Zirtek Oral Solution contains Cetirizine, a non-drowsy antihistamine used for the relief of the symptoms of hayfever (seasonal allergic rhinitis) and allergies such as dust or pet allergies (perennial allergic rhinitis) and rashes associated with hives and itching (chronic idiopathic urticaria).

Antihistamines treat hay fever and allergies by blocking the action of the chemical histamine, which the body releases when it thinks it is under attack from an allergen. This prevents the symptoms of the allergic reaction from occurring.

• Antihistamines are the first line treatment for any person suffering from allergies.

• They are effective against all allergy symptoms, especially sneezing and runny noses.

• Antihistamines are usually effective at treating itching, sneezing and watery eyes, but they may not be very effective at clearing a blocked nose.

Zirtek Oral Solution is available in a 200ml bottle as a banana flavoured liquid.

Adults and children 12 years old and over: 10mg once daily as 10ml oral solution (2 full measuring spoons).
