What this medicine is for

This medicine contains Cetirizine Hydrochloride, which belongs to a group of medicines called antihistamines that act to relieve the symptoms of allergic reactions.

It can be used to treat the symptoms of hayfever (e.g. runny and itchy nose and eye irritation), and year round runny and itchy nose and eyes. These allergies may be caused by pollen, dust mites, animals or moulds. Sometimes the symptoms may be caused by pollution, poor air conditioning, central heating or hot weather.

It can also be used to treat raised, red itchy skin (symptoms of urticaria, which is often known as hives or nettle rash).
