Clarityn allergy 10mg tablets belong to a group of medicines known as antihistamines. Antihistamines help to reduce allergic symptoms by preventing the effects of a substance called histamine, which is produced in the body. The tablet relieves symptoms associated with allergic rhinitis (eg hayfever) such as sneezing, runny or itchy nose & burning or itching eyes. The tablet may also be used to help relieve symptoms of urticaria (itching & redness), which is often known as hives or nettle rash. As an alternative, doctors can also prescribe medication that can assist with your hayfever. Please visit our Online Doctor service to proceed with an hayfever consultation. Our UK registered GP will review your details & if appropriate can provide a prescription for the main treatments for hay-fever. Click Here
