Levocetirizine for allergy

• 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 or 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.

If you experience any other symptoms which you think may be due to the medicine, speak with your doctor or pharmacist for further advice.

• Keep all medicines out of the reach and sight of children.
• Store in a cool, dry place, away from direct heat and light.
• 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.
