Loratadine (Clarityn) vs Cetirizene (Piriteze, Zirtek) tablets What is the difference? Loratadine and Cetirizene are the two most common over-the counter treatments for allergies producing very similar results. They are both known as anti-histamines. They work by calming the body’s immune system to allergens. Some people react better to one type of medicine than the other (we sell them both) so we cannot suggest which is better so would simply state that you try them both and see what works best for you.

Suitable for adults and children aged 6 years and over. Cetirizine dihydrochloride can also be taken for allergic skin reactions such as rash, itching and urticaria (more commonly known as Hives or Nettle Rash). Cetirizine dihydrochloride One-a-day 10mg tablets help prevent the symptoms associated with hayfever and high pollen counts as well as other allergic reactions caused by pets and dust mites.
