Piriteze tablets are an effective treatment for allergic symptoms (runny or itchy nose with or without stuffiness) caused by hayfever and other allergies e.g. pet and house dust mite allergies. Piriteze can also be taken to relieve the rashes and itching of chronic urticaria (hives). Urticaria can occur as a persistent condition and is recognised by the formation of raised white or reddish lumps surrounded by red inflamed areas which itch or sting.
