti di calore e luce diretta.

• The liquid medicine only keeps for three months once the bottle has been opened. Do not store it or use it for longer than this.
