What this medicine is for

This medicine contains Loratadine which belongs to a group of drugs called antihistamines, which act to relieve the symptoms of some allergies.

It can be used to relieve the symptoms of hayfever (e.g. sneezing, runny and itchy nose and eye irritation) and other allergies such as pet and dust allergies. It can also be used to treat raised, red itchy skin (symptoms of urticaria, which is often known as hives or nettle rash).

This medicine can be taken by adults and children aged 12 years and over. This medicine can also be taken by children of 2 to 11 years of age who weigh more than 30 kg (see “How to take this medicine”). However, some people should not take this medicine or should seek the advice of their pharmacist or doctor first.
